Estimate & Surface Identification: the full procedure

Walk the property, identify each surface, and confirm the cleaning method before any equipment comes off the truck.

• Applies to: Estimator, Lead Technician
• Frequency: Every job, before work begins
• Scope: Covers measuring the property, classifying each surface, and selecting soft-wash versus high-pressure per surface. Surface-damage risk, chemical selection, and dwell times defer to the product label/SDS and the business safety plan.

What you need

• Tape measure or measuring wheel
• Camera/phone for documentation
• Surface ID checklist
• Estimate form
• Moisture/surface test spot
• Flashlight

The procedure, step by step

1. Greet and confirm scope — Meet the customer, confirm exactly which surfaces they want cleaned, and listen for problem areas like recurring algae, oil stains, or oxidation.
2. Measure each surface — Record square footage or linear footage for every surface separately — driveway, walkways, siding, deck, roof, fence — so each can be priced and timed independently.
3. Classify the substrate — Identify the material of each surface (concrete, brick, vinyl, wood, composite, stucco, asphalt shingle) and note its condition, age, and any existing damage.
4. Select the method per surface — Decide soft-wash versus high-pressure for each surface. Default delicate substrates (siding, roofs, painted/wood surfaces) to soft-wash; reserve high pressure for hard flatwork like concrete. Method-versus-damage judgment defers to the label and safety plan.
5. Flag hazards and access — Note ladder/roof access points, slope, nearby electrical, plants, vehicles, and the nearest water source and storm drain.
6. Photograph existing conditions — Photograph pre-existing stains, cracks, oxidation, and damage so they cannot later be attributed to the wash.
7. Identify runoff path — Trace where rinse water will flow and note any storm drain that must be protected. Containment requirements defer to EPA and local stormwater rules.
8. Confirm and record — Summarize the surfaces, methods, and any exclusions back to the customer and capture it on the estimate form.

Quality check before you finish

• Every surface measured and recorded separately
• Soft-wash vs high-pressure decision documented for each surface
• Pre-existing damage photographed and noted
• Water source and storm-drain location identified
• Delicate substrates defaulted to soft-wash
• Access hazards (ladder/roof/electrical) flagged
• Customer confirmed scope and exclusions

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Pressure Washing business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.
