Leaking or water-damaged balcony? We find the source, repair the damage, and rebuild a code-compliant, watertight surface.
By the time a balcony leak shows up on the ceiling below, water has been working on the framing for a while. Every rain adds to the dry rot, and what starts as a coating repair can become a structural one if it waits.
Our crews open up the damage, repair the substrate and framing dry rot, and rebuild the balcony with a code-compliant waterproof system, so the leak is gone and the structure is protected, most projects backed by our 8-year warranty.
Notice any of these? Call 818-697-6334 for a free on-site evaluation.
We assess the substrate, drainage, and existing coating to pinpoint the real source of water intrusion, not just the symptom.
We remove failed coatings, repair cracks and dry rot, and rebuild a sound, stable substrate before anything else.
We install the right coating system for your surface, traffic, and exposure, applied to code by experienced crews.
We review the finished work with you and back most projects with our industry-leading 8-year warranty.

“Had a huge issue in the new year with my balcony leaking. Thankfully, even during holidays they came by quickly to quote and had availability pretty quick. There were heavy rains for a while here, so I’m glad we got it situated and under control. Definitely would recommend. Thanks again and happy new year”
“Quick response. Needed complete balcony decking, waterproofing and floor finishing. Very good presentation on the work process. I reached out to several companies, none were as professional as Capital. Reasonable price fantastic work, good communication. Robb showed a sample of the layers, measured and took the photos of the project and came up with an estimate quickly.”
“I had the pleasure to work with Alexander and Abraham during the project. He was super attentive, professional, on time and gave me all the information I needed. Grateful I found a company around the holidays that was still able to make it out and repair my condo’s stairs. They re-sealed and waterproofed it all. Thanks again and Happy Holidays!!”
When the damage is contained, yes. We assess how far the water has traveled during a free inspection and recommend targeted repair or full rebuild, whichever actually solves it.
A stain means water is already getting through the membrane. It will not stop on its own, but caught early, repairs are far smaller than after the framing is involved.
Yes. We waterproof and repair exterior elevated elements to current code and can work from your inspection findings to bring your balconies into compliance.
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.
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.
