How does Del Mar's climate affect this service?
Coastal homes in Del Mar run cooler than inland but still benefit from a top-up to R-38 and aggressive air-sealing. Marine humidity migrates through any open chase, so we hunt those leaks first before insulation goes in.. Coastal crawlspaces — especially on bluff homes in Solana Beach and Del Mar — see real moisture loads.
Should I encapsulate or just insulate the floor?
Depends on moisture. If the crawlspace is dry and well-vented, subfloor insulation plus a vapor barrier on the ground is enough. If it stays damp, we move the insulation to the foundation walls and seal the vents — full encapsulation. We run a moisture meter on the first visit.
Are the existing batts worth saving?
Sometimes. If they are dry, intact, and still on hangers, we top up. If they are sagging, wet, or rodent-fouled, we pull them out and start fresh. Either way the rim joist work is what changes the comfort upstairs.
