Mildew and Gray Gone, Boards Left Smooth
Wood deck cleaning Wilmington NC homes need removes mildew, algae and gray weathering from pressure treated pine, cedar and hardwood decks. We use a soft wash and low pressure, then a wood brightener that restores color and balances the wood after cleaning. The deck is stain ready once it dries.
This service is part of our deck and fence cleaning work and our broader Wilmington pressure washing services.
It is for owners who want the deck usable again, sellers prepping a home, and anyone planning to stain this season. Call or send photos and we will map out the visit.
What a Wood Deck Visit Includes
We clean every wood part of the deck, not only the floor. Here is the list.
- Floor boardsCleaned in the direction of the grain, including the gaps where dirt packs in.
- Rails and balustersTop rails collect pollen, and spindles hold green film at the base.
- Stairs and stringersTreads are where the slick spots hurt most, so they get extra attention.
- Skirting and latticeShaded lower panels grow mildew first and get washed with the rest.
- Brightener and stain prepA brightener and a drying window set the wood up for stain.
Why Pine Decks Gray and Grow Mildew Here
Most decks around Wilmington are pressure treated southern yellow pine. That wood grays fast under strong sun and holds moisture through our humid summers.
The area gets about 60 inches of rain a year over roughly 122 rainy days (NWS). Boards under tree cover or near the marsh rarely dry out fully. Pollen, leaf tannin and mildew settle in the grain, and the surface turns dark and slick.
Searching for pressure treated deck cleaning usually means a deck that looks neglected after a couple of seasons. It is common, and it is fixable.
How We Clean a Wood Deck Step by Step
Brightening a deck takes patience more than muscle. The sequence below is what we follow on a typical job.
- Clear and sweepFurniture comes off, leaves and grit get swept away.
- Wet the plantsLandscaping beside the deck gets soaked before any cleaner touches the boards.
- Apply deck cleanerA mild mix goes on and sits long enough to loosen the green and black film.
- Rinse with the grainA wide tip and gentle water carry the dirt off without lifting fibers.
- BrightenDeck brightening Wilmington style means a brightener that lightens gray and evens the tone, followed by a second rinse.
- Dry timeThe deck rests, and we take after photos from the same spots as the before shots.
Pine, Cedar, Ipe and Painted Porch Floors
Every wood reacts differently, so the method changes with the board. Here is how we handle the common ones.
| Wood | Common Problem | Our Approach |
|---|---|---|
| Pressure treated pine | Gray top layer, mildew, algae | Soft wash, brightener, dry time |
| Cedar | Tannin streaks, dark spots | Mild cleaner, gentle rinse, extra care |
| Ipe | Dirt in tight grain, pollen | Low pressure, soft brush where needed |
| Painted porch floors | Mildew, peeling old paint | Gentle wash, no harsh stripping |
Cedar deck cleaning calls us for tannin stains that look like brown bleeding along the boards. A mild cleaner and patience lift most of it without damage.
Older homes in Pine Valley and Historic Downtown often have painted front porches. Porch floor cleaning Wilmington owners ask about is a softer job with careful pressure, because old paint peels under force.
Gray Deck Restore Without Sanding
Bringing gray boards back starts with cleaning and brightening, not sanding. The gray is a thin layer of sun damaged wood on the top of each board. Cleaning lifts that layer and the brightener evens out what is left.
Very old wood may still look weathered in spots, and we tell you that when we see it. Failing old stain gets noted before we start so you know what to expect.
What Wood Deck Cleaning Cost Wilmington NC Owners See
Prices are a range that depends on the deck. Brackets mark ranges we confirm on your quote.
| Deck Size | Typical Range | What Moves It |
|---|---|---|
| Small deck or porch | $150 to $250 | Stairs, rail count, access |
| Average deck | $200 to $350 | Gray level, board gaps, height |
| Large or two level deck | $300 to $400 | Square footage, second level |
Brightener and stain prep can add to the total. The number on your quote also moves with how heavy the mildew is and how close the deck sits to the ground. We give the range first and confirm it on site.
Hiring a Crew for Wood Deck Work
Wood Deck Cleaning is available throughout Wilmington and nearby communities. We give both.
If you are comparing a wood deck cleaning company Wilmington NC homeowners recommend, ask these questions. Is the crew insured? Do they use low pressure? Can they show before and after photos? Our answer to each is yes.
When comparing wood deck cleaning providers, focus on surface-safe methods, clear pricing and documented results. We have cleaned pine, cedar and treated lumber around town, so tell us what you have and we will match the method.
Clean Deck Before Staining
Prep is the single biggest factor in how long a stain lasts. Stain over mildew traps it under the surface and the finish peels early.
Plan on a dry day or two after cleaning so the wood can take stain evenly. If you have fuzz from a past wash, light sanding smooths it first.
Wood Deck Results Around Wilmington
We have brought gray, mossy and slick wood decks back to life across Wilmington and the coastal towns near it. On those projects the results ran like this:
| Wood | What changed |
|---|---|
| Gray pine floor | Faded boards turned warm and even after the brightener |
| Rails and steps | Green film and grime gone, so hands and feet are safe |
| Sun faded cedar | Natural color back, with the grain left smooth |
Protecting Boards, Plants and Siding
We use low pressure with the grain, because force tears up soft pine. Siding and windows beside the deck get a gentle rinse so cleaner does not dry on them.
Shrubs and flower beds get soaked first and rinsed after. We keep pets and kids away until everything is rinsed and the boards are damp but not slick.
Other Deck Services Worth a Look
If your yard has a composite deck as well, or a fence that matches the gray boards, ask about those at the same visit. Combining them saves a trip.

Wood Deck Questions Answered
Why is my wood fuzzy after pressure washing?
Too much pressure tears up the wood fibers. A soft wash with low pressure avoids that. Light fuzz can be sanded before staining.
How long after cleaning can I stain my deck?
Usually one to two dry days. Wood needs to dry out before stain will soak in evenly.
Can you bring back the color of a gray deck?
Mostly, yes. Cleaning plus a brightener removes the gray top layer and evens the color. Very old wood may still look weathered in spots.
