Durable waterproof coatings that protect walking decks, roof decks, and balconies from water intrusion.

Three quarters of Van Nuys rents, so most of this work is apartment walkways, stairs and balconies.
Renters occupy 73.9 percent of the housing stock in Van Nuys, with owners at 26.1 percent. That single number tells you what the waterproofing work looks like here. It is shared exterior walkways, open stairs and stacked balconies on income property, where a failed surface is a liability question and a tenant complaint at the same time, not just a homeowner's weekend project.
Van Nuys is the most populous neighborhood in the San Fernando Valley, home to Van Nuys Airport and the Valley Municipal Building, so it carries the Valley's largest single concentration of buildings under one jurisdiction. Volume like that means a lot of similar buildings failing in similar ways at similar ages.
The Valley climate is subtropical and hot-summer Mediterranean: long, hot, dry summers and short, mild winters with chilly nights and sporadic rainfall, with summer days typically hotter and winter nights colder than the Los Angeles Basin. That pattern is quietly brutal on a deck. Months of heat cycling open up cracks and lift edges, and then the rain arrives all at once and finds every one of them.
Failures here usually trace back to the dry season, not the wet one. What we find on opening up is a threshold or a post base that has been letting water into the framing for two or three winters, with the visible field of the walkway still looking serviceable.
On occupied buildings the sequencing is half the value. We work run by run, protect what stays in service, and hand each section back before the next comes out of use.
