How Do You Choose a Pressure Washing Company?

Why choosing matters more than it used to

Pressure washing has almost no barrier to entry. A used machine from a big-box store and a Facebook page is all it takes, which is why Kansas City sees a wave of new “companies” every spring — and a wave of damaged siding, streaked roofs, and etched concrete every summer. The difference between a professional exterior cleaning company and a guy with a pressure washer is not the equipment. It is insurance, chemistry, process, and accountability.

The 7 checks that separate pros from pretenders

1. Real insurance — and proof on paper

Ask for a certificate of insurance (COI) with general liability and workers’ compensation. In Missouri, if an uninsured worker is hurt on your property, the claim can land on your homeowner’s policy. A professional outfit can email you a current COI the same day you ask. KC Splash carries $3M in coverage and provides same-day COIs on request.

2. Soft washing for siding and roofs

High pressure destroys vinyl siding, forces water behind Hardie board, and voids shingle warranties. The professional standard is soft washing — low pressure with detergents that kill the algae rather than blasting at it. If a company quotes your house or roof and never mentions soft washing, keep looking.

3. A guarantee in writing

Spot-free today is easy; the question is next year. Ask how long the results are warrantied and get it in writing. KC Splash puts a 2-year house wash guarantee and a 3-year roof cleaning guarantee on paper — if algae comes back early, we re-clean free. See our written guarantees.

4. A review history you can read

Not the star rating — the reviews themselves. Look for named neighborhoods, specific services, and how the company answers criticism. A company with 300+ detailed five-star reviews earned them one job at a time. Read ours here.

5. Transparent pricing

Most companies hide pricing until they are standing in your driveway. There is a reason: it lets them price by ZIP code and by how nice your car is. Published rates keep everyone honest — our full price list is public: house washing runs $0.20/ft², roof cleaning $0.30/ft², driveways $0.25/ft², with a $300 service minimum. Details in our Kansas City pricing guide.

6. Real photos of real local work

Stock photos are a tell. Ask to see before-and-after photos of jobs in your area — or better, case studies with addresses and details you can verify. Our gallery and case studies are all Kansas City metro properties.

7. Communication that respects your day

Professionals give you an arrival window, confirm the day before, and text when they are on the way. If getting a quote takes three phone calls, imagine scheduling the work.

Red flags that predict a bad job

• Cash-only pricing, or a price that drops the moment you hesitate
• No physical address or service area listed anywhere
• “We pressure wash everything” — one pressure for roofs, siding, and concrete means damage to at least two of them
• No mention of what chemicals are used, or “just water” claims for algae-covered surfaces
• Pressure to sign today for a “today-only” discount

Why the cheapest bid usually costs the most

A lowball bid has to cut something: insurance, legal chemical disposal, trained crew, or time on your property. The results show up later — algae back in three months, stripes in the siding, a roof warranty voided by pressure. Paying twice is the expensive way to buy a house wash. The right question is not “who is cheapest” but “who will still stand behind this in two years.”

What it should cost in Kansas City

For a typical KC-metro home: house washing at $0.20/ft² of home square footage, roof cleaning at $0.30/ft², gutter cleaning at $0.10/ft², driveways and patios at $0.25/ft². A 1,500 square foot house is $300 and a 5,000 square foot house is $1,000. Full numbers and examples: what pressure washing costs in Kansas City.
