Crawl Space in Del Mar, CA.
Crawl Space for Del Mar homes, done by an experienced San Diego County foundation crew. Most pre-1980 San Diego homes are raised foundations with a crawl space underneath. The post-and-pier system, cripple walls, and floor framing all live down there, out of sight, until something goes wrong.
Why is crawl space different in Coastal San Diego?
Coastal crawl spaces deal with persistent humidity and salt-air corrosion on hardware. Vapor barriers, treated lumber, and stainless or galvanized fasteners are standard.

How does Del Mar's climate affect this service?
Del Mar custom estate foundation work spans bluff-top homes along Camino del Mar facing direct ocean exposure, Beach Colony and Olde Del Mar historic Mediterranean stock, and Del Mar Mesa hillside settlement on the inland side. Salt-corroded rebar and bluff erosion drive most of the village scope.. Coastal crawl spaces deal with persistent humidity and salt-air corrosion on hardware.
What is a cripple wall and why does it matter?
A cripple wall is the short stud wall between the perimeter foundation and the first floor on a raised home. In older San Diego homes (pre-1960) the cripple wall was often built without bolts or shear sheathing; in an earthquake it can collapse and drop the house. Brace-and-bolt retrofit adds plywood sheathing and anchor bolts to make the wall behave as designed.
Should I encapsulate my crawl space?
Sometimes. Full encapsulation (sealed vapor barrier, conditioned air, dehumidifier) is overkill for most San Diego homes because our humidity is low. A standard 6-mil sealed vapor barrier on the dirt is usually enough. We recommend full encapsulation only for homes with persistent moisture or chronic mold.
