Licensed contractors need a La Puente business license to pull a permit here. We carry one.
If you are performing work and obtaining a permit in La Puente as a licensed contractor, you also need a City of La Puente business license. It is a small step that stops a job dead when a contractor turns up to file without one, and it is the kind of thing an out of area outfit finds out at the counter.
The city covers about 3.5 square miles of mostly flat land in the San Gabriel Valley, with 9,919 housing units and around 58 percent of occupied homes owner occupied. Flat ground means the deck problems here are about slope and ponding rather than runoff. A surface with not quite enough fall holds water for days after a storm.
Ponding is not just a coating question. Water standing on a surface loads it, works into any crack under pressure, and keeps the substrate wet long after the weather clears. That is why a deck that ponds fails from underneath while the top still looks presentable.
The correction is geometry. We build fall back into the deck with a tapered substrate, put drainage at the low point, and then waterproof over a surface that actually moves water. Coating a level deck is selling a repeat visit.
Being inland, the wear cycle is heat driven. Summer works the edges and penetrations loose over months, then the first real storm exploits every one of them at once.

No. Standing water is a slope problem, not a coating problem. We build fall back in with a tapered substrate and set drainage at the low point, then waterproof over a surface that actually sheds.
Mostly flat, covering about 3.5 square miles in the San Gabriel Valley. That is why ponding rather than runoff drives most of the failures we see here.
