Deck Waterproofing in Carson
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsAbout three quarters of Carson homes are owner occupied, and the marine air still gets to every one.
Takes about 30 seconds. No obligation, no pressure.
About 13 miles south of downtown Los Angeles, in the South Bay and Harbor regions, Carson runs about 74 percent owner occupied. That figure changes the conversation. Most of our Carson customers live with the deck they are asking about, so the priority is doing it once rather than patching it through another season.
Being this close to the harbor means marine air is a constant. Salt does slow damage to fasteners, flashing and the edges of a coating, and it does not need rain to keep working. We detail the terminations and the metal accordingly rather than treating it as an inland job.
The housing is largely postwar single family, which sets the scope: rear decks, patio covers, entry stairs and second floor balconies over garages. Those decks are often original, and original waterproofing does not survive that many decades of sun.
There is local history in the ground here as well. In 2011 Shell was ordered by the Los Angeles Regional Water Quality Control Board to clean up the Carousel Tract neighborhood after benzene and methane gas contamination was found, along with soil and groundwater contamination. Where a job involves excavation at grade, we confirm what applies before digging.
Above grade the work is what it is anywhere: find where water gets in, cut out what has rotted, rebuild it, and lay down a system that drains rather than one that only sheds.

A local crew looks at the actual deck, and the quote comes back itemized.
It shortens how long the details last. Salt air works on fasteners, flashing and coating edges continuously, wet or dry, so the field of a deck can look sound while the perimeter is finished.
It can affect anything at grade. Shell was ordered by the Regional Water Quality Control Board in 2011 to clean up that neighborhood after benzene and methane gas contamination. We check requirements with the city before any excavation.
Fix the cause, not the symptom. Correct the fall so the deck drains, replace framing that has gone soft instead of coating over it, and detail the wall junction and thresholds so the leak stays gone.
Protect the deck before the next storm. Tell us what you are seeing and we will come look, no obligation.
