1. Seal Exterior Doors — About 10 Dollars
A door sweep or draft excluder at the bottom of every exterior door seals the gap for 8 to 15 dollars. Self-adhesive foam weatherstripping at sides and top adds another layer for 5 to 10 dollars. Check all exterior doors including the garage-to-house entry — frequently the largest single door infiltration point in Isabella County homes.
2. Caulk Window Frames — About 15 to 20 Dollars
A tube of paintable latex caulk at 4 dollars applied to the interior perimeter of every exterior window addresses frame air infiltration for a full Isabella County heating season. This reduces heat loss at the frame independent of the window glass itself.
3. Window Insulation Film — About 20 to 30 Dollars
For single-pane windows not yet being replaced, window insulation film creates a dead-air space functioning similarly to a second pane. A temporary seasonal measure — EP VueSeries replacement windows from Energy Plus provide genuine Zone 5 thermal performance that no film kit matches.
4. Insulate Your Water Heater Tank — About 25 Dollars
Tank-style water heaters in Isabella County homes lose standby heat continuously. An insulation blanket at 20 to 30 dollars reduces this loss. For gas heaters: keep thermostat, air intake, and burner access unobstructed. Payback: one to three years.
