EXCELLENT Based on 80 reviews Chip A2025-04-25Trustindex verifies that the original source of the review is Google. We contracted with On Time to have our blown-in cellulose insulation removed so we could install flooring in our attic. Marco did the initial visit and was very informative and gave several options and ideas for our attic in general (for the job, and for the future). The team that did the work was Nathan and Jack (spelling?) and they were great. Both were professional, respectful, and personable. I was expecting them to vacuum 80-90% of the cellulose off of the fiberglass below it, and it ended up being closer to 97-98%, including some difficult to reach areas. They had me do a quick check before they packed up, which I appreciated. I would definitely work with these guys again. The only feedback I have is that it was tough to nail down a date for the work and I had to follow-up a few times, but the job was done within 2 weeks of the estimate, which was totally reasonable.

We recently contracted On Time Insulation for insulating services in our new addition - the owner Marco was extremely professional, polite and courteous, walking my husband thru what to expect during the process of the job - the crew that came was very thorough, respectful of our property, and took the time to be sure there was complete coverage, of the high density spray foam insulation throughout the new addition - all in all we were extremely happy with the service, and final product - we highly recommend On Time Insulation Services, for all of your insulation needs Donal montero2025-02-26Trustindex verifies that the original source of the review is Google.

Michael Griffin2025-02-22Trustindex verifies that the original source of the review is Google. Our experience was great, they really went above and beyond. Very competitive pricing with a lot of added value from the other contractors. They managed everything with the project, and left our space cleaner than before they started. They provided innovative solutions to our insulation needs. Janice S. Muradali2025-02-13Trustindex verifies that the original source of the review is Google. Marco’s team was truly top notch! It’s so difficult to hire someone based on a Google search but I’m so happy it worked out so well. From the moment Marco shared his capabilities I felt confident to hire his team. For a reasonable extra fee they did a great job patching the holes. They cleaned up afterwards and the guys even mopped the floor. Ultimately the condo is warmer and the goal achieved! Jesse Beauregard2025-01-29Trustindex verifies that the original source of the review is Google. I reached out to a couple places for closed cell insulation to replace some existing fiberglass and go over some concrete walls in my basement and it was clear that this company was the ones to go with. Marco, the owner, was punctual, thoughtful and thorough with his quote. He worked with me on my vision for the project all the way through. When it came time to booking him, that was also easy. His team was polite and professional and the insulation application was extremely neat and tidy. In places where the foam would be visible we asked them to make it as wall-like as possible and they did exactly that. They left nothing behind and everything was organized and efficient. Highly recommend. JAMES BURTON2025-01-06Trustindex verifies that the original source of the review is Google. Very pleased, spray foamed my unheated basement in Hopkinton. The temperature in the basement went up 10 degrees a day later, without any heat. It will help keep out pest and nowhere for mice to hide. Price was very affordable. A great option if you wish to finish a basement area. Steve Munier2024-12-24Trustindex verifies that the original source of the review is Google. Marco and his Team did excellent work. They provided me with many options, great advice, and were very patient with me. Marco was very responsive and is a good communicator. They provided insulation removal service and spray foam installation. I highly recommend On Time Insulation for your needs. JP Vignone2024-12-18Trustindex verifies that the original source of the review is Google. Marco and his team were extremely responsive from the first time I contacted them for an estimate to the completion of the job. On Time’s employees were very respectful, neat and hardworking. I will absolutely use them for any insulation projects moving forward and would highly recommend them to anyone!
