Foam USA, LLC is a spray foam insulation company whose Massachusetts home improvement contractor registration (190521) is expired on the state registry. A 2022 customer said Mark and crew worked on a complicated attic situation that took months to fix, came back repeatedly to check on conditions in the attic, and finally installed foam. That 2022 customer reported no more moisture problems and noticeable heat retention that winter. A 2021 reviewer wrote that they insulated the attic of the reviewer's Victorian home, and said closed cell spray foam is not cheap but worth it. A 2020 customer said Shane from Foam USA listened to their concerns and that his application of the spray foam was well done. A 2019 customer wrote that Mark came to look at the job within a week and that the rim joist area of their 1991 colonial was spray foamed with closed cell foam, replacing blanket fiberglass. That 2019 customer called Mark's quote very competitive with others they had spoken with, and said the team took care to prepare the space for overspray. A 2017 reviewer renovating an old house in the Berkshires said Mark Lantz developed an approach for a house that was difficult to insulate because of its age and the way it was built, and that his team left the house clean.
We had a complicated situation in our attic which took months to fix. Mark and crew worked to ameliorate the problem, came back repeatedly to check on conditions in the attic, and finally were able install foam. No more moisture problems and heat retention in the house has been quite noticeable this winter. Great job and very professional.
These guys are very courteous and professional. They did a great job insulating the attic of my Victorian home and the results are VERY noticable. If you're on the fence about closed cell spray foam, don't be! It's not cheap, but it is absolutely worth it.
Insulating our home presented some challenges, and Shane from Foam USA was really diligent about listening to our concerns and needs. He and his assistants did an excellent job. He was not just skilled with the set up of the equipment and materials but his application of the spray foam was very well done. -Kevin
I contacted Mark regarding spray foaming our rim joists area of our 30 x 40’ colonial built in 1991 with closed cell foam (to replace blanket fiberglass), he responded to our request and came to look at the job within a week. We determined that I currently had R8 and not airtight, which was replaced with closed cell foam at R22 which would be airtight. His quote was very competitive to others we had spoken with. The construction of our home was a little different than normal conventional ‘2 by’ lumber, we have TJI joists (wooden I-beams). Along each TJI as it sits on the sill plate is a 2x4 on both sides. As you can see in the picture this creates a challenging area for traditional crack sealing and even fiberglass blanket insulation to do an effective job at insulating the ‘critical seal’ area. The infrared image was taken on March 20th, when it was 25°F outside. The temperature listed (57.7°) is what the crosshairs in the center of image is sensing. The blue and dark areas show significantly colder areas (gap between TJI and 2x4). The solid blue section on the bottom is the top of the concrete wall, the horizontal red line is the hot water heating pipe. I have also included an after shot when it was spray foamed. This winter when the weather gets colder I hope to be able to take another infrared image for comparison. I highly recommend Mark and his team at Foam USA. They were easy to work with, they took care to prepare the space for over spray, and willing to work with me with custom add-ons that I requested. I would not hesitate to refer or use them again.
We have been renovating a very big, very old house in the Berkshires for three years. In all that time, we have dealt with no one more professional, capable, and courteous than Mark Lantz and his team from Cozy Home and Foam USA. The house was difficult to insulate because of its age and the way it was built, but Mark took time and used his impressive knowledge to develop the best approach, down to the smallest detail. His team was clearly experienced. They worked efficiently and thoroughly, and left the house remarkably clean--considering what a mess the spray foam is in general. I would recommend Cozy Home and Foam USA to anyone.
