Waterproofing for larger and occupied properties
Managing Waterproofing Across Shared Building Areas
Apartment buildings, condominiums, HOAs, and commercial properties often contain many connected waterproofing details. A leak at one balcony, walkway, planter, wall, or podium transition can affect multiple units and areas below.
The repair scope must consider substrate condition, drainage, traffic, access, finished surfaces, penetrations, and the relationship between repeated details across the property. A consistent approach helps property teams prioritize immediate failures while planning broader maintenance or replacement.
We work with owners, property managers, contractors, and HOA representatives to evaluate the affected areas and define a practical waterproofing scope based on existing conditions.

Residential and commercial experience

Commercial and multi-family waterproofing projects require clear communication about affected areas, access, sequencing, and existing conditions. We help property teams understand whether a localized repair, phased program, recoating, or broader replacement is appropriate.

Common questions
Commercial & Multi-Family Waterproofing FAQs
Do you work with HOAs and property management companies?
Yes. We work with property owners, managers, HOA representatives, contractors, apartment communities, condominiums, and commercial properties to evaluate and address waterproofing conditions.
Can a large property be repaired in phases?
Often, work can be organized by urgency, building area, access, substrate, or system condition. The appropriate phasing depends on how the waterproofing areas connect and whether delaying adjacent work could affect completed repairs.
What commercial surfaces do you waterproof?
We work on balconies, exterior walkways, podium decks, courtyards, roof decks, terraces, planters, retaining walls, below-grade areas, and concrete, plywood, tile, paver, or stone assemblies.
Can you match an existing deck coating?
A compatible system and practical finish are selected after evaluating the existing coating, substrate, texture, color, condition, and remaining service area. Exact matches can vary with age and exposure.
Do you handle recurring balcony and walkway leaks?
Yes. We evaluate repeated failures, drains, cracks, transitions, penetrations, and earlier patching to determine whether targeted repair, phased restoration, or broader replacement is appropriate.
Which areas do you serve?
Our service area includes Santa Monica, Beverly Hills, Malibu, West Hollywood, Marina del Rey, Manhattan Beach, Van Nuys, Woodland Hills, Calabasas, and surrounding Los Angeles communities.
