Under That Gray Layer, Your Deck Still Remembers Its Color
Weathered decks aren't dead — they're dormant. Our wood-safe cleaning process strips away the gray oxidation, algae, and embedded grime to reveal the surface you built, without the gouging and furring that high pressure leaves in the wood.
The Most Abused Surface in Backyard Michigan
Your deck takes everything this climate throws: UV that oxidizes wood fibers gray, humidity that feeds algae in every board gap, snow that sits for months, and a summer of foot traffic grinding it all in. By year three or four, most decks wear a uniform coat of gray-green that owners assume is just "how decks age." Cleaning starts at $199 and is priced at $1 to $2 per square foot, and it doubles as the prep step for any stain or sealer that follows.
That gray-green layer is not age, and it comes off with the right method. High pressure on softwood decking gouges wake-like trenches and "furs" the grain into splinter-raising fuzz, permanent damage we see often on decks washed at high pressure. Our process inverts the formula: specialized wood-cleaning solutions do the heavy lifting, breaking down oxidation and killing organic growth, followed by careful low-pressure rinsing that the wood barely notices.
Composite decking gets its own protocol — manufacturers like Trex specify gentle washing to keep warranties intact, and embedded mold in composite grain needs solution-based removal, not blasting. Either way, your deck comes back clean, structurally unharmed, and ready for the season.

Cleaning Is Step One of Whatever Comes Next
Planning to stain or seal? Professional cleaning isn't optional prep — it's the foundation. Stain applied over gray oxidation and algae peels within a year, which is why refinishing over an uncleaned deck so often fails early. A properly cleaned and dried deck accepts stain evenly and holds it for years.
Not refinishing? Annual cleaning alone considerably extends deck life by removing the moisture-holding growth that accelerates rot in every board gap and fastener hole. Either way, the clean comes first — and ours is the clean the stain manufacturers had in mind.

Deck Cleaning FAQs
Will pressure washing splinter my deck?
High pressure held close to the boards will. Furred, splintered grain from concentrated pressure on soft wood is the most common deck damage we see. Our method uses cleaning solutions to do the work and only gentle rinsing pressure on the wood itself, so the grain stays smooth and intact. The solution does the cleaning, so the rinse never needs enough force to open the grain.
Can you clean composite decking like Trex?
Yes, with composite-specific protocols. Composite isn't maintenance-free, since mold grows in its textured grain like anything else. It also requires gentle washing to stay within manufacturer warranty terms. We clean it the way the manufacturers specify.
How soon after cleaning can I stain my deck?
Typically two to three dry days, depending on weather and wood saturation. We'll give you an exact window at the job, and if you'd like recommendations on stain products for Michigan conditions, just ask — we've seen what holds up and what doesn't across hundreds of local decks.
How often should a deck be cleaned?
Annually, ideally in late spring — it removes the winter's accumulation before summer entertaining season and keeps organic growth from ever establishing deep roots. Decks under heavy tree cover or with northern exposure may benefit from a fall touch-up too.
