PGT Sliding & Patio Doors: The Palm Beach Owner’s Guide
We stock and install PGT-compatible rollers, handles, locks, and weatherstripping for sliding glass and patio doors throughout Palm Beach, with most parts replaced same-day for $180-$480 installed depending on the hardware. Most Palm Beach homeowners call us after their door starts grinding across the track, won’t latch cleanly, or lets a ribbon of hot air in around the frame. Salt air is brutal on sliding-door hardware here, and PGT doors are no exception; the good news is that the right part, matched to the right series, gets that door gliding again in about an hour.

Key Takeaways:
- We keep PGT-compatible rollers, tandem assemblies, handles, and mortise locks on our trucks for same-day service in Palm Beach.
- Installed pricing runs $180-$480 for most parts; the roller assembly on an SGD or 500-series door is usually the culprit.
- PGT parts are series-specific. Identify your model before buying anything.
- Ed Winslow is a PGT-authorized installer, and our work carries the Done Right Promise.
Which PGT Models This Applies To
PGT makes several sliding and patio door lines, and the hardware does not swap freely between them. The most common in Palm Beach are the SGD series (SGD560, SGD570, SGD580) and the 500-series aluminum doors, though we also service PGT’s vinyl and WinGuard sliding doors on dozens of condos along South Ocean Boulevard and around the Wells Road corridor. Identifying your series matters because the roller housing depth, wheel diameter, and lock body are not universal. On most PGT doors, the model label is on the top edge of the panel or inside the frame at the operator side; a tape measure matters more than a photo. If the label is gone, we measure the roller housing, wheel profile, and door weight to pin the series down.
One compatibility gotcha we see constantly: PGT WinGuard impact doors use a heavier tandem-roller carriage than non-impact PGT sliders in the same nominal width. A homeowner installs a standard SGD roller from an online parts site, and the panel sits low, drags, and chews the new wheel in six weeks. OEM PGT hardware is what we recommend for WinGuard doors specifically; for standard PGT sliders, quality aftermarket rollers from Prime-Line or SWISCO can work well if matched correctly. We stock both.
Signs Your PGT Sliding & Patio Doors Is Failing
- The door grinds or scrapes as you slide it. The roller wheels have worn flat or the bearings are seized. Palm Beach’s fine, sandy soil migrates into the bottom track and acts like sandpaper on PGT’s nylon wheels. Running a door on flat-spotted rollers also scores the aluminum track, which turns a $40 roller swap into a $200 track replacement.
- You have to lift the door to get it moving. The panel has dropped because the roller assembly is shot or the adjuster screw is stripped. Lifting a 200-pound glass panel to clear the track is hard on your back and on the interlock weatherstripping, which starts tearing at the corner.
- The door won’t latch, or the lock binds. PGT’s mortise locks are reliable, but door sag puts the latch hook out of alignment with the strike. Ramming the handle down to force it just bends the latch and eventually strips the handle set’s internal gear.
- You feel a draft or see daylight at the top or bottom corner. On PGT sliders, this usually means the interlock weatherstripping has hardened from UV exposure and salt air, or the panel has settled enough to break the seal. Either way, the AC is leaving the room through the gap.
- The door was hit by wind or a hard slam and now jumps off the track. The anti-jump block or top guide has failed. On hurricane-rated PGT doors, this is a security issue, not just an annoyance; that door is your first line of defense when a tropical storm pushes through Palm Beach.
Replacement Cost & What’s Included
For Palm Beach, plan on $180-$480 installed for most PGT sliding-door hardware replacements. Here’s the breakdown we give on the phone before we schedule anything:
| Part | Installed Price Range |
|---|---|
| Roller assembly (per panel, standard) | $180-$260 |
| Roller assembly (WinGuard tandem, per panel) | $240-$340 |
| Handle set + mortise lock | $220-$320 |
| Weatherstripping (full perimeter) | $140-$220 |
| Track cleaning, alignment and adjust | $120-$180 |
What drives the range is the series and the panel weight. A light 500-series patio door takes a simpler roller than a WinGuard impact slider, and the part cost differs accordingly. Every quote is line-itemed before we start, so the invoice matches the number we gave you. We don’t play the change-order game. And every parts install carries our workmanship warranty under the Done Right Promise: if it’s not right, we come back and make it right.

DIY or Call Us?
You can safely check a few things yourself before calling anyone: vacuum the track, look for a model label on the panel edge, and check whether the adjuster screws at the bottom of the panel will move. What we don’t recommend is pulling a tempered or impact glass panel off the track yourself. PGT panels in Palm Beach run 150 to 300 pounds, and if that panel tips on you or the glass hits a tile floor, you’re not dealing with a $300 repair anymore. We’ve also seen stripped adjuster screws and bent frames from owners forcing panels back onto tracks they were never designed to leave. Call (561) 782-7525 and let one of our background-checked techs put hands on it. The diagnostic is free inside our home county.
FAQs
In Palm Beach’s salt air, PGT sliding-door rollers typically last 8 to 12 years before the bearings start to bind or the wheels wear flat. Doors facing the Intracoastal or the beach tend to go through rollers faster than inland doors because the salt aerosol works into the bearing grease. Listen for the grind; it tells you the roller is done before it scores the track.
Most PGT rollers are not serviceable; the sealed bearing wears, and the fix is a new roller assembly, not a repair. Mortise locks can sometimes be repaired if the latch hook is bent, but a stripped handle gear is a replacement. The good news is both are stocked on our trucks most days. Call (561) 782-7525 and we’ll tell you straight what your door needs.
A roller replacement on a PGT slider is usually a 45-to-90-minute job; a handle set and lock run about the same. Weatherstripping takes a little longer because the panel comes out to do it right. We schedule and show up, and the work’s done before lunch.
We stock the most common PGT roller assemblies, handle sets, mortise locks, and weatherstripping for the series we see in Palm Beach, and we carry quality aftermarket equivalents for non-impact doors. For uncommon WinGuard hardware, we source it overnight from PGT’s distributor network and install it as soon as it lands. A real person answers the phone at (561) 782-7525, day or night, and can tell you before you hang up whether your part is on our shelf.
