As a St. Louis homeowner, you know how important it is to invest in your home's energy efficiency when doing remodeling or repair work. This can help you to save a lot of money in the long run on your monthly utility bills. During the design phase of your remodeling project, it's a great time to think about what you can do to help with conserving energy in your home. It is recommended to get an energy audit performed by the team here at Greenmark Home Performance during this stage of the process so that you can get a better idea as to what's going to work best for your family and home's unique needs.

What You Can Do


For starters, if you have a heating or cooling system that is older than a decade, there are much more energy efficient models on the market today which are Energy Star® rated. We can provide you with replacement and installation services for ductless AC or "mini split" systems, as well as central heating and cooling units, maintenance, repairs, and more. We want your family to be comfortable in the home.


If your windows feel drafty, then this is a sign that their seal may be weak, the frames may be damaged, or the glass may need to be replaced. We have a variety of replacement glass styles and vinyl frames available for installation in your home. This includes bay, bow, casement, single or double hung, picture, garden, awning, tilt-in, and special-shape varieties.


Your entryway says a lot about your home and family's personality. You want to make a striking impression on passersby and to anyone visiting your home. Besides aesthetics, you also want to be sure that you have a door installed that isn't letting in hot/cold air, or letting conditioned air out. Fiberglass replacement doors are some of the most energy efficient varieties on the market today, and they are available in many different styles.


A home with minimal insulating materials in the attic, walls, or roofing area is going to have a lot of problems with heat gain/loss. We can provide you with both cellulose and spray foam insulation installation services to help keep your home warm in the winter and cool in the summer.

Basements and Crawl Spaces

The area beneath the home is one space that is often overlooked by most homeowners. However, it's an area that requires a lot of attention. If the basement leaks, or if the crawl space isn't sealed properly, it's going to cause a lot of damage and problems for the rest of your home. We can help.
