    We have already noticed a decrease in our power bills and the house is a lot more comfortable in the back rooms. My mold allergy headaches are gone. We used to have a lot of brown recluse spiders in the house and there hasn't been a single one since Dr. Energy air-sealed our house. This work was completed before the heavy rains in April and kept our crawl space snug and dry while others on the street had to deal with water issues. We are very happy we had this done.

    I didn't understand why I had to fill out a survey with the guy standing there and now this one - the one where the guy is standing there was a little uncomfortable - not that there was anything wrong with the service.

    Customer Review

    By Nancy W.
    St. Louis, MO

    Dr. Energy Saver St. Louis sealed our house from the basement. They filled in the rim joist so that the air from the outside couldn't get in and also filled part of our basement floor over the rocks. They were very good. We have a very old house and we have an area that is just rock because it's holding up years. My experience with them was very good. For one thing they were very responsive when I called. They sent someone out pretty quickly to do an evaluation. They also had me fill out a form listing everything in my house I think might be a problem for energy savings. They focused on what I wanted to do and not what they wanted to do. They were really comprehensive. They went through our whole house and gave us an evaluation of everything in the house with pictures so it was very comprehensive. They were very respectful and very down to earth. The workers did a good job and cleaned up after themselves. They were very pleasant people to work with.

Not many companies can say they know how to make a home more comfortable and energy efficient at the same time, but we sure can! Whether your home needs spray foam insulation installed in the attic or rigid foam boards installed in the crawl space - we're the contractor to call.

With our home energy audit complete we can accurately identify the largest energy weaknesses within your building. If we discover that your building needs home insulation installed, we will provide the benefits of the insulation material that will best suit your buildings needs.

Here are a few of the "symptoms" homeowners experience before calling us for help.

  • Inconsistent temperatures
  • Dirt crawl space
  • High energy bills
  • Cold Floors
  • Drafts
  • Allergy Problems

Whether you schedule a complete home energy audit or just want us to focus on one part of your home, we will provide you with the right solutions to your concerns.

Did you know that a wet crawl space is the perfect environment for mold to grow? Unfortunately, this same air greatly affects the first floor of your home. Our crawl space encapsulation system will completely seal and insulate your crawl space, reducing the potential for moisture damage and improving your home's comfort and health!
