Get matched with top blown in insulation install or upgrade pros in Castro Valley, CA

"Had a great experience hiring Bay Valley Insulation. The quote arrived very efficiently and was the price I was looking for. The crew of Tony and Henry arrived inside the scheduled window and work was completed in a timely manner that day. The job looked great in the blown attic and final clean-up was great. Thank you."

"We needed retrofit wall insulation and after checking around all the listings through AngiesList, Yelp, and others, we found that only Bay Valley and SDI does retrofit wall insulation work. We went with Bay Valley because the price was reasonable and they responded quickly and promptly (can't say this about SDI*). Joel was our estimator and he came out promptly at the time and date indicated. He was thorough and thoughtful on how he approached the job, not overselling or recommending things we didn't need. We live in an older house and he appreciated the home and looked for the most non-invasive method to take care of our un-insulated exterior walls. Bay Valley's approach is to come in from the exterior walls with the typical 2-hole process (high/low) to blow in the cellulose insulation. They sent two guys in and despite a couple snags in the job, they finished the job in one full day. Afterwards, they plugged the holes, textured and primed, and the next day came in to paint (our-supplied) paint. I was really amazed how well and seamless it all looked afterwards. They did a good job cleaning and even moved the cabinets in the garage back where they originally were. The real result? The mornings have been a little bit warmer than last week, but so far the heater has barely turned on over the past couple days. The house already feels warmed and less temperature fluctuations. We already got brand-new attic insulation last Fall, but the wall insulation really did the trick. A definite recommend to anyone who needs a good team to do insulation in their home. * dealing with SDI was a nightmare, unfortunately. With *several* calls about being in the ER, then lots of other excuses, it just didn't seem like they wanted to do the job or something. I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done. sigh."

"Ahmad from GreenShield is very professional and provides excellent customer service. I was looking for a company to finish my insulation project as I had to fire Attic City for their poor customer service and terrible rodent proofing. Ahmad was extremely helpful in connecting me with another rodent company and also helped me find another company to install new ducts. Ahmad followed up with me regularly and informed me of a rebate program for the insulation and duct work. I am super grateful for Ahmadâ s help and I highly recommend GreenShield. If I could give more stars I would!"

"Working with Vortex was a great experience. The crew was totally professional and very experienced and did an excellent job spraying closed cell insulation in the new addition to our house. When they were done the job site was left totally spotless. Their prices are very reasonable/competitive. We are very pleased with the work they did and how easy it was to work with them. We will certainly use them again in the future."

"Melesio and his team did an excellent job removing old insulation/cleaning, rodent proofing/sealing, and installing new insulation all in one day."

"Atticare came an "vacuumed" out he old blown in insulation, closed up the holes to the outside and installed new insulation. They were prompt, worked cleanly, told us what they were doing and gave us pictures of the completed work."

"I obtained 3 bids via Home Advisor and 3 different companies showed up to quote it. As price went, Attic Elite was the middle of 3 bids, but I was the most impressed with the professionalism of the Attic Elite rep of the 3 who showed up. And Attic Elite provided the written bid electronically within a few minutes of leaving my home. I waited almost a week from another vendor and 2 days for the other one. Neither of the other 2 offered vacuuming, disinfecting, and deodorizing of my attic space. Neither of the others offered patching of holes for rodent infestation. I feel I got way more value from Attic Elite as compared with either the higher or lower other bids. As far as the work went, it was better than expected. They did insulation batts in the lower crawl space. Insulation batts in the ceiling and blown in to all of our (mostly stucco) exterior walls. After those hole patches in the stucco were done by Attic Elite, it was hardly noticeable other than needing paint. Here's what was beyond what I expected. My attic was full of 50+ boxes of stored items. I didn't need to remove them. They took care of it and neatly stacked them in my garage! Theyfoam sealed everywhere that vertical sheetrock met horizontal and anywhere there were gaps of any kind. That's something I wouldn't have thought of. They replaced damaged vent screens that had holes and foam sealed around them. They cleaned up after themselves like they were never there. From initial quote visit to when they were done, they were polite, professional, clean and thorough. No high pressure sale. They were done in less than 2 days. They had a standard price list and it was what it was, and they showed pictures of how they do what they do at the time they quote it. And provided pictures of every area as they completed each portion. As to what I had done, I'm really happy with it. Sure I didn't like spending the money, but my heater was running constantly before in the winter and the ac running all summer. We could always feel a breeze in the house if it was the least bit cold outside. Our hvac was always running resulting in high gas and electric bills. By the end of day 1, the ceiling and crawl space insulation was in and we already felt a huge difference and the heater wasn't running nearly as much. After the blown in walls were done on day 2, our heater was almost never running. Mind you, it was done in February and really cold outside. Since the install, we're leaving the heater mostly in the off position. What a huge difference. I'm not one to write reviews. But I wanted to take the time to write this one. I've already recommended Attic Elite to my neighbor and won't hesitate to recommend them in the future. Outstanding job. Worth the money. Highly professional. You can't ask for more than that."

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."
