Starting a Window Cleaning Company: From Idea to Open

Starting a Window Cleaning Business: What to Do First

You’ve stared at streaky glass, grabbed a squeegee, and thought, “I could do this better.” Many of us have. The draw is clear—low startup gear, clean before-and-after results, and work you can start small and grow.

But a business isn’t just washing panes. It’s choosing a model, setting safe limits, and launching legally with the right tools and paperwork. This guide walks you through the steps to open with confidence—and without surprises.

We’ll stay focused on pre-launch. You’ll make decisions, gather proof, and line up gear so day one feels steady, not rushed.

Pre-Start Foundations

Start with your life, not your ladders. Window cleaning is physical. It means weather, heights, and travel between jobs. If you’re not sure it fits, pressure-test the idea before spending money.

Ask simple questions. Who will hire you first? Why would they pick you over a competitor? Can your family back your schedule—especially early mornings, evenings, or weekends?

Use these reads to get clear before you commit:

Fit check: Heights OK? Outdoor work in heat and cold OK? Comfortable with ladders and tight deadlines? If not, consider limiting scope to ground-level and interiors or plan to hire for high-reach work.

First customers: Prioritize residential blocks, small retail storefronts, and low-rise offices. Route work builds fastest when travel is short and repeat cycles are clear.
Why you: Clean, safe, insured, on time—plus extras like screens, tracks, and hard-water stain removal. Simple, honest positioning wins early trust.

Skills You Need

Two sets matter here: running the business and doing the work. You can learn both, but be honest about gaps. Where you’re not ready, plan training—or hire.

Set written standards early. It keeps quality steady when you’re busy and makes training easier later.

Use this as a checklist to learn or outsource.

Business skills: quoting and scope writing, basic bookkeeping, scheduling and routing, customer service, time estimates, simple copy and photos for your site and listings.
Safety skills: ladder selection and setup, fall-risk awareness, hazard checks around doors, pedestrians, pets, soft ground, and power lines.
Technical skills: squeegee technique, water-fed pole work, pure-water use and Total Dissolved Solids checks, stain identification (mineral, paint, tape), screen and track cleaning, gasket and frame care to avoid damage.
If you don’t have it yet: take short skills training, shadow a pro, or hire a trained tech for high-reach work until you’re ready.

Research the Business

Don’t guess. Map your market, test prices, and learn local rules before you buy gear. You’re looking for clear demand, simple routes, and services people ask for again and again.

Use competitor quotes to set guardrails. Then match your offer to the buildings you’ll see most—homes, small retail, and low-rise offices.

For the bigger picture, see Supply and Demand and Pricing Your Products and Services.

Market size: Count rooftops and storefronts in target zones. Note building heights and access—ladders vs. water-fed pole reach.
Target clients: residential owners, property managers, retail tenants, and small offices. Define frequency: one-time, spring/fall, quarterly storefronts, or monthly maintenance.
Competitors: list 5–10, capture prices, response time, add-ons, and guarantees. Look for gaps you can fill—like reliable schedules or clear prep instructions.
Service scope: windows in/out, screens, tracks, skylights, mirrors, glass doors, solar panels, light fixtures, basic gutter cleaning. Decide now what you will and won’t do.
Pricing models: per-pane plus extras, or time-and-materials with a minimum. Create a simple pricing template so quotes are consistent.

Business Model & Planning

Pick a position you can deliver—clean, safe, and on time. Keep packages simple. Add clear upsells customers understand at a glance.

Write your plan to guide day-one choices. It doesn’t need to be long—just practical and specific.

Use How to Write a Business Plan for structure and Building a Team of Professional Advisors if you want a CPA or attorney to review.

Positioning: “Low-rise residential and storefront specialists. Safe ladder work and pure-water results.”
Packages: Basic (exterior only), Standard (exterior + screens), Premium (exterior + interior + tracks). List exclusions like scratch removal on tempered glass.
Upsells: hard-water stain removal, skylights, mirrors, chandelier cleaning, solar panels, seasonal gutter cleaning.
Financial assumptions: target jobs per day, average ticket, repeat frequency, travel time, and fuel. Set a simple weekly break-even number.

Write a Lean Business Plan

Keep it on one or two pages. Update it after your first test jobs. It’s a tool, not a trophy.

Who you serve first, where you’ll work, and what you’ll include.
How you’ll price, quote, and schedule.
Startup gear list and one-time costs vs. recurring costs.
Proof steps: test jobs, photos, and testimonials before launch.

Funding

You can start lean. Most new owners self-fund tools and a used vehicle setup. Add pure-water gear when demand supports it.

If you borrow, keep it small and tied to assets—vehicle or equipment. Compare total cost of ownership before you sign.

Use an advisor if you’re unsure. A short call with a CPA can save you from expensive mistakes.

Estimate needs: ladders, poles, squeegees, buckets, cloths, PPE, vehicle racks, water-fed cart (optional at first), software, branding, insurance deposits.
Sources: savings, small personal loan, equipment financing, or a small bank line secured by the vehicle.
Banking: open a business account and separate cards before your first purchase. It keeps your books clean.

Legal & Compliance

Register the business, handle taxes, and confirm local rules before you take payment. Choose a simple structure you can manage. Many start as a sole proprietorship or a limited liability company.

If you expect partners or investors, define roles and ownership now—before money changes hands. Written agreements prevent conflict later.

Use How to Register a Business and Business Insurance as quick primers while you work through filings.

Entity formation: choose and form your entity with your state’s Secretary of State. If using a trade name, file an assumed name (DBA) where required.

Employer Identification Number: apply online with the Internal Revenue Service for free; keep the confirmation letter for your bank.

Sales and use tax: some states tax cleaning services. If taxed, register with the state Department of Revenue before you invoice.

Local business license: many cities or counties require a general business license. If working from home, check for a home-occupation permit.

Right-of-way use: if you’ll stage ladders or cones on sidewalks or curb lanes, ask about a temporary right-of-way or encroachment permit.

Environmental rules: manage wash water. Don’t discharge to storm drains. Ask your city about approved disposal, often the sanitary sewer with conditions.

Workplace safety (if you have employees): train on ladders and walking-working surfaces, keep Safety Data Sheets, and label chemicals.

Workers’ compensation: required in many states when you have employees. Check thresholds and timing for your state.

Commercial vehicle: confirm weight and use. A typical van or pickup rarely needs a U.S. Department of Transportation number unless it meets commercial motor vehicle thresholds—verify specs if you cross state lines.

Leased workspace: if you rent a small shop or warehouse, confirm the Certificate of Occupancy (CO) covers your use and storage.

Varies by jurisdiction: Verify with the right office—Secretary of State: entity filing and assumed name/DBA. State Department of Revenue or workforce agency: sales tax registration and employer accounts. City or county licensing and public works: business license, home-occupation, and right-of-way rules. Stormwater or wastewater utility: wash-water disposal rules.

Quick Agency Calls—Smart Questions

Keep calls short and specific. Take names, dates, and notes.

Secretary of State: “What’s the online filing path for a limited liability company?” “Where do I check name availability?” “Do I need a registered agent for a home-based business?”
Department of Revenue: “Are window cleaning services taxable in this state?” “How do I register for sales and use tax?” “What’s the filing frequency for small service businesses?”
City licensing: “Do I need a general business license if I’m mobile?” “Are there home-occupation limits on vehicle parking or material storage?” “What’s the permit for placing ladders or cones on sidewalks during storefront work?”
Stormwater/wastewater utility: “How should I manage window wash water?” “Is discharge to the sanitary sewer allowed with pre-filters?” “Do you have a mobile washing best practices sheet?”

Brand & Identity

Pick a name people remember. Check that it’s available at the state, the domain is open, and you can grab matching social handles.

Build a simple identity kit—logo, colors, and a few photo guidelines. Keep it clean and consistent across your vehicle, cards, and site.

Use these guides as you build: How to Build a Website, Business Cards, Business Sign, Corporate Identity Package, and Create a Marketing Plan.

Name check: search your Secretary of State site and do a basic web search for conflicts. Then check social handles and domain.
Website: A simple one is fine at launch—services, service area map, photos, insurance note, and a simple request-a-quote form.
Vehicle branding: door lettering or magnets with phone and URL. Confirm local sign rules if you park a branded vehicle at home.

Equipment & Software

Buy only what you’ll use in your first 60 days. Add advanced gear as demand grows. Keep safety first—quality ladders, stabilizers, and personal protective equipment.

Below is a detailed list you can print and check off. Adjust quantities to your crew size and service scope.

Organize gear in bins and racks so load-in and load-out are fast and safe.

Field cleaning tools: squeegees (assorted channels and rubbers), T-bar and sleeves, scrapers with approved blades, microfiber and detailing towels, non-abrasive pads, buckets with bucket-on-a-belt, extension poles.
Pure-water system (for exterior work): deionization or reverse-osmosis cart, hoses and quick connects, water-fed poles sized to typical building heights, inline Total Dissolved Solids meter.
Access and safety: stepladders and extension ladders (ANSI-rated), ladder levelers and stand-offs, stabilizers, ladder mitts, tool lanyards, cones or folding signs, first-aid kit, gloves, eye protection.
Chemicals and consumables: glass cleaner or pure water, hard-water mineral remover compatible with glass, labeled spray bottles, secondary container labels, paper towels or lint-free cloths.
Vehicle and transport: cargo van, pickup, or SUV; roof or ladder racks; tie-downs and straps; hose reels; storage bins; spill kit for chemicals.
Office and admin: smartphone, printer/scanner access, lockable storage for chemicals and sharp tools, basic accounting setup.
Marketing kit: business cards, door hangers or route cards, simple before/after photo kit (phone mounts and cloth backer), branded shirts or hats.
Optional add-ons: solar panel brush heads, light-fixture and chandelier cleaning tools, small gutter cleaning tools, interior window protection pads for furniture and floors.

Software to Consider

Use simple tools you’ll actually open every day. Start light, then upgrade as routes grow.

Scheduling and routing: calendar with route mapping, recurring job reminders, and arrival windows.
Quoting and invoicing: templates, photo notes, e-signature for approvals, and integrated payments.
Accounting: income and expense tracking, mileage log, and basic financial reports.
Customer management: follow-up reminders, review requests, and service history.
Safety and compliance: Safety Data Sheet storage, training log, ladder inspection checklist.
Document storage: insurance certificates, business license, and vehicle registrations for quick sharing with property managers.

Physical Setup

Home-based works well if storage is clean and safe. Keep chemicals locked, ladders secured, and access clear. Plan your load-in and load-out so mornings are smooth.

If you rent a small warehouse or bay, confirm the Certificate of Occupancy covers your use and storage. Ask the landlord about allowed signage and parking.

Protect customers’ spaces. Bring floor protection, corner guards, and moving blankets for interiors.

Storage: wall-mounted ladder hooks, labeled bins for sleeves and rubbers, separate cabinet for chemicals and blades.
Vehicle layout: heaviest items low and forward, tie-downs on racks and bins, drip trays for poles and hoses.
Job-site kit: cones or folding signs, door stoppers, towels for sills and floors, and a small mat for interior setups.

Insurance & Risk

Get coverage in place before your first paid job. Many property managers will ask for proof of insurance and may require to be listed as an additional insured on a certificate.

Review limits with a broker who understands field services. Compare options and keep certificates handy.

Use Business Insurance as a checklist while you collect quotes.

General liability: covers third-party bodily injury and property damage claims related to your work.
Commercial auto: for vehicles used in the business.
Tools and equipment: covers gear in transit or on site (often called inland marine or tools and equipment coverage).
Workers’ compensation: required when you employ workers in many states—check your state threshold.
Umbrella policy: consider additional limits once you work larger sites or multiple crews.
Client requirements: some sites ask for certificates with specific wording. Ask before the job so you can get the paperwork from your broker.

Suppliers & Maintenance

Pick a primary supplier for sleeves, rubbers, and poles. Keep backups so jobs don’t stall. A small monthly order keeps inventory fresh.

Set a maintenance rhythm now—clean sleeves, replace rubbers, and log ladder inspections. It protects quality and safety.

Ask for bulk pricing once you have routes in place.

Supplier accounts: open with one or two national distributors plus a local hardware store for basics.
Consumables plan: track rubbers, sleeves, and blades. Keep a labeled “ready” bin and a “to wash” bin.
Safety Data Sheets: store and carry current copies for any hazardous chemicals you use. Keep labels legible.
Ladder and gear checks: monthly inspection log; retire damaged gear immediately.

Pre-Launch Readiness

Do a few test jobs before you announce anything. Time each step. Take photos. Ask for feedback. You’re proving your flow, pricing, and finish—on real glass.

Dial in your documents. Simple quotes, clear prep notes for customers, and a clean invoice template save time when the phone rings.

Set up payments and keep the admin light. You want to focus on the work, not the paperwork.

Proof: 3–5 test jobs with before/after photos and short testimonials you can share.
Documents: quote and scope template, work order, invoice, and receipt. Add a short note on what’s excluded (for example, scratch removal on tempered glass).
Payments: card, ACH, or tap-to-pay. Test everything on your phone before launch.
Accounts: business bank login, Internal Revenue Service account, state tax account (if applicable), city license file, and insurance certificates.
Contacts: CPA and insurance broker on your phone, plus your city’s licensing and utility contacts for quick questions.

Go-Live Checklist

You’re almost there. One last pass can prevent a bad first day. Check compliance, check gear, and line up your first week of leads.

Start simple. Pick two neighborhoods or a small business district and focus your routes there. Consistency beats complexity at launch.

Ready? Run the list below and then open your calendar.

Compliance: entity formed, Internal Revenue Service Employer Identification Number received, state tax registration done if required, local business license in hand, and wash-water plan set with your city utility.
Insurance: general liability and commercial auto active; certificates ready to share; workers’ compensation in place if you have employees.
Safety: ladder and gear inspection done; Safety Data Sheets organized; job-site checklist printed; first-aid kit stocked.
Gear: squeegees, sleeves, rubbers, scrapers, extension and water-fed poles, ladders with stabilizers, cones/signs, towels, labeled spray bottles, and vehicle tie-downs.
Brand assets: website live with service area, business cards in the vehicle, simple vehicle lettering or magnets, and a small photo gallery.
Leads: shortlist of 50–100 doors or addresses, a route map, and a basic outreach script. Use your plan from Create a Marketing Plan.
People plan: if you may hire soon, review How and When to Hire and set a simple training checklist so new help learns your way.
Avoid common errors: skim Avoid These Mistakes When Starting a Small Business the night before launch.

101 Tips for Running Your Window Cleaning

Starting a window cleaning business looks simple until the details pile up—ladders, safety, pricing, and local rules. This list gives you clear steps you can use right away. Read it once, then act on the parts that match your plan and location. Keep it practical, keep it safe, and keep it documented.

Use the categories to focus. Each tip stands alone, so you can build your launch plan in the order that makes sense for you.

What to Do Before Starting

Decide your ceiling—literally. Set a maximum working height for launch and stick to it until you have the training, gear, and insurance to go higher.
Choose your starter niche: residential exteriors, storefront routes, or low-rise offices. Your first niche dictates ladder size, poles, and how you schedule.
Walk target blocks and count panes, heights, and access points. Real counts beat guesses and keep your quotes realistic.
Shadow a pro for a day or run three test cleans for friends. Time each step and note issues like soft ground, door traffic, and parking.
Set exclusions now—no scratch removal on tempered glass, no work above your height limit, no work during lightning or high winds.
Price three sample homes and three storefronts with a per-pane method and a time-and-materials method. Pick the one you can explain in one sentence.
Call your city or county licensing office to ask if a general business license or home-occupation permit is required for a mobile service.
Ask your state Department of Revenue if cleaning services are taxable. Rules vary by state, and you need the answer before invoicing.
Ask your local stormwater or wastewater authority how to manage wash water. Many places prohibit discharge to storm drains.
Get insurance quotes before you buy gear. Confirm general liability, commercial auto, and—if you’ll hire—workers’ compensation.
Plan your vehicle layout on paper. Heavy items go low and forward, ladders secured, and cones accessible the moment you open the door.
Write a simple plan: niche, service list, pricing model, gear list, proof steps, and your first 50 target addresses.

What Successful Window Cleaning Owners Do

Build route density. Cluster jobs in the same neighborhoods and business districts so travel is the exception, not the rule.
Inspect ladders weekly. Log defects, tag damaged ladders out of service, and replace worn feet and ropes.
Keep a Safety Data Sheet binder and labeled bottles. If a label wears off, the bottle is out of service until relabeled.
Do a two-minute site brief before each job: ground conditions, overhead lines, door traffic, and weather.
Photograph tricky areas before and after. Photos resolve most questions about pre-existing issues.
Use stabilizers and stand-offs to protect gutters and improve ladder angle. Better footing equals fewer incidents.
Standardize your kit. Every crew carries the same tools in the same positions so anyone can grab and go.
Schedule seasonal work in advance. Pre-book spring and fall so your calendar fills before the rush.
Track win rate, average ticket, and job time. These three numbers tell you whether pricing and routing are working.
Train with short, frequent drills. Five minutes on ladder setup or blade safety each morning compounds into real skill.

Running the Business (Operations, Staffing, SOPs)

Create an SOP for ladder setup: angle, tie-off or helper hold, door blocked, and landing checked for firmness.
Create an SOP for water-fed poles: brush pattern, rinse technique, and Total Dissolved Solids checks before and after.
Issue a stop-work authority card. Anyone can halt work when something looks unsafe—no questions asked.
Standardize your inventory: spare rubbers, sleeves, blades, towels, and clips. Restock at day’s end, not the next morning.
Label every bottle with product name and hazard warning. No label means no use.
Use cones or folding signs at doorways and public paths. Control foot traffic before you climb.
Adopt a simple time tracker for every job. Start and stop times build accurate future estimates.
Set a weather call rule. For wind or storms, cancel early with a clear reschedule window.
Write a short onboarding checklist for helpers: ladder safety, chemical labeling, door control, and tool use.
Hold a 15-minute safety chat weekly. Review one recent job and one improvement.
Pre-trip your vehicle daily: tires, lights, ladder tie-downs, and fluid leaks. Fix issues before you leave the driveway.
Build a basic incident report form. Document date, place, what happened, and what you changed to prevent a repeat.
Store blades and scrapers in a hard case. Dull or rusty blades get tossed immediately.
Keep clean and dirty textiles in separate bins. Wash microfiber without fabric softener to preserve performance.
Set recurring reminders for filter changes on pure-water systems. Track dates on the unit and in your phone.
Back up admin files weekly: quotes, photos, insurance certificates, and licenses.

What to Know About the Industry (Rules, Seasons, Supply, Risks)

Many jurisdictions prohibit wash water discharge to storm drains. Plan for capture or approved disposal to sanitary sewer where allowed.
Ladder rules apply when you employ others. Train on walking-working surfaces, ladder use, and fall risks.
If you ever use rope descent systems, building anchors must be inspected and documented by the building owner.
State rules for sales tax on services vary. Confirm whether window cleaning is taxable before you set prices.
Workers’ compensation thresholds vary by state. Check when coverage becomes mandatory if you plan to hire.
A U.S. Department of Transportation number is required for certain interstate commercial vehicles by weight or use. Most small vans do not qualify, but verify your specs.
Seasonality is real. Expect spring surges, summer slowdowns in some markets, and pre-holiday spikes.
Glass types behave differently. Tempered glass can scratch if you use the wrong blade or trapped grit; test first.
Skylights and old frames can be fragile. Extra padding and lighter pressure prevent costly damage.
Solar panels have manufacturer-specific cleaning guidance. Use soft brushes and deionized water when recommended.
Public right-of-way rules can apply when staging on sidewalks. Ask about encroachment permits for busy storefronts.
Home-occupation limits may restrict branded vehicle parking at your residence. Check your zoning language.

Marketing (Local, Digital, Offers, Community)

Claim and complete your local business listings. Use real service areas, a short services list, and clear photos.
Publish before-and-after photos that show frames, tracks, and sills. Detail shots prove quality better than wide shots.
Ask for reviews the same day you finish. One short text with a thank-you and simple instructions gets more responses.
Create three simple packages with plain language. Customers choose faster when options are obvious.
Walk storefront loops with a one-page rate sheet and proof photos. Offer to start before opening hours.
Offer route discounts for neighbors on the same day. Route work improves travel time and reliability.
Collect permission for yard signs after residential jobs. A sign for two days can fill a week of leads nearby.
Join local property manager and small business groups. A single lunch can open recurring accounts.
Use a short quote form on your site. Ask for address, number of panes, and height notes—nothing more.
Publish a service area map. People hire faster when they see their street on the map.
Run seasonal reminders in spring and before major holidays. Name the timing and the benefit to make it easy to say yes.
Offer maintenance schedules for storefronts: weekly, biweekly, or monthly. Predictable cycles help planning for both sides.
Collect simple testimonials that mention punctuality, care, and results. Those three points address most concerns.
Track the source of every lead. Double down on the channels that actually book jobs.
Use community guidelines before posting in neighborhood groups. Helpful posts outperform hard pitches.
Keep your brand consistent: same logo, colors, and voice on vehicle, cards, and website.

Dealing with Customers (Trust, Education, Retention)

Do a quick walk-through on arrival. Confirm access, pets, and any fragile items near windows.
Explain what’s included and what isn’t in plain language. Clarity prevents disputes.
Ask for parking instructions before you arrive. A good spot speeds setup and keeps neighbors happy.
Use door stoppers and corner guards inside homes. Small protections prevent big problems.
Count panes together on the first visit. Shared counts make pricing transparent.
Set weather rules in writing. If wind or lightning makes work unsafe, reschedule early and offer first choice on the next open slot.
Offer a simple maintenance plan after a one-time job. Clear frequency and price keep customers returning.
Send a thank-you message with a photo of one finished area. It reinforces quality and earns referrals.
When something goes wrong, own it fast. A direct apology and a fix beat excuses.
Keep notes on preferences: gate codes, pet names, and do-not-disturb rooms. Personal details make repeat visits smooth.

Customer Service (Policies, Guarantees, Feedback)

Set a response standard. Aim to reply to new inquiries the same day and to existing clients within business hours.
Confirm appointments with date, window, and prep notes. Clear expectations reduce no-shows.
Send a day-before reminder and an on-the-way text. People appreciate certainty.
Offer a short workmanship guarantee for visible streaks or drips spotted within a set time. Define what’s covered and how to request a touch-up.
Log feedback in one place. Tag it by topic so you can spot patterns worth fixing.
Use a simple complaint path: listen, restate, propose a fix, and confirm the resolution in writing.
Decide when to refund vs. redo. If the fix will cost more than the job, a refund may be the fast, fair outcome.
After a fix, follow up in a few days to confirm satisfaction. Closure turns a problem into loyalty.

Sustainability (Waste, Sourcing, Long-Term)

Favor pure water and minimal chemicals where feasible. It’s safer for you and simpler for disposal.
Wash microfiber separately and line-dry when possible. It extends life and keeps lint down.
Keep wash water out of storm drains. Ask your utility about approved disposal to sanitary sewer where allowed.
Reuse durable bottles with correct labels and dates. Refill only from labeled bulk containers.
Plan routes to minimize miles. Fewer trips cut fuel use and save time.
Recycle cardboard, plastic wraps, and worn textiles where local programs accept them.

Staying Informed (Trends, Sources, Cadence)

Subscribe to safety updates from national workplace safety agencies. Ladder and fall guidance changes are worth knowing.
Bookmark your state tax agency’s page for service tax rules. Check it before changing your pricing or adding services.
Read stormwater best practices from environmental regulators. Local enforcement often cites those guidelines.
Review ladder safety resources from national ladder organizations each spring. Refreshing basics prevents accidents.
Scan trade association updates quarterly for tools, techniques, and case studies you can apply.

Adapting to Change (Seasonality, Shocks, Competition, Tech)

Build a rain plan that swaps exterior work for interiors or reschedules fast. Share the plan with customers up front.
Keep a small reserve of cash and key supplies for disruptions. A cushion keeps jobs moving when deliveries slip.
Test new tools on one job before buying for the team. Prove time savings and finish quality first.

What Not to Do

Don’t set a ladder on unstable ground or near a door that can swing open. Stabilize, block, or move the ladder.
Don’t use a razor on tempered glass without testing and documenting conditions. Trapped grit can cause scratches you’ll own.
Don’t discharge wash water to storm drains or ignore local rules. Fines and call-backs erase profits.
