Walt Brenner started this company over 25 years ago with a simple premise: homeowners deserve straight answers, upfront pricing, and a contractor who shows up when they say they will. That hasn’t changed. When you call Walt’s Insulation, you’re not reaching a national call center or a franchise rep who outsources the actual work. You’re reaching a local team – background-checked, uniformed technicians – who do the job themselves and stand behind it.
We serve Anaheim and the surrounding communities throughout Orange County. Whether your house runs hot in the summer, your energy bills are climbing, or you’ve found critter damage in the attic and need removal and re-insulation, we can usually get someone out fast. Same-week scheduling is the norm, and in urgent situations we do what we can to move faster.
Fast, Local Attic Insulation
Attic insulation near me searches happen for a reason – people want someone close, someone who can actually come out this week, not three weeks from now. We cover Anaheim and the surrounding Orange County communities, and we don’t use subcontractors. The crew that shows up is our crew.
For most jobs in Anaheim and neighboring cities, we can schedule an estimate within a day or two and complete the installation shortly after. If you’ve got an active problem – significant heat loss in winter, an attic that’s clearly been compromised by animals, or a situation where your current insulation is damp or degraded – call (657) 214-8224 and tell us what’s going on. We’ll figure out the fastest path to getting it fixed. No trip charge inside our service county, and estimates are free.
Seniors and veterans get 10% off, always – no need to ask at the end of a job. And if you’ve already got a written estimate from another contractor, we’ll give you a free second opinion. That offer stands for anyone in our service area.
Areas We Cover
Walt’s Insulation is based in Orange County and serves a wide stretch of communities across the region. Anaheim is our core market – our team knows the housing stock here, the climate patterns, and the specific insulation challenges that come with older tract homes near the canyon areas and newer builds closer to the 91 freeway corridor. For a full breakdown of what we do and what Anaheim homes typically need, visit our Attic Insulation in Anaheim page.
Beyond Anaheim, we regularly work in:
- Yorba Linda – Homes here, especially those backing up to the Chino Hills terrain, often deal with temperature swings that exposed or thin attic insulation can’t handle. We see a lot of blown-in top-ups and radiant barrier installs in this area.
- Brea – A mix of older and newer construction. Older homes near downtown Brea frequently have compressed or damaged fiberglass batts that are well past their useful life.
- Placentia – Solid suburban housing stock, but we find a surprising number of attics here with inadequate air sealing underneath the insulation – which is why the insulation alone isn’t doing its job.
- Villa Park – Larger homes with bigger attics mean more surface area to cover. We size jobs accurately and price them upfront before any work starts.
- North Tustin – Rolling terrain and older hillside properties often have non-standard attic configurations. Our crew has done enough of these to know what to expect.
- Tustin – Fast-growing area with a range of housing ages. Newer construction here sometimes still comes in under-insulated from the builder.
- San Juan Capistrano – A bit further south, but we cover it. The coastal-adjacent climate here is different from Anaheim – less extreme heat, but moisture and condensation issues can be more common.
If you’re not sure whether we cover your specific neighborhood, call (657) 214-8224. We’ll tell you straight.
What Attic Insulation Actually Does for an Anaheim Home
Anaheim gets hot. Not Phoenix hot, but Southern California summers push attic temperatures well past 130 degrees on exposed dark roofing, and that heat radiates down through the ceiling into living spaces below. The right attic insulation – combined with proper air sealing and, in many cases, a radiant barrier on the underside of the roof deck – creates a thermal boundary that keeps conditioned air where you paid for it to be.
The other side of the equation is winter. Anaheim winters are mild but not nothing. Attics that leak air around recessed lights, plumbing penetrations, and HVAC equipment let warm air escape constantly. Your furnace runs longer. Your bills go up. Most homeowners don’t realize how much of that is attic-related until they see a blower door test or a thermal camera scan during a home energy audit.
We install products from manufacturers we trust: Owens Corning blown-in and batt products, Johns Manville fiberglass, Knauf and GreenFiber cellulose, CertainTeed batts, Rockwool for fire-rated and acoustic applications, and Icynene and Demilec spray foam for air sealing and encapsulation work. The right product depends on what your attic needs – we don’t push one material because it’s easier for us to install.

What to Expect When You Call Walt’s Insulation
A lot of people searching “attic insulation near me” have already had a bad experience: a contractor who gave a vague estimate, asked for a deposit, and then disappeared. Or a crew that showed up, did fast work, and left behind an attic that still didn’t perform. We hear these stories regularly.
Here’s how a job with us actually goes:
- You call (657) 214-8224. A live person answers – not voicemail, not an after-hours service that takes a message and maybe calls back tomorrow. Someone picks up and talks with you about what’s going on.
- We schedule a visit. One of our uniformed, background-checked technicians comes out to assess the attic. We look at existing R-value, air sealing, ventilation, moisture, and any signs of pest activity. We don’t just measure square footage and quote a number.
- You get upfront pricing. Before any work starts, you know what it costs. No surprise add-ons at the end. If you’ve already got a written quote from someone else, we’ll give you a free second opinion before you decide.
- We do the work. Our crew – not a subcontractor – completes the installation using the products we’ve specified. We clean up after ourselves.
- The Done Right Promise covers you. If something isn’t right, we come back and make it right. That’s not a marketing line – it’s a lifetime workmanship commitment, and Walt Brenner puts his name on it personally.

What Our Customers Say
"Crawl space was wet every spring. They laid the heavy liner, sealed the vents, and put a dehumidifier down there. Floors are warm and the moisture meter he left reads fine now. He still answers when I text him a reading."
- Devon Pierce"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
- Linda Baumgartner"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."
- Helen Tran
