We used On time Insulation to fully spray foam our horse barn while renovating. Marco showed up promptly for the initial estimate appointment, provided us with multiple options to fit our budget, and had the breakdown ready in a week. Full install and clean up was a little over two and a half days worth of work, and we couldn't be happier! Great work, excellent communication and follow through. Already recommended their services to our neighbors!

Professional, communicative, and on time! Highly recommend Marco and his crew.
The scope of work included closed cell foam spray in my attic and in my basement. I was very concerned about odor from the foam because I’m quite sensitive to smells, but when I walked into my home there was minimal odor. My attic has windows and basement a door, so they offered good ventilation. Marco assured me the smell would be minimal, and he wasn’t lying.
Marco communicated via phone and text every step of the way from consultation to scheduling, and through completion of the project. He is knowledgeable, professional, and courteous.
The crew who performed the work went above and beyond. They prepped the basement with care draping everything I had moved away from the walls, pulled up all of the rugs they would be walking over throughout the home, and cleaned up very nicely. You don’t always get contractors who do that, so they stand out.
All and all, I’m adding my experience to the 5 star rating. Very pleased.

Extremely professional, one of the best experiences I’ve had with a paid service. The workers were friendly knowledgeable and efficient. They showed up when they said they were going to show up and they completed the job before they left. Very happy with the service.

Very professional guys, job well done. Immediate improvement on heating a single family home. Difference is day and night compared to bare attic

With winter fast approaching we were anxious to get our attic insulated ASAP. Marco's team worked on Sunday to fit us in. Unlike the company who did my daughters house and underfilled her bays with closed cell, Marco gave us thicker than contracted layers, thoroughly protected floors/outlets etc and cleaned up afterwards. Totally professional job!

I’m happy with my experience working with Marco to have spray foam insulation applied to a framed room in my house. Marco and his associate Francer were polite and professional and left the room in a clean and orderly condition. I’m happy to recommend Marco.
