Unilock Windows & Doors: The Tampa Owner’s Guide
If you have a Unilock window or door with a failed hinge, worn weatherstripping, or a latch that no longer seats, we stock Unilock-compatible replacement parts and install them throughout Tampa. Installed replacement hardware for Unilock windows and doors in Tampa typically runs $250 to $1,100 depending on the part and how much disassembly the repair requires. Most owners discover the failure the hard way: a window that drops when you let go, a door you have to shoulder to close, or a whistle on windy days that wasn’t there last season.
We’re an independent service provider, not affiliated with Unilock, but we work with their hardware daily. Curtis Lane has been matching Unilock parts since well before the Tampa humidity started eating through the first wave of builder-grade components in the area. The honest reality: in Florida, Unilock products fail most often at the soft points – the weatherstripping, the corner seals, the roller assemblies, and the multi-point locking strips. The glass and frames usually outlast everything around them.
Which Unilock Models This Applies To
Unilock’s window and door lines share a common hardware platform, but there are compatibility gotchas you need to know before ordering anything. The biggest one: Unilock changed its roller housing dimensions on Series 6 and later windows, which means a roller from a Series 4 window will not fit a Series 6 frame even though the wheels look nearly identical at a glance. Always pull the sticker from the top or side of the sash frame before calling. The label will show the series number and usually the window’s manufacture date code.
For doors, the deadbolt-side latch plates on Unilock French doors from 2012 onward use a 3-point locking system that cannot be swapped with the older single-point hardware without modifying the door slab. We see this mix-up all the time from homeowners who ordered a generic aftermarket kit online and found out at 9 p.m. on a Saturday that the holes don’t line up. If you can’t read the label, measure the roller housing with a dial caliper and send us the photo – we’ll tell you in five minutes whether it’s a Series 4, 5, or 6 part.

Signs Your Unilock Windows & Doors Is Failing
- The sash drops or leans when you tilt it open. This is almost always a worn roller assembly or a broken tilt latch on double-hungs. In sliders, it’s the tandem rollers flattened on one side from years of Tampa grit grinding against the track.
- You feel a draft or hear wind at the corners. The corner seals on Unilock vinyl windows dry out under Florida UV exposure and shrink. Once the seal pulls away from the frame corner, air moves through. This is a $40 to $90 fix if caught early and a water-damage problem if ignored.
- The door latch scrapes or won’t fully engage. In Tampa’s humidity swings, door slabs expand and contract. If the latch was recently adjusted and still scrapes, the problem is usually a settled threshold or a hinge that has walked loose from the slab.
- Condensation between panes. The IGU seal has failed. Once the desiccant inside the spacer is saturated, no amount of wiping fixes it. The glass unit gets replaced, not the whole window.
- The window is harder to slide or crank than it used to be. Track gunk, old grease, and deteriorating nylon shoes make the hardware work against you. Cleaning helps sometimes, but if the shoe is cracked, the window will jump out of the track.

AfterWhat Unilock Parts Cost: Tampa Price Ranges
These are Tampa market price ranges for the most common Unilock window and door hardware repairs, including the part and our labor. Every quote we give is a written price before work starts. If our tech gets the sash out and finds something we didn’t see during the quote, we call you and get your sign-off before proceeding. The number doesn’t move at the door.
Common Unilock Repairs, Tampa Pricing
- Weatherstripping replacement (new sweep, jambs, and header strip): $120 – $320 per door
- Window sash roller replacement (both rollers, cleaned and lubricated track): $180 – $450 per sash
- Multi-point locking strip replacement for French doors: $350 – $800 per door
- Door hinge replacement (3 hinges, properly shimmed and re-aligned): $200 – $550 per door
- Single-pane IGU replacement (not the whole window – just the glass unit): $400 – $1,100 per unit depending on size and Low-E coating
- Latch and keeper replacement (entry door hardware swap): $150 – $375 per door
What drives the range: the Unilock series matters (Series 4 and 5 parts are usually cheaper and more available; Series 6 parts come from fewer suppliers and sometimes ship from out of state), whether the window is on the first or second story, and whether the old hardware comes out cleanly or puts up a fight. Every one of these jobs carries our 365-Day Done Right Promise. If the hardware we install fails within a year, we return and correct it at no charge. Written guarantee, in your hand, at close-out.
DIY or Call Us?
Some of this work is safely DIY. A window that’s just sliding rough is usually a cleaning and lubrication issue – you can remove the sash yourself on most Unilock double-hungs and sliders, clean the track with a plastic scraper, and apply a dry silicone lubricant. If you see cracked nylon, a broken tilt latch, or a roller that’s ground flat, stop there. Replacing rollers and tilt latches requires releasing spring-loaded mechanisms that can take a finger off if you’re not set up for it. Doors are the same story: weatherstripping you can peel and press in yourself; multi-point locking strips and hinges you shouldn’t.
Our advice: take the sash out if you’re comfortable, look at the hardware, take photos, and send them to us. If it’s a clean-and-lube job, we’ll tell you how to finish it yourself. If it’s not, we’ll give you a written price before we touch the window. Call (941) 655-9297.
Unilock Window & Door FAQs
The frames and glass on Unilock products routinely go 20 to 30 years in Florida weather, but the hardware and weatherstripping typically need attention every 8 to 15 years depending on sun exposure, salinity if you’re near the bay, and how often the windows get opened. Roller assemblies, tilt latches, IGU seals, and door hinges are all wear items. We see the most failures in South Tampa and Bayshore area homes where salt air accelerates the breakdown of nylon and aluminum components. Call us at (941) 655-9297 for a no-obligation look.
Simple cleaning and lubrication fixes a surprising number of problems, but a worn roller, broken tilt latch, or cracked nylon shoe is non-repairable and should be replaced. Failed IGU seals always mean glass unit replacement, not just a repair. We’ll tell you if a repair is worth chasing before we ever write an estimate for new parts. For an exact quote, reach us at (941) 655-9297 – estimates are free.
A single-window roller or weatherstripping replacement typically takes one to two hours. IGU replacement and multi-point locking strip work usually takes an afternoon. We’ll give you a realistic window before we start, and we don’t leave the job until the window opens, closes, locks, and seals the way it should. Call (941) 655-9297 for an exact quote on your Unilock part.
We stock the most common Unilock Series 4 and 5 rollers, tilt latches, weatherstripping, and door hinge sets on our trucks for Tampa service calls. Series 6 hardware and some specialty multi-point locking strips are special-order and take a few days. We also stock parts for KraftMaid, Cambria, and Silestone products if you have related work in the home.
