Unilock Windows & Doors: The West Palm Beach Owner’s Guide
If you have a Unilock window or door with a failing part in West Palm Beach, here’s the short version: we stock most common Unilock-compatible hardware on our trucks, we install replacements the same visit, and a typical window or door part replacement runs $400 – $1,800 depending on the component and access. Most homeowners discover the problem the hard way: a window that suddenly won’t lock, a sliding door that grinds halfway, or a latch that lets salt air in overnight. You want the part matched to your exact Unilock series, not whatever the big-box store happens to carry.
We’re Elmstead Remodeling West Palm Beach, a Cedarwell company. We’re independent service providers, not affiliated with Unilock. But we’ve been matching Unilock hardware in this market long enough to know which parts fail first in Florida’s heat and humidity and which replacements actually hold up. Graham Stein walks every job site himself before a single tool comes out, and you’ll have a written price in hand before we touch the window. Put it in writing, then do exactly that.
Key Takeaways:
- We stock common Unilock-compatible rollers, locks, balances, and weatherstripping on the truck.
- Written price before any work starts, always included, never optional.
- Most Unilock window and door part replacements finish the same day.
- We’re independent, not Unilock dealers, so we match parts honestly, including quality aftermarket where it makes sense.
Which Unilock Models This Applies To
Unilock makes window and door hardware across several series lines, and not every part swaps between them. The most common Unilock windows and doors we see in West Palm Beach are the sliding patio door series with adjustable tandem rollers, single-hung and horizontal slider windows with block-and-tackle balances, and casement windows with multi-point lock sets. The hardware ranges from half-inch roller assemblies to full mortise lock bodies, and the specs differ enough that guessing causes binding, sagging, or a door that never quite seals.
To identify the right part, look for the laser-etched or foil label on the window sash or door edge; Unilock uses a two-part code with the series letter and a four-digit date. If the label is gone, we match by measuring the roller housing width, the balance channel length, and the screw spacing on the lock plate. For Unilock specifically, the OEM rollers are usually nylon-tired on steel bearings, and aftermarket equivalents in stainless or sealed-bearing versions often outlast the originals in coastal air. We’ll show you both options and the price difference before you decide.

Signs Your Unilock Windows & Doors Is Failing
- The door drags or grinds when you slide it. The roller wheels have flattened or the bearings have seized. In West Palm Beach, sand and salt air accelerate this faster than inland Florida; once the roller tire is flattened, the door rides on the track and wears grooves into it.
- The window won’t stay up when you open it. The balance springs inside the jamb have lost tension or snapped. This is common after five to eight years of heat cycling; the spring metal fatigues from repeated expansion and contraction.
- The lock turns but doesn’t secure anything. The latch tongue has worn or the keep is out of alignment. On Unilock multi-point locks, one failed hook will leave the top and bottom of the sash moving even when the handle is locked.
- You can feel air or see daylight around the frame. The weatherstripping has compressed or the door has sagged enough to pull the top corner away from the jamb. Humidity and heavy rain in West Palm Beach make this obvious quickly; the first sign is usually condensation or a mildew line on the interior sill.
- The handle is loose or flops. The internal spring or retention clip has broken inside the lock body. This is often fixable with a replacement handle set, which is a quick truck-stock item for us.
Important safety note: window balances and door springs are under constant tension. A balance that lets go while the sash is removed can send metal flying, and a door spring under load can pinch or cut. This is not a “watch a video and try it” repair. We recommend a trained technician handle anything that involves removing a sash or door panel under tension.

AfterReplacement Cost & What’s Included
For West Palm Beach, a window or door part replacement on a Unilock product typically runs $400 – $1,800 installed. The range depends on what failed: a replacement handle set is on the lower end, a full roller and track rebuild on a large sliding door sits around $1,200 – $1,800 (included in the higher end of window and door work, not the remodeling ranges). A balance replacement on a double-hung window falls between $300 – $600 per unit. Every quote includes the parts, the labor, and the clean-up.
What drives the price is access, age of the unit, and whether the failed part has worn the mating surface. A flat roller that’s been run on a bare track for a year will also need a track cap or track replacement, which adds material and time. We give you a written line-item price before any work starts; you see the part cost and the labor separately. No change orders after the crew arrives. And every Unilock part we install carries our 365-Day Done Right Promise: if it’s not right, we make it right.
DIY or Call Us?
What you can safely check: clean the track, remove debris with a vacuum, and confirm whether the door or window is visibly out of square by measuring corner to corner. That’s useful information for us and costs you nothing. What you shouldn’t do: pull a sash with a live balance, remove a door panel to inspect rollers without knowing how to release the spring tension, or force a lock that’s binding. In West Palm Beach, corrosion often welds fasteners in place; the wrong twist snaps the screw head off in the frame and turns a $150 lock swap into a jamb repair.
If the part is a handle, lock, or roller, call us at (728) 203-3270 and we’ll walk through the symptoms with you. Most of the time we can tell you over the phone whether it’s a truck-stock fix and what the written price will be before we ever pull up to your driveway.
FAQs
Rollers and weatherstripping typically last five to eight years in West Palm Beach’s salt air and humidity; lock bodies and handles last longer, often ten to fifteen years unless the door is out of alignment and wearing the hardware unevenly. Coastal homes a few blocks from the Intracoastal should expect the shorter end of every range. Call (728) 203-3270 if you want us to inspect yours and tell you exactly what’s left in it.
Sometimes. A loose handle can often be repaired with a new spring clip, and a dragging door can be adjusted by realigning the rollers, which is a repair, not a replacement. But a flattened roller wheel or a snapped balance spring has to be replaced; there’s no honest way to restore those. We’ll tell you which one you have and quote the lower-cost option whenever it exists. Free estimate, no obligation.
Most single-part replacements finish in one visit; a handle set takes under an hour, a roller replacement takes about two hours once the door panel is safely off the track, and a balance replacement on one window takes thirty to forty-five minutes. If we find additional wear while we’re in there, we’ll call you before doing anything beyond the written price. We schedule around your family’s quiet hours where possible.
We stock common Unilock-compatible rollers, lock sets, handles, and weatherstripping on our service trucks. Less common hardware, like full multi-point lock bodies for older casement windows, may take one to two days to source, and we’ll confirm the exact part and price in writing before ordering anything. We also keep parts and materials from KraftMaid, Cambria, and Silestone on hand for the remodeling side of our work.
