Do I have a leaky house?

SPRINGFIELD, Mass. (WWLP) - Small problems around the house can add up to big bucks on your utility bills. They can also make your living space quite uncomfortable.

Heat related costs may amount to more than 50% of your home expenses this winter according to the Department of Energy , DOE.

Signs of trouble include: temperature variation between rooms, condensation on window panes, and frequent drafts.

The culprits may be cracks in windows, doors, or their frames. Limited insulation behind recessed lighting and electrical outlets often prompt air flow.

Reapplying caulk is the first and easiest fix to improve the performance of your windows and doors. The silicone solution is available at home improvement stores for a few dollars a tube. Reseal seams where  window and door frames meet walls and molding.

Remove air conditioning units from windows if possible. A closed window is the best barrier to cold air. Insulated air condition covers are available for units that remain intact throughout the winter.

Lined drapes and shades add insulation to windows. The DOE recommends leaving blinds open during the day on south-facing windows so sunlight warms your house. Be sure to pull the blinds tightly closed when it becomes dark.

Storm windows can cut heat loss up to 50%, according to the DOE .

“Window Kits” are sold at home improvement stores so homeowners can easily and inexpensively add insulation to panes. The plastic liner clings to glass. Some window kits require the use of a blow dryer to attach the sheet. Others are thick plastic that can be taped to window frames. When using the latter, be sure to tape along all edges to create a seal.

Check for weather stripping under exterior doors. It can be replaced for a few dollars. Drafty doors can also be treated with “draft guards”, pillow-like products that block cold air from creeping along the ground.

The area behind electrical outlets is a prime spot for cold air entry into the home. Outlet covers are available that will help insulate these problematic spots. Similarly, recessed ceiling lights in finished attic spaces can cool you down.
