Deck Sealing & Waterproofing Gurnee, IL

Deck sealing for Gurnee homes

Gurnee has large 1980s-to-2000s subdivisions with a lot of original decks, and that shapes how we approach deck sealing here. In practice that means cedar fences on the subdivisions east and west of Route 41.

The wooded corridor along the Des Plaines River means a lot of Gurnee yards are shaded for most of the day. Shaded wood stays damp, grows mildew on the north side and needs a thorough chemical clean and brightener before it will take stain evenly.

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 Gurnee

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.
