One of the oldest cities in the county, which means a lot of decks are on their second or third coating.
Compton is one of the oldest cities in Los Angeles County, the eighth to incorporate back in May 1888. Age shows up in exterior work. A deck or balcony that has been recoated two or three times over the decades has layers that no longer bond to each other, and putting a fourth coat on top of that buys a season at best.
We would rather find out what is actually under there. Sometimes the substrate is sound and the job is a proper tear off and rebuild of the surface. Sometimes the framing underneath has been taking water for years and that has to be dealt with first. Either way, guessing is expensive.
Just over 55 percent of occupied homes are owner occupied, so this is a mix of homeowner decks and stairs alongside multi unit walkway work in this part of the Gateway Cities. Both sides of that split tend to involve original construction details that predate anything we would build today.
On older buildings the flashing is usually the story. Deck-to-wall junctions were often finished with a bead of mastic and bent metal that was never lapped behind the wall finish. That works while the mastic is flexible. Twenty years of sun later it is a crack.
Compton sits on flat ground south of downtown Los Angeles, close enough to the harbor plain that marine air still reaches it, so corroded fasteners and rusted edge metal turn up more often here than the inland cities further east.

We can, and it will fail again. Compton is one of the oldest cities in the county and multi-layer buildups here have usually lost bond between layers. Tearing off to a known substrate is the only version that lasts.
Compton was the eighth city in Los Angeles County to incorporate, in May 1888. A lot of what we open up has original flashing and drainage details that were never meant to still be in service.
Yes. Owner occupancy runs about 55 percent, so it is a genuine mix. Shared walkways and open stairs on income property are a regular part of the work here.
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.
