Done right the first time
We work across Los Angeles County for homeowners who want the job done right the first time: decks and balconies over living space, tile and flat roofs, and the waterproofing that ties them together, from hillside homes to multi-level houses with decks stacked over living space.
It’s the same company and the same crews that have kept Orange County homes dry since 1945, with one manufacturer’s system on every job, start to finish.
What we do in Los Angeles
Decks & Balconies
Waterproofing, repair and recoats for decks and balconies, including the ones over living space.
Roofing
Tile, shingle and flat roof repair, inspections, coatings and replacements.
Commercial
Roof repair and coatings for commercial buildings, with the same honest assessment we bring to homes.
Hillside and multi-level homes
Many LA homes are built on slopes, with decks hanging off the back and balconies stacked over living space. Water has a lot of places to go on a house like that, and gravity takes it straight into the framing.
We trace the water from where it shows up back to where it gets in, fix the cause, then install a complete system so the deck and the house below stay dry.
We don’t build on bad bones.We’d rather lose a bid than put new work on top of an old problem.
