Cost to Start a Soft Wash & Exterior Cleaning Business (Free Calculator)
You can start a soft wash and exterior cleaning business for as little as $1,000–$1,500 with a 12V pump sprayer, hose reel, and starter chemical stock — enough for single-story home washes. A full-time setup with a dedicated trailer rig and truck runs about $14,000–$23,000, and a truck-mounted system with commercial capability for multi-story and HOA accounts pushes it to $20,000+.

The honest range: $1,000 to $20,000+ per tier
Soft washing’s range on “how much does it cost to start” comes down to rig setup and job capacity — single-story homes need only a pump sprayer; full-time volume needs a dedicated trailer rig and truck; and multi-story or commercial accounts need a truck-mounted system with larger tanks.
Most operators start with a pump sprayer on single-story homes, then invest in a trailer rig once they’re booking multiple jobs a week.
Tier 1 — Bootstrap (~$1,000–$1,500)
A 12V pump sprayer, hose reel, and downstreamer — enough to start washing single-story homes with a basic chemical stock.
- 12V pump sprayer & wand (~$350) — the core application tool
- Garden hose reel & fittings (~$150) — water supply setup
- Downstreamer & injector setup (~$150) — mixes chemical into the wash stream
- Starter chemical stock (~$200) — sodium hypochlorite and surfactant
Tier 2 — Serious Solo (~$14,000–$23,000)
The upgrade that changes the business is a dedicated soft-wash trailer rig — tank, pump, and hose reel — paired with a truck for transport, turning single-job days into multiple-job-a-day routes.
Tier 3 — Pro Rig ($20,000+)
A truck-mounted system with larger tanks and a second rig or helper lets you take on two-story homes, heavy staining jobs, and multi-building HOA or commercial contracts a trailer rig can’t handle solo.
Don’t forget the monthly number
Startup cost is the one-time hit; monthly overhead against what you charge decides whether the business works. Solo, budget roughly $80–$150/month: chemical restock and general liability insurance, plus booking/invoicing software.
The calculator turns that into a single line: how many washes it takes to break even.
Frequently asked questions
How much does it cost to start a soft wash business?
A lean start is $1,000–$1,500 — a 12V pump sprayer, hose reel, downstreamer, and starter chemical stock. That's enough for single-story home washes, which run $250–$600 per job on average.
Do you need a dedicated rig to start soft washing?
No — a pump sprayer and garden hose setup can wash single-story homes. A dedicated trailer rig with a tank, pump, and hose reel becomes worth the investment once you're booking multiple jobs a week and need faster setup and larger chemical capacity.
What equipment do you need to start a soft wash business?
The non-negotiables are a pump sprayer, hose reel, downstreamer, and chemical stock (sodium hypochlorite and surfactant). A trailer rig and truck are the Serious Solo upgrade. A truck-mounted system with larger tanks is for the pro tier's multi-story and commercial capability.
What are the ongoing monthly costs of a soft wash business?
Budget roughly $80–$150 a month solo: chemical restock and general liability insurance, plus booking/invoicing software.
Is soft washing more profitable than pressure washing?
Soft washing often carries better margins per job since it uses low-pressure chemical application rather than water volume — priced at $0.15–$0.40 per square foot of wall area, with two-story homes and heavy staining as premiums over routine maintenance washes.
