Deck Sealing & Waterproofing North Chicago, IL

Deck sealing for North Chicago homes

North Chicago has older neighborhoods near Naval Station Great Lakes and the lakefront, and that shapes how we approach deck sealing here. We see a lot of small decks and porches on older homes, and the work is planned around it.

North Chicago 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.

We seal decks across Lake County with penetrating water repellents that soak into the wood rather than forming a surface film. A film is what cracks and peels. Applied to clean, dry wood, a good sealer beads water for a season or two and buys time before the deck needs a full stain.

How the job goes in North Chicago

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.
