How to start or buy a window cleaning, pressure washing & exterior detailing

Q: How much does it cost to start a window cleaning, pressure washing & exterior detailing?

Starting an independent window cleaning, pressure washing & exterior detailing typically requires $50,000–$145,000 (1–2 trucks/trailers with hot-water pressure washer, soft-wash proportioner, DI/RO water-fed pole system, and holiday light stock). The largest line-item startup expenses are Service Truck/Van or Skid Build with Hot-Water Pressure Washer & Soft-Wash Rig ($25,000–$72,000), Working Capital, CRM/Satellite Quoting Software & Local Marketing ($11,000–$27,000), Initial Q4 Commercial LED Holiday Lighting Spools, Clips & Timers ($6,000–$22,000). Founders should budget for both initial buildout/equipment CapEx and 2–6 months of working capital runway.

Q: How much do window cleaning, pressure washing & exterior detailing owners make and what is a healthy profit margin?

Established window cleaning, pressure washing & exterior detailing operators generate $240,000–$1,100,000 in annual gross revenue (Spring/summer window & soft-wash jobs ($350–$950) + Q4 holiday lighting packages ($1,200–$3,500 per home)) with an owner cash flow of 28%–42% SDE margin (Adding Q4 custom-cut LED holiday lighting (lease/storage model) turns winter into the highest-margin quarter of the year). Key operating ratios include Cleaning Surfactants, Sodium Hypochlorite, DI Resin & Holiday Light COGS: 6%–12% of revenue; Exterior Cleaning & Installation Technician Payroll: 24%–32% of revenue; Truck Fuel, Pump Maintenance & General Liability Insurance: 7%–11% of revenue. Remember that gross revenue is top-line sales before payroll, COGS, and occupancy—not net owner take-home pay.

Q: How is a window cleaning, pressure washing & exterior detailing valued when buying or selling an existing business?

Operating window cleaning, pressure washing & exterior detailing resales typically trade at 2.2x–3.4x SDE (Higher multiples for operators with recurring commercial storefront routes and renewing holiday lighting clients), translating to typical acquisition prices of 2.2x–3.4x SDE ($148,000–$1,571,000). Key buyer due-diligence priorities: Audit recurring revenue: count bi-annual residential club members, storefront routes, and stored holiday light clients. Inspect pressure washer GPM/PSI pumps, burner coils, RO/DI membrane filters, and vehicle condition.

Q: Is it better to start an independent window cleaning, pressure washing & exterior detailing or buy a franchise?

An independent window cleaning, pressure washing & exterior detailing costs $50,000–$145,000 to launch and pays 0% ongoing royalties, whereas comparable franchise systems (Budget Blinds, Mr. Handyman, Five Star Painting, HouseMaster) require $73,878–$489,775 in disclosed Item 7 opening investment plus 6%–8% of Gross Sales + 2% marketing (e.g., Window Genie / Shack Shine). Franchising provides brand playbooks and vendor programs, while independent ownership preserves full margin control and exit flexibility.

Total pre-tax cash flow available to a full-time owner-operator as a % of annual revenue: Net Profit + Owner’s Salary/Draws + Interest, Taxes, Depreciation & Amortization (EBITDA) + verified one-time owner add-backs.: 28%–42% SDE margin
Resale Valuation Multiple
Typical market purchase price of an established operating business expressed as a multiple of annual Owner SDE (e.g., 2.5× SDE on $200,000 cash flow = $500,000 valuation).: 2.2x–3.4x SDE
Typical time to breakeven: 2–6 months

Three paths into this business: Start Independent vs. Buy Existing vs. Franchise for Window Cleaning, Pressure Washing & Exterior Detailing

Path 1 · Build from Scratch

Start Independent

$50,000–$145,000

Ongoing royalties: 0% ongoing franchise royalty
Time to breakeven: 2–6 months
Tradeoffs: 100% control over pricing, vendor selection, and territory with 0% ongoing royalties—preserving the full 28%–42% SDE margin target owner cash flow once ramped. Capital is concentrated upfront in Service Truck/Van or Skid Build with Hot-Water Pressure Washer & Soft-Wash Rig ($25,000–$72,000) and Working Capital, CRM/Satellite Quoting Software & Local Marketing ($11,000–$27,000); Required compliance includes EPA Clean Water Act Storm Drain Wash-Water Recovery & Runoff Compliance (2–6 months typical breakeven).

Path 2 · Acquire Cash Flow

Buy an Existing Resale

2.2x–3.4x SDE ($148,000–$1,571,000)

Ongoing royalties: 0% ongoing franchise royalty (if independent)
Timeline: 45–90 days closing (immediate Day-1 cash flow)
Tradeoffs: Immediate Day 1 revenue (typically $240,000–$1,100,000 for established operators) with trained staff, permits, and vendor accounts in place. Priced at 2.2x–3.4x SDE (Higher multiples for operators with recurring commercial storefront routes and renewing holiday lighting clients), typically financed via SBA 7(a) with 10%–20% down. Priority due diligence: Audit recurring revenue: count bi-annual residential club members, storefront routes, and stored holiday light clients.

Path 3 · Franchise System

Buy a Franchise

$73,878–$489,775

Ongoing royalties & fees: 6%–8% of Gross Sales + 2% marketing (e.g., Window Genie / Shack Shine)
Disclosed FDD median brand revenue: $774,915 (across 8 catalog brands)
Tradeoffs: Turnkey brand recognition, national vendor contracts, and playbooks across 8 FDD systems (including Budget Blinds, Mr. Handyman, Five Star Painting), but ongoing royalties and ad fund fees (6%–8% of Gross Sales + 2% marketing (e.g., Window Genie / Shack Shine)) come directly out of top-line gross sales and compress net owner take-home compared with an independent window cleaning, pressure washing & exterior detailing.

SBA 7(a) underwriting & payback takeaway:

At $675,000 revenue and 35% SDE margin ($236,250/yr pre-debt cash flow), buying an existing window cleaning, pressure washing & exterior detailing at 2.8× SDE ($661,500) generates $145,205/yr from Day 1 (2.59× DSCR), giving an immediate $1,124 Year-1 cash-flow advantage over building from scratch during a 4-month ramp-up. Once ramped in Year 2+, building from scratch ($97,500 CapEx) nets $222,831/yr (17.61× DSCR). By comparison, a 6% gross-sales franchise royalty on $675,000 revenue deducts $40,500/yr directly from owner cash flow.
