Sdi Insulation Inc

SDI Insulation Inc runs insulation work from Burlingame for homes and businesses across the Bay Area. The company takes on residential projects, new construction, remodels and commercial jobs with spray foam, blown-in and batt insulation plus fireplace installations.

Homeowners bring them in for attic reinsulation, wall fills to stop drafts and noise, crawl space cleanouts after rodent damage, and soundproofing between floors or units. Sergio and his team insulated attics and master bedrooms while shifting furniture back and leaving the place clean. Dennis served as project manager on noise and draft fixes, while Brett Delorenzi led spray foam and Roxul installs on renovation jobs. Pamela Martin handled sales and worked out pricing on energy-saving solutions. Crews also tackled ADU insulation and bathroom foam work without missing inspections.

They arrive on schedule, protect floors and stairs with plastic, give updates during the job and finish on time. Reviewers note competitive bids with clear options explained ahead, straight communication and no surprise markups once the scope is set. The same teams cover San Francisco, Tiburon and Mill Valley, working on everything from small residential fixes to larger commercial envelopes.

The Google rating sits at 4.8 with consistent notes on crews that stay professional, keep sites tidy and deliver reliable results that hold up. General contractors return for foam work because the installs pass checks and improve comfort fast.

“Sergio and his team did an excellent job insulating my attic and the walls in my Master Bedroom. They were very professional and extremely polite. They even helped me move my furniture back into place, when they were done. They left my home spotless. And I must say from Joe, who came and gave me an estimate for the job to the office staff, everyone was very helpful. I would highly recommend them to anyone who is thinking of having their home insulated.”

“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!”

“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!”

“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!”

“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.”

“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.”

“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.”

“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.”

“To whom it may concern , The workers were great and did a good job.The over all unit is much quieter so the goal was accomplished. There was three issues that cost the building owner because SDI was not fully prepared for the situation.The issues we informed both of the sales associates ahead. of time and if you work in SF these issues should be resolved ahead of time. 1.The material estimate was substantially off. Yes a judgment call, but I told the appropriate person ahead of time that the building was made 140 years ago with real 2X4's and 2X12's, not modern 2X4's and 2X10's. Hence the wall and floor cavities were sometimes 2 inches deeper than would be on a more modern building.Simple math miscalculation. 2.The open truck was a big issue on a street with lots of foot traffic. We had to provide security for when no one was at the truck. 3.The parking we had to provide cost us lots of bucks. Work these out and would consider using you in the future. Thank you David Tejeda”

“Great experience with SDI Insulation. They did their job fast, communicated well - everything is very straight forward. The prices are also competitive. Thank you Dennis and the crew for the quality job!”

“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.”

“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! Thank you so much!”

“We hired SDI to insulate our ADU. They were on time, professional, and very easy to work with! I highly recommend SDI Insulation!”

“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.”

“SDI did the spray foam closed cell R38 in my attic. Very reliable, professional and organized operations.”

“SDI insulated my house and I couldn’t be happier with the work they did. Much cooler on hot days and very professional crew.”

“It was a great experience. The crew showed up on time and completed the work just like they said they would. Very professional, would definitely use them again.”

“Professional, quick, clean and on time. I'm a fan. Good job SDI. We'll use your services again.”

“Nailed it! Fantastic workers. VERY reasonable pricing. Best experience I've had with a contractor of any sort in San Francisco in 12 years.”
