I had Keith insulate my home about a year ago and it was fantastic. The insulation is not cheep but he was excellent to deal with, did a fantastic job and the quality of the material is well worth it. The home is significantly more comfortable, has no air leaks, seems to be generally more rigid and it has a far better R value per inch than other solutions I considered. I am confident this is the best way to have insulated my home and will save money in the long run.

The Neeco Crew 4 - JR, Juan and Ismael had worked the last day 2 days at our Scituate, MA home insulating the attic with duct sealing, propavent, added 6 inch fiberglass batting. They also took care of our attic door in our room over garage with 2 inch thermal barrier and the kneewall with 2 inch thermal barrier as well. Sealed gaps in the bedroom with dormers in the small closets. Crew 4 took care of adding a bath fan hose and a new attic stair cover. They also took care of the exterior doors with free weatherstripping. The energy savings are real even with our 15 year home we built. This crew was professional and experienced in this type of work. Very grateful for the work they did. I recommend them to any homeowner. This will save us $ during the winter and summer for sure. Greatly appreciated!
After the energy assessment gained from Mass Save, my partner and I decided to change some major home appliances like AC, water heaters, Inductions stove from them to reduce energy use. We got rebates and were grateful!
Paul Tavares did an amazing job throughout the entire project me……me and my husband were really impressed by not only his service, but by his knowledge and thoroughness….. Anytime we had a question or there was a concern throughout the entire project. He was always time when you go with his responses and help guide us through the entire process. We really appreciate having him on the team and can’t stop singing his praises. My husband is the one who actually told me to give him a shout out on your reviews.

I hired OnTime Insulation to spray the inside of my metal garage. They sprayed 2" of closed cell insulation. I received 3 quotes from 3 different insulation companies and they were all close in price. OnTime was the lowest estimate by about $150. They were pleasant, flexible, and did top quality work (see photos). I would highly recommend them and if I ever need insulation again in the future, I will call them first.
Marco and his team helped me in a pinch on short notice and accommodated a time sensitive insulation project. The guys who did the work, were kind and professional, and worked incredibly hard in unseasonably hot temps to get the job done. All while doing it, after there day had already been completed. The only constructive criticism I would provide is— initial communications via email were a bit ambiguous. While Marco and the team made it work, there were duplicative email threads that had different answers and when I was triple confirming date and them, there was no response and I had to call Marco directly. Ultimately, it worked out and I’m grateful for the team but it made the scheduling more stressful than it needed to be. Overall the work was great and the team too, insulation was done well and that’s what matters.
Stellar work from the start with the estimate and options: Marcos provided the best options and worked within my budget. Then came the crew who worked for 2 days, did a fantastic job, and cleaned up. I have had problems with contractors doing poor work and/or running with my money. You can trust OnTime insulation for a job well done.
