Windows and doors are usually the weak point of energy efficiency in well insulated homes. Approximately 25%1 of a home’s energy is lost through the windows alone. Double-paned windows can reduce this figure down to as low as 7%. Plus, double-paned reduce noise pollution. Adding reflective coating to and solar screens will improve the energy efficiency even further.
Doors generally lose energy around the perimeter. Air gaps or damaged weatherstripping will allow air to freely flow in and out. Weatherstripping is generally cheap and easy to replace. Sometimes the gap is large and it’ll require the weatherstripping to be stacked.
Window Inspection Checklist
You will want to inspect the caulking seal on the exterior side of the house each fall and spring. Water moisture present in between panes of glass is an indication of a leak.
- Walk around the exterior of the house and inspect the caulking seal around the perimeter of each window. Look for gaps and cracks.
- Remove damaged caulking with a putty knife and clear up the remains with a fine grade piece of sandpaper.
- Use an exterior caulking to fill in the crack between the trim to seal it up. Make sure to apply plenty of material or it will crack again. You can use your finger to smooth it over.
Door Maintenance Checklist
The weatherstripping around the perimeter of each door keeps it sealed. It will wear out over time with generally use of the door. Other side effects from use is wear on the hinges and locks seizing up. Keeping hinges and locks well maintained will prevent the door from seizing up or becoming “squeaky.”
- Inspect the weatherstripping around the perimeter of each door. Remove damaged parts and replace with the same type. If a gap is still present or there is a draft, consider stacking weatherstripping to ensure the door is sealed.
- Place a couple drops of penetrating oil at the top of hinges so it runs down along the pin. Clean up any excess with a paper towel.
- Use dry graphite on door locks to keep them from freezing up. Do not use dry graphite on electronic locks as it can insulate the electrical connection.
