Same City, Very Different Weather on Your Deck
The mountainous terrain around Los Angeles gives the area a large number of distinct microclimates, with extreme variations in temperature over surprisingly short distances. The average July maximum at the Santa Monica Pier is 70 degrees while it is 95 degrees in Canoga Park, 15 miles away. That is not a talking point, it is a specification problem, and the same coating is not the right answer at both addresses.
Only 36.3 percent of housing units in Los Angeles are owner occupied, so the majority of what we do in the city is income property: shared walkways, open stairwells and stacked balconies where a failure travels down through the building rather than staying put.
We look at where the property actually sits before specifying. Sun exposure, wind, proximity to the water and how the water leaves the deck matter more to how long a repair lasts than anything printed on the bucket. A deck baking through a Valley summer is fighting thermal movement. A deck near the water is fighting salt.
The failure itself is consistent citywide even when the cause is not. Water gets behind the coating at a threshold, a post base or the wall junction, runs along the top of the framing, and exits somewhere that looks unrelated. Owners describe it as sudden. It has almost always been in progress for years.
We work across the whole city on walkways, balconies, stairs, magnesite and exterior decks, and we fabricate custom iron and precast staircases when a run has gone past the point where repairing it is honest.

Waterproofing in Los Angeles: Your Questions
Does my neighborhood really change the specification?
It does. Average July highs run 70 degrees at the Santa Monica Pier and 95 degrees in Canoga Park, 15 miles apart. Heat cycling and salt exposure are different problems and they call for different details.
What do I need before filing with LADBS?
An Angeleno account. It is the single City of Los Angeles login required to use ePlanLA or PermitLA, and it also covers construction services at other city departments. We file and carry the inspections.
Do you work mainly on apartment buildings?
A majority of the time, because owner-occupied units are only 36.3 percent of the city's housing stock. Most of our LA work comes from owners, HOAs and property managers rather than homeowners.
