Unilock Windows & Doors Nationwide

Unilock Windows & Doors: The Fort Lauderdale Owner’s Guide

We stock and install Unilock-compatible windows and doors across Fort Lauderdale, with most replacement units priced between $450 and $1,200 installed depending on size, series, and whether the frame needs rework. Most standard sizes are on our truck or available next-day through our distributor network. The call usually starts with a window that won’t stay open, a door that sticks in the jamb, or a seal that’s turned chalky in the Florida sun.

In Fort Lauderdale, we see Unilock failures accelerate around the 12-year mark, especially on east-facing elevations where salt air and morning condensation cycle hard against the weatherstripping and hardware. The symptom picture is usually gradual: first the sash drifts, then the lock doesn’t bite square, then the homeowner notices the light gap or the water spot on the sill after a summer storm. By then the frame may have taken moisture, and the part swap becomes a bigger conversation.

Which Unilock Models This Applies To

Unilock’s window and door lines changed naming conventions twice in the past fifteen years, so the first step is reading the etched mark on the glass corner or the stamped label on the hinge side of the door jamb. The etched mark gives you the series (Unilock 3000, 5000, or 7000 for windows; Unilock Entry, Patio, or French door for the door lines), the manufacturing quarter, and the insulated glass unit (IGU) code. The jamb stamp on doors adds the swing, handing, and frame depth, usually 4-9/16″ or 6-9/16″ for Fort Lauderdale’s block construction with stucco.

We work with Unilock 3000 series single-hungs and sliders most often in Victoria Park and Coral Ridge, where the 2005-2015 build wave used them heavily. The 5000 series double-hung shows up in Davie and Plantation, and the 7000 casement and awning units are more common in the beach-adjacent custom builds from the same era. Door-wise, the Unilock Patio door with the older roller system (pre-2012, identifiable by the brass-colored wheel housing) is the part we replace most: the roller axle pits in salt air, the housing cracks, and the door starts jumping track.

OEM Unilock parts are available but carry a 3-4 week lead time from the regional depot in Orlando. We stock quality aftermarket equivalents from Truth Hardware and AmesburyTruth that match the critical dimensions and finish codes, with the same 10-year warranty on the part. The aftermarket roller assemblies we use have stainless axles, which matters in Fort Lauderdale more than the catalog suggests. For color-matched exterior trim or jamb extensions, we order OEM; for hardware, rollers, locks, and balances, the aftermarket route saves time without sacrificing function.

Signs Your Unilock Windows & Doors Is Failing

• The sash won’t stay up or drifts down. This is usually a failed coil balance or broken block-and-tackle in the jamb liner. On Unilock 3000 and 5000 series, the balance cartridge is concealed behind a snap-in cover; when the spring fatigues or the cord frays, the sash loses neutral buoyancy. In Fort Lauderdale’s humidity, we’ve seen balance cords mold and degrade faster than the manufacturer’s dry-climate spec suggests.
• Visible moisture or fog between the glass panes. The IGU seal has failed, allowing humid air into the argon-filled gap. Once the desiccant saturates, the fog becomes permanent. On east and south exposures in Fort Lauderdale, thermal cycling from morning sun to afternoon rain stresses the edge seal faster; we see this at 10-14 years rather than the 20-year nominal rating.
• The door sticks, scrapes, or requires shoulder pressure to latch. For Unilock Patio doors, this often traces to a cracked roller housing or a bent track. For Entry doors, it’s usually frame settlement or hinge screw loosening in the jamb, but the symptom feels identical to the homeowner. We check plumb and square first; if the frame is true, the hardware is the culprit.
• Light visible around the closed sash or door perimeter. Compression weatherstripping loses its memory in sustained heat, and Unilock’s bulb-style seals flatten out after 8-12 years in south Florida. The gap is small, maybe 1/16″, but it’s enough to let conditioned air out and driving rain in during a September storm.
• Lock tongue doesn’t engage or requires jiggling. The keeper shifts with frame movement, or the lock mechanism itself corrodes internally. On Unilock French doors, the multi-point lock system has a central gearbox and two shootbolts; when the gearbox fails, the door secures at one point only, which is a security issue, not just a convenience one.

Replacement Cost & What’s Included

For Unilock window and door part replacement in Fort Lauderdale, our installed pricing runs as follows:

What drives the range: size (a 6′ Unilock French door roller set costs more than a 3′ slider), whether the frame needs shimming or rot repair, and whether we’re matching a discontinued finish. Every quote is flat and written before work starts, under Clause 1 of the Haven Standard. The price includes the part, labor, disposal, and a documented photo record of the condition we found and the completed work. Our 365-Day Done Right Promise covers the installation; the parts themselves carry the manufacturer’s warranty, which we register and document for you.

DIY or Call Us?

There’s a short list of checks any Unilock owner can make safely: vacuum the track, lubricate the roller axle with a silicone spray (never WD-40, it attracts grit), and confirm the lock keeper screws are tight. If the sash still drifts or the door still jumps track after that, the fix involves disassembling the operating mechanism, and that’s where it goes wrong.

Unilock window balances are under spring tension; the block-and-tackle system can release suddenly if the sash isn’t supported when the jamb liner is opened. Patio door rollers require lifting a 75-150 pound panel to clear the track, and the adjustment screw access is often behind a fixed panel that needs temporary removal. We’ve been called to jobs in Fort Lauderdale where a homeowner cracked the IGU or bent the frame trying to save a service call. The documented photo record we provide shows you exactly what failed and why; the written price we give before starting means you know the number before we pick up a tool. Measure twice, write it down, then say it once.

If you’re seeing any of the symptoms above, call (754) 254-7676 to schedule your free estimate. We’ll identify the series, check the part availability, and give you a flat written price before any work begins.
