Penetrating sealers and protective coatings that keep concrete patios, walkways, and decks protected from water, stains, and wear.
Concrete looks tough, but it is porous: water, oil, and salts work their way in and lead to cracking, spalling, and stains. Once moisture is inside, freeze-free Southern California sun does the rest, drying and stressing the surface season after season.
Capital Deck & Stair applies the right sealer or waterproof coating for your concrete patios, walkways, and decks, protecting the surface and extending its life, most projects backed by our 8-year warranty.

“I had the pleasure of working with Capital Deck recently and had a great experience. I go off of energy and I knew they would be the right fit once the quote to come out went well. Very knowledgeable, professional, on time daily and took them a reasonable amount of days to finish even due to the holidays. I definitely recommend them.”
“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.”
“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.”
Most concrete benefits from resealing every few years depending on exposure and traffic. We will tell you what your surface needs during a free inspection.
Penetrating sealers protect sound concrete invisibly; waterproof coatings rebuild and protect worn or trafficked surfaces. We recommend the right one after seeing the surface.
Yes. Concrete surfaces over living space get a full waterproof deck system, not just a sealer, so the structure below stays dry.
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.
