Sliding Glass Doors & Window Repairs Done Right.

Sticking, grinding, jumping the track: what is your door actually doing?

Almost every call we take opens with one of five descriptions, and each one points somewhere different. Matching the symptom to the mechanism before anyone quotes you is the difference between an hour of roller work and a new door.

• It takes two hands, or a shoulder. The roller wheels have flattened and the panel is dragging on aluminum instead of rolling on steel. The seven roller failure signs put it in order of severity.
• It grinds, scrapes or squeals as it travels. That noise is a bearing that has lost its grease and picked up grit. Caught at the squeal it is usually rollers and a track service. Left a year, the seized wheel cuts a groove and the track becomes part of the job.
• It jumps, bumps or lifts out of the channel. One wheel has collapsed, or the panel has dropped far enough to unseat. Stop using it — a couple of hundred pounds of glass out of its track is a safety problem, not an annoyance.
• The handle turns but the latch misses the keeper. Nearly always a door that has sagged, not a lock that has broken. Run the two-minute lift test before you buy any hardware.
• The screen tears in the same corner every time. The screen frame is out of square, so fresh mesh alone will not hold. Screen fabric repair covers the four checks we run first.

Not sure which is yours? The symptom index runs through twelve of them, or describe it on the phone and we will tell you what it usually means before anyone drives out.

Repair or replace? The honest answer, including when replacement really is right

We are a repair company, so treat this as a biased source and check the reasoning rather than the conclusion. The honest position is that most sliding doors on the Treasure Coast fail at the hardware, not at the door. Rollers, tracks, locks, screens and seals are consumable parts bolted to a frame and a pane that are usually still sound.

A repair is the right call when four things hold: the frame is straight and sound, the glass is intact, the track can be dressed or capped, and rollers for your housing still exist or have a workable equivalent. That describes the large majority of doors we look at.

Replacement genuinely wins in four situations, and we will tell you when you are in one of them.

• The frame has corroded through, or the opening has settled. An aluminum frame that has lost section at the sill, or a racked opening that no longer holds a square rectangle, cannot be trued by hardware. New rollers in a moved frame buy you weeks.
• The sill has lost too much aluminum to cap. A worn rail can usually take a cap track. Once the extrusion itself is chewed away under the wear line, there is nothing left for the cap to sit on.
• The panel is damaged, not just the glass. A fogged or cracked pane is one problem; a bent, twisted or corroded panel behind it is another. We will tell you plainly which one you have — glass clean-up explains the triage.
• You want a different door. A wider opening, a pocket system, an impact rating you do not currently have. That is a renovation decision, and repairing a door you are about to remove is money wasted.

Anything outside those four is a repair. If a company inspects your slider and quotes only a replacement, ask which of the four applies to your door. The cost guide lists the rest of the questions worth asking back.

Barrier island, canal or mainland: what does your address do to your rollers?

Every repair company in Florida tells you salt air is hard on doors. Almost none explains the mechanism, and the mechanism is what tells you how often yours needs attention.

Airborne salt arrives as an aerosol — droplets fine enough to drift on the wind and settle on anything facing the water. The sill of a sliding door is close to a perfect collector: horizontal, sheltered from the rain that would otherwise rinse it, and full of still air. Sodium chloride is hygroscopic, so it pulls water vapor out of humid air and holds a permanent film of brine against metal that never really dries.

Inside a roller housing, that film does two things at once. It carries current between the steel bearing and the aluminum around it, and because aluminum is the less noble metal it corrodes preferentially, swelling into white oxide that pinches the wheel in its pocket. At the same time the brine strips what grease remains from the bearing race. Once the race is dry, wind-blown quartz sand gets in, and quartz is harder than both metals. From that point every pass of the door is a lapping operation on your own hardware.

Distance to open water is the variable that matters most. Ocean-block and barrier island doors take the full aerosol load and age fastest. Canal, riverfront and Intracoastal addresses take a lighter but constant dose — which is why brackish-water homes in Stuart and Port Salerno show corrosion patterns their owners expect to see only at the beach. Inland doors in Tradition or Palm City fail more often from sand and sheer duty cycle than from corrosion.

The full mechanism is here, and our service area page maps the four exposure zones across the route.

What does your build era tell us before we arrive?

Doors fail in cohorts. A neighborhood built across the same three years got the same hardware from the same supplier, and it ages out on roughly the same schedule — which is why we sometimes service four houses on one street in a month. The approximate year your house was built tells us most of what to load on the truck.

• 1970s and early-1980s aluminum. Thin extruded frames, single glazing, and roller housings in profiles that were discontinued decades ago. These doors are usually repairable, but the work starts with identification rather than parts: wheel diameter, housing depth and the position of the adjustment screw all have to be read off the part itself, not guessed from the door. Older Fort Pierce, downtown Stuart and Hobe Sound cottages sit squarely in this group.
• 1998–2006 boom builds. The largest single population of sliders on the Treasure Coast. Standard patio doors on builder-grade nylon or plated-steel rollers with open bearings — perfectly reasonable hardware in a dry climate, a countdown timer in this one. Whole streets in Port St. Lucie and Palm City reach the same failure point together. Parts are plentiful, and the correct move is to fit a grade above the original rather than repeat it.
• Post-2005 impact units. Laminated impact glass weighs roughly twice what the single glazing it replaced did, and plenty of it went into openings on hardware that was only marginally uprated for the load. These doors feel fine for a decade and then fail quickly. They are also the ones where fitting the same-size replacement roller simply schedules the next failure.

Tell us the rough year on the phone and we can usually name the likely failure before anyone sees the door.

Condos, HOAs and associations: whose door is it, and who pays?

A balcony slider in a Florida condo often has two owners at once, and which part belongs to whom is written into your declaration rather than settled by state law. Declarations differ building to building, so the answer for the unit next door is not automatically the answer for yours.

The pattern we see most often splits the door opening from the working parts inside it. The association treats the opening — and sometimes the glass and frame — as a limited common element, while the operating hardware is the unit owner's: rollers, the track insert, the lock, the screen. That is exactly the half of the door that actually wears out, which is why so many owners are surprised by the first quote.

Three habits save money here. Find the maintenance clause and the unit boundary definition in your documents before you approve anything. Ask management or the board in writing rather than at the mailbox, so there is a paper trail if the split is contested later. And ask whoever quotes you to break the price out by component, so the association can see at a glance which lines are theirs and which are yours.

Condo and balcony sliders are a regular part of our week across Jensen Beach, Fort Pierce and Stuart, and we are used to working around building access and quiet hours. What we will not do is tell you what your documents say. Our condo and HOA guide explains the vocabulary — common element, limited common element, unit boundary — and the order to ask in. It is not legal advice; your association or an attorney settles the actual answer.

Seasonal homes and snowbirds: why does a door seize over an empty summer?

This is the call we take most in October and November. The door worked perfectly in April, the house sat closed all summer, and now the panel will not move at all.

Nothing swelled and nothing warped. Movement is what keeps a slider alive. Every pass of the door wipes the salt film off the rail and redistributes whatever lubricant is left around the bearing. A door that does not move for five months gets none of that — and it sits still through the hottest, wettest months of the year, which is precisely when the brine film on a bearing race does the most damage. Aluminum oxide grows into the roller housing with nothing scrubbing it back, and the track itself packs down: pollen, leaf litter and blown sand set into a crust instead of being disturbed twice a day.

Two habits change the outcome. Before you fly north, have the tracks cleaned out and the rollers checked, and leave the door locked but not forced shut against a worn seal. When you come back, vacuum the track dry before you slide anything — the ten-minute routine is the same one our technicians follow. If the door still fights you after that, stop pushing. Forcing a seized panel is how a straightforward roller job becomes a track job.

If your house sits empty for half the year, the practical pattern is a look at the doors at each end of the season rather than an emergency the week you land. Sliding door maintenance covers what that involves, and the rental and seasonal checklist covers properties that turn over between guests.

What does sliding door repair cost, and what changes the number?

Most repairs start at $275, and that figure includes parts, labor and a 1–3 year warranty on both. We would rather give you the reasoning than a range that turns out to be wrong for your door, so here is what actually moves the number once a technician is looking at it.

• Panel weight and size. An eight- or ten-foot impact panel needs heavier roller assemblies and two people to lift safely. A standard six-foot patio slider is a different job in both parts and time.
• Hardware grade. Sealed stainless rollers cost more than builder-grade nylon and last several times longer within a mile or two of salt water. On a coastal door that is not an upsell, it is the only version worth fitting.
• How long it was left. A squealing bearing is a roller job. The same door a year later is rollers plus track work, because the seized wheel has been cutting a groove in the rail the whole time.
• Parts availability. A 2003 tract slider takes a common roller pattern. A 1972 aluminum frame takes identification first and sourcing second, and that time is real.
• Access and door count. Multi-panel and pocket systems have to be sequenced out and back in. Servicing several doors in one visit costs less per door than booking several visits.

A complete quote should name the part, the labor and the warranty term rather than land on a single total. The cost guide covers how to compare quotes and what to ask back. For what it is worth, 96% of our jobs finish in one visit, and same-day service is available when a door will not close or lock.
