What San Francisco Homeowners Say About Alden Insulation San Francisco
Reviews tell you what a website can’t. They show how a crew actually behaves when the truck pulls up, how the price holds up after the work is done, and whether the guarantee means anything. We ask every San Francisco customer to hold us to The Garrison Standard, the same operating code that has guided Alden Insulation since 2002. The comments below come from real homeowners in this city who dealt with drafty Victorians, zero insulation in Sunset bungalows, and old fiberglass that had to come out before anything new could go in.
Recent Reviews
“Our 1912 flat in the Richmond had newspaper stuffed in the walls and maybe two inches of dust where insulation should have been. The crew removed everything, air sealed the gaps, and blew in GreenFiber cellulose in one day. The difference was immediate. The front bedroom finally holds heat. The written price matched the invoice, exactly.”
Michelle A., Richmond District, San Francisco
“I scheduled a removal after finding rodent damage in my attic insulation in Noe Valley. The tech walked me through what he found, showed me the problem areas on his phone, and gave me a hard number before any work started. He wore a uniform, was clearly background checked, and answered every question I threw at him about R-value. It felt less like a sales pitch and more like an inspection with a plan.”
Adriana H., Noe Valley, San Francisco
“We own a 1950s Marina house where the attic had maybe R-11 in places and bare spots everywhere else. I wanted Owens Corning blown in, and they installed it to R-38, which was the plan we agreed to in writing. The 365-day guarantee was explained before I paid, not buried in an email after. That says a lot about how this company operates.”
Lucia D., Marina District, San Francisco
“I called at 6:40 in the morning expecting a voicemail. A real person answered. By the end of the call I had an appointment window, not a half day of uncertainty. The two technicians showed up on time, in uniform, and got the attic insulated in about five hours. They covered the hallway floor, cleaned up thoroughly, and left my Bernal Heights house tidier than they found it.”
Colleen H., Bernal Heights, San Francisco
“We needed insulation removed from a crawl space in West Portal after a roof leak soaked it through. The estimate was itemized, so I knew the removal and the new Rockwool weren’t some bundled mystery. What impressed me most was the follow through: when a small patch settled after a month, they came back within the week, re-checked the space, and made it right with no charge and no debate.”
Michelle A., West Portal, San Francisco
“I’ve hired contractors in San Francisco who turn into ghosts the moment the check clears. Alden was the opposite. Bryce’s team installed Johns Manville blown in insulation in my Sunset garage ceiling and walked me through every step. The 365-day Done Right Promise is in writing and they honored a cosmetic fix on a vent cover two months after the job. I never had to argue. I just called, and it got fixed.”
Adriana H., Outer Sunset, San Francisco
Why Customers Trust Us
The pattern in these reviews isn’t accidental. Every job starts with a written price before a tool comes off the truck, so the number you approve is what you pay. Every tech is background checked and shows up in uniform, on time, in a scheduled window we actually keep. We install and remove insulation using products from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so you can research exactly what goes into your attic before saying yes. And every single job carries the 365-Day Done Right Promise: if the work fails within a full year, we return and make it right at no charge, with a free second visit if needed. That guarantee is in writing, every time, no exceptions. It’s how Alden Insulation has operated since 2002 as part of the Garrison Partners family, and it’s what The Garrison Code demands. If you want attic insulation, blown in insulation, or insulation removal in San Francisco, call (559) 245-9792 and talk to a live person. Get the written price, see the plan, and decide from there.
