Keep Warm Air In and Cold Air Out!

Air Sealing

When it comes to air sealing services for your St. Louis area home, the team at Greenmark Home Performance has you covered. This is one of the most important jobs that a weatherization crew can perform. It involves closing up areas of the home where there could be issues with heat gain/loss. This is when hot/cold air from outside gets into the home, or conditioned air from inside escapes. All of these things can cause the heating and cooling systems to work much harder than normal, and this can be the cause of skyrocketing energy bills each month.

In addition to having lower energy bills, with this service you will also have a home that is much more comfortable, durable, and healthier. Caulking and weatherstripping are two of the most common techniques used with sealing. This involves checking window and door frames to be sure that they are properly sealed so that air can't get in or escape. Additionally, cracks in the foundation or in frames can be caulked for a tight seal.

Crawl Space Encapsulation

If you have a crawl space under your home, this is one of the biggest areas of air loss if it isn't sealed properly. To take care of the problem, we can make use of encapsulation work that will involve the installation of vapor barriers, floor liners, sump pumps, dehumidifiers for moisture control in the air, and more.
