    Let me begin by saying that Ryan and his crew are extremely trustworthy and professional. I am an…read morearchitect and well-versed in air sealing, but I did not have personal experience with removing old fiberglass batt insulation and installing only two inches of closed-cell insulation. In our 1868 Victorian home, Ryan and his crew removed all of the old fiberglass insulation from remodels we'd done over the years and installed closed-cell insulation in the attic ceilings and floor. I'll admit that when I saw the large amounts of old insulation being removed, I seriously wondered if I had made the right decision. Rather than jumping to conclusions, I waited until I could compare our December 2024 PG&E gas bill with our December 2025 bill. Since we heat our home with a gas furnace, my focus was on gas usage rather than electricity. In December 2024, our house was cold--uncomfortably so. The furnace cycled on and off constantly throughout the day, and we experienced significant temperature swings. The old insulation simply could not hold heat. Fast forward to December 2025. While our gas usage in therms was similar, the outcome could not have been more different. Our home is now warm and comfortable. We keep the thermostat at about 72 degrees during the day, and at night we set it to 62--yet the temperature holds steady around 66 degrees all night. In other words, the heater doesn't even come on after we go to bed. The result is a dramatically more comfortable home with no increase in gas usage. I expected our December 2025 bill to be through the roof, but instead it remained essentially the same--with vastly better performance and comfort. I couldn't be happier with the results. I'm so glad I put my trust in Ryan. We finally have a warm home during the coldest month of the year, and going forward we will be using less therms per month.

    Great great service the technician Jose Duarte was very professional and went above and beyond I…read morerecommend this company 100/100 there prices are unbelievable and so affordable and very professional company, affordable, and dependable will not use any other company, but this one

    When we bought our house many years ago I discovered a thin layer of blown in cellulose insulation…read morein the attic. It wasn't very even and being a bit of a handy man I added fiberglass batts over top. That made our house more comfortable. But since then we've had a couple of remodels, new roof, etc. In recent summers we noticed that the skylights in our house were much hotter than we remembered them being so one day I climbed up in the attic and saw that some areas had no insulation while others had far more than was needed. We decided we needed to have the insulation "fixed" - whatever was needed. A few weeks ago I called OJ Insulation in Morgan Hill. One of their estimators replied with a time to come by and we soon had an estimate. He agreed that we had plenty of insulation and it just needed to be "touched up"- which meant the guys would rearrange existing fiberglass to fill holes, put more strapping to hold batts thad shifted (like the skylight tunnels), etc. It wasn't practical to walk the entire attic to see exactly what was needed, so he gave me an estimate based on the living space - about $1/sq. ft. We got a time slot a few days later and on the morning a two man team showed up a few minutes early. They confirmed what I had asked to be done and they got to work. They took before and after photos which is helpful. They cleaned up and left the area spotless. It's been a couple of weeks since and we've had some hot days and I'm happy to report that there are NO hot spots in my house any more. Good job guys! Remember the estimate based on square footage? The estimator thought it would take the team 3-4 hours of work and I signed a contract of that amount of work. However, the guys were able to finish in about half that amount of time. I mentioned this to the estimator via email afterwards. He was surprised but gave me a discount on the price. I was pleased. On the basis of good work by their team and honest dealings by the management I am happy to recommend OJ Insulation.

    They did an amazing job. Came to quote within 24hrs of me calling. They had the job done in a…read morecouple days and I couldn't be more impressed with the quality. They are very professional and have a great team. They definitely know what they are doing. I highly recommend them for any of your insulation needs. I will be having them come back to do the garage next.

    Very professional crew and competitive pricing! They showed up on time, were courteous,…read morecommunicated well and took care of business all day aside from lunch break. They sealed many difficult to reach spots in the attic, eves, roof returns etc. and around the crawl space and around pipes, with 1/4" galvanized steel mesh (sometimes added concrete where needed). They produced before and after pictures of their work and set a bunch of traps that they will check in two weeks. I was pleased.

    I contacted several attic and rodent companies before choosing Attical, and I'm very glad I went…read morewith them. What stood out most was how thorough they were. Unlike some other companies that focused only on the attic, Attical inspected the entire property, including the attic, crawlspace, garage, exterior walls, roofline, and other potential rodent entry points. They identified and sealed areas that other companies either overlooked or never mentioned. Their pricing was also very competitive. During the quoting process, some companies adjusted their pricing based on estimated labor time, crew size, or changing measurements. Attical, on the other hand, honored their proposal and focused on getting the job done properly rather than finding reasons to increase the price later. Throughout the project, they delivered exactly what they promised: insulation removal, sanitation, rodent proofing, air sealing, duct repairs, trap monitoring, and new insulation installation. The crew was professional, hardworking, and took the time to explain the process and answer questions along the way. Overall, I felt that they genuinely cared about solving the problem correctly instead of simply completing another job. I would highly recommend Attical to anyone looking for attic insulation, rodent proofing, or attic restoration services.
