Mark InmanOwner Mark Inman has been in the home remodeling business for twenty-seven years and is from a family of heating and cooling specialists who have operated for nearly 40 years. He is from a large family who lived in a sizeable home, which was leaky and improperly aerated. Mark believes that this environment contributed to a number of respiratory ailments he had when growing up. Because he had this experience in his youth, he fully investigates the cause of these problems and creates an achievable solution. This is his passion so that other families and children do not have to suffer from a poorly insulated, aerated, and humid home.
      Mark Inman, today, lives in a better performing comfortable home with less respiratory issues. Mark Inman has been “green” prior to his professional career. Mark and his family have always been conscious of the impact of containers, packaging, waste and carbon emissions on the environment. In fact, he wrote a thesis on Solar Energy in 1980. Mark Inman is an expert in home energy assessments, insulation, and air sealing. Mark has experience in design and construction practices using building science, environmental sustainability, and universal design. Mark has extensive expertise in home exterior renovation and weatherization.
      Mark Inman is BPI Certified through the Building Performance Institute Envelope and Analyst certification #5036241. Mark Inman believes that home performance is a truthful and honorable way of serving homeowners because it greatly benefits the quality of living. Mark had been motivated to begin this venture because the traditional remodeling industry was only patching over problems and not solving them. Because Home Energy Performance has evolved into a real business model, Mark Inman wants to lead this drive to more comfortable, efficient, and better quality homes.

      We carry general liability insurance coverage of up to $1 million, as well as complete workers’ compensation insurance. This is to help St. Louis homeowners feel confident that should an accident happen on their property, they are not going to be liable for the damages. If you choose to hire an energy auditor or contractor without these credentials, then you may be held liable and your homeowner’s insurance may have to take care of medical bills, damages, and so on.

      WE VALUE QUALITY

      Our company is dedicated to providing the highest quality installation every time. We will go out of our way to ensure your whole house fan is installed to the highest standard.

      The difference in our house is amazing. There used to be an odor we couldn't figure out. Our house had an at least 8-degree difference between the first and second-floor temperature. They are now equal in temperature. The furnace and air conditioner have been working less. The new whole house attic fan is a wonderful addition, as it is very quiet and strong. We've used it a lot. All of our bathroom exhaust fans and the whole house fan is hooked up properly. Everyone that came to our house was very nice and did an awesome job. We are very happy with a good job done. Thank you.

      We were unaware of what was involved in an energy audit, and your auditor took the time to explain everything. We were impressed with the report, which told us the areas in which we need to take action. He never pressured us to use any particular contractors, he just suggested that we go to the Home Energy Team website to select contractors of our own choice. He did an excellent job, and we HIGHLY recommend the Home Energy Team Affiliates. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB! Cynthia Simpson

      - Cynthia Simpson, Saint Louis, MO 63122 Customer

      We had the representative come out for an Energy Assessment. We found that he was very informative, professional, and not high-pressure. He explained in great detail about the program and helped us with any questions or concerns that we may have had. His experience and understanding made us feel comfortable with the program and the company. He made it very personable with us and helped us a great deal. We are very happy with the final results and when we are looking to do some other types of work, Greenmark Home Performance will be first on the list. Cynthia Simpson
