About Us

Your Comfort Is Our Business!


Comfort Seal Insulation is located in Kerrville, Texas. Proudly serving the surrounding Hill Country and the Austin and San Antonio areas. We also travel to most regions upon request.

C.S.I.'s mission is to focus on installing spray foam insulation products that not only encourage sustainable building, but also replace petroleum-based polyols with bio-renewable polyols and chemical blown agents with [safe] water. We help build structures that are safe, healthy, comfortable, energy efficient, environmentally responsible, economical and durable. Our company is committed to a product that is dependable and steadfast for future generations and we provide greener buildings with better performance and less environmental impact. 

We are a nationally certified company for installation of the Energy-Efficient Bio-Renewable Foam Insulation. Our company differs from other spray foam installation companies by using Bio-Renewable Insulation. These types of insulation products are made by integrating natural soy and renewable ingredients, which reduces the amount of petroleum in our products! This allows us to create more environmentally-friendly products that support farmers and reduce our dependence on foreign oil.
