What San Francisco Homeowners Say About Thistledown Insulation San Francisco
Reviews tell you what actually happens after the quote is signed. Not what a website promises, but what the crew did in someone’s attic on a wet Tuesday in the Sunset. We earn every one of these by showing up when we say we will, laying drop cloths from the front door to the attic hatch, and leaving the space cleaner than we found it. Neil Barron has been running Thistledown Insulation San Francisco since 2003, and the repeat business from San Francisco neighborhoods tells the story better than any tagline could.
Recent Reviews
“Our 1912 Edwardian in the Richmond had maybe three inches of settled fiberglass in the attic. The Thistledown crew vacuumed everything out, sealed the bypasses around the old knob-and-tube penetrations, and blew in Owens Corning to R-38. The bedroom facing the street finally holds heat. They also wore shoe covers the entire time and laid drop cloths down the hallway. My wife noticed the clean-up before she noticed the new insulation.”

“We have a 1980s condo near Stern Grove where the upstairs was always ten degrees colder than the living room. Thistledown diagnosed a vented attic that was barely insulated over the bedroom wing and recommended Johns Manville blown-in fiberglass. The written price matched the final invoice to the dollar. The crew even asked before moving my wife’s boxes away from the hatch. That C.A.R.E. thing is not marketing copy with these folks.”

“Had spray foam applied to the rim joists in our Noe Valley basement. The technician spent twenty minutes explaining how Demilec closed-cell foam would stop the drafts that were running under our oak floors. I appreciated that he didn’t try to upsell us on foaming the entire crawlspace. He gave us the number, we thought about it overnight, and they came back the next week. Same tech, same shoe covers, same careful work.”
Javier S., Noe Valley, San Francisco
“Two kids under four and a very suspicious cat. The Thistledown crew chose a pet-safe GreenFiber product for our attic so the cat could stay home during the job. They also kept their tools quiet during nap time, which I didn’t think was a real request until the tech nodded and started using a hand saw instead of the reciprocating saw. When they finished, they showed me photos of the cleaned-up hallway on their phone. That is respect you don’t see often.”
Bethany B., Glen Park, San Francisco
“Our attic in the Mission had old, compacted insulation from who knows when. I called at 9 p.m. on a Sunday expecting voicemail. A person answered. A person named Paul. He scheduled the estimate for Tuesday and the tech arrived with a clipboard, not a tablet pitch. We got a written price for CertainTeed blown-in fiberglass before a single bag was loaded into the hopper. Knauf was offered as an alternative at a lower price point. Real choices, no pressure.”
Rosa G., Mission District, San Francisco
“The fog in the Outer Sunset means our attic gets damp, and the previous contractor put fiberglass batt directly against the roof sheathing. Classic mistake. Thistledown removed the batts, confirmed the ridge vent was still breathing, and installed Rockwool batts in the floor cavities with proper baffles. The tech explained why Rockwool handles moisture better in our microclimate than the old fiberglass did. I checked the attic three weeks later after a heavy rain. Dry as chalk.”

Why Customers Trust Us
Every review above touches on the same four things, because that is how we work. First, the written price arrives before any work starts, every single time, without exception. You decide with the number in your hand. Second, the technicians who walk through your door are background-checked and uniformed, and they follow the Cedarwell Care Promise: shoe covers and drop cloths on every visit, a photo of the clean-up before they leave, and quiet tools when there are sleeping kids. Third, the 365-Day Done Right Promise is not a marketing line. If the insulation is not done right, we come back and make it right. No debate, no fine print. Fourth, we carry eight brand lines, including Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the product fits the attic and the family, including pet-safe options where a choice exists. Thistledown is the soft fluff of the thistle, one of nature’s lightest insulators. The name is a promise about how carefully we work. If your San Francisco attic needs a second opinion or a first proper insulation job, call (341) 247-0222. A live person answers, day or night.
