What we do

Waterproofing built for elevated exterior structures

We don't do everything โ€” we do balconies, decks and stairs, and we do them right. Specialization is why our work holds up.

01 / BALCONY

Balcony waterproofing

Membrane and coating systems that stop water intrusion, protect the framing below, and extend the life of your balconies.

02 / DECK

Deck waterproofing & coating

Durable, slip-resistant waterproof deck coatings for walking surfaces โ€” sealed at every seam, drain and transition.

03 / STAIRS

Stairs & stairway waterproofing

Exterior stairs and landings sealed and coated to keep water out of the structure and prevent costly deterioration.

California law

SB 721 & SB 326 deadlines are here

California now requires inspection and repair of elevated exterior elements โ€” balconies, decks, stairways and walkways. If yours failed inspection or needs to be brought up to code, we handle the waterproofing and repairs that get you compliant.
