“I've used SDI Insulation on 3 of my projects throughout the years... they never disappoint!
They're always on time, their work is superb and have never failed an inspection for their insulation work.
I'm in the custom home building industry and it's hard to find a reliable and professional insulation company in the Bay Area.
You get what you pay for and SDI is my go to company for quality insulation work.
I definitely recommend these guys!”
Mark Howser
“I have used SDI on multiple projects and have never had a problem. From spray foam in a bathroom in Tiburon to fiberglass batt insulation in a crawlspace in Mill Valley.”
Matthew Sturm
“On time and on schedule. Excellent service and willing to work with us regarding the pricing. Competitive and professional. Highly recommend. Pamela Martin was our sales person and she was enthusiastic about energy saving and creative with solving insulation problems/issues.”
Andrea Rush
“I am a general contractor and I have been using SDI for foam insulation installation for years. They are the best and we don't use anybody else. Foam is too hard to install and too easy to mess up so we goin with the guys who have the most experience.”

Rebecca Haskett
“Excellent job from start to finish. Our project manager, Dennis, did an excellent job addressing our concerns relative to noise and draft. We followed his advice and are completely satisfied with the results. The installation team consisted of 3 very capable and delightful young men who did a terrific job. The guys worked together very well, and they were polite and professional. The supervisor arrived to put the finishing touches on the job and the fellows cleaned up beautifully. I highly recommend SDI!”

“Excellent job.. I can’t say enough about this Company.

Great crew. They cleaned up perfectly. They sealed our attic with foam. Project manager even stop by to check on job. Job WELL done.”

“Wow! I have spent the last year doing a complete renovation of my home. Brett Delorenzi of SDI has guided me through this whole process of spray foam insulation, unventing my roof, and sound proofing my duplex. I do know a little about spray foam and Roxul insulation, but Brett literately took me to the next level on how Closed Cell Spay foam insulation and Roxul can work in concert. We did flash and batt in the laundry room, so no sound or cold comes into my upstairs apartment. Roxul (AFB) Acoustical Fire Board in the ceiling in the basement apartment to fire and sound separate the two apartments. We now have a very safe, very quiet, and warm duplex thanks to SDI!
The customer service has been phenomenal. Because of the rebuilding process I've had to reschedule my spray foam installation over six times. Marcella (i hope I am spelling it right) has be an absolute rock of understanding in scheduling my installations, so courteous. On the job site SDI employee's were super efficient, clean, and meticulous in getting that closed cell spray foam everywhere I had requested.
If you want insulation done right, this is the company you call in the Bay Area!"

“We discovered a bad rodent infestation in the crawl space and attic area of our new home. As a result, all insulation required removal and replacement. SDI held our hand thru the entire process. They provided 3 bid options, took care to ensure we understood each package/scope, and came out to meet with us for accuracy.
Once the project commenced, SDI was professional, punctual and incredibly efficient. The team would provide regular updates. We felt very well cared for and important as their client. It can be hard and stressful finding reliable and trustworthy vendors that aren’t over charging and/or cutting corners. Do your project right the first time with SDI. We had an amazing experience. Highly recommend!”
Anne Birdseye
“The workers arrived on time. They protected the carpet, doors, staircase carefully with thick plastic sheetings from damage by the big rubber hose. They sucked out the old insulation material from the attic completely and cleaned up the place nicely. Very polite and professional workers. I would recommend SDI to my friends.”
Thomas Lee

“Everyone at SDI - from the project managers, to the job managers, to the workers - was professional, courteous and just lovely to work with. We're so impressed with the efficiency of our heating system after reinsulating our attic and adding insulation to our walls that we wish we'd done this sooner! Highly worthwhile and recommended.”
