10 Questions to Ask Before Hiring a Pressure Washing Company in Jacksonville FL (Most Skip #7)
Quick Overview
The #1 mistake Jacksonville homeowners make when hiring a pressure washing company is asking only about price. In Jacksonville’s largely unregulated exterior cleaning market, the cheapest quote often comes from an uninsured operator using the wrong method on your roof or siding, producing temporary results that cost more to fix than you saved. These 10 questions separate professional Jacksonville pressure washing companies from the rest.

Question 1: Are You Licensed and Insured? Can You Provide the Certificate?
Florida does not require a specific pressure washing license beyond a standard business license — meaning literally anyone can operate. What matters is general liability insurance. Ask for the certificate specifically — not just a verbal confirmation. Professional companies carry $1M–$2M minimum. An uninsured operator working on your property leaves you personally liable for any damage to your home, a neighbor’s property, or injury on your premises.

Question 2: What PSI Do You Use on Asphalt Shingle or Tile Roofs?
The answer must be: under 500 PSI. ARMA — the Asphalt Roofing Manufacturers Association — explicitly prohibits high-pressure washing of asphalt shingles. It strips granules, accelerates aging, and voids most manufacturer warranties. Any company quoting “roof cleaning” without specifying low-pressure soft wash methodology is a red flag.
Question 3: What Chemistry Do You Use for Mold and Algae?
Professional answer: Sodium hypochlorite at calibrated concentration with surfactant. This is what ARMA recommends and what kills Gloeocapsa magma and algae at the cellular root. Vague answers (“we use the good stuff”) indicate limited chemical knowledge.

Question 4: Do You Provide a Written Estimate Before Work Begins?
Yes is the only acceptable answer. Written estimates prevent day-of price changes, scope creep, and disputed charges. Every professional Jacksonville pressure washing company provides written estimates as standard. If they resist putting their price in writing, don’t hire them.
Question 5: How Do You Protect My Landscaping and Plants?
Professional answer: Pre-wet all landscaping within drift distance before chemical application. Post-rinse all plant material after treatment. A company that dismisses this question has killed customers’ landscaping before.
Question 6: Do You Have Experience With Oak Tannin Staining?
This Jacksonville-specific question immediately reveals whether a company knows the local market. Professional answer: Alkaline pre-treatment chemistry specifically for tannin before the pressure wash pass. If they’ve never heard of oak tannin, they haven’t been cleaning Jacksonville driveways long enough.
Question 7: What Happens if Your Work Damages My Property? (The One Most People Skip)
This is the most important question — and most homeowners are too polite to ask it. Professional answer: A company with proper general liability insurance will describe how their claims process works. If they hesitate, get defensive, or claim damage never happens — that’s a serious red flag. A company with proper insurance has nothing to fear from this question.
Question 8: Can You Show Me Recent Before-and-After Photos From Jacksonville Jobs?
Request actual job photos — not stock imagery — from properties similar to yours in Jacksonville FL. The biological growth profile in Jacksonville is specific. Photos from other Florida cities don’t tell you how a company performs in Jacksonville’s conditions.
Question 9: Do You Provide Documentation for HOA Purposes?
Even if you’re not currently facing an HOA violation, before-and-after photos dated and formatted for HOA submission protect you if an inspection follows your cleaning. Professional companies include this at no extra charge.
Question 10: What’s Your Response Time if I Have a Problem After the Job?
A professional company stands behind their work. The answer you want: a direct response mechanism (phone number, email) and a clear commitment to address legitimate post-service issues.
