Balcony and Walkway Work in One of the Densest Cities in LA County

Cudahy packs 5,854 housing units into roughly a square mile, which works out to about 4,977 units per square mile. That density is almost entirely apartment buildings, and apartment buildings mean shared walkways, exterior stairs and stacked balconies. When the coating on one of those fails, the water does not stay put. It finds the unit below, then the framing, then the stairs everyone uses to get home.

We repair and recoat those surfaces so the building passes inspection and stays passed. That means decks and balconies that drain instead of ponding, stair treads that are not spongy underfoot, and a waterproof layer that is actually continuous where it meets a wall or a post.

Permits & Inspections

Pulling a Permit in Cudahy

Cudahy runs its own Building and Safety Department, which enforces the building, plumbing, electrical and mechanical codes and provides the inspection services. The city also publishes an Exterior Elevated Elements inspection certification form covering SB 721 and SB 326, which require inspection and certification of weather exposed elements more than six feet above the grade below, on buildings with three or more dwelling units. If your inspector has handed you a report, we can price the repairs off it and pull the permit to get the work signed off.

FAQ

Waterproofing in Cudahy: Your Questions

My Cudahy inspection report lists balcony repairs. Can you work from it?

Yes. Bring us the report and we will scope the repairs directly off the findings, pull the permit through Cudahy Building and Safety, and get the work inspected. The city has its own Exterior Elevated Elements certification form for SB 721 and SB 326, and the finished work needs to hold up to it.

Do you work on apartment buildings in Cudahy?

Most of our Cudahy work is multifamily. Shared walkways, exterior stairs and stacked balconies are the bulk of what fails here, and they are what we rebuild and recoat.

How long does a balcony recoat take?

About a week from start to finish on a typical job. We give you a firm timeline before anything starts, and we stage the work so residents keep a way in and out.

How long does waterproofing last?

A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.

How much does waterproofing cost in Los Angeles?

Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.

How long does the job take?

Most residential decks, balconies, and stairs take about a week from start to finish, depending on prep, repairs, and weather. We give you a firm timeline before work begins.
