What Los Angeles Homeowners Say About Warmline Insulation Co.
Reviews tell you what a contractor’s marketing never will. Since 2011, we have earned our reputation in Los Angeles one attic at a time, and the feedback below comes from real customers who dealt with real problems: rooms that would not cool in August, energy bills that climbed every summer, and crawl spaces that made the whole house smell. Neil Ashford and our crew read every review. We use them to stay sharp.
Recent Reviews
“Our 1950s house in Westchester had maybe two inches of old insulation in the attic. The upstairs bedrooms were unbearable by 4pm. Warmline blew in Owens Corning fiberglass to R-38, air sealed the top plates, and by the next afternoon the rooms held at 76 without the AC running constantly. The crew laid down plywood walkways so we can still use the attic for storage. Clean job, no mess left behind.”
Eric W. – Westchester, Los Angeles
“I called three companies about my crawl space. Warmline was the only one that went under the house before quoting, photographed everything, and explained that the damp smell was coming from exposed dirt and a torn vapor barrier from the original build. They encapsulated the whole crawl space, sealed the vents, and installed a new 12-mil barrier over the entire floor. The smell was gone within two days. That was eight months ago and it still smells neutral down there.”
Claudia F. – Sherman Oaks, Los Angeles
“I had blown-in cellulose from the 90s that had settled down to almost nothing in half the attic. Warmline removed all of it, checked the wiring, and installed Rockwool batts. They found a bathroom vent that was dumping moist air directly into the attic and fixed that too. The difference in our gas bill last winter was noticeable by the first month. Neil walked me through the whole job before they started and the final price matched the quote exactly.”
Kevin Y. – Eagle Rock, Los Angeles
“The north wall of our condo was always cold in winter and the HOA wouldn’t touch it. Warmline dense-packed the wall cavity with GreenFiber cellulose through small holes they drilled from the inside, then patched and repainted perfectly. You cannot tell where they worked. The wall is warm now. What impressed me most is they got it done in one day and left the unit cleaner than they found it.”
Eduardo T. – Miracle Mile, Los Angeles
“We have a flat roof with almost no attic access, which scared off two other insulation companies. Warmline’s techs went through the ceiling in the hallway and spray foamed the entire roof deck with Icynene. The contrast in our living room temperature during the last heat wave was dramatic. They were upfront that this was a specialized job, quoted it properly, and completed everything in a single visit. The 90-Day Done Right Promise was in writing on the estimate, which is more than anyone else offered.”
Eric W. – Westchester, Los Angeles
“I scheduled a home energy audit because I was sick of guessing which part of the house was the problem. The audit showed the attic was only part of it; the rim joists in the crawl space were leaking air like crazy. Warmline handled the attic insulation and the rim joist sealing themselves, then gave me a prioritized list for the rest. Not pushy. No upsell. Just a clear explanation of what my house needed and what it didn’t. Since the work, our summer electric bills have dropped by roughly a third.”
