Capital Deck & Stair Waterproofing

Repair the Stairs Before They Become a Hazard

Failing exterior stairs are a safety problem, not just a cosmetic one. Cracked or hollow treads, flexing steps, and rusted stringers all mean water has been in the assembly, and stairs carry people, so the margin for error is small.

We repair and resurface exterior stairs and landings, replace failed treads, and where a rebuild makes more sense, we design and fabricate custom iron based precast staircases built for minimal maintenance, most projects backed by our 8-year warranty.

What Our Customers Say

★★★★★

“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!!”

“Great services. My parents were happy with the results. We had heavy rains in my area recently and needed our stairs fixed asap. Highly recommend”

“At first I was skeptical I won’t lie. I think it’s just because of the busy season I didn’t get the best reading on if they were a good and professional company. After speaking with them a few times, I decided to give them a chance and I didn’t regret it at all. Thank gd lol. I’m very picky on who I give my money too…especially in this economy. But they were professional, quick, clean and did all my stair waterproofing at my house. Thanks again.”

FAQ

Your Questions, Answered

Do you replace individual stair treads?

Yes. We replace failed treads and rebuild landings, then waterproof the finished assembly so the repair lasts.

What are iron based precast staircases?

A stair system we design and fabricate that pairs precast treads with an iron structure, a durable, minimal-maintenance replacement for stairs that keep failing.

Repair or full rebuild, how do I know?

We assess the treads, stringers, and substrate during a free inspection and recommend targeted repair or a rebuild, whichever protects your property and your budget best.

How much does waterproofing cost in Los Angeles?

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.

How long does the job take?

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.
