Harrison, Michigan is lake country — and that means decks get serious use from the first warm day in May through the last bonfire weekend in October. They also get serious punishment. Lake humidity, spring rains, harsh UV exposure through the summer, and the weight of Michigan winters leave wood decks gray, weathered, and covered in algae. Composite decks fare better structurally, but still accumulate surface algae, mildew, and tannin staining that makes them look worn and neglected.
Michigan Power Washing Pros restores Harrison-area decks to their original appearance — and beyond. Our professional deck cleaning process removes years of accumulated algae, mold, mildew, tannin staining, and weathered gray, revealing the clean wood grain or composite surface beneath. The result is a deck that looks like it was just installed — and a surface that’s properly prepared for staining or sealing if you want to protect it going forward.
Whether you’re getting ready for lake season, prepping to sell a Harrison property, or just tired of looking at a deck that used to be beautiful, we deliver results that are immediate and dramatic.

Questions & Answers
About Deck Cleaning
In most cases, yes. Even heavily weathered, gray, algae-covered wood decks can be dramatically restored with professional cleaning. The extent of restoration depends on the wood species, how long the deck has been neglected, and whether there’s any structural damage. We’ll give you an honest assessment before starting.
Yes. Composite decking requires gentler cleaning chemistry and lower water pressure than wood to avoid surface damage. We use composite-specific cleaning solutions and carefully calibrated pressure settings to clean effectively without harming the material or voiding manufacturer warranties.
If you have a wood deck, sealing or staining after professional cleaning significantly extends the life of the wood and slows future weathering and algae regrowth. We can advise on timing — wood decks need to dry fully before stain or sealer is applied, typically 48–72 hours after cleaning in good weather. We don’t apply stain or sealer ourselves, but we prepare the surface perfectly for it.
A standard single-level deck takes 1–2 hours. Larger, multi-level decks or those with pergolas, built-in benches, and stairs take longer. We give you an accurate estimate before your service date.
Professional cleaning will lighten or remove failing, peeling stain and sealer. If your deck has a well-bonded existing finish, cleaning will restore its appearance without stripping it entirely. We’ll let you know what to expect based on your deck’s current condition when we provide your in-person estimate. To get a quick estimate on price range. You can use our online estimator.
