Insulation Contractor in Lompoc - Sealed Attics and Warmer Floors
D&M Santa Maria Insulation Company insulates attics, walls and crawl spaces in Lompoc, CA, and seals the gaps first so the new insulation isn't fighting a draft. We also pull out old material that's soaked or dirty.

I check how many inches are up there, what shape it's in, and where air leaks in.
Request an estimateLompoc: older floors over crawl spaces
Lompoc is mostly houses, with older ones close to the old downtown and newer tract streets spread out from there. A lot of the older homes we get into sit on raised floors over a crawl space, and their attics often still hold whatever went in when the house was built, packed down thin after all these years. Neighbors in Vandenberg Village call us about the same hot bedrooms and cold floors, but I don't assume one attic looks like the next until I've been up in it.
On the lower side of town, closer to the river, we pay extra attention under the floor, because insulation that has ever gotten wet doesn't recover and has to come out before anything new goes in.
Working in Lompoc: permits, licenses and what sets the price
Before our crew starts in Lompoc, I check with the city's Building Division on whether your job needs a permit, because the city's list covers altering a house, repairs and electrical or mechanical work but doesn't name insulation by itself. If they say it does, we take care of the application and set up the inspections, and from then on the city's inspection dates shape the schedule more than our crew does. The city also requires every business working here to hold a Business Tax Certificate, contractors from out of town included, so that's a fair thing to ask anyone you're thinking of hiring. Price comes down to what's already up there and what shape it's in, how many gaps need sealing, how easy the attic or crawl space is to get into, and whether foam is worth it or loose fill will do. I come out myself to look at all of that and write the estimate, so you see the number for your house.
Our truck comes over from Santa Maria with the blowing machine and the removal vacuum on board, so a Lompoc job doesn't stall waiting on a second trip for gear. We work the same way in Buellton and the other cities around us, and the steps don't change because the address does.
Services in Lompoc, CA
Attic insulation
When the upstairs or a back bedroom runs hot, the attic in an older Lompoc house usually has only a few inches left, and it's thinnest out by the eaves. We measure what's there, seal the gaps, and bring coverage up evenly so the edges get as much as the middle, without burying the eave vents the attic needs to breathe.
Insulation removal
Insulation that got wet or filled up with droppings has to come out, because new material laid on top just covers the problem. We vacuum it out, bag it and clean up before anything new goes in.
Crawl space insulation
Cold floors in Lompoc's raised-floor homes usually trace back to a crawl space where the insulation has sagged or dropped out from between the joists. We check for damp first, then fit insulation that stays snug against the underside of the floor.
Crawl space vapor barrier
Under houses on the lower side of town, moisture coming up from the dirt works against any insulation above it. We lay a vapor barrier, a sheet that holds ground moisture down, across the crawl space floor and seal the seams.
Attic air sealing
Drafty rooms and a high power bill often come from gaps around can lights, pipes and the attic hatch more than from thin insulation. We close those openings first, so whatever goes on top isn't fighting moving air.
Closed-cell foam insulation
When the ductwork lives in the attic or a crawl space stays damp, closed-cell foam insulation, a dense foam that seals air and blocks moisture as it goes on, is worth what it costs. For most Lompoc attics, though, I'll tell you that sealing the gaps and topping up loose fill does the job for less.

Frequently asked questions
How much does it cost to insulate a house in Lompoc?
Your cost mostly comes down to how much area we're covering, how many inches are already there, and whether old material has to come out first. Older Lompoc houses with soaked or dirty insulation, or lots of gaps to seal, run more than a clean attic that only needs a top-up, and foam costs more than loose fill. I give you a written figure after I've seen the house.
Does insulation work in Lompoc need a permit if it touches wiring or ducts?
Yes, the city's permit list says electrical and mechanical work needs a permit first, replacing systems included, and adding or moving electrical lines always does. So if your job means moving wiring or a can light, or replacing ductwork, plan on a permit. We take care of the application and set up the inspections.
How do I check if my Lompoc home is in a flood zone?
Start with FEMA's flood map viewers, which FEMA calls the best place to begin understanding the official flood hazard for an area. Where an effective map has data for your address, that data sets the minimum flood insurance requirements. It's worth knowing before we plan anything under your floor.
Does river flooding in lower Lompoc affect crawl space insulation?
It can, because federal river forecasters list flooding as a threat to lower Lompoc, especially around Floradale Ave, once the river reaches 15 feet. That's a river level, not a ruling on any one property. If water has ever been under your house, the insulation down there should come out, and we check for that before anything new goes in.
How long does it take to insulate an attic in Lompoc?
Your timeline mostly turns on whether old material has to come out first and how much sealing the attic needs, and I'll tell you what I expect after the visit. When a permit is involved, the city won't inspect without the stamped, approved plans on site, so we keep them there to avoid a missed inspection. With foam, you'll be out of the house until the re-entry time passes, when it's safe to come back in.
Which building code applies to a home project in Lompoc?
The city's Building Division says projects starting January 1, 2026 must be designed to the 2025 California Building Codes. Projects already underway can stay on the older codes, but only as long as work keeps moving. If you've got a job in progress, it's better not to let it sit.
