Waterproofing
Balconies, decks, and below-grade — water always finds the low point. We waterproof everything beneath the roofline, walls and foundations included, so one contractor is accountable for every way water enters your building.
What We Do
Balcony & Deck
Walkable waterproof coating systems for decks, balconies, and stairs.
Below-Grade
Foundation walls, planters, and subterranean spaces that stay dry.
Exterior Walls
Sealing the envelope where wind-driven rain gets in.
Sump Pumps & Drainage
French drains and pumps — water managed, not fought.
Pools & Planters
Containment waterproofing that protects the structure around it.
Roof Tie-Ins
Where waterproofing meets roofing, one contractor owns the seam.
Balcony Inspection Flagged Something?
California's balcony inspection laws — SB326 for condominiums and HOAs, SB721 for apartment buildings — now require repairs of flagged elevated elements within set windows. We repair what the report flagged: waterproofing, flashing, and coating systems on decks, balconies, and walkways. The balcony repair page walks through which law covers your building, what happens after a flagged report, and how the repairs get done.
Waterproofing Questions
Deck coating protects surfaces you walk on above living space — decks, balconies, stairs — with a flexible, walkable membrane. Below-grade waterproofing seals structure that sits against soil — foundation walls, planters, subterranean rooms — where water arrives under pressure and there is no easy second chance once the dirt goes back. They are different systems solving different problems. We install both, which is why one contractor can own every way water enters your building.
We trace the water back from where it shows to where it enters — and those are rarely the same place. Water travels along framing, laps, and fasteners before it appears on a ceiling, so we test the suspect area section by section and confirm the entry point before recommending anything. It is slower than guessing. It is also why the repair holds.
Yes. Planters and pools are containment waterproofing — the structure holds water and soil on purpose, so the membrane's job is to protect everything around it. We waterproof planters, pools, and fountains, and we tie those systems into the building's drainage so water leaves by design.
Yes — coverage is confirmed in writing for each job before work begins. System coverage depends on the membrane or coating being installed, and our workmanship coverage is stated alongside it in your scope, so you know exactly what is covered and for how long before you sign anything.
