    The size of the holes - they are filled with spackle
    Kristin O.

    Highly recommend. Years ago we had SDI remove some asbestos in our home and they did a fine job. Recently, we contacted them for wall insulation (blow in). Kyle came out to estimate and later Dennis helped with a few additional questions. We are beyond happy with the results! Our home is quieter (we live near the flight path for SFO) and stays cooler in the Summer and keeps the heat in the cold. Our only regret is that we didn't do it sooner. We were aware we would be left with the painting to do so our painter is on his way to texture and paint. This was so much more cost effective than doing this project from the outside (siding removal). Great experience and good customer service.

    They said they would start the job at 8am. They were parked outside prepping at 7:30am both days. Amazing.

    These guys are as perfect as the last time I used them for my other home. I bought this house in July, and Jack came out and looked at how bad the insulation was. In my last house, we sprayed foamed the entire attic, making it a warm, conditioned space. However, my budget is hitting differently now. So Air Sealing and Blown in Fiberglass for me. Due to even more budget constraints, I had to wait until December to get it done. Jack was on vacation, but Brett (who I worked with previously) stepped right in when I called. They had the job on the calendar in a week, and it was a two-day job. Alfredo answered all my questions and was accommodating when I requested a different material be used in the attic. The guys who came were courteous and efficient. They put a fresh tarp on my floor each day and left no trace. I am a fan of SDI because they don't try to sell you; they make suggestions that work best for your home and budget. I couldn't be more pleased and can already feel the heat staying in my house longer. Now it's time for those windows to be replaced. Thank you again, SDI, and keep up your high-quality work.

    Fireplace insert

    We had a gas insert fireplace installation from SDI Fireplaces and we couldn't be happier. The 2 installers were professional, courteous, and answered every question we posed. They cleaned up everything before and after installation, and took as much time as we needed to explain its use. We highly recommend Joe E and his team at SDI.

They sent someone the next morning for an assessment and got us scheduled right away! In the interim, they gave us recommendations to deter the rats, which worked. Carlos and his crew arrived on time and finished quickly. The price was reasonable (honestly, on the cheaper side yet the quality and professionalism was great!). There was an issue with a short circuit because a rat chewed through the insulation that we didn't notice until the weekend, but Carlos responded immediately and came over to fix the issue. We are so grateful to Carlos and the Attic Crew for helping us with rats in the home, helping us feel more confident about keeping them out for the foreseeable years, and for all of their professionalism, knowledge, and expertise! Would definitely recommend!

The communication was excellent, even on a holiday weekend I got called back within an hour of reaching out with questions, which I certainly did not expect! They arrived promptly for appointments and were thoughtful about avoiding tracking dirt into our home. They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space. I could not be happier with my choice to hire them, and plan to work with them again when I'm ready to replace my attic insulation.

    We had rodents dancing above our heads at night in our low head-room attic. We called Attic Pros…read morewho did a cursory "inspection" and recommended complete replacement of attic insulation, replacement of most A/C duct work in the crawl space below the house, sanitizing, and sealing up "all" entry points for critters. It was very expensive but we went with them mainly because the "inspector" (a salesman through and through) had excellent English and promised to personally manage the project. He answered one subsequent question and then disappeared, never to be heard from again. The estimated 3-day job took 3 weeks, with schedules shifting daily, different crews, minimal work days, redundant and often incorrect communication via text and email, and no explanations of what was going on. The crews were friendly but spoke minimal English. It was difficult to understand what was done, not yet done, or not intended to be done. Once they left, the critters remained. Staff came back 3 or 4 times to seal additional openings ... to the wrong area (crawl space rather than attic). The most recent visit by Jorge was very good. He had good English so his explanations were understandable and helpful. He found and fixed two more openings - these at roof level - and recommended a spray that can repel rodents from returning. I bought and used that (why don't they do that themselves?) and the first night at least was the first "quiet" night in months.

    Great experience--highly recommend!…read more We reached out to EM along with a couple of other companies to inspect our attic and crawl space, and they were the clear winner. We wanted to replace our old insulation because of rat droppings and also improve the temperature difference between our first and second floors, since our upstairs would get much hotter during the summer. Sebastian performed the inspection and was our main point of contact throughout the project. He was thorough, knowledgeable, professional, and easy to work with. The estimate was very fair, and he took the time to answer all of our questions without any pressure. We ended up replacing all of our attic insulation, installing a radiant barrier, replacing some of the ductwork, and adding a moisture barrier in the crawl space. On the day of the installation, a large crew arrived right on time. They did an excellent job protecting our home and keeping everything clean while they worked, and they completed the entire project in a single day. It's been about a month since the work was finished, and we've definitely noticed a difference. Our upstairs no longer gets nearly as hot as it used to, the house holds its temperature better, and our AC seems to run more efficiently. Overall, we had a fantastic experience from start to finish and wouldn't hesitate to recommend EM to anyone looking for attic or crawl space insulation work.
