Bethesda MD homes have to handle wide seasonal swings, so small door defects show up fast. A gap that is barely noticeable in spring can become a cold draft in January or a source of sticky humidity in August.

Materials matter too. Thin hollow-core exterior doors, tired wood doors that have absorbed moisture, and aging sliding patio doors often perform poorly compared with newer insulated assemblies. Even when the door itself is still serviceable, the frame and sill can be the real source of the problem.
