Balcony Waterproofing in Los Angeles & Orange County
A code-compliant balcony waterproofing system that stops leaks, dry rot, and inspection-flagged damage, most projects backed by our 8-year warranty.
Takes about 30 seconds. No obligation, no pressure.
Keep Your Balcony and the Structure Beneath It Protected
Balconies sit directly over living space and absorb constant sun, rain, and foot traffic. Once the waterproof membrane breaks down, moisture reaches the framing underneath, and that is where dry rot, corroded connectors, and the kind of structural damage California inspectors flag under SB-721 and SB-326 start to show up.
Balcony Works installs code-compliant balcony waterproofing that seals the walking surface, safeguards the structure below, and holds up to daily use, most projects backed by our 8-year warranty.

Yes. We waterproof and repair exterior elevated elements to current code requirements and can work directly from your inspection report to bring balconies into compliance.
How long does a waterproofing job hold up?
A properly installed system typically holds up for years. Most of our projects come with an 8-year workmanship warranty, and regular upkeep can stretch that lifespan even further.
What should I expect to pay for waterproofing in the LA area?
Pricing depends on the size of the surface, its current condition, and which coating system fits the job. After a free on-site inspection we give you a clear, itemized quote, no pressure and no obligation.
