Waterproofing & Leak Detection
Life Deck and full membrane systems
Liquid-applied waterproofing membranes for decks, foundations, walls, and windows — including Life Deck systems. Protect against the wet Northern California winter.
Our crews bring decades of hands-on experience to every waterproofing project. We work clean, communicate clearly, and deliver finishes that look right and hold up to Bay Area weather.
Every project starts with a careful site walk and a written estimate. We assess substrate condition, surrounding finishes, and any waterproofing or structural prep before the work begins. We handle the entire stack in-house: lath, mesh, scratch coat, brown coat, finish — and any specialty coatings called out by the architect or homeowner.
