Deck Sealing & Waterproofing Mundelein, IL

Deck sealing for Mundelein homes

Most of our deck sealing calls in Mundelein come from homes with older bungalows near downtown plus 1980s-to-2000s subdivisions. We see a lot of privacy fences between close lots, and the work is planned around it.

With Diamond Lake close by, decks and fences here hold moisture longer in the mornings. We schedule the wash early in the week so there is time to dry before stain goes on.

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 Mundelein

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.
