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!

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 cl

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

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.

The job was done on schedule, there was an issue where SDI contacted me to let me know that the job would be more than initially agreed upon as my home was larger than I had initially disclosed. They had never been to the job to measure up or look at the access. I sent them a PDF of our house plan that showed that my calculations were correct and they agreed to finish the job at no extra charge (which was nice of them, don't you think?). Ultimately, the job was done well and the price was fair

Had a great experience with SDI. As a homeowner, they made sure I understood everything, had transparent pricing and were professional easy to work with!

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.

Very satisfied with their work. The insulation we had them do was completed right and quickly. They were done within 3 days. We would recommend this company for all your needs.
