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.
Will waterproofing change how my property looks?
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.
How much does waterproofing cost?
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.
How long does waterproofing last?
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.
How much disruption should I expect during the waterproofing process?
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.
What should I look for when hiring a waterproofing contractor?
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.
