Insulation Company in Del Mar, CA
Insulation in Del Mar is a different conversation than it is ten miles inland. Our crews work on original beach cottages from the 1940s and 1950s that were built with almost nothing in the walls, and on newer blufftop homes where ocean moisture finds every seam. The mild coastal air means the complaint we hear most is cold, clammy rooms in late spring, not summer heat. If you’re in Del Mar and your home feels damp or drafty, call us at (909) 768-6501 and we’ll help you figure out exactly what’s going on.
Why Del Mar Homes Are Different
The Village around Camino del Mar and 15th Street is packed with post-WWII beach bungalows and mid-century cottages. These homes were built as seasonal escapes. Builders assumed the ocean breeze would handle comfort, so attics got a thin scatter of fiberglass or nothing at all, and walls were left empty. Now these houses are full-time residences, and the gaps show up as rooms that never quite feel warm in February and never quite feel dry in June.
Del Mar sits in CEC Climate Zone 7, a marine climate where the summer marine layer, strongest from May through July, keeps temperatures moderate but pushes persistent interior dampness into under-insulated homes. The primary issue here is not heat gain, it’s moisture that settles into drywall, hardwood, and stored clothing. That same ocean air carries salt, which degrades standard fiberglass batts faster than homeowners expect. Most of Del Mar also falls within the California Coastal Zone, so exterior insulation changes like adding rigid foam to walls or altering roof assemblies can trigger a Coastal Development Permit review. Contractors from inland San Diego County markets often miss that step in their bids, and homeowners find out months later.
Our Main Del Mar Services
Del Mar homeowners call us about two things most often: attic insulation that stops the late-spring chill, and spray foam that seals the gaps where ocean air sneaks in.
Attic Insulation in Del Mar
Many Del Mar attics hold a 60-year-old layer of matted fiberglass that stopped working long ago, often damp from the marine layer and settling low in the joists. Our Attic Insulation in Del Mar work starts with removing whatever is up there, checking for moisture intrusion, and installing a vapor-managed assembly that suits Zone 7 conditions. For the Village cottages, we commonly air-seal the top plate and bypasses before blowing insulation to the proper R-value. Every job gets a written price before work begins.
Spray Foam Insulation in Del Mar
Blufftop and Del Mar Heights homes with complex rooflines benefit from spray foam, which seals irregular framing in a way batts cannot. Our Spray Foam Insulation in Del Mar service is often selected for crawl spaces too, where moisture from the coastal air moves through vents and makes floors cold. We match the right foam product to the assembly, and we mist the crawl space surface before application so the foam bonds cleanly in the damp marine environment.

FAQs About Insulation Company in Del Mar
Most Del Mar estimates happen within one business day, and we can usually begin work within the same week. If you have a specific timeline, like a tenant move-in or a baby on the way, tell us when you call and we’ll schedule around it. Call (909) 768-6501 to check current availability.
Interior insulation work like attic or crawl space upgrades typically does not require a Coastal Development Permit. Exterior changes, such as adding rigid foam to walls or altering a roof assembly as part of a retrofit, can trigger that review. We flag this early in every Del Mar estimate so you’re never surprised by a city requirement mid-project.
That’s the marine layer. From May through July, ocean air sits over Del Mar and pushes moisture into under-insulated homes, especially the original 1940s – 1960s cottages in the Village. The fix is usually a combination of air sealing and insulation with moisture-managed assemblies, not just adding more fiberglass. Call (909) 768-6501 and we’ll walk through what your attic actually needs.
