From dry rot and cracked coatings to failing magnesite, we repair the damage, rebuild a sound substrate, and waterproof it so it lasts.
Patching over a damaged deck rarely lasts, because the real problem is underneath. Cracked coatings, soft spots, and stains on the ceiling below all point to water that has already reached the substrate, and it keeps spreading until the damage is cut out and rebuilt.
Capital Deck & Stair repairs the full assembly: we remove failed material, repair dry rot and cracks, restore worn and failing magnesite, and finish with a waterproof system, 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.”
“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.”
