Deck Sealing & Waterproofing Waukegan, IL

Deck sealing for Waukegan homes

Deck sealing in Waukegan starts with knowing the housing: the county's largest city, with a wide range of housing from historic to new. We see a lot of older decks and porches across the city, and the work is planned around it.

Being near Lake Michigan matters too. Wood close to water sees more humidity, more morning dew and, on open water, more reflected sun. We allow extra drying time and lean toward stains with stronger UV blockers on the exposed sides.

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 Waukegan

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.
