Review 1
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!

Review 2
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!
