What West Covina Homeowners Say About Thistledown Insulation West Covina
Reviews tell you what a company does when things get dusty, cramped, and 140 degrees. We earn ours the old way: a written price before anything starts, shoe covers from the front door to the attic hatch, and a photo of the clean-up before we leave. Here is what your neighbors in West Covina, Baldwin Park, and Covina have told us about their attic insulation and spray foam projects.
Recent Reviews
Our upstairs bedrooms were unusable by 2 p.m. every August. Neil’s crew blew in Knauf loose-fill across the whole attic in one morning and the difference was immediate. The hallway stayed covered in drop cloths the entire time and our dog never had to leave the house.
Roger L., Woodside, West Covina
The written quote matched the final invoice to the dollar. They installed Owens Corning batt insulation in the garage ceiling and used a quiet vacuum for the old stuff. My mother-in-law was napping in the next room and never woke up.
Miguel M., South Hills, West Covina
I had three companies tell me I needed a full tear-out. Thistledown sent Neil, who measured the existing R-value, found that half the attic just needed air sealing and a top-up with GreenFiber. Saved us thousands. The photo of the cleaned-up attic floor was in my inbox before the truck pulled away.
Alejandro R., Valinda
We chose Icynene spray foam for our attic because our son has asthma and dust from the old fiberglass was a constant problem. The crew explained every step, covered the hallway with drop cloths, and wore shoe covers the whole time. The air in his room feels different now. It is calmer.
Eduardo R., Cortez Park, West Covina
I called on a Sunday afternoon expecting a voicemail. A real person answered, took my information, and had a technician out Tuesday morning to inspect our attic. The written price came before any work started, exactly as promised. Johns Manville insulation, clean install, zero mess left behind.
Roger L., Citrus, West Covina
The crew used Rockwool batts around the recessed lights in our living room ceiling. They asked before moving the boxes we had stacked near the attic ladder and put the drop cloths down in exactly the path they walked. When they left, our hallway looked like nobody had been there. That matters to my wife.

Why Customers Trust Us
Every review above mentions the same few things: a written price before work starts, a clean floor when the crew leaves, and a product matched to the family rather than the truck inventory. That is not an accident. We install eight insulation brands, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the right material goes into each attic, including pet-safe options where a choice exists. Our technicians are background-checked and uniformed every visit. And the 365-Day Done Right Promise is exactly what it sounds like: if it is not done right, we make it right. No debate, no fine print. Thistledown is the soft fluff of the thistle, one of nature’s lightest insulators. The name is a promise about how carefully we work. Whether you need attic insulation in West Covina or spray foam in Baldwin Park, call us at (831) 480-4947. A live person answers, every time, and you will have your exact written number before we touch a rafter.
