Waterproofing for occupied properties

Commercial, HOA & Multifamily Waterproofing in Los Angeles & Orange County

Organized waterproofing and repair programs for HOA communities, apartment buildings and commercial properties throughout Los Angeles and Orange County—from one failed area to multi-building scopes.

Experienced waterproofing since 1985

HOA, apartment & commercial waterproofing repairs

Leaking balconies, deteriorated common-area walkways and worn pedestrian coatings can affect several residents or businesses at once. We inspect the affected decks, stairs, landings and planters by building and location, then distinguish areas needing maintenance from those needing removal and reconstruction. We review drainage, failed coatings, flashing, thresholds and visible substrate damage so the proposal identifies the work at each location.

The repair scope can include failed-system removal, damaged plywood and framing repairs, flashing and drain work, and installation of a suitable waterproof walking surface. Existing SB 326 or SB 721 reports can guide the field review, but listed findings and quantities are verified on site. Boards and managers receive location-based scope, pricing, exclusions, access requirements and a phased schedule. Concealed damage is documented after opening, with additional work confirmed before proceeding; resident closures and cure times are planned around occupied areas.

Specified for the existing assembly

Waterproofing systems we install

We do not force one product onto every deck. The appropriate system depends on the substrate, existing assembly, exposure, expected traffic and project requirements.

01 · Life Specialty Coatings

Walking-Deck Systems

Plywood and concrete waterproofing options considered by substrate, exposure and repair condition for balconies, corridors, walkways and stairs across occupied properties.

02 · Tremco

Vulkem Pedestrian Systems

Traffic-coating systems considered for compatible concrete and other approved assemblies where durability, phasing and return-to-service planning are important.

03 · Westcoat

ALX & MACoat Systems

Waterproof walking-deck systems selected for compatible HOA, apartment and commercial deck assemblies according to project-specific conditions.

04 · Multicoat

Multi-Deck Systems

Above-grade waterproofing options for compatible wood and concrete areas within phased repair and maintenance programs.

Final product selection and specifications are confirmed after the property and existing deck assembly are evaluated.

Common applications

Projects we can evaluate

The final recommendation depends on site conditions, access, the existing assembly and what is uncovered during approved preparation or demolition.

Questions customers ask before starting

Commercial, HOA & Multifamily Waterproofing FAQs

These answers explain the decisions that usually affect scope, scheduling and system selection. The final recommendation is based on the conditions at your property.

Ask about your project
Can you work from an existing SB 326 or SB 721 inspection report?

Yes. You can send the report for an initial review, and the listed areas can then be verified at the property before a repair proposal is prepared. The inspection identifies findings; the site review helps translate them into locations, quantities, access needs and a practical repair scope.

Can a large HOA or apartment project be completed in phases?

Yes. Phasing can be organized by building, elevation, unit group or access area. The sequence depends on urgency, resident circulation, cure periods, budget priorities and the relationship between adjacent waterproofing details.

What should a commercial or HOA waterproofing proposal show?

A decision-ready proposal should clearly identify locations, quantities, preparation, repairs, waterproofing work, finishes, exclusions, assumptions and access responsibilities. Alternate or deferred items should be separated so boards and managers can compare options accurately.

Can residents or businesses remain on the property during repairs?

Often they can remain elsewhere on the property, but active work areas need controlled access and temporary closures. Scheduling is coordinated around safe circulation, noise, preparation, installation and the required cure period for the selected system.
