RetroFoam was great. Two different teams to insulate my 100+ year old home. They were efficient, polite and organized. Very friendly & approachable. Thanks to Mike, James, Mason & Scott who climbed under my 3 season room to spray foam (I couldn't face those spiders!). Thanks to Zach, Cade, Felix, Cisco & Rob who spent hours getting foam into my walls and cleaning up beautifully! Great job guys!

The crew did an excellent job, and my wife can find fault with anything because she has high expectations on workmanship, she said she would give them more than 5 star. The crew was extremely polite and respectful and did an excellent job on clean up after insulating my whole house.

We had Ken and his crew insulate our entire home. They were very efficient and did a great job. We discovered a good chunk of our home had no insulation in it! So glad we had this done. We could instantly tell the difference and has also reduced noise from outside. Thanks again Ken and keep up the great work.

100% Recommend! My husband and I moved into our home during the winter months and noticed the heat wasn’t staying inside and the furnace seemed to constantly be running. On day 1 we got our then current, poorly installed insulation taken out from the attic. Day 2 they spray foamed the attic and on day 3 we got our exterior spray foamed, as well. Already, we have noticed our air conditioning running far, far less, our house is quieter and we didn’t even notice that the neighbors had people over until we looked outside.

Erik and the team were great. Erik made the initial visit and quoting process easy. It is now the middle of the winter and we are seeing great results from having RetroFoam insulation in our walls. Couldn’t be happier!

Retrofoam reinsulated our 120+ year old farmhouse and it's made a huge difference! Our energy bill is already lower and our entire house is more comfortable. They did the whole job in one day, our siding looks untouched, and they cleaned up afterwards perfectly. They provided a major improvement for an affordable price. I would highly recommend them to anyone looking for insulation solutions.

​​We called for a consultation, and John came out to our house to look around and give us a full home analysis on potential areas of heat loss in our house. John was extremely personable and really cared for our opinion and was not pushing for the sale, but what was right for our house. Thank you John for the great experience, and thank you RetroFoam for the opportunity and experience.

Mike, James, Mason and Scott were excellent! They were very responsible and completed the job perfectly! They cleaned up after themselves and were respectful of my home. I am looking forward to lower heating bills this winter and I think doing this insulation will pay for itself. I’m sorry we didn’t do it sooner.
