Unilock Windows & Doors: The Woodland Hills Owner’s Guide
If you have a Unilock window or door with a failing lock mechanism, worn roller, cracked weather seal, or a door panel that no longer sits square, we can typically source the part and complete the repair in one visit, with most Woodland Hills jobs running between $180 and $850 installed depending on the part and what it takes to get it seated right. You’ll usually know something’s wrong when the window won’t stay up, the door rubs the frame at the bottom corner, or the lock turns but won’t catch. That’s the moment to call, because the longer these parts limp along, the more they take the surrounding frame with them.
Which Unilock Models This Applies To
Unilock’s product line spans casement windows, sliding patio doors, and hinged entry doors, and the part you need depends on which generation you own. Older Unilock sliders from the early 2000s used a single-roller carriage with a 7/8-inch wheel, while newer units run a twin-roller design that sits in a narrower track. The label sticker on the inside edge of the door panel will tell you the series number, and that’s what we need to match the part exactly. We also stock KraftMaid, Cambria, and Silestone components for the broader remodel, which matters because a door frame that needs new trim often ties into adjacent materials.
One compatibility gotcha we see regularly in Woodland Hills: Unilock multipoint lock bodies on French doors are not interchangeable across series. The gear box may look identical from the outside, but the tailpiece depth differs by 3 millimeters between the series-2 and series-4. A generic lock body from a parts bin will bind or strip within a month. OEM parts cost more, typically 30 to 50 percent more, but for locks and track rollers we recommend them. For weatherstripping and handlesets, a quality aftermarket equivalent often performs just as well at half the price, and we’ll tell you which way to go on your specific unit.

Signs Your Unilock Windows & Doors Is Failing
- The door scrapes the threshold or catches at the top corner. This usually means a lower roller has gone flat or the hinge screws have pulled out of a sagging panel. Left alone, the dragging edge wears through the weather seal and starts chewing the frame itself.
- The window drops when you let go of the crank. Unilock casement windows rely on a friction hinge that loses tension over time. A window that won’t stay open is a hinge that’s done, not a crank handle problem.
- The lock turns but the door still flexes in the wind. That’s a multipoint lock with a broken gear tooth or a disconnected shoot bolt. The handle feels engaged, but the top and bottom bolts aren’t actually driving into the frame.
- Condensation between the glass panes, not on the surface. This is a failed insulated glass seal, and it means the sash unit or the glazing bead has to be addressed. In a Woodland Hills summer, that trapped moisture turns into a permanent haze that won’t wipe off.
- The door takes effort to latch, and you have to lift the handle to get it to close. The panel has settled and the keeper is out of alignment. The part still works, but the geometry is off, and every forced closure wears the lock body a little more.

AfterReplacement Cost & What’s Included
In Woodland Hills, you’re looking at $180 to $850 installed for most Unilock window and door part replacements. A single roller swap on a sliding door runs at the bottom of that range, a multipoint lock body lands mid-range, and a full hinge set on a casement window with frame touch-up will push toward the top. Here’s how it breaks down:
- Roller or hinge replacement: $180 – $350
- Lock body or handleset replacement: $220 – $480
- Weather seal and threshold work: $150 – $400
- Insulated glass unit replacement: $300 – $850
The price you approve is the price on the invoice. We write it down before the first tool comes out, and the part cost is shown separately from labor so you know exactly what you’re paying for. Every repair carries our 365-Day Done Right Promise: if the part or the install fails within a year, we come back and make it right, no charge, no argument.
DIY or Call Us?
Here’s the honest split. You can safely confirm which part is failing by looking at the label on the door panel or window sash, measuring the roller wheel if it’s exposed, and taking a photo of the lock body with the handle removed. What you shouldn’t do is start pulling multi-point lock systems apart or removing a heavy sliding door panel from its track. Those doors weigh 80 to 160 pounds, and the spring-loaded lock cartridges are under tension. The moment they release, they take a chunk of frame or a finger with them. Our crew handles these weekly, and a misjudged DIY attempt usually costs more to fix than the original repair would have. Call (341) 217-2776 and we’ll get you a price before we even touch the door.
FAQs
You can expect 15 to 25 years from the frame and glass, but moving parts like rollers, lock bodies, and crank mechanisms typically need replacement every 7 to 12 years, especially in Woodland Hills where the dry heat accelerates plastic and rubber wear. Call (341) 217-2776 and we’ll tell you if your unit is worth repairing or nearing replacement age.
Some parts can be rebuilt, like a roller carriage with a replaceable wheel, but most Unilock lock bodies and hinge assemblies are sealed units designed to be swapped, not repaired. A repair on a sealed lock body costs more in labor than a new part costs, so we’ll always quote the replacement route.
Most single-part replacements on Unilock windows and doors are done in 45 to 90 minutes once we’re on site, as long as the part is confirmed and on the truck. If the part needs to be ordered from the manufacturer, expect a 3 to 7 business day wait, and we’ll give you that timeline when we quote.
We keep common Unilock rollers, lock bodies, weather seals, and handleset components stocked on our trucks for same-visit replacement, and we order OEM or factory-matched parts directly for anything unusual. You never have to source the part yourself, and we won’t install a part you bought online that doesn’t match the unit.
If your Unilock window or door is binding, sagging, or refusing to lock, call (341) 217-2776 now. We’ll get the right part on the truck, back it with our 365-Day Done Right Promise, and get your door working like it should before the next Santa Ana wind finds the gap.
