Deck Sealing & Waterproofing Highland Park, IL

Deck sealing for Highland Park homes

Highland Park has North Shore homes on ravine and lakefront lots with old-growth trees, and that shapes how we approach deck sealing here. In practice that means estate fences and pergolas.

Highland Park sits on Lake Michigan, and waterfront wood weathers faster on the water-facing side than the house side. We check both and often give the exposed side a second coat.

Ask a Lake County homeowner when their deck was last sealed and the honest answer is usually never. Water gets into the end grain at the board ends, the screw holes and the ledger board against the house, and that is where rot starts. A sealer is cheap insurance. It is also the one step people think they can skip on a hardwood deck, when hardwood is exactly what a UV-blocking penetrating oil is made for.

How the job goes in Highland Park

1. Moisture checkThe deck must read under about 15% on a moisture meter. Sealing wet wood traps the water in and the sealer will not bond.
2. Clean and brightenEven a deck that looks clean has surface oxidation. A percarbonate wash and brightener open the grain so the sealer penetrates.
3. Mask and protectSiding, doors, planters and the patio below are covered. Sealers are thin and travel.
4. Apply thin, even coatsPad or sprayer with a back-brush. The wood takes what it can absorb and the rest is wiped off so it does not leave a sticky film.
