Attic Insulation Near You in Santa Monica, CA
When you search “attic insulation near me,” you want someone local who can actually show up – not a national call center that farms your job out to whoever is available. Walt’s Insulation has been serving Santa Monica and the surrounding Westside communities since 2000, and a live person answers our phone 24 hours a day, every day of the year. Call us at (424) 396-5828 and you’ll reach a real person, not a voicemail.
We’re locally owned and owner-operated, with a published address and license number you can look up. That’s the kind of accountability that a franchise can’t offer – and the kind of accountability Walt Brenner has built this business on for over 25 years.
Fast, Local Attic Insulation
Most of our Santa Monica customers get a same-day or next-day appointment. We run a tight service area by design – keeping it local means we’re never overbooked, never sending a crew that’s three hours away, and never leaving you waiting a week for a basic attic insulation job. There’s no trip charge for homes inside our service county, and we carry upfront pricing to every estimate so there are no surprises when the job is done.
Our background-checked, uniformed technicians arrive on time, walk you through exactly what they found in your attic, and give you a clear written quote before any work begins. If you’ve already received a written estimate from another company, we’ll give you a free second opinion – no charge, no pressure.
Every job, big or small, is covered by the Done Right Promise: lifetime workmanship, no runaround. If something isn’t right after we leave, we come back and make it right. That’s not a marketing line – it’s the promise Walt Brenner puts his name on.
Areas We Cover
Our home base is Santa Monica, and we work throughout the Westside and South Bay. If you’re anywhere in this part of Los Angeles County, chances are we can get to you fast. Our regular service area includes:
- Santa Monica – our primary service area, where most of our crews are running on any given day
- Culver City – including older ranch-style homes in the Sunkist Park and Fox Hills neighborhoods where under-insulated attics are common
- Beverly Hills – hillside and flat-lot homes alike, where radiant barrier work pairs well with attic insulation to reduce cooling loads
- Marina del Rey – coastal humidity here makes proper attic sealing especially important before adding blown-in insulation
- El Segundo – close to the coast, similar moisture considerations as Marina del Rey
- Ladera Heights – a neighborhood we visit regularly for attic upgrades in post-war construction homes
- View Park-Windsor Hills – hillside homes with complex attic geometry that require experienced crews
- Calabasas – further inland, where summer attic temperatures can exceed 140°F and radiant barriers make a measurable difference

What Makes Westside Attics Unusual
Santa Monica and the surrounding coastal communities have a climate that most insulation guides don’t account for. The marine layer keeps summer temperatures mild near the water – but that same moisture-laden air gets into attics and can degrade fiberglass batts faster than in drier inland areas. We’ve inspected attics in Santa Monica’s Sunset Park neighborhood where the original batts from the 1970s had compressed to half their rated R-value, mostly from decades of ambient humidity.
The flip side: homes in Calabasas and the areas further from the coast deal with radically different conditions – dry heat, attic temperatures that can hit 145°F in July, and cooling bills that dwarf what coastal homeowners pay. A Calabasas attic typically needs both a radiant barrier and a solid R-38 to R-60 insulation layer to get utility bills under control. A Santa Monica attic closer to the beach may need more emphasis on air sealing and moisture management.
We account for all of that. When we quote a job, we’re not plugging your zip code into a national pricing sheet. We’re looking at your actual attic, your actual construction type, and your actual energy situation.
What We Install
We work with manufacturer brands that professional contractors actually trust: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The material choice depends on your attic – blown-in cellulose from GreenFiber is a strong fit for retrofitting older homes with irregular joist spacing; Owens Corning blown fiberglass works well in attics that need fast installation with minimal disruption; Icynene and Demilec spray foam are the right call when air sealing and insulation need to happen simultaneously. We don’t upsell materials – we recommend what your attic actually needs.
Services we provide in and around Santa Monica include:
- Attic insulation (blown-in, batt, spray foam)
- Attic air sealing before insulation install
- Radiant barrier installation
- Insulation removal and replacement
- Attic cleaning and rodent proofing
- Crawl space encapsulation and vapor barrier
- Wall insulation
- Home energy audits

What Our Customers Say
"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
- Nadia Haddad"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
- Arjun Mehta"Spray foam in the garage ceiling under the bonus room. That room used to be unusable in summer. Walt talked me out of foaming the whole attic because it did not need it - saved me a couple thousand and I trust him more for it."
- Bud Larkin
