He said his dad would email the quote. I texted the owner and gave my email. He responded with a thumbs up emoji. I didn't get anything that day or the next. So on the third day I texted again and said please text me when you send the quote as sometimes it goes to my junk mail and I didn't want to miss it. No response. A couple of days later I tried calling, left a message, no response. The following Monday still nothing so called again and still nothing. They just ghosted me. Very frustrating as I wasted a week waiting for this and could have had another company come out and do it.

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.

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.

When we finally approved the estimate and scheduled the appointment, Max's team came and finished the job as promised. 911 Attic Insulation's quote was also the most competitive out of the 4 we received. I would not hesitate to recommend 911 Attic Insulation to anyone who is looking to replace their insulation.
