Sliding closet doors are either top-hung, with hangers rolling in a track at the head and a guide at the floor, or bottom-rolling, with rollers in a floor track and a guide at the top. Worn rollers, a broken guide or a bent track makes them jump off, scrape or hang crooked. We replace the rollers, guides and track and rehang the doors, mirror doors included.
What you get
- Rollers or hangers replaced on bypass and mirror doors, top-hung or bottom-rolling
- Floor guides and top guides replaced so the doors stop swinging and scraping
- Bent or worn track straightened or replaced
- Doors rehung level so they meet in the middle and clear the carpet
- Priced per opening, not per door
Top-hung or bottom-rolling: which closet door you have
Bypass closet doors, the two or three panels that slide past each other, come in two systems.
Top-hung doors hang from hangers with wheels that run inside a track screwed to the head of the opening. A small guide on the floor keeps the bottoms from swinging. Most hollow-core wood doors and many steel-framed doors are top-hung.
Bottom-rolling doors sit on rollers that run in a track on the floor, with a guide channel at the top that keeps them upright. Many heavy mirror doors are built this way, since the weight is carried from below.
Look at the top edge of the door. If you see wheels in a channel above it, it is top-hung. If the wheels are at the bottom in a floor track, it is bottom-rolling. Both get the same repair logic, with different parts.
Why closet doors jump off, scrape and hang crooked
- Worn rollers. Nylon wheels flatten or crack, the door sits low on that side and the bottom scrapes the carpet or the track. Eventually the wheel climbs out of the track and the door falls in.
- Broken or missing floor guide. Without it, the doors swing, clash in the middle and jump the track. A guide is a cheap part and the most common thing we replace.
- Bent track. A door that fell in bends the track lip, and then the wheel pops out at that spot every time.
- Hangers out of adjustment. Top-hung hangers have a height adjustment. When one side drops, the door hangs crooked and will not meet its partner.
Mirror doors add weight to all of this, so a worn roller under a mirror door is worth fixing sooner rather than later.

Call or text with your address, how many doors and what the door is doing. You get a firm price before we come out.
What we do
- Lift the doors out of the opening and check each roller, hanger and guide.
- Replace the rollers or hangers with the matching type. We carry the common bypass rollers and mirror door rollers in the usual sizes and mounting styles.
- Straighten a bent track or replace it. Floor tracks and head tracks come in standard lengths that we cut to the opening.
- Fit a new floor guide or top guide.
- Rehang the doors, set the height so they meet in the middle and clear the floor, and test both directions.
Most openings are done in one short visit. Mirror doors need two people on the heavy panels and take a little longer.
Repair or new doors?
Repair is the answer when the doors themselves are sound: flat, not delaminating, mirror intact. New hardware makes an old bypass door run like new, and it costs a fraction of new doors.
Think about new doors when:
- a hollow-core door is swollen, split or coming apart at the bottom, so the roller screws will not hold,
- a mirror is cracked or the backing has separated from the frame,
- the track is an obsolete profile that no current roller fits, which comes up on some older steel-framed doors,
- you want to change the style anyway.
We do the hardware, and we say so when new doors are the better value rather than selling you rollers for a door that is finished. The same thinking is in our repair or replace guide for patio doors.
Mirror doors in particular
Mirror wardrobe doors are everywhere in San Diego condos and 1980s to 2000s tract homes, in Mira Mesa, Rancho Bernardo and the La Mesa condo stock. They are heavy, and the rollers that came with them were often builder-grade.
The usual fault is a flattened or cracked bottom roller on a bottom-rolling door, which lets the panel drop and scrape the track, and a top guide that has worn so the door rattles and leans. We replace both, and if the floor track is chewed, the track too.
If a mirror is cracked, the glass can sometimes be replaced in the frame, but it is often more than the door is worth. We tell you before you spend anything.
Closet door repair across San Diego County
Closet doors are priced per opening on our pricing page, parts and labor for a standard two-door bypass or mirror opening. Three-door and oversized openings are quoted from a photo.
We often do closet doors on the same visit as a patio door roller job, since the house is already on the schedule. Landlords and property managers have us do every closet in a unit at turnover, together with the balcony slider; see our page for landlords.
Send a photo of the top and bottom of the door and we will tell you which system you have and what it needs.
Sliding Closet and Mirror Door Repair: common questions
Why does my closet door keep falling off the track?
A worn roller lets the door sit low until the wheel climbs out of the track, or a broken floor guide lets the bottom swing until the top jumps. A track bent by an earlier fall makes it happen at the same spot every time. New rollers, a new guide and a straightened track fix it.
Can mirror closet doors be repaired?
Yes. The mirror door itself rarely fails; it is the bottom rollers, the top guide and the track that wear. We replace those with parts matched to the door and rehang the panels level. If the mirror is cracked, replacing it in the frame is sometimes possible, but new doors are often the better value.
Do you fix top-hung bypass doors as well as bottom-rolling ones?
Yes. Top-hung doors get new hangers and a new floor guide, with the height reset so the doors meet in the middle. Bottom-rolling doors get new rollers and a top guide, and the floor track is straightened or replaced. Send a photo of the top edge of the door and we will know which you have.
How much does closet door repair cost?
It is a flat per-opening price on our pricing page, covering rollers or hangers, guides, track and labor for a standard two-door bypass or mirror opening. Three-door and oversized openings are quoted from a photo. If we are already at the house for a patio door, closet doors go on the same invoice.
Can a scraping closet door be adjusted without new parts?
Sometimes. Top-hung hangers have a height adjustment, and raising a low side lifts the door off the carpet. Bottom rollers on many mirror doors adjust too. If the wheel is flat, cracked or seized, adjustment only buys a few weeks, and we recommend new rollers while we are there.
