Liquid-applied waterproofing membranes for decks, foundations, walls, and windows — including Life Deck systems. Protect against the wet Northern California winter.
We waterproof the places water usually gets into a building: decks and balconies, window and door openings, foundations and the base of walls. Systems include liquid-applied membranes and Life Deck coatings for walkable decks.
When a wall is being re-stuccoed, windows and other openings can be waterproofed in the same job. When a leak has already caused rot behind the stucco, our crews repair that too (see Dryrot Repair).
