WHAT WE OFFER

Residential Wall Insulation Services in St. Louis, Missouri

At Gateway RetroFoam, we specialize in two types of insulation: foam injection wall insulation and spray foam insulation. Both options are designed to enhance the comfort and energy efficiency of your home, keeping you warm in the winter and cool in the summer.

Foam Injection Wall Insulation

Foam injection wall insulation is perfect for existing homes, installed without removing drywall, completed in just one day from outside your home. It creates a highly efficient thermal barrier, maintaining consistent indoor temperatures and reducing HVAC strain. Enjoy lower energy costs, reduced noise, and peace of mind with our Class 1 Fire-Rated insulation.

Spray Foam Insulation

Spray foam insulation is a great option for new home construction and metal buildings like pole barns and garages. A 2-inch thick layer of closed cell spray foam reduces utility expenses by 50% and maintains consistent indoor temperatures year-round. Experience energy savings, improved comfort, and a Class 1 Fire-Rated barrier for enhanced safety.

Reduced Energy Bills

Our wall insulation services help you significantly decrease your overall energy consumption, leading to potential savings of more than 30% on your utility bills.

Comfortable Living Space

By improving the air quality in your home, our insulation reduces allergens and pollutants, creating a healthier environment for you and your family.

Better Noise Control

Our insulation services enhance your overall quality of life by dampening outside noise, ensuring a quieter, more peaceful indoor living space.

What Our Customers Are Saying

"Shawn with Gateway RetroFoam was great work with. He was prompt for the estimate appointment and the install. His crew did a great job and left the site clean and tidy. He explained everything thoroughly and the house feels snug and quiet now."
Ria S.
"Shawn was awesome to work with from initial request for information, to the quote and then the installation. He explained everything along the way. Installation was quick and painless, the crew all seemed to really know what they were doing. Already feel the difference in areas of the house that were previously drafty. Can’t wait to see the utility bill savings! Would highly recommend Retrofoam as a product and Gateway Retrofoam for anyone looking for better insulation of their home."
Andrew F.
"Shawn, the owner, and his crew were amazing. They were professional and respectful of our property, cleaning up as they worked and even helping to move some of our belongings. Despite our 30-year-old siding, you can’t tell where they removed and replaced it. Shawn explained everything in detail before and during the process, showing us how they checked the walls before filling them. Gateway Retrofoam is a low-pressure, very affordable company to do business with. We definitely made the right decision choosing them over USA Insulation."
Jeri B.
"Shawn and his crew at Gateway RetroFoam were awesome from start to finish. They arrived at 8:30 am and finished by 5 pm. Throughout the day, Shawn kept us informed about their progress and was very informative. At the end of the day, the crew cleaned up everything, and Shawn made sure we were satisfied. I would give Shawn and his crew five stars and highly recommend Gateway RetroFoam!"
Tom C.
"Shawn and his team were incredibly professional and made the whole process easy. Shawn was a no pressure salesman and gave us respect and comfort. We have already noticed a difference in two days. Thanks Shawn and team! I highly recommend considering this company for your future projects."
Angie A.
"Gateway RetroFoam LLC worked tirelessly, 8:30 AM to 3:00 PM, insulating our villa’s exterior walls. We will definitely keep an eye on the energy usage during the next year to measure improvement. Maggie looks forward to a warmer kitchen in winter, cooler in summer. They did a great job cleaning up during and after blowing in the insulation. Everyone working was pleasant, approachable, and knowledgable, answering any questions we had. Great job guys!"
