How to Choose a Pressure Washing Company in Michigan: What to Ask Before You Book

Michigan's pressure washing season runs from the last frost in April to the first hard freeze in November, and the best companies are booked two to three weeks out by Memorial Day. That short window is why so many homeowners in Grand Rapids, Ann Arbor, and the Detroit suburbs end up hiring whoever answers the phone first. It is also why the same complaints show up every summer: stripped vinyl siding, etched concrete, dead shrubs, and a crew that never came back to fix any of it.

Choosing well is mostly a matter of asking six or seven questions before the truck arrives. This guide covers what a competent Michigan pressure washing company should be able to tell you about pressure, chemicals, insurance, and pricing, what the work should cost in the state right now, and the warning signs that predict a bad job.

Soft Washing Versus Pressure Washing

The first question to ask is whether the company soft washes siding and roofs. Soft washing uses low pressure, under 500 PSI, and a cleaning solution that kills algae and mildew, while pressure washing uses 2,000 to 4,000 PSI and water alone or with a mild detergent. They are different tools for different surfaces.

Vinyl siding, which covers the majority of homes built since 1980 in Michigan subdivisions from Macomb County to Kentwood, should be soft washed. High pressure forces water behind the panels, strips the finish, and leaves streaks. Asphalt shingle roofs should only ever be soft washed, because pressure removes the granules that protect the roof.

Concrete driveways, brick pavers, and stone patios can take real pressure, and that is where a surface cleaner attachment does the work. Wood decks fall in between and need low pressure with the grain.

A company that says it pressure washes everything at the same setting is telling you it will damage something. The right answer to "how do you clean siding" is soft wash, and the right answer to "how do you clean concrete" is a surface cleaner at 3,000 PSI or so.

What the Work Should Cost in Michigan

A full house wash on a 2,000 square foot two-story vinyl home runs $300 to $550 in the Detroit suburbs, Ann Arbor, and Grand Rapids. Ranches are cheaper at $250 to $400. Larger homes in Bloomfield Hills, Northville, or Ada with brick and stone accents run $500 to $900.

Driveway cleaning runs $0.15 to $0.35 per square foot, so a standard two-car driveway of 600 square feet costs $100 to $200. Adding a sealer roughly doubles it. Patios and walkways are priced the same way.

Deck cleaning runs $1 to $2 per square foot, and staining afterward runs $3 to $6 per square foot. Roof soft washing runs $400 to $900 for a typical home and is the most variable line, because it depends on pitch and how much moss and algae have taken hold. Homes shaded by mature trees in Ann Arbor, East Lansing, and older Grand Rapids neighborhoods have the most roof growth.

Northern Michigan and the Upper Peninsula run 10 to 20 percent lower on labor, but travel fees for cottages outside Traverse City, Petoskey, or Marquette can offset that. Many companies charge $50 to $100 for jobs more than 30 minutes from their base.

Bundled pricing is common. House wash plus driveway plus a small patio often lands at $500 to $800, which is 15 to 25 percent below booking each separately.

Insurance and Licensing in Michigan

Michigan does not require a state license for pressure washing. That means anyone with a rented machine and a truck can advertise, and many do every spring. The protections you have are the company's insurance and its track record.

Ask for a certificate of general liability insurance and confirm the policy is active by calling the agent. Coverage of $1 million is typical for established companies. A pressure washer can blow out a window, strip paint, or knock a gutter loose, and without insurance those repairs are on you.

Ask about workers compensation if the company sends more than one person. A worker who slips off a ladder at your house without coverage can bring a claim against your homeowners policy. Solo operators may be exempt, but they should say so.

Some Michigan municipalities require a business license or a peddler's permit for companies that solicit door to door. That is worth asking about if someone knocks on your door in Livonia or Troy offering a discount because they are "already in the neighborhood."

Chemicals, Landscaping, and Runoff

The second question after pressure is what goes into the cleaning solution. Most soft wash mixes use sodium hypochlorite, which is bleach, diluted to 1 to 3 percent for siding and higher for roofs. It works and it is the industry standard, and it also kills plants if it lands on them at strength.

A careful company wets down shrubs and lawns before and after washing, covers sensitive plantings, and rinses runoff away from garden beds. Ask how they protect landscaping. If the answer is vague, expect brown spots on your hostas in a week.

Michigan's stormwater rules matter for driveways. Runoff that carries degreaser or heavy sediment into a storm drain can draw a fine in cities like Ann Arbor and Grand Rapids that enforce their ordinances. Companies should use biodegradable degreasers and avoid pushing oil-stained runoff to the street.

Ask whether they use a dedicated roof mix with surfactant, which helps the solution cling on a pitched surface. Companies that treat a roof with the same mix they use for siding are usually underpowered for moss.

Michigan-Specific Problems to Ask About

Moss and lichen on north-facing roofs are common across the state because of the shade and humidity, and they are harder to remove than plain algae. Ask whether the company includes a follow-up rinse after the moss dies, which usually takes a few weeks. Some companies come back at no charge.

Spider webs and insect residue on lake homes are heavy on the west side of the state and the Lake St. Clair shore. Companies that work lake properties know to wash eaves and soffits carefully and to expect a longer job.

Irrigation and well water staining shows up on brick and siding in Oakland and Livingston counties where wells are common. Rust stains need an oxalic acid treatment, which most general washers do not carry.

Salt residue on lower siding and garage doors from winter road spray is a spring problem in every Michigan suburb. A good company includes a rinse of the lower three feet in a house wash rather than charging extra.

Reading a Quote and Spotting Warning Signs

A written quote should list each surface, the method, the square footage or a fixed price, and what is excluded. Quotes that say "whole house $250" with no detail leave room for the company to skip the back or charge extra for the second story.

Ask for a start date and an estimated duration. A house wash takes two to four hours, and a full package with driveway and deck takes a day. A company that promises to do everything in an hour is going to use too much pressure to get done.

Warning signs are consistent across the state. A demand for full payment up front, a quote far below everyone else, no physical address on the website, and reviews that mention damage without a response from the company are the main ones. Storm-season door knockers are the other, and they show up in the Detroit suburbs every June.

Compare a few pressure washing companies serving your part of Michigan on those points before booking, and read reviews for how the company handled a problem rather than just how many stars it has.

Frequently Asked Questions

How much does it cost to pressure wash a house in Michigan?

A full soft wash on a typical two-story vinyl home runs $300 to $550 in the Detroit, Ann Arbor, and Grand Rapids areas. Bundling a driveway and patio brings the package to $500 to $800.

Does a pressure washing company need a license in Michigan?

No state license is required. Insurance is the main protection, so ask for a certificate of general liability coverage and confirm it with the agent before the crew arrives.

When is the best time to pressure wash in Michigan?

Late April through May gets ahead of the summer rush and clears winter salt and grime. October is the other good window, before the first freeze, and companies are less busy then.

Will pressure washing damage vinyl siding?

It can if done at high pressure. Vinyl should be soft washed at under 500 PSI with a cleaning solution, and any company that plans to pressure wash siding at 2,000 PSI or more should be crossed off the list.

How often should a Michigan home be washed?

Every one to two years for siding, and every two to four years for roofs, depending on shade. Homes under mature trees in Ann Arbor, Okemos, or East Grand Rapids sit at the shorter end of those ranges.
