Client Testimonials

Thx for getting me in so quickly. Ryan was early which was great and did a fantastic job. He is definitely a dedicated employee and represents Kingston Spray Foam in a great and professional manner. I look fwd to using your services again and recommending your company to others.

Kingston Spray foam insulated my basement. Did a demolition of panelling and insulation from the 70’s. Very professional staff. Jeff spent an hour with me doing the consultation and going over my options. He was honest and didn’t try to sell me things I didn’t need. I got other prices but none as good as Kingston Spray foam. They also are very clean. No mess when they are done.

I would like to thank you, Jeff, for the money you and your great team have saved my partner and I down the road! You came to my partner’s house after one phone call and evaluated, quoted and spray insulated the problem areas that we had. The professionalism in you and your team really shows through , especially in your time scheduling, work and clean up when the job was done!! I can’t believe the difference in heating the house now, we had oil heaters going in both bedrooms before you insulated. WE HAD TO TURN THEM OFF AT NIGHT AS WE WERE TOO WARM! FIRST TIME EVER WHEN ITS COLD OUT!!

Your company and product are amazing! I can now relax in comfort and not have to wear sweaters because of the heat loss we had. With the rising cost of electricity I know we will be saving money as our furnace is forced air electric, which isn’t cheap to run!! So thank you for a great job and I will be telling all my friends about your company!!

Let me start with, I very rarely write reviews but felt I had to write this one… After almost a year of Renos and almost every trade working on my project, I have to say that the team at Kingston Spray Foam where the only ones who did what they said they would do at the price they said they would do it for and at the time they said they would do it. Thanks for being the one contractor who delivered on what we had agreed to. If your reading this and need insulation I would strongly suggest using these guys. Thanks

Our special thanks to Jeff & his team for the wonderful job they did on our house. Your people are very professional and hardworking, and the job was done exactly as specified and in the time frame as promised by you. Their diligence and dedication was demonstrated in the impeccable clean-up of the work site. We were very lucky that we came across your company and will recommend you to everybody that we know!

Jeff and his crew completed the spray foam application in the crawl space of the “green church.” I have used Kingston Spray Foam’s insulation services on a number of jobs in the past and continue to be impressed by Jeff’s attention to detail and knowledge. Hire the pros, as they say, and get it done right.

Had Jeff and his crew out to spray our basement and was in and out with the most professional team. Wouldn’t hesitate to tell anyone wanting foam work done to contact this Company.
