How does San Diego's climate affect this service?
Central San Diego housing stock spans 1920s craftsman bungalows on raised post-and-pier through 1980s slab-on-grade tracts. San Diego foundation work splits between cripple wall and post-and-pier rebuilds in older homes and slab or perimeter underpinning in newer ones. Plumbing-leak voids under slabs are a frequent driver here.. We account for local conditions in every job.
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.
