Sliding door roller replacement
The repair we do most. Worn rollers are why a door drags, sticks, or takes two hands. We fit sealed stainless assemblies that shrug off Florida humidity and grit.
$175 per door, all-in. Includes 2 new rollers, basic track cleaning and tax, per door. Track work, if needed, is quoted before we start.
Roller replacement is the single most common sliding glass door repair in Central Florida, and in most cases it's a same-visit fix taking 45 to 90 minutes. If your door drags, grinds, or takes both hands to move, worn rollers are the first thing to check.
What this repair actually is
Every sliding panel rides on a pair of roller assemblies mounted in the bottom rail of the door. Each assembly holds a wheel, a bearing, and an adjustment screw that sets the height of the panel. When the bearing seizes or the wheel flat-spots, the panel stops rolling and starts sliding — dragging metal across metal instead of turning on a wheel. That's when the door gets heavy and the grinding noise starts.
Why it fails faster in Central Florida
Roller bearings are steel, and around Orlando the enemy is grit and humidity rather than salt. Sand, pollen and lawn debris blow into the bottom rail every day; moisture turns them into an abrasive paste that flat-spots the wheel from the outside and works into the bearing through the weep holes. Add the daily expansion and contraction of an aluminum frame between a cool morning and a hot afternoon, and a cheap unsealed roller is a repeat visit waiting to happen. This is why we fit sealed stainless assemblies rather than the cheapest available part.
Signs you need it
- The door takes two hands, or a shoulder, to move
- You hear grinding or scraping along the bottom as it travels
- The panel is visibly lower on one side than the other
- The door jumps or catches at the same spot every time
- The lock no longer lines up with the keeper
- You can see the wheel is flat, cracked, or rusted through the bottom rail
How we do the work
- Lower the panel fully and check the track for damage before touching the rollers — new rollers on a bad track fail within months
- Lift the panel out of the frame and set it on padding
- Remove the old assemblies and identify the manufacturer and profile
- Fit sealed stainless replacements matched to the door
- Rehang the panel and set the height adjustment so the door meets the jamb square
- Clean and lubricate the track with a dry silicone lubricant, not an oil that attracts grit
- Test the lock engagement and the full travel of the door before we leave

Questions about roller replacement
How long do new rollers last?
A good sealed assembly runs many years. The single biggest factor is whether the track underneath is in good shape — new rollers on a worn track wear out fast.
Can I just replace one roller?
We replace them in pairs. Mixing a new wheel with a worn one puts the panel out of level and wears the new one faster, so the savings don't last.
Do I need a new door instead?
Almost never for a roller problem. Rollers are a wear part, like brake pads. If the glass and frame are sound, replacing the whole door to fix a roller costs several times more for no added life.
Other repairs we handle
Track repair & replacement
A worn track destroys new rollers within months. We clean and straighten where we can, and replace the bottom track when it's past saving.
Locks & handles
Broken latches, handles that spin, doors that won't lock. Most are a same-visit fix with hardware we carry on the truck.
Pocket doors
Doors that disappear into the wall are the ones most contractors won't touch. We service hangers and track without cutting your drywall in most cases.
