West Covina no longer takes applications by email, which catches out anyone working from old notes.
The West Covina Building Division is no longer accepting applications via email, effective immediately per the city. Small change, real consequence: an application sent the old way is not in a queue, it is nowhere, and nobody finds out until someone chases it. We file the current way.
The city has 34,834 housing units at 2,172 per square mile, with 59.9 percent of the occupied ones owner occupied, in a San Gabriel Valley climate where summer temperatures average above 73 degrees. That sustained inland heat is what works a deck surface loose at the edges over a season, well before any rain gets the chance to exploit it.
Owner-heavy stock means a lot of single family decks, rear stairs and balconies that have been in service for decades and repaired more than once. Layered coatings that no longer bond to each other are the normal find here, and adding a fresh layer over them is money spent on a problem that comes straight back.
The remaining 40.1 percent is rented, so shared walkways and open stairs are still a steady part of the work. Those fail in the traffic lane first, and the water that gets in there does not stay where it entered.
We open the low point and read moisture in the sheathing before pricing. That is what separates a surface rebuild from a framing repair, and it is the only way to give a number that holds once the demolition starts.

No. The West Covina Building Division is no longer accepting applications via email. An emailed set is not in the queue at all, so we file through the current process instead.
The San Gabriel Valley has a hot-summer Mediterranean climate with summer temperatures averaging above 73 degrees. Sustained heat works terminations loose over months, and the rain simply finds what the heat opened.
Not over a failed system. With 59.9 percent of the city's 34,834 housing units owner occupied, most decks here have been coated more than once, and stacked layers that no longer bond will pull a new coat off with them.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
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.
