My service request entailed having to deal with uncooperative bossy tenants and Johnson's team was always professional, courteous, and helpful. They communicated with me and got the job done in a timely manner with excellence! My entire attic was cleaned, sanitized and insulation was installed. Rodent proofing was done as well! I wouldn't have chose anyone else. The value and customer service is beyond what I asked for! Do not look anywhere else! read more

They installed a Bosch heat pump system for my two level home last year. This year there was an issue with one of the unit's thermostat. It turned out to be some minor wiring issue. They promptly sent a technician out yesterday and today to locate and resolve the issue very quickly. Miquan is very professional, courteous and would definitely do business with them in the future and highly recommend them read more

Good price, done quickly, neatly and right. Our attic was bare after we purchased our home. All the quotes we were provided were double what we paid. Needless to say, we spent a hit summer and cold winter with no installation. Being a new homeowner we are on a tight budget and grateful we came across this company. Looking forward to being comfortable in my own home. They are able to accommodate different schedules. Very responsive! Best price around! read more

Great responsive service. Attentive to our requirements and requests for a free inspection after completing the attic work.

Huge shoutout to Johnson's Insulation for a job well done. Miquan made the planning phase seamless, and Oscar's team handled the implementation with ease--even with some last-minute changes. If you need insulation work done by people who actually follow through, this is the team to call. read more

I used Johnson's Insulation to do blow-in insulation in my walls. Miquan was on-time for the estimate and answered all my questions. We were able to schedule the work within a few days and it was a one-day job as promised. I was surprised at how clean my house was left after the crew was done. I was also impressed with how smoothly the walls were patched, they were truly ready to be repainted with no other prep needed. Looking forward to using this company again in the future when I need to insulate my attic. read more

Their service and customer focus is top notch. I had used them 3 times for different insulation services. Each time they were on time, very professional, clean work and detailed proof of work. read more

Johnson's Insulation helped do all of our crawl space and interior insulation. They did a great job, were friendly, and efficient with the work! read more

This review is overdue as I got my insulation done back in June. Anyway, Miquan (the project manager) was very responsive and his bid was very competitive with the other bids I got. One of Johnson's benefit is that they are Bayren contractor and I was able to get a 1500 dollar rebate. Just to note, not all insulation contractors are Bayren approved. They insulated my attic and walls in under a day. There was a slight mishap during the installation but Miquan got on it immediately and resolved the issue same day. I'd totally recommend Johnson's Insulation! read more

Had an initial bidding problem. Turns out that they had the wrong email noted. Bid came detailed and we are considering. Work has not been done. This review is just on the process and time it took to get everything worked out. Running a business is not easy! read more

Great experience with this well managed Company. They performed quality work for a very competitive price. Their owner is hands on and closely monitors the work. read more

Miquan from Johnson's insulation provided a thorough and honest assessment, clearly explaining the scope of work, material options, and expected costs. There were no hidden fees or surprises, just a transparent breakdown of what needed to be done. The crew arrived on time and worked efficiently, removing the existing insulation with care and meticulously cleaning up the debris. They were courteous and informative throughout the process, answering any questions I had along the way. They did a great job of rodent proofing and installing the new insulation. They also helped me rodent proof crawlspace with new mesh netting. They tidied up their work and left my house clean. Overall they did a great job and I wouldn't hesitate to recommend them to anyone! read more

Johnson helped me understand the insulation needs at my home clearly stating what is needed and what is not. I highly recommend his company. read more

I would highly recommend Johnson Insulation! They recently completed a large project for me. They replaced the old mice infested insulation in my attic cleaned, sanitized and rodent proofed it. As well as installed new insulation in the crawl space! It was refreshing to work with a contractor who is honest and straightforward in their pricing and works with integrity! He even worked with me on the time frame to do both the attic and the crawl space at different times to allow for other work to be completed! All of the workers were courteous and hardworking . They cleaned up after themselves and removed their own garbage. On site, on time everyday! A special thanks goes out to Guillermo for having my back when it came to the duct work that needed repair/replacing in my crawl space. You saved me from being taken advantage of! read more

Competitive pricing, professional team and on time execution. I had both attic and crawl space insulation replaced, the team executed as planned. I highly recommend them. read more

We had our home attic insulation replaced by Johnson Insulation in August 2023. We have about 2100 square feet of attic space that was insulated by Johnson Insulation. Miquan and his team did a great job. We are very happy with the work they did. The insulation of the home has also improved significantly after the new insulation. Miquan is very easy to communicate with. He is very responsive to any questions or queries. It was a pleasure working with Miquan. He explained us the types of insulation and helped us choose the right insulation for our needs. The price quoted and charged by Johnson Insulation was also very reasonable and competitive. The crew covered all the area before starting the work and cleaned up every day after work. They made sure that electric and cooling system in the attic was well take care of and not damaged during the installation process. We are very happy with the work. We will recommend Johnson's insulation to all our family and friends. read more

I called this place to schedule an energy audit (I specified that over the phone) which was set for today between 9am-11am. I got a text at 11am saying that they were running behind schedule and that they'd see me "shortly". An ETA would have been helpful. Miquan showed up at 11:40, no apology whatsoever for being late, no friendly conversation made on the walk to the door. He comes in, asks no questions of me about our issue, knocks on two walls and says we don't have insulation and that's our issue. We do have insulation (I have tested it through the outlets). He was out the door within two minutes. Super duper disappointed and aggravated that I waited around for a late appointment and zero insights. When I called Miquan and expressed my disappointment, he said that an energy audit is charged and is different than what was scheduled. I would have happily paid but was never told that I wouldn't be getting an energy audit done in the first place. He offered a complimentary infrared camera inspection "the next time we're in the area". Go elsewhere, PLEASE. This place is a waste of time and doesn't know how to respect customers. read more

I generously give 2 stars, only because had I actually had the opportunity to hire the company, I imagine they probably would've done a good job. I was given a 2 hour window for an estimate - Miguan, the owner showed up a half hour past the window. Very informative & professional, once he showed up. Before he left, I confirmed he had my correct email address to be sure I received his estimate. After a few days of no estimate, I called the office to remind them. An operator transferred me to someone who assured me that I'd receive my estimate in the next few days. A week later, still no estimate so I repeated the phone call - same routine & story, and after 3 weeks, still no estimate. No biggie - in 1 weeks time, another company gave me a written estimate, provided references & scheduled an appointment & are currently in my driveway finishing the job. read more

Johnson's did our attic insulation. The work is nicely done with R49 insulation bats. Oscar and his guy are the actual installer. They worked diligently for an entire day to remove all the old insulation, cleaned rodent waste, and sanitized the attics. They came at another day to put in new insulation which made a difference immediately. Miquan was very knowledgeable about the Bayren rebate program and he visited our house during the project to make sure everything goes well. They are very reliable and provide great customer service. read more

Miquan came to our home to evaluate the work involved, gave an estimate by end of the day.

Excellent communication & he has got an excellent team who did a clean job ; would certainly recommend. read more

Miquan and his team helped with attic insulation . Thank you Miquan for quickly setting up installation and inspection with Bayren .Fair priced for R49 insulation that comes with rebates read more

I'm an independent inspector for various Bay Area rebate programs, inspecting hundreds of projects per year required for rebates. Johnson insulation has consistently stood out above the rest with their quality insulation installations. Very pleased to say that 100 percent of their projects have exceeded BPI quality requirement. Most of the projects I see are R49 batt installations which have been even and continues with no eave vents blocked. Never a missed attic hatch insulated. On the blown in projects the attic rulers have always been placed every 300 sf as they should be for quality control. Keep up the good work, you make my job easy. read more

Miquan and his team are great! We saw their car on the freeway, and after checking out their diamond reviews, called to add blown insulation in our tight attic space. They are on it! He is extremely responsive, the team was punctual and knowledgeable, and I couldn't be happier! I can't say enough good things about our experience. read more

I Met With Miquan And Initial Estimate was good He conducted Thorough Inspection And His Crew That Came Out Very Efficient & Hard working Price Is Definitely Fair For Peace Of Mind I Am Very Happy With The Work From Beginning To The End Also The Follow Up Was Priceless Thanks Again Well Done read more

Maquan came out immediately to give us an estimate. Very nice, personable guy who knew exactly what we needed. He seemed interested in the work at the time, though we knew the product we wanted was hard to come by because of Covid and the Texas freeze. On the phone he said he emailed a bid which I never received. Didn't get anything at other email addresses or text numbers I gave him. I asked for some kind of response or rejection of the project but never heard from him again. So annoying. read more

I was working with Bats with a vapor barrier that didn't fit my insulation situation (cathedral ceilings). Miquan came same day for a quote and then the next day to spray in foam. Luis masterfully maneuvered the truck down our narrow steep street and was timely. The crew was super knowledgeable and friendly. They took care of us in a day and even came back the following day to check in that all went well. Great experience, would recommend. read more

Johnson's did incredible work. In less than a week, we went from zero insulation in a messy attic to R38 installed at a much lower price than we expected and on-quote. The owner came by the next day to verify everything was done properly, too. We'd recommend them to anyone. read more

Miquan Johnson contacted for my post related to rodent control. He came on time as promised and gave me a quote which was reasonable, though he gave me a month warranty for his work, when I requested him for a 6 month warranty he agreed. He came on time and finished the job on time as per the discussion. He did the job well and I hope my home is completely rodent proof now. He certainly deserves 5 star rating. read more

They came in on Saturday and finish the 1st job and per my request for additional work , they came in Sunday as well. I will use their services for all my energy savings needs in future. read more

I'm leaving my second review for this company. I've had positive experiences both times I've used this service. Even if the first round of closing off entries does not fully take, Johnson's is willing to guarantee their work and come back out free of charge to complete a second round of inspections. The scheduling was easy, the work was done well and the staff is very easy to work with. A+ service. Would work with again. read more
