Get the legal business name and Washington contractor registration number. Check current status with L&I, not just a badge on a website. L&I includes pressure washing decks, roofs and buildings in work requiring registration. Ask L&I about any claimed exemption for your exact job.
Check the L&I recordRequest proof of liability coverage for the work, and confirm it with the insurer. If a crew will do the job, check workers’ compensation status too; an owner working alone may not need an account. A business license, contractor bond and liability insurance are different things; none guarantees workmanship.
Ask two or three providers to quote the same surfaces and approximate size. Include access, stains, water supply, cleaning method, wash-water handling, total price and applicable tax. Clarify whether gutters, stain treatment, sealing or moving furniture cost extra.
Ask why their method suits your material, whether they’ll test a small area, and how they’ll protect plants, outlets, windows and existing damage. “Soft wash” is not a guarantee of safety. Ask where dirty water and cleaning products will go; “biodegradable” does not make drain disposal okay.
Find the right question for your surfaceLook for recent, detailed reviews and photos of similar surfaces. Ask who will actually arrive. Agree on timing, deposit, cancellation, weather delays and a final walkthrough. Put changes in writing; avoid paying the full amount before the work is complete.
METHOD MATTERS
Choose the surface you want cleaned. The right answer should fit its material, condition and manufacturer’s care instructions.
These are hiring questions, not DIY pressure settings or chemical recipes.
Ask: “Will you check the concrete’s age, condition and sealer, and test for etching?”
Have oil, rust and other stubborn stains priced separately. Ask how dirty water will be contained and disposed of, especially near a curb or storm drain. A clean surface may still show old stains.
Ask: “What does the siding manufacturer allow, and how will you keep water out of seams and openings?”
Low-pressure methods may be appropriate, but material and paint condition matter. James Hardie advises against high-pressure washing its fiber-cement products. Loose paint or suspected lead paint needs a separate plan before washing.
Ask: “Will this method damage wood fibers, the finish or joint sand?”
Have the provider identify the exact decking product and follow its care guide. Pressure-washing limits vary even between composite product lines. For pavers, ask whether replacing lost joint sand or resealing is included.
Ask: “Is this roof-cleaning method approved by the roofing manufacturer?”
Asphalt shingles should not be pressure washed. Ask about roof-safe treatment, plant protection, runoff and fall protection. Avoid aggressive scraping or a promise to blast all moss off immediately.
THE LOCAL DETAILS
Storm drains can lead to local creeks and lakes. Bellevue’s guidance calls for cold-water, soap-free pressure washing and keeping wash water out of storm drains. Ask your provider to check the rules for your city and job before starting.
Bellevue pollution preventionFor a condo, townhome or HOA property, confirm who controls the surface and whether approval is needed. Check work hours, parking, shared drains, water access and any certificate-of-insurance requirements before booking.
Point out shaded, mossy areas, slopes and delicate landscaping. Agree on weather rescheduling and how walkways will be left safe. If sealing is included, ask about the product’s required drying time and weather window.
