A sliding glass door that drags or sticks is almost always its rollers, not the whole door — Florida's sand, salt, and lanai grit wear the rollers and pack the track until it fights you.
Plan it — not an emergency.
Common causes:
• Worn or broken rollers under the door — the number-one cause of a hard-sliding door
• A track packed with sand, grit, and debris, common with lanai and pool-deck doors
• A bent or corroded track, especially near salt air on the coast
• Rollers out of adjustment, letting the door sag and bind
• A whole-door or full-frame replacement pushed when a roller-and-track service would fix it
• No attempt to clean and adjust the track before selling new hardware
• No state license number for this building-envelope work
• A quote that ignores whether the door still latches and locks for security
Can sliding door rollers be replaced without a new door?
Yes — rollers are a serviceable part, and replacing them plus cleaning the track restores most sticking doors. A new door is rarely necessary unless the frame itself is bent or corroded.
Why does my slider get harder to open over time?
Grit and salt work into the track and grind down the rollers, especially near a pool or the coast. Regular cleaning slows it, but once the rollers are worn they need replacing to glide again.
Sliding glass door roller & track repair: $150–$650 (typical ~$325)
Rollers and track service; a full door or frame replacement is separate.

Florida licenses this trade at the STATE level (DBPR / CILB (building envelope)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
Basis: FL Stat. 489 (DBPR state licensing).
