How does Carlsbad's climate affect this service?
North Coastal foundations deal with marine humidity year-round and the periodic winter storm surge against hillside lots. Carlsbad work usually combines drainage retrofit with helical pier underpinning. Older 1970s beach stock often has post-and-pier raised foundations needing seismic-retrofit work.. 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.
