Andersen Sliding & Patio Doors: The Palm Beach Owner’s Guide

We stock, match, and install replacement parts and full Andersen sliding patio doors throughout Palm Beach, with most hardware swaps completed in a single visit. A typical Andersen patio door roller assembly or lock replacement runs $185 to $420 installed, while a full door replacement generally lands between $2,800 and $7,500 depending on glass package, size, and series. The way most Palm Beach homeowners discover a failing part is simple: the door starts dragging on the track, the latch stops catching cleanly, or a roller gives out with a grinding sound that was not there last season. Coastal air accelerates every one of these failures, which is why we keep the most common Andersen components on our trucks.

One thing worth saying up front: TruePane Windows & Doors is an independent service provider, not an Andersen factory branch. That independence means we can quote OEM Andersen parts and quality aftermarket equivalents side by side, on paper, so you see exactly what you are paying for before we touch the door.

Which Andersen Models This Applies To

Andersen has built sliding patio doors under several lines over the decades, and the parts are not interchangeable across all of them. The current 400 Series and 200 Series sliding doors use different roller assemblies than the older Narroline gliding doors or the Perma-Shield models that were common in Palm Beach homes built in the 1980s and 1990s. If you have a Frenchwood gliding door, that is a different hardware set again. The fastest way to identify what you have is to look at the glass etching in one corner of the door panel: Andersen etches the series name and a manufacturing code into the glass itself, and that code tells us the build date, the plant, and the exact hardware generation. No sticker, no guessing.

When it comes to OEM versus aftermarket, the decision depends on what failed. For rollers and tandem wheel assemblies, a quality aftermarket part from a supplier we trust often equals or exceeds the OEM spec at twenty to thirty percent less cost. For locks, strike plates, and weatherstripping, we recommend staying with Andersen OEM parts, because the aftermarket versions we have tested from other manufacturers do not hold their adjustment in Florida humidity the way the factory parts do. We carry both on the truck and will show you the difference in writing before you commit.

Signs Your Andersen Sliding & Patio Door Is Failing

• The door is harder to slide than it was six months ago. This almost always means the rollers have worn flat or the bearings have corroded. Palm Beach salt air works on roller bearings from the inside, even when the track looks clean.
• The door panel sits visibly lower at the handle side. That sag means the roller carriage has collapsed or the adjustment screw has stripped. A sagging panel will eventually gouge the track and then you are replacing track, not just rollers.
• The lock catches but the door still wiggles when you press on it. The latch has worn or the strike has shifted. On a coastal door, this is also how you lose your air seal and start paying for cooled air that is going out the gap.
• You hear a grinding or scraping noise mid-slide. The wheel is no longer rolling; it is being dragged. Every open and close after that is adding wear to the track itself.
• Water stains appear on the interior floor after heavy rain. The weatherstripping or the sill cap has failed. Andersen’s older sill designs can hold water that eventually works under the frame, and by the time you see the stain, the fix is more than a $20 seal.

Replacement Cost & What’s Included

For a hardware-only repair on an Andersen sliding or patio door in Palm Beach, here is the range we quote most often:

• Roller assembly replacement (per panel): $185 to $320 installed, including adjustment
• Lock and latch replacement: $145 to $260 installed
• Weatherstripping and sill seal replacement: $120 to $220 installed
• Full door panel replacement (glass and frame matched to existing opening): $2,800 to $7,500, depending on series, size, glass rating, and impact requirements

What drives the range is three things: the Andersen series you have, whether the opening needs hurricane-rated or impact glass to meet current Palm Beach code, and whether the track or frame itself has been damaged by a door that ran too long on bad rollers. Every quote we give is a fixed line-item price. The parts, the labor, and the warranty registration are written on the quote before you approve it, and the price does not change after we start. Both manufacturer warranty layers get registered in writing before our truck leaves your driveway, and the work itself is covered by our Done Right Promise.

DIY or Call Us?

Sliding door rollers and locks are not in the same danger category as garage-door springs, so let us be straight about what a homeowner can do safely. You can clean the track, vacuum the sill channel, and check the roller adjustment screws yourself. What you cannot safely do on an Andersen gliding door is lift the panel out by yourself to swap the rollers, because an Andersen door panel is heavier than it looks, and a dropped glass panel is a much larger expense than the service call. The hardware adjustment sequence on Frenchwood and Narroline doors is also unforgiving: one over-tightened screw strips the carriage, and now the fix costs more than it would have yesterday. If the door is sagging or grinding, call us at (850) 801-5596 and we will come look at it before you spend money on a part you may not need.
