It has been a couple months now and we couldn't be happier! Sean and his team at Gateway Retrofoam delivered a fantastic product with great customer service, wonderful workmanship and a near spotless clean up! Our house has been quieter and our air conditioning is cycling less. Product performance as expected. The best part of having the home insulated was having a competent and reliable team on the job.

We had a difficult install: we have a very old home (123 years old), very tall (10 foot interior ceilings), and a lot of obstacles around the property. The team did an excellent job making me feel confident in their performance. They were all very knowledgeable, polite, and friendly. They went above and beyond! It's such a good feeling to have a team working on your property that outperformed your expectations. The true test of the product, though, will be this upcoming winter, and we will update our review. Thanks again to Sean And his team at Gateway Retrofoam!

Shawn and his crew are amazing! They kept me in the know from start to finish, and to say they were professional would be an understatement. The noise from the outside of house has ceased and my house is already feeling the benefits from the thermal aspect. I would have given more than five stars on google reviews if it was possible!

Our brand new, oversized furnace and AC were not keeping the house at set temp. We did not want to remove siding or drywall at this point, and decided Gateway Retrofoam was our best option. It has been only a few days, but I can tell you that our house has been consistently on the temp it is set. The AC is cycling like it should. And the noise from the roadway has virtually disappeared. Very Happy Customers!

The owner Shawn and his crew showed up on time, got straight to work and finished my installation in less than 1 day from start to finish. They cleaned up after themselves and were courteous and polite. I instantly noticed that my home was quieter because I could no longer hear some of the outside noise. Shawn informed me that I'll notice improved comfort in the coming days when the summer heat kicks in. I highly recommend Gateway RetroFoam if you want high quality foam insulation in your walls without the mess and expense of removing drywall.

Shawn and the crew arrived on time and got straight to work. The installation of my new insulation was quick and as advertised. They cleaned up like they had never been here. I immediately noticed a big reduction in noise and my first power bill was a little over 30% less! Highly recommend these guys you can't go wrong. Great product great people.

Absolutely wonderful crew and very knowledgeable. The results are almost instantaneous. I could feel the results as soon as I reentered my home. No more drafts or "cold spots". Can finally enjoy my living room without needing to bundle up. Highly recommend this service, especially to anyone who has a slightly older home.

We had installation of Gateway RetroFoam Yesterday 4/19/2022. They were Very Professional before, during, and after installing the foam, also answered any questions, gave my husband a tour with explaining all the steps along the way. We felt immediate relief of the cool draft through the house, also noises outside were greatly muffled, we look forward to lower utility bills. This insulation is really remarkable, why have we not heard of this before now. Lol. Please call and talk with Shawn Bruce, owner/operator, soon you won't be disappointed.

Service performed: Exterior Injection Foam Insulation. I can't thank Gateway RetroFoam enough for the incredible service. Shawn Bruce and his team are awesome. Very professional and friendly. They all went above and beyond. I appreciate how they were very helpful and knowledgeable. I'm very impressed with the process and product. Within hours I felt a difference.

I didn't feel the drafts. The temperature of my home feels different. And my home actually feels cozy. I'm am totally grateful. So glad I made the decision and I highly recommend Gateway RetroFoam.

We are very pleased with Gateway RetroFoam. We have noticed a change in the temperature inside our home. I don't feel anymore drafts in the house. The kitchen, bedrooms, bathroom is a big improvement. We even noticed the basement is warmer. Shawn and his crew cleaned up everything and put stuff in it's original place. All we can say is Wow what a big difference. We highly recommend. Don Broyles
