Soft Wash Estimate Template (Free)
A soft wash estimate needs the area by the square foot, each surface (house siding, roof, walkways) as its own line, the treatment method noted, and any add-ons like gutter brightening itemized — plus a valid-until date and acceptance line. Copy the template below, or use quoting software that converts it straight to an invoice.
Essential line items on a soft wash estimate
A professional soft wash estimate highlights safe low-pressure chemical cleaning methods, itemizes distinct exterior surfaces, and educates homeowners on plant protection protocols:

- Chemical Treatment Specifications: Low-pressure sodium hypochlorite (SH) blend (1%–2% for house siding, 4%–6% for roofs) mixed with premium surfactant soaps to break down organic mold, mildew, and algae.
- Specialty Add-Ons: Gutter exterior tiger-stripe brightening, window pure-water rinse, and rust/calcium stain removal.
- Landscape Plant Protection Protocol: Pre-soaking foliage, neutralizer overspray application, and gutter downspout bagging.

Low-pressure chemical soft washing vs. high-pressure blasting
Educating homeowners on your estimate explains why your price is superior to cheap pressure-washing operators:
- Vinyl & Aluminum Siding Soft Wash ($0.18–$0.30 per sq ft): High-pressure blasting (3,000+ PSI) forces water behind siding laps, damages window seals, and blows off paint. Soft washing applies a gentle 60 PSI chemical mix that neutralizes mold spores at the root, allowing gentle low-pressure rinsing.
- Stucco, Dryvit & EIFS Soft Wash ($0.25–$0.40 per sq ft): Porous stucco traps organic spores deep within texture crevices. High pressure tears stucco surfaces; soft washing sanitizes the substrate without surface erosion.
- Asphalt Shingle Roof Soft Wash ($0.35–$0.60 per sq ft): High pressure strips protective ceramic granules from shingles, voiding roofing warranties. Soft washing is the only ARMA (Asphalt Roofing Manufacturers Association) approved cleaning method.
Itemizing plant protection, gutter brightening, and flatwork
Enhance project ticket sizes with itemized add-on services:
- Gutter Exterior Tiger-Stripe Brightening ($1.50–$2.50 per linear foot): Electrostatic bonding causes dark vertical “tiger stripes” on aluminum gutter exteriors. Applying specialized gutter-brightening detergents and hand-scrubbing restores gutter finish.
- Landscape & Plant Neutralization: Continuous pre-wetting of flowerbeds and application of sodium thiosulfate chemical neutralizers protects delicate landscaping from chemical runoff.
- Pure-Water Window Rinse: Rinsing exterior glass with purified water prevents hard-water chemical spotting.
On-site billing workflow: Paid before coiling hoses
Convert approved estimates to paid invoices instantly upon completion:
- Post-Wash Property Inspection: Walk the property perimeter with the homeowner to review clean siding, stain-free gutters, and spotless roof lines.
- Driveway Payment Collection: Present the digital invoice on your mobile phone or tablet. Collect credit card, debit card, Apple Pay, cash, or Venmo payments on the spot.

Frequently asked questions
Should each surface be its own line?
Yes. Siding, roof, and flatwork are different jobs with different methods and risk, and itemizing them lets a customer add or drop a surface without renegotiating the whole quote.
Why note the treatment method?
Soft wash versus pressure is the whole selling point — recording the low-pressure chemical method documents that you're doing the safe, longer-lasting job a cheaper pressure-only quote isn't.
Should the estimate expire?
Yes — a valid-until date protects your pricing and gives the customer a gentle reason to book before the season fills.
