The number one reason sliding doors stop sliding. We replace worn, corroded rollers with heavy-duty stainless hardware and get your door gliding with one finger — usually in a single visit.
Most repairs start at $275, including parts, labor and a 1–3 year warranty.
Every sliding glass door rides on a pair of rollers not much bigger than a coin. In Florida's coastal climate, those rollers live in the worst environment in your house: a track that collects salt air, sand, pet hair, and rainwater. Over time the bearings corrode and flatten — and the full weight of the glass starts dragging on metal.
That's when you feel it: sticking and jerky movement that makes the door a two-hand job, misalignment that opens gaps around the frame and hurts your energy bill, and a latch that no longer lines up — which means the door doesn't truly lock. Left alone, a failed roller gouges the track itself, turning an affordable repair into a bigger one.
Our technicians replace worn rollers with precision — restoring smooth function and the security of a properly seated, properly locking door.
We check the door's overall condition — rollers, track, frame, and lock alignment — so nothing gets missed.
We identify the exact wear pattern and match the optimal replacement rollers for your door's brand and weight.
The panel comes out, high-quality stainless rollers go in, and the track gets cleaned and dressed while we're there.
We re-hang, align, and adjust the door, then have you slide it yourself — effortless, quiet, and locking true.
The classic signs are a door that needs two hands or a shoulder to move, grinding or scraping noises, a door that bounces or jumps as it travels, and visible aluminum shavings in the track. If the door has dropped and now scrapes the track, the roller wheels have usually collapsed entirely.
Lubricant helps a healthy door, but it can't fix a collapsed bearing. Spraying a worn roller usually buys a week or two of easier sliding while the wheel keeps chewing into the track — which turns a simple roller job into a track repair as well. If the door is already heavy, it's parts, not lube.
Most single doors are done in about an hour on site. We lift the panel out, replace the rollers, clean and inspect the track, re-hang the door, and adjust it so it glides and locks correctly. Multi-panel and heavy hurricane-glass doors take a little longer.
Yes. Treasure Coast homes have decades of different door brands, and we stock the common roller patterns on the truck — including heavy-duty stainless steel replacements that outlast the originals in our salt-air climate.
A tandem assembly carries two wheels in one housing, so each wheel takes roughly half the corner load and the panel rides level across a slightly worn rail. A single roller puts the whole corner load on one bearing. Heavier and newer panels almost always run tandems, while older and lighter residential doors often run singles. You can tell by looking through the adjustment plug in the bottom of the stile: a tandem is a long body with a wheel at each end and the height screw between them, a single is a short body with one wheel centered underneath.
No, and anyone who says otherwise is doing something else. The roller assemblies sit inside the bottom of the panel and bear on the rail, so the panel has to come up and out of the opening to get at them. That is also the only chance you get to clean and inspect the parts of the track the panel normally covers. Taking the panel out and rehanging it correctly is most of the skill in the job, particularly on heavy impact glass, which is exactly why we bring a second set of hands to large panels.
Almost never. A groove means a seized wheel has been skidding along the rail instead of rolling, and it tells us the roller failure went on a long time. Light scoring can usually be dressed during the service so the new wheels have a clean crown to run on. Deeper damage needs the rail addressed properly, which is more than a roller job but still a fraction of replacing the opening. What matters is that you hear which one you have before the quote, not after the panel is out.
Not on their own. Nylon will not corrode, which sounds like the answer near salt water, but nylon flat-spots under sustained load and gets brittle after years of heat and UV. More to the point, a nylon tire usually still runs on a steel bearing, and it is the bearing that salt kills. What actually survives coastal air is a sealed bearing in a stainless assembly: the seal keeps the salt film out of the race, and the stainless resists what gets past. That is the specification we fit on doors close to the water.
Your declaration decides it, not the manager's memory. Most Florida declarations treat a slider serving one unit as a limited common element, then split responsibility so the operating hardware sits with the unit owner while the frame and exterior sit with the association. Appearance rules usually govern anything visible from outside. Read the maintenance and repair article of your documents before you call anyone, and get the answer in writing. If your manager needs the scope described before signing off, say so when you book and we will set it out plainly.
Repairs start at $275, and that figure includes parts, labor and a one to three year warranty on both. Where a particular door lands above that depends on how many panels actually move, how heavy the glass is, whether the roller pattern is a common one we carry on the truck, whether the rail needs work as well as the rollers, and how accessible the opening is. We give you the diagnosis and the number before any work starts, so nothing about the price arrives as a surprise once the panel is out.
Yes, and it is a sensible way to do it. Doors that stand unused through a Florida summer corrode fastest, because nothing wipes the salt film off the bearings for five humid months. We work with property managers and keyholders regularly, so the owner does not need to be in the state for the visit. If someone checks your property, ask them to slide every door fully open and closed once a month as well. Two minutes per door prevents most of the arrival-night calls we take in October and November.
Often, yes. Worn rollers let the panel sag, and a sagging panel carries its latch below the keeper it is supposed to catch, which is why the lock first needs a jiggle, then a lift and hold, then stops catching at all. Restore the ride height with sound rollers and set the adjustment screws, and the original latch usually clicks home the way it did when it was new. Where the latch genuinely is worn too, we replace it with the panel already sitting correctly underneath it, so the new hardware is not inheriting an alignment problem.
There is no universal sliding door roller. Two doors that look identical from across the room can take housings that share nothing, and ordering the wrong pair is the most common reason a weekend repair stalls with the panel leaning against a wall. Five minutes with a phone camera settles it.
If you would rather not guess, send us the photos and tell us the town. Between build era and wheel size we can usually name the assembly before we arrive, which is a large part of why most jobs finish in one visit.
A tandem assembly spreads the panel's weight across two wheels in one housing, so each wheel carries roughly half the load and the panel stays level as it crosses a slightly worn spot in the rail. A single roller puts the whole corner load on one bearing. Heavier panels almost always run tandems; lighter and older residential doors often do not.
You read it through the access hole in the bottom of the stile, or by tipping the panel out. Look at the shape of the body sitting on the rail: a tandem is a long body with two wheels visible at its ends and the height screw between them. A single is a short body with the wheel centered under it.
One trap catches homeowners and handymen alike. People pull one roller, order a matching pair, and only then discover the second panel takes a different housing, or that a previous repair fitted a single into a rail that was cut for a tandem. That mismatch is why one panel glides and the other still drags after a DIY job. Both ends of both panels get checked before we order anything.
Every page in this trade tells you salt air is hard on doors. Almost none of them says what salt air actually does, so here is the mechanism.
Airborne salt aerosol settles into the track and works its way into the roller housing. Salt is hygroscopic, meaning it pulls water vapor out of the air and holds it as a permanent film against metal. That film is an electrolyte, and it puts two dissimilar metals in electrical contact: the plated steel of the wheel and axle, and the aluminum of the housing and rail. Aluminum is the less noble of the two, so it gives up material preferentially. That is why coastal tracks pit and bloom white powder around the roller path while the wheel itself still looks serviceable. Once the plating on the steel is breached, the bearing race rusts from the inside, where no spray can reach it.
The full chemistry, including why summer is worse than winter, is in our salt air explainer.
A single-pane 1980s slider panel and a modern laminated impact panel of the same size are not remotely the same object. The impact panel carries two plies of glass bonded around an interlayer in a heavier frame, and the difference in mass is measured in tens of pounds per panel, not a few.
That mass lands on the same two contact points. Bearing load is what drives fatigue, so a roller sized for a light panel and asked to carry a heavy one does not fail differently, it fails sooner: the race wears, the wheel develops flat spots, and the panel drops out of level while the door is still relatively young.
This matters here more than in most of the country. Much of eastern St. Lucie and Martin County sits inside the Wind-Borne Debris Region under the Florida Building Code, so rated opening protection is common and impact glass is everywhere in post-2005 construction. Production builders regularly specified the same roller across a range of panel weights because it was one part number instead of three.
When we fit rollers to a heavy or impact panel, they are rated for the weight actually hanging in the opening. It is also why we bring a second pair of hands to a large panel rather than levering it out alone.
New rollers running in a machined-out rail will feel better for a season and then repeat the failure. Anyone quoting a roller job without looking at the track is guessing, so here is what we check and what each answer means.
A clean rail plus dead rollers is a straightforward hardware job. A grooved rail needs the rail addressed as well, and we say so before quoting rather than after. A settled opening is a third problem again, and no roller will fix it. The seven-stage version of this, with the sound each stage makes, is in our guide to the signs rollers are going.
Build era tells us more before we arrive than the brand on the handle does. Three cohorts cover most of what we open on the Treasure Coast.
1970s and 1980s aluminum. The older grids in Fort Pierce, eastern Port St. Lucie, and around Stuart are full of thin-frame aluminum sliders with light single glazing. The frames were overbuilt, the glass is usually still fine, and the original plated-steel rollers are decades past their service life. These are the best repair candidates on our route: stainless hardware and a track service typically buys another decade for a fraction of what a new opening costs.
1998 to 2006 boom build. Whole phases went up on the same hardware specification, so the rollers reach end of life on the same schedule across a street. If three neighbors are complaining about sticking doors in the same season, that is not coincidence, it is a hardware cohort aging out together.
Post-2005 impact. Better glass, heavier panels, and hardware chosen to a price underneath it. These doors often need rollers earlier than their owners expect, because the weight was never matched by the assembly carrying it.
Which cohort your street belongs to is worth knowing. Our city pages go through the build history town by town.
We are not going to pretend this is never a homeowner job. On a light, standard single-pane panel with an intact rail, an accessible stile plug, and a second person to steady the glass, it is a real afternoon project: lift the panel clear, swap the assemblies, rehang, set the height screws, test the latch.
Three situations turn it into a bad idea, and they are not about skill.
Our fuller take on what is safe to try, and which shortcuts quietly cost more, is in DIY versus a pro.
Nobody can quote a slider honestly off a phone call alone, but you can know exactly what moves the number, which is more useful than a headline figure that changes when the technician arrives.
Repairs start at $275, and that figure covers parts, labor and a one to three year warranty on both. We put the diagnosis and the number in front of you before any work starts. The wider breakdown of what a complete quote should contain is in our Florida cost guide.
This question stops more balcony door repairs than any hardware problem, and most owners are told the wrong answer by a neighbor rather than by their documents.
The declaration decides it, not the association's habit and not the manager's memory. Most Florida declarations treat a slider that serves one unit as a limited common element and then split responsibility inside the maintenance and repair article: the operating hardware and interior of the panel usually fall to the unit owner, while the frame, the exterior face, and anything structural usually fall to the association. Appearance rules often sit on top of that and govern anything visible from outside, which is why finish and glass questions get referred to the board while a roller swap generally does not.
Two practical points. Read the maintenance and repair article yourself before you call anyone, and get the answer in writing rather than over the counter in the lobby. If your manager wants the scope of work described before they sign off, tell us when you book and we will describe what the door needs plainly enough to forward.
The full walk-through, with the language to look for in your documents, is in who is responsible for a condo sliding door.
Every autumn we take the same call. The door was fine when they locked up in spring, nobody touched it, and now it will not move. Owners assume something was wrong before they left. Usually the opposite is true: nothing being touched is precisely the problem.
Motion is what saves a coastal roller. Every pass of the panel wipes the salt film off the bearing surfaces and redistributes what lubricant is left. A door standing still for five humid months lets that hygroscopic film sit undisturbed against the race through the hottest, wettest part of the year, which is exactly the condition corrosion wants. Add a closed house with the thermostat set high, sand that blew into the track in a summer storm and then packed down, and a latch left engaged so the panel bears against its keeper the whole time.
Two things blunt it. Have whoever checks the property cycle every slider fully open and closed once a month, which takes two minutes per door and is the single most valuable thing a keyholder can do. And book the doors into a close-up and open-up service rather than discovering the problem on arrival night. We work with property managers and keyholders regularly, so the owner does not need to be in the state. Seasonal rentals have a checklist of their own in our rental property guide.
The economics are not complicated. In a sliding door, the glass and the frame are the expensive parts and they last for decades. The rollers are the consumable, and they are the part that fails. Replacing an entire opening because a pair of bearings corroded is like replacing a car because the tires wore out. That is the whole of our position, and it is why we have built the business on repair.
But repair is not always the right answer, and a company that never says so is selling you something too. Replacement genuinely wins in these cases:
If your door is one of those, we will tell you on the visit and you can go and get replacement quotes with a clear head. Most doors are not. Across five years and more than 1,600 doors on the Treasure Coast, the overwhelming majority needed hardware, not a new opening. See what else we handle on the services page, or describe the symptom and we will tell you which category you are in.
