Bring a gray, mildewed deck in Warrenville back to clean wood, with stain that soaks in and holds. We clean it, let it dry properly and stain only when the wood is ready.
Stain protects exterior wood, and it only works on wood that is clean, sound and dry. We wash off mildew, dirt and graying, then brighten the boards so they open up to take stain. Coatings that have peeled or worn unevenly get stripped or sanded back, and soft boards get replaced. The same order applies whether it is a deck, a fence, a pergola, wood siding, trim or a front door.
We work in Warrenville every week, coming in on I-88, Route 59, Butterfield Road and Winfield Road. Where a yard sits under big trees or close to the West Branch of the DuPage River, a deck can stay damp longer and grow mildew in the shade. That changes how we run the job: the cleaning goes deeper, and the wood gets extra drying time before any stain goes on. Stain over damp wood peels, so we would rather wait a day than redo your deck next year.

Shaded boards get a cleaner that kills mildew at the root, then a rinse, so the stain does not trap growth underneath.
A brightener after cleaning brings back the wood's color and opens the grain so the stain absorbs evenly.
We check the boards before staining and wait when they are still wet, because stain over damp wood lets go.
Packed leaves and dirt come out from between the deck boards so water drains and the board edges dry out.
Boards that have gone soft or split get swapped for new wood before the stain, not coated over.
Each coat gets back-brushed into the boards, rails and stair treads so it soaks in instead of sitting on top.
First we look at the wood with you, see how wet and worn it is and write an estimate that spells out the cleaning, repairs, stain type and coats. If a board turns out to be rotted underneath once we start, we stop, show you and put the repair price in writing for your OK. Cleaning day and stain day are usually separate, with drying time between, and the forecast settles the exact dates. At the end we walk the deck with you and fix anything you flag.
