How to Tell if Your Doors Are Hurting Your Home’s Energy Efficiency

A door that looks fine from the street can still be quietly costing you money every month. Tiny air leaks, worn seals, and out-of-square frames can undermine comfort long before the door itself looks worn out.

Full replacement becomes harder to avoid when multiple problems show up together. At that point, the cost of piecemeal repairs can start to approach the value of a new unit.
