For Electric & Natural Gas Customers
A properly insulated basement can help reduce your natural gas and electric energy costs. However, basement walls are one of the most controversial areas of a house to insulate and seal. One step you can take is to properly seal cracks and openings. Proper air sealing in your home can significantly reduce heating and cooling costs, improve building durability and create a healthier indoor environment. A couple of areas to pay attention to are the area where your house sits on the foundation and also where any pipes or wires go through to the outside for your phone, cable, water faucet and dryer vent. These holes are usually drilled larger than needed and let drafts and insects into your home. Sealing these oversize holes will save on your heating and cooling bill.
