Insulation Company in Westwood, CA
Insulation work in Westwood comes down to the homes themselves. Most houses here were built between the 1920s and 1950s, which means lath-and-plaster walls, minimal original insulation, and attic spaces that were never designed for modern energy standards. We see Spanish Colonial and Tudor homes every week with empty wall cavities and attics that bake upstairs bedrooms during summer heat waves. Aspen Attic Insulation serves Westwood with attic insulation, spray foam, and blown-in insulation, always starting with a written price before any work begins. Call (213) 376-3824 to talk it through with a live person, day or night.
Why Westwood Homes Are Different
Westwood’s housing stock wasn’t built for the way we cool and heat homes today. The 1920s-1950s single-family detached homes that dominate the neighborhoods around UCLA and the hillsides came with little more than a thin layer of whatever was cheap at the time, and many now have none at all. Lath-and-plaster walls are beautiful and solid, but they were framed before insulation was standard, and the cavity space is often too narrow for conventional batts. That pushes homeowners toward blown-in insulation, which fills irregular cavities without tearing into original plaster.
The rooflines add another layer. Many Westwood homes sit on hillside lots with complex roof pitches, dormers, and original shake roofs that were never air-sealed. We regularly find attics coated in fine dust and debris that’s been pulled in through gaps around the roof deck. That’s a telltale sign the attic needs air sealing before any insulation goes in. Otherwise you’re just burying the problem. Summer heat waves are the other driver. Daytime temperatures in the 90s turn uninsulated upstairs bedrooms into ovens by late afternoon, and that’s when Westwood homeowners start calling us. The coastal climate keeps heating loads modest, but cooling is the real issue in August and September.
Our Main Westwood Services
Westwood homeowners call about three jobs most often: bringing an old attic up to current insulation depth, sealing an attic with spray foam, and retrofitting walls and attic cavities with blown-in insulation. Each one gets its own page for Westwood. Here’s what they cover.
Attic Insulation in Westwood
Most Westwood attics we enter have either bare joists or a tired layer of fiberglass that’s compressed to half its original depth. We remove what’s failing, air-seal the gaps around the top plates and penetrations, and install fresh insulation to the depth that fits the roofline and the home’s cooling needs. On hillside lots, attic access can be tight, and venting has to be reworked so the roof deck can breathe. Every job carries a written price before we start and is backed by the 365-Day Done Right Promise. See the full detail on our Attic Insulation in Westwood page.
Spray Foam Insulation in Westwood
Spray foam does two jobs in one pass. It seals air leaks and insulates in a single application, which matters in older Westwood attics where the shake roof has been pulling dust and outside air in for decades. We use open-cell and closed-cell foam depending on the cavity, and the material expands into odd joist bays and dormer corners that batts can’t reach. Technicians are background-checked and arrive in marked uniforms with photo ID badges, and you’ll know the tech’s name before anyone shows up at your door. Details are on the Spray Foam Insulation in Westwood page.
Blown In Insulation in Westwood
For the 1920s-1950s walls and attics that dominate Westwood, blown-in insulation is often the only practical retrofit. We blow loose fiber into wall cavities through small access holes and fill attic floors to the full depth the space allows. It preserves the original lath-and-plaster and stucco finishes, which matters when you’re keeping a Spanish Colonial’s character intact. The material settles into the irregular shape of an old cavity in a way rigid batts never will. Read the specifics on our Blown In Insulation in Westwood page.
