Sliding & Closet Door Track Repair
Sliding and closet door track repair is the hardware fix for bifold, bypass, sliding patio, and mirror sliding doors — pivot pins, roller carriages, bottom guides, and track straightening or replacement, with common Stanley, Johnson, and Acme parts carried on the truck — starting at $180 for a bifold pivot or bottom guide swap. The bifold door in the hall closet that jumps off the pivot every time it gets pulled past 45 degrees, the bypass set in the master bedroom that overlaps wrong and bumps in the middle, the sliding patio screen jammed in the bottom track because the rollers cracked years ago. Closet and sliding doors fail almost always at the hardware — pivots, rollers, tracks, and bottom guides — not at the door panel itself. We re-seat most closet doors in 30 to 60 minutes.

What Does a Track Repair Visit Include?
Sliding and closet door track repair covers five door families — bifold pivot pin and bracket re-set, bypass roller swap, sliding patio door bottom-roller replacement, bottom guide replacement, and mirror sliding door heavy-duty roller upgrades — plus track straightening or full track replacement in matched Stanley, Johnson, or Acme profiles. Bifold and bypass closet doors run on overhead tracks with pivot pins or roller carriages; sliding patio doors run on bottom tracks with weight-rated rollers; mirror sliders combine the load problem with a fragile panel. The truck carries the common parts for all five.
How Do You Fix a Bifold Door That Keeps Falling Off?
Bifold doors hang on a top pivot pin (the part that drops out and lets the whole panel fall) and a bottom bracket (the part that holds the panel vertical). When the top pivot pin cracks — they are usually plastic — the door comes off cleanly. When the bottom bracket loosens, the door tips and rubs the trim. We replace pivots with metal upgrades on common Stanley and Acme profiles, tighten or re-set the bottom bracket into solid wood, and re-seat the panel in the track.
Bypass Roller Swap
Bypass closet doors hang from two roller carriages on each panel that run inside a U-channel overhead track. The rollers wear flat over the years, then crack — and the door starts to drop or bind. We replace rollers in the common Stanley, Johnson, and Acme profiles on the truck, level each panel against the floor, and check that both panels meet flush in the closed position with the right overlap.
Sliding Patio Door Roller Replacement
Sliding patio doors carry their weight on bottom rollers that adjust up and down with a Phillips screw at each end of the panel. The rollers crack, the bearings seize, and the panel starts to drag along the track. We pull the panel (one or both, depending on access), swap to tandem heavy-duty rollers rated for the panel weight, clean and lubricate the track, and re-seat. Patio screen doors covered on the screen door repair page.
Track Straightening & Replacement
An aluminum or steel track that has been bent — usually from a door yanked off forcefully or kicked back into place — has to be either straightened in place (small bends) or replaced (sharp kinks that catch the roller). We use pry tools and hardwood blocks to relieve minor bends; for full replacement we match the track length and profile (Stanley 2610, Johnson 100PD, Acme 1090) and re-mount with the same fastener pattern.
What Is a Bypass Door Bottom Guide and Why Does It Go Missing?
The single most-common bypass-door call. The bottom guide is a small plastic or metal pin that screws into the floor between the two panels and keeps them from swinging out at the bottom. It goes missing in every house with kids — chewed by a vacuum, stepped on, or never installed by the contractor. We replace the bottom guide with a stamped-steel or polycarbonate model rated for the panel weight, with the right floor anchor for hardwood, tile, or LVP.
Mirror Sliding Door Repair
Mirror panels weigh 40 to 80 pounds each — far heavier than standard hollow-panel sliding doors — and burn through standard rollers in 18 to 24 months. We replace with heavy-duty tandem rollers (rated 100 lb+ per pair), check the track for bow under load, and reinforce the top header with a sister stud if the track is sagging. Mirror panels handled carefully with masking on the edges before removal.
How Sliding & Closet Door Track Repair Works
Five sequential steps from identifying the door family to the final glide-test — the order we follow on every closet and sliding door call so the right parts come off the truck the first visit.
Identify the Door Family & Track Profile
Bifold, bypass, sliding patio, or mirror — each has a different failure pattern and a different parts kit. We identify the brand (Stanley, Johnson, Acme cover over 90% of U.S. installs from the 1970s onward) and pull matching pivots, rollers, or guides from the truck.
Pull the Panel & Inspect Hardware
Lift the panel off the track (two techs on mirror panels with painter's tape and foam strip masking the edges first), inspect every roller carriage or pivot pin for cracks and flat spots, and check the track for bends or bows from previous forcing.
Replace Worn or Cracked Hardware
Swap rollers on both panels of a bypass set even if only one failed — they wear at the same rate and replacing one means a return visit in three months. Bifold pivots upgrade from plastic to metal as a standard fix. Sliding patio rollers upgrade to tandem heavy-duty rated for the panel weight.
Straighten or Replace the Track
Aluminum or steel tracks with minor bends get relieved in place with pry tools and hardwood blocks. Sharp kinks that catch the roller need full replacement — track length matched to the existing profile (Stanley 2610, Johnson 100PD, Acme 1090) and re-mounted on the same fastener pattern.
Bottom Guide & Re-Seat
Install or replace the bottom guide (a stamped-steel or polycarbonate pin) with the correct floor anchor for hardwood, tile, or LVP. Re-seat the panel in the track, level against the floor, verify both panels meet flush in the closed position, and run a five-cycle glide test before sign-off.
Sliding & Closet Door Track Repair Pricing
Final pricing depends on the door type, the failure mode, and whether the track needs replacement. Most repairs use common parts on the truck and finish in one visit. Request a free estimate for an accurate quote.

Why Handis for Closet Door Track Repair
The single most-common diagnosis we make on closet doors is the door that has been off the track for so long that the previous fixer bent the track trying to force it back. The original failure was almost always a $3 roller or a missing bottom guide. The bent track now needs straightening or replacement on top of the original fix. The lesson — and it is a permanent one — is to stop forcing a sliding or bifold door the moment it stops moving smoothly. The hardware is telling you something specific, and forcing it just adds work to the repair.
Common parts on the truck for the three brands you actually have
Stanley, Johnson, and Acme account for over 90% of bypass and bifold systems installed in U.S. homes from the 1970s onward. The truck carries pivot pins, roller carriages, bottom guides, and short track sections in those three profiles — so most repairs finish in one visit without a parts order.
Metal pivot upgrades, not the plastic ones that just cracked
The original pivot pins on most bifold doors are plastic and brittle. The door fell off because they finally cracked. We replace with metal upgrade pins on every bifold repair — the same fix the manufacturer offers as a parts kit. The new pivots do not crack from the same fatigue.
Both panels checked, not just the broken one
On a two-panel bypass or a four-panel bifold, the other side is usually two months behind the side that failed. We pull every panel, inspect every roller, and tell you which ones are close behind so you do not call us back in three months for the same job on the next panel.
Mirror panels masked before they move
Mirror sliding doors crack the moment a hand or a tool catches the edge. We mask the edges with painter's tape and a foam strip before any panel comes off the track. Out of several hundred mirror repairs, we have never broken one.
30-day workmanship guarantee
If a closet or sliding door we repaired falls off the track, binds, or stops closing within 30 days because of our workmanship, we come back and fix it at no extra charge. The guarantee covers our installation and the parts we supplied. It does not cover damage from forcing a door past resistance or impacts from outside our work.

Customer Reviews
Sliding and closet door track repair reviews from real Handis customers.
Master bedroom bypass set, both panels dragging and the bottom guide had been missing for years. Tech replaced four rollers (Stanley profile), installed a new steel bottom guide anchored into the LVP, and the doors glide silently. He showed me the cracked rollers — every one of them flat on the bottom. Forty-five minutes.
Bifold door in the hall closet had been off the track since spring. I had tried to put it back twice and bent the track trying. Tech straightened the track with pry blocks, replaced both pivots with metal ones, and re-seated the panel. Closet door working for the first time in six months. He also showed me how to put it back if it ever comes off again.
Sliding patio door so heavy I had to use two hands to slide it. Tech pulled the panel, showed me both bottom rollers cracked through, and swapped to tandem heavy-duty rollers. Cleaned and lubricated the track. The door slides with one finger now. He also said the track was on the verge of needing replacement but we got another two years out of it with cleaning.
Mirror closet doors that had been jumping off the rail for a year. Tech masked the edges before he moved them, swapped all four rollers to heavy-duty tandems, checked the track for bow, and sistered a piece of framing to the header where the track was sagging under the weight. Mirror doors glide and stay put. He never came close to breaking a panel.
Bottom guide on the kids' closet bypass had been missing since we moved in. The doors swung out at the bottom every time. Three-minute fix, $180 well spent. Should have called two years ago.
