New paint and stain only last as long as the surface under them. Chalk, mildew, pollen and loose film on a Washington Township house will not disappear under a fresh coat. They will be buried for a season and then show up as peeling or staining. Washington Township Painting is a referral service that connects homeowners with independent local contractors for power washing and the surface prep that should come before exterior painting or deck staining. We do not wash or scrape houses ourselves.
Why Washing Comes First
Michigan siding collects more than dust. North and shaded walls grow mildew. South and west walls chalk as the old binder breaks down in the sun. Gutters overflow and leave dirty streaks. Spring pollen sticks to any film that is still a little tacky. If a crew rolls over that, the new coating is bonding to contamination, not to sound paint or bare wood.
Power washing, used at a pressure and distance that will not gouge wood or drive water behind laps, is often the fastest way to remove that layer. It is not the entire prep. Failed paint still has to be scraped and sanded. Bare wood still has to be primed. Open joints still have to be caulked. Think of washing as the step that lets a contractor see what is actually left on the wall.
What Should Be Washed, and What Needs Care
Painted wood, fiber-cement, and many previously coated surfaces can usually be washed as part of an exterior paint job. Decks and fences are often cleaned with a washer or a deck cleaner, then allowed to dry thoroughly before stain; see deck and fence staining. Vinyl siding is sometimes washed for appearance even when it will not be painted. Brick and bare wood can be damaged by a narrow, high-pressure tip held too close. A contractor should choose pressure, tip and distance for the material, not treat every elevation the same.
Windows, outdoor outlets, dryer vents, light fixtures and landscaping need protection. Irrigation should be off so you are not washing a wet wall. Soft soils along a foundation can be rutted by a heavy hose, especially in a wet Macomb County spring.
Drying Time Before Paint or Stain
This is the step homeowners underestimate. A wall that looks dry in the afternoon sun can still hold water in the laps or at the lower courses. Stain applied to a damp deck will not penetrate well and may peel or go milky. Paint applied over damp siding can blister. After a wash in Washington Township, Romeo or Shelby Township, the contractor should allow drying time that matches the weather, not the calendar they hoped for. A stretch of humid nights or a surprise shower can add a day.
If you are scheduling exterior house painting in the same project, put both on the quote request so washing, drying, scraping and coating can be sequenced in one window of fair weather. Our guide to the best time of year to paint exteriors in Michigan explains why temperature and dew matter after the wash as much as during the coating.
Washing Alone Versus a Full Paint Prep
Some homeowners only want the siding cleaned. That can be a standalone request. Others want washing as the first day of a repaint. Those are different scopes. A clean-only visit will not include scraping, priming or caulking. A full exterior paint scope should say how the wash will be done, how failed film will be removed, and what gets primed. If a bid says "prep and paint" with no detail, ask for the list.
What to Mention on the Form
Note the siding type if you know it, any peeling or bare wood, mildew on shaded walls, and whether you also want the deck, fence or driveway approaches cleaned. Photos help. If the house was built before 1978 and a later step will include aggressive sanding of painted surfaces, mention the age of the home so the contractor can consider lead-safe work practices.
Call the number at the top of the page or request a quote. A local pro will tell you whether washing alone is enough or whether the surfaces need a fuller prep before paint. Using this referral service is free, and you are not obligated to hire anyone.
