What makes waterproofing services different in Holmby Hills
Holmby Hills is part of LA's Platinum Triangle — the smallest and most exclusive of the three corners alongside Beverly Hills and Bel Air. Lots are large; homes are old; budgets and timelines reflect both. Mediterranean and English-manor estates dominate, often with original 1920s and 1930s plumbing and electrical that need full updates during any serious remodel. We approach Holmby Hills with the same precision the architecture deserves.
Hillside parcels in Holmby Hills carry their own engineering load. Drainage, retaining-wall design, caissons where pools or major additions are part of the scope, and fire-zone defensible-space requirements all shape how a waterproofing services project gets sequenced. We coordinate hillside engineering at the design phase, not at construction.
Most Holmby Hills homes were built before 1980. That means galvanized supply lines, undersized electrical panels, original gas runs, and rough-in plumbing that hasn't been touched in decades. Once walls open during a waterproofing services project, we expect to bring the underlying systems to current code — not as a surprise, as a plan.
Common architecture in Holmby Hills: Mediterranean Estate, English Manor, Spanish Colonial Revival. We design westside renovations to honor what's already there while bringing systems and finishes up to current code and current standards.

Waterproofing Services in Holmby Hills — Frequently Asked Questions
Signs include musty smells, visible mold, water stains on ceilings or walls, efflorescence on foundation walls (white mineral deposits), standing water after rain, and peeling paint in below-grade areas. If you notice any of these, we recommend an assessment.
Exterior foundation waterproofing involves excavating along the foundation wall, applying a waterproof membrane, installing drainage board, and placing a French drain at the footing to direct water away from the structure. For interior solutions, we install drainage channels and sump pumps.
Traffic-rated deck coatings typically last 8–15 years depending on foot traffic, UV exposure, and maintenance. We recommend an inspection every 3–5 years and recoating when the surface shows signs of wear or cracking.
Yes — always. Shower waterproofing is a non-negotiable standard on every bathroom remodel we do. We use Schluter Kerdi membrane systems and flood-test every shower before tiling begins.
