Unilock Windows & Doors: The Miami Owner’s Guide
We stock and install Unilock-compatible window and door parts across Miami, with most replacements running $5,310 – $17,700 installed depending on the unit and condition. If your Unilock product has a failed lock, warped sash, blown seal, or a door that won’t close square, we can typically match the part and schedule the work fast. Most Miami homeowners discover the problem the hard way: a window that won’t stay open, a lock that spins without catching, or a door that starts dragging against the frame after a humid stretch. Here’s what actually goes wrong and what it costs to fix properly.
Key Takeaways:
- Unilock windows and doors use specific hardware and weatherstripping that hardware-store generics rarely fit correctly.
- Miami’s heat and salt air wear out seals, rollers, and locking mechanisms faster than the national average.
- Most failed parts are replaceable without pulling the entire window or door frame.
- Written pricing before any work starts, and a 365-day guarantee on the completed job.
Which Unilock Models This Applies To
Unilock’s residential window and door lines share common hardware across several series, but there are compatibility gotchas. The locking mechanisms and hinge hardware vary between their sliding door systems, their casement lines, and their fixed picture windows. If you look at the edge of the window sash or the door hinge plate, you’ll usually find an etched model number or series code. That number matters: a Unilock series 600 lock will not interchange with a series 800 striker without modifying the jamb. We match the part to the model code, not the other way around.
OEM Unilock parts are worth the cost when the part is visible or safety-critical: locks, hinges, and latch hardware. For internal rollers, weatherstripping, and balancing hardware, quality aftermarket equivalents often perform as well or better in Miami’s humidity, and we’re honest about which is which before you spend a dollar. Mason Remodeling Co Miami is an independent service provider; we are not affiliated with Unilock, but we work with their products daily.

Signs Your Unilock Windows & Doors Is Failing
- A lock that turns but doesn’t catch. The internal cam or keeper plate has worn past its tolerance. You can sometimes adjust the keeper, but if the lock body is worn, replacement is the fix that lasts.
- A door that drags or won’t close square. In Miami, slab shift and humidity make door frames move. If the hinges are tight and the slab is still dragging, the issue is usually a bent hinge knuckle or a warped slab from moisture cycling.
- Fog between the glass panes. The seal on the insulated glass unit has failed. No repair fixes a failed seal; the glass unit gets replaced, not just cleaned.
- A window that drops when you open it. The block-and-tackle balance or constant-force spring inside the frame has broken. This is the most common Unilock window failure we see in Miami.
- Stiff crank or a casement window that won’t seal tight. The crank gear teeth strip over time, or the weatherstripping has compressed flat from years of sun and salt exposure.

AfterReplacement Cost & What’s Included
In Miami, a single Unilock window lock replacement runs $250 – $475 parts and labor. A failed door hinge or roller set typically lands between $400 and $850 installed. Full window replacements run $5,310 – $17,700 depending on size, glass package, and condition of the rough opening. Impact-rated glass changes the numbers upward, which is common for Miami homeowners upgrading to hurricane-rated units.
Every quote from us is a written price before any work starts. No verbal ballpark that grows later. The price covers the part, the labor, the cleanup, and a 365-day guarantee on the completed work. If the fix fails within a year, we return and make it right at no charge. No dispute process, no conditions. That’s how Isaac Pruett has run the crew since he started working residential builds in Miami well over a decade ago.
DIY or Call Us?
Some things you can safely check yourself: whether a lock keeper is simply loose, whether the track is filled with grit, whether a screw has backed out of a hinge plate. Tightening a loose keeper with a screwdriver is fine. Adjusting a door hinge is fine if you know which way to move it.
What we’d tell you not to touch: any lock that requires removing the internal mechanism, any window balance that involves a tensioned spring, and any glass unit replacement. A spring under tension that releases the wrong way can seriously injure a hand or face. And a failed insulated glass unit isn’t a repair job anyway; it’s a replacement. If you’re in Miami and the part is beyond a screwdriver fix, call us at (850) 780-8123 and we’ll give you a straight number on the repair.
FAQs
In Miami’s humidity and salt air, you can expect locks and weatherstripping to last 8 – 12 years, rollers 10 – 15, and insulated glass seals 10 – 20 before failure. Coastal-adjacent homes on the water lose seals faster than inland neighborhoods like Coral Gables or West Kendall. Call (850) 780-8123 if your parts are near or past that age and showing symptoms.
Sometimes. A loose keeper, a dirty track, or a misaligned strike plate can often be corrected on site without a new part. But a lock body with a worn cam or a broken window balance needs replacement; patching one is a temporary fix that fails again. We’ll tell you which situation you have, and the estimate is free.
Most single-part replacements, like a lock, roller, or hinge set, take 45 minutes to 2 hours. A full insulated glass unit swap usually takes one visit with a second visit for the new glass if it wasn’t in stock. You’ll know the schedule before we start, and Isaac Pruett’s crew finishes within that quoted window. Call (850) 780-8123 to get a timeline for your specific part.
We keep the most common Unilock lock bodies, rollers, balances, and weatherstripping on the service vehicle. For less common units or impact-rated glass, we order OEM or a matched aftermarket equivalent, usually arriving within a few days. Alongside Unilock, we also stock parts for KraftMaid, Cambria, and Silestone products. Call (850) 780-8123 and we’ll check the truck before you schedule.
