Deck Waterproofing in Norwalk
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsNorwalk wants contractors carrying a city business license, and we sort that before filing.
Takes about 30 seconds. No obligation, no pressure.
Contractors working in Norwalk must obtain a city business license from the Finance Department. It is a routine step, but it is a step, and it is where an out of area contractor discovers on the morning of filing that they cannot pull the permit yet.
Norwalk is 64.6 percent owner occupied across its 28,455 housing units, with 97.8 percent of the stock occupied, which is high for this part of the county. Most of our work here is homeowner work: rear decks over patios, entry stairs that have gone soft at the nose of the tread, and balconies that have started marking the stucco beneath them.
The city is bordered by Downey, Bellflower, Cerritos, Artesia and Santa Fe Springs, all flat inland ground. Nothing about the site helps a deck drain, so the fall built into the surface is the only thing moving water, and when that fall is lost the surface starts holding water over its own weak points.
Stucco staining under a balcony is the most common thing people call about, and it is usually misread. The stain is not the leak. It is the exit. The water got in at the deck edge, a post base or the door threshold, ran along framing, and came out at the first opening in the wall assembly below.
So we find the entry before we quote the fix. That means probing the deck, reading moisture at the wall line, pulling a rail base or lifting edge metal if the readings call for it. A repair aimed at the stain does nothing at all for the leak.

Yes. A contractor working in Norwalk has to obtain a City business license from the Finance Department before the Building and Safety Division will issue the permit. We handle that ahead of filing so it is not discovered on the day.
The balcony is where the water got in, but the stain is only where it came out. The entry point is usually the edge, a post base or the door threshold. Repairing the stucco without finding the entry leaves you with a fresh stain next winter.
