Improve Your Attic or Basement with These Tips

For maximizing home energy savings and comfort in summer, turn your attention to the basement and attic. These areas are common sources of energy loss and any improvements made will help you save money. Here are some tips.

Moisture Control

Basements and attics often suffer from high humidity. Any area of the home that remains damp will increase humidity throughout the rest of the home. This decreases comfort and makes your home feel warmer, which means your air conditioning costs will likely go up.

It also creates an opportunity for mold growth, and the problem won’t be confined only to these spaces. Air quality will suffer throughout the home as mold spores are easily airborne.

Check for roof leaks, damp areas and moldy insulation in your attic. Have the ventilation system checked to ensure there is appropriate airflow. This helps exhaust moisture and prevents heat buildup.

In the basement, fix all leaky plumbing pipes, but also check the walls for cracks, gaps or a damp, clammy feeling. You might need to have your basement moisture-sealed by a professional.

Sealing Air Leaks

Air leaks are a big source of energy loss in summer because they allow hot outdoor air into your home. The basement and attic are common areas for air leaks because of chimneys, entrance points for electricity and plumbing, and other structural breaches. Seal small leaks with caulk and seal larger air leaks with expandable foam or similar appropriate material.

Sealing Ducts

Ductwork is often routed through basements and unconditioned spaces such as attics. Leaky ductwork in either area can cause energy loss, but this is extreme in unconditioned spaces where hot air can enter ducts through gaps. Seal these with metal-backed tape.


Attic insulation keeps the summer heat from radiating down through the ceiling. Have a contractor inspect your insulation to make sure it is in good condition, hasn’t shifted and that there is enough of it. Insufficient insulation is a top source of energy loss.
