Our Core Waterproofing Services in Los Angeles

Your LA property deserves protection that doesn’t cut corners. We combine skill, science, and the highest-grade materials to create results you can trust.

Deck Waterproofing

Life happens on your deck—family dinners, parties, or just relaxing after a long day. Our deck coating solutions are built to handle it all, from everyday wear to LA’s unpredictable weather. Durable, seamless, and good-looking? Absolutely.

Common Area Waterproofing

Shared spaces like courtyards, patios, and lobbies see a lot of activity, which means water damage can creep in before you know it. We make sure these high-traffic areas stay dry and solid so they’re always ready for daily use.

Stair Waterproofing

Stairs take a beating, and water infiltration doesn’t make it easier. Our stair waterproofing service keeps these high-traffic areas safe, sturdy, and ready for years of use.

Walkway Waterproofing

Walkways are the first to show wear and tear, especially with constant foot traffic and unpredictable weather. Our waterproofing solutions keep them strong, smooth, and safe against cracks, puddles, and slippery spots.

Rooftop Deck Waterproofing

Your rooftop should be a retreat, not a source of stress. We protect your view and your peace of mind with advanced waterproofing that locks out leaks and keeps your structure strong.

Apartment Waterproofing

Apartments are made up of a lot of moving parts—balconies, stairs, tiled surfaces, and more. We create waterproofing plans that make sense for your building, protect the property, and keep tenants happy without causing unnecessary disruption.

Under-Tile Waterproofing Systems

Water has a way of seeping under tiles, but our under-tile systems are engineered to create a strong barrier. Our expert installation process helps protect against the potential for hidden damage.

Condo Waterproofing

Condos come with their own set of challenges, from shared spaces to private units. Whether it’s rooftop decks, walkways, or common areas, we make sure every inch is properly waterproofed so leaks don’t spread, and repairs stay off your to-do list.

Sheet Metal Flashing

Every little detail matters, especially where water’s involved. Our custom sheet metal flashing seals the deal—literally. It’s the added layer of protection your property needs to stay in top shape.

Townhouse Waterproofing

Life happens on your deck—family dinners, parties, or just relaxing after a long day. Our deck coating solutions are built to handle it all, from everyday wear to LA’s unpredictable weather. Durable, seamless, and good-looking? Absolutely.

Got Questions?
Let’s Clear Them Up.

Do I really need waterproofing, or can I just patch up leaks as they happen?

Waterproofing is about PREVENTING leaks altogether. Patching is a quick fix that often leads to bigger (and more expensive) problems over time, like structural damage or mold growth. In California, laws like SB 326 and SB 721 mandate inspections and maintenance of decks, balconies, and other elevated structures to ensure they’re safe and sound. 

A proper waterproofing system keeps you compliant, prevents hidden issues, and protects your property for the long haul.

Not at all! If anything, it can enhance the appearance. Modern waterproofing techniques often include finishes that improve durability and aesthetics. For example, our deck coatings protect against damage while keeping surfaces seamless and polished.

Costs vary depending on the size of the residential and commercial waterproofing project, the materials used, and the complexity of the overall job. During our inspection, we provide a clear estimate tailored to your property’s needs.

It depends on the material and the quality of the work. A professionally installed system, just like what we do at Angel City Development, can last. Regular maintenance helps extend its lifespan even further.

We aim to minimize disruption as much as possible. The scope of the work, like whether it’s a single deck or an entire rooftop, will largely determine the time required, but we work hard to communicate the timeline upfront and keep you informed along the way.

Experience, certifications, and customer reviews matter. Make sure the company is licensed, bonded, and insured. Look for contractors who offer customized solutions, guarantee their work, and communicate openly about the process. 
These key standards are the reason Angel City Development is a waterproofing company Los Angeles residents and businesses trust for lasting protection and a commitment to getting it right the first time.
