Mammoth Home Renovations is a leading example of home comfort, known for outstanding customer experiences, superior work quality, and a thriving work culture.

Founded in 2021 as Fox Cities RetroFoam, Mammoth Home Renovations has been delivering premium foam insulation services to the Fox Valley and northern Wisconsin areas. We specialize in spray foam and injection foam products that rescue homeowners from uncomfortable living conditions and high energy bills to provide total home comfort. Our commitment to excellence in homeowner relations is unwavering.

Our founder, David Coulson, began with his own home, making it more efficient by upgrading its insulation beyond the original construction standards. This personal project not only improved his home’s comfort but also significantly reduced heating and cooling costs.

Starting with just two employees, Mammoth Home Renovations has rapidly expanded to a team of 20 over the past two years. This growth reflects our dedication to providing top-notch foam insulation services to a wider audience in northern Wisconsin.

Our expansion marks a significant milestone in our commitment to delivering high-quality foam insulation and home comfort solutions. With our established location in Little Chute, we aim to cater to the insulation needs of residents throughout the Fox Valley area and beyond. Our team remains steadfast in delivering exceptional quality and a customer-focused approach, which has been the cornerstone of our company since its inception in 2021. Mammoth Home Renovations continues to prioritize energy efficiency, homeowner satisfaction, and comfortable living environments, ensuring that every homeowner experiences the benefits of our premium foam insulation solutions.

At the start of 2024, our acquisition of a division specializing in windows, siding, and doors, bringing over 25 years of industry experience reflects our commitment to offering comprehensive home improvement solutions to our customers. With our expanded capabilities, we are able to provide high-quality windows, durable siding options, and stylish doors to complement our foam insulation services. By combining our insulation expertise with decades of experience in the windows, siding, and doors industry, we are well-positioned to meet the diverse needs of homeowners across northern Wisconsin. Backed by decades of industry expertise and a commitment to excellence, we are excited to continue serving homeowners with unparalleled craftsmanship and exceptional customer service in all aspects of home improvement.
