How to Vet a Pressure Washing Company in Florida (10 Questions to Ask Before Booking)

Florida has hundreds of pressure washing operators. Some are excellent fully-insured businesses with the right equipment and trained crews. Others are part-time weekend operators with a borrowed pressure washer, a Facebook Marketplace ad, and no insurance. Both will quote your house. Telling them apart matters because the wrong choice can damage your property, void your roof warranty, or leave you responsible if someone gets hurt on your job.

This guide is the questions we tell our own customers to ask — and our honest answers to each of them.

1. Are you insured?

The right answer: “Yes, $1 million general liability minimum. I can email you a certificate of insurance right now.”

A general liability policy covers property damage (broken window, damaged screen, etched paint) and bodily injury (someone slips on wet concrete and sues). Without it, any of those scenarios become your problem — and Florida homeowners’ insurance generally doesn’t cover damage caused by contractors on your property.

If they pause, hedge, or say “I have business insurance” without specifics, that’s a no. Ask for the certificate of insurance (COI). Real operators send it within minutes.

2. What method do you use for siding?

The right answer: “Soft-wash. Low pressure with a biodegradable detergent.”

Wrong answer: “High pressure washing for siding gets the best clean.” This is the giveaway. High pressure on siding (vinyl, stucco, Hardie, painted wood) strips paint, etches finish, and forces water under the surface where it causes hidden damage. Every reputable Florida pressure washer uses soft-wash for siding and reserves high pressure for concrete only.

If they offer a “house wash starting at $99,” they’re almost certainly using a single approach (high pressure) and skipping the chemistry. The result looks clean for a month then needs to be redone.

3. What about the roof?

The right answer: “Low-pressure soft-wash only. Never high pressure on a roof — it voids the warranty and damages the shingles.”

Every major shingle manufacturer (GAF, Owens Corning, CertainTeed) explicitly prohibits pressure washing roofs. ARMA (Asphalt Roofing Manufacturers Association) endorses only the low-pressure soft-wash method. A pressure washer who quotes “roof pressure washing” without specifying soft-wash is either uninformed or willing to damage your roof to make the sale.

4. How do you protect my landscaping?

The right answer: “We pre-wet beds before applying any cleaning solution and rinse them again after. Detergents are biodegradable and break down quickly.”

This is a tell. Operators who actually do good work know the answer cold because they do it every job. Operators who skip the step (or don’t know about it) will give a vague answer or claim “the chemicals are fine for plants.”

Florida landscaping in particular — mature oaks, azaleas, hibiscus, palms — is sensitive to high-concentration sodium hypochlorite. Pre-wetting and post-rinsing matters.

5. Do you give a written, fixed quote?

The right answer: “Yes, the quote you receive is the price you pay. If the scope changes, we stop and call you before continuing.”

Avoid: “We’ll give you a rough estimate and finalize on the day.” This is the setup for the day-of upsell (“turns out it’s bigger than expected, that’s another $300”). A reputable operator quotes from photos (or in person), commits to the price, and only changes it if you ask for additional work.

We quote by photo and text — most jobs in Polk County never need an in-person visit. Send a few photos of the property, get a same-day fixed quote, schedule.

6. How long have you been operating?

The right answer is honest, whatever it is. New operators can be excellent; long-tenured operators can be sloppy. What you’re listening for is consistency between what they say and what their reviews say. A “10 years of experience” claim from someone with a Google profile registered 4 months ago is a flag.

In Polk County, check Google Reviews, Facebook, and the BBB for the business name. A 2-3 year history with 30+ reviews tells you more than a “20 years experience” claim with no online footprint.

7. Do you have a phone number and is it answered?

This sounds obvious but it filters fast. A real business has a phone number that gets answered (or returns the call within an hour). Operators who only respond by Facebook Messenger or who don’t return a phone call within a business day are part-time at best.

Our office number is (863) 887-6769 and is answered during business hours; outside-hours messages get returned the next morning.

8. What’s your warranty or guarantee?

The right answer varies but should be specific. We offer:

• 24-month spot-treatment warranty on roof cleanings (if streaks return in the warranty period, we re-treat the affected area at no charge)
• Same-visit re-clean on house washes (if any spot doesn’t look right when we walk the property with you at the end, we re-wash it before leaving)
• Combo-pricing guarantee (the quoted combo price is the price even if the work runs long)

A vague “satisfaction guarantee” without specifics is meaningless. Ask what specifically the guarantee covers and for how long.

9. Are you a business or a side hustle?

This is direct but matters. A registered business has:

• A business address (even if home-based, it’s registered)
• A Florida sales tax license if applicable
• W-2 or 1099 paperwork for crew
• Worker’s comp coverage if they have employees

A side-hustle operator might be perfectly competent but if anything goes wrong — damage to your property, injury on your job, tax disputes — the recourse is limited. For a one-time low-stakes job that might be fine. For a combo package costing $1,000+, it’s not.

10. Can I see a recent job in my neighborhood?

If you live in Lakeland, Winter Haven, Bartow, or anywhere in Polk County, a real operator can name multiple recent jobs nearby. Sometimes they can drive you past one. References from neighbors, recent online reviews mentioning specific streets or neighborhoods, or Google Map listings tied to specific addresses — all signals of an actually-working business.

A pressure washer who can’t name a recent local job is either brand new (legitimate) or pulling leads from out of the area (less legitimate).
