Unilock Windows & Doors: The South Florida Owner’s Guide

Unilock window and door replacement in South Florida typically runs $4,500-$15,000 for a full window replacement project and $8,000-$25,000 for impact-rated installations, with most hardware and component repairs completed same-day. We stock Unilock-compatible hardware, weatherstripping, and locking assemblies on our trucks throughout Broward, Miami-Dade, and Palm Beach counties. Most South Florida homeowners realize their Unilock unit is failing when the crank handle spins without moving the sash, or when they notice daylight bleeding through a closed window frame after a storm season.

Which Unilock Models This Applies To

Unilock manufactured several window and door lines before shifting focus primarily to hardscape products, so identifying your exact series matters before ordering any part. The most common Unilock window hardware we encounter in South Florida homes falls into the 1990s-2000s-era tilt-turn and casement lines, often labeled with a small embossed “U” logo and a four-digit model stamp on the hinge jamb or head track.

Check the top of the sash or the edge of the frame for a metal rating label; if that’s gone, measure the visible glass dimensions and the overall frame depth. Unilock casement operators typically used 9-inch or 15-inch arm lengths depending on sash width, and mixing these up leaves you with a window that won’t seal tight. We carry both OEM-spec and quality aftermarket equivalents; for discontinued Unilock lines, the aftermarket hardware often outlasts the original because the zinc alloys improved after 2005. If your home is in Coral Gables or Weston and was built during the 1995-2005 boom, we’ve probably serviced your exact hardware before.

Signs Your Unilock Windows & Doors Is Failing

• Crank handle spins freely without moving the sash. The operator gear set has stripped, usually from corrosion in the gearbox after years of South Florida humidity. The gears are brass or zinc, and once the teeth round off, the handle turns but nothing catches.
• Window won’t latch fully or pops open in wind. The locking cam or keep has worn down, or the frame has settled slightly and the strike no longer aligns. In coastal South Florida, salt air accelerates the wear on these small metal components.
• Visible gap between sash and frame when closed. The hinge arm has bent or the weatherstripping has compressed permanently. Hurricane pressure cycles from seasonal storms slowly fatigue the metal, especially on east-facing windows in Hollywood or Fort Lauderdale.
• Condensation between double-pane glass. The insulated glass unit seal has failed. In South Florida’s heat, this happens faster than in northern climates; once moisture enters, the Low-E coating degrades and your cooling load rises.
• Sash drags or sticks during operation. The track rollers have flattened or the balance shoe has cracked. Unilock’s older vinyl windows used a specific balance shoe width that doesn’t cross over to other brands without adapter kits.

Replacement Cost & What’s Included

For Unilock component repair and hardware replacement in South Florida, most homeowners fall in the $450-$1,200 range per window depending on what’s actually failing. A full window replacement runs $4,500-$15,000 for standard vinyl or aluminum units, while impact-rated Unilock-compatible replacements for hurricane zones run $8,000-$25,000 for a typical home.

What drives the spread: operator assemblies and lock sets are on the lower end; sealed glass unit replacement sits in the middle; full frame-and-sash replacement with impact glass tops the range. Our quotes separate parts from labor so you see exactly where your money goes. We don’t mark up hardware, and we don’t swap out entire windows when a $90 operator fixes the problem. Every installation we perform carries our workmanship warranty, and impact-rated products include the manufacturer’s own glass breakage coverage.

DIY or Call Us?

You can safely inspect your Unilock hardware without tools: open the sash fully, look for rust on the operator arm, and wiggle the lock to feel for slop. If the glass is cracked or the unit is impact-rated, stop there. Impact window glass is under tension and the laminated layers are heavy; a dropped sash can shatter inward or pinch fingers badly.

Where DIY goes wrong: homeowners often strip the operator screws trying to force a frozen gearbox, or they order the wrong arm length and chew up the sash track trying to make it fit. We’ve rescued plenty of “almost fixed” windows in Pembroke Pines and Boca Raton where a $12 part turned into a $400 sash replacement. Do it right the first time or you’ll do it twice - and the second time always costs more. Call (844) 665-0162 and we’ll bring the correct part, check the full unit while we’re there, and warranty the work.
