Sliding door hard to open or sticking — Amsterdam, Noord-Holland

A sliding patio door that drags, sticks, or requires real force to open is one of the most common — and most ignored — home maintenance issues. The usual culprits: debris (dirt, pet hair, small stones) clogging the bottom track, worn-out rollers that no longer glide smoothly, a track that's bent or damaged, or the door panel itself has sagged out of alignment over time. In humid climates, a wood-framed sliding door can swell and bind. A handyman can clean and lubricate the track, replace worn rollers ($100–$300 for parts and labor), realign the door panel, or replace a bent track ($150–$400). If the door frame is warped or the glass seal has failed (foggy between panes), a full door replacement ($800–$3,000 installed) may make more sense. Ignoring the problem risks damaging the track permanently, breaking the lock mechanism, and creating a security gap where the door doesn't seat fully against the frame.
