Shaded decks and fences get the mildew scrubbed out and a stain that soaks into clean wood, so the color looks right. We cover Lisle, from the backyard deck to the pergola.
We cover Lisle for decks, fences, pergolas, wood siding and trim, front doors and interior wood. Each job follows the same order: clean and brighten, strip or sand failed coatings, replace loose or rotted boards, then stain. We help you choose between transparent, semi-transparent and solid stain, and we tell you what each one does for protection and grain. Interior wood gets sanded between coats and a clear topcoat where it is handled.
We reach Lisle on I-88 and Route 53, and work this DuPage County village from Ogden Avenue and Maple Avenue out toward the Morton Arboretum. If your yard sits under big trees, the deck may stay shaded and damp, and that is where mildew, moss and black spots take hold. Stain over mildew traps it and goes dark and blotchy. We kill and wash out the growth, rinse, clear leaves and needles out of the board gaps so water drains, and let the wood dry fully before we stain.

Black spots and green growth get treated with a cleaner made for it and rinsed out before any stain touches the wood.
Leaves, needles and dirt packed between deck boards come out so water drains and the board edges dry.
A brightener opens the grain after cleaning, and we wait for the wood to dry fully before staining shaded areas.
Boards that stayed wet long enough to soften are cut out and replaced with new lumber.
Posts, beams and rafters get cleaned and stained from ladders, with the deck or patio below covered.
We explain how each stain type holds up and help you pick what suits a shaded or sunny part of the yard.
We walk the yard with you for a free estimate, looking at the shaded spots and the sunny ones. The written scope lists cleaning, repairs, the stain type and the coats. If more rot turns up under the mildew once we clean, we price it in writing and wait for your approval. We book around the days we said and look over the finished wood with you before we pack up.
A text to (815) 585-1750 with a shot of the shaded corner of your deck tells us a lot. After an in-person look, the cleaning, repairs and stain all go into one written scope.
