Deck Waterproofing in Los Angeles & Orange County
A durable, code-compliant deck coating system that stops leaks, dry rot, and structural damage before they spread, most projects backed by our 8-year warranty.
Takes about 30 seconds. No obligation, no pressure.
Protect Your Deck From the Ground Up
Decks take a beating from sun, rain, and daily foot traffic, and once the waterproof layer gives out, water finds its way into the structure below. Left unaddressed, that moisture turns into dry rot, corroded framing, and repair bills far larger than the original coating job.
Balcony Works installs proven deck waterproofing systems that seal the walking surface, direct water to proper drainage, and hold up to everyday use. Whether it is a walking deck, roof deck, or balcony, we match the system to your surface and stand behind most projects with an 8-year warranty.
Signs Your Deck Needs Attention
- Cracking, blistering, or peeling in the current coating
- Soft, spongy, or discolored areas underfoot
- Water stains or active leaks on the ceiling or wall below
- Water that pools instead of draining after rain
- Exposed wood, rust, or a coating past 8–10 years old

Common Deck Waterproofing Questions
How can I tell if my deck coating has failed?
Cracking, peeling, soft spots, or leaks showing up underneath the deck are all signs the waterproof layer is no longer doing its job. A free on-site inspection will confirm what is going on and what it will take to fix it.
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.
How many days will the project take?
Most residential decks, balconies, and stairs wrap up in one to three days depending on prep work and weather. You will get a firm timeline before the crew starts.
Can you handle HOA and commercial jobs?
Yes. We take on residential, HOA, and commercial waterproofing throughout Los Angeles and Orange County, and we are licensed (1045438) and insured for projects of any size.
