Unilock Windows & Doors: The Los Angeles Owner’s Guide
If you have a Unilock window or door with a failed part, we stock and install Unilock-compatible replacement hardware and glass for most models, with typical installed costs running $470 to $2,125 in Los Angeles depending on the part. Most hardware swaps are done in a single visit.
Most owners discover a problem the way you probably just did: a handle spins without catching, a roller grinds across the track, or a patio door suddenly needs a hip-check to close. That’s not a “someday” fix. A failing part wears the parts around it. We’ll match the part, quote it in writing, and install it right.
Key takeaways:
- We stock common Unilock-compatible hardware and can order model-specific parts direct.
- Installed replacement parts for windows and doors run $470 to $2,125 in Los Angeles.
- Independent provider, not affiliated with Unilock. We install their parts; we don’t sell the brand.
Which Unilock Models This Applies To
Unilock doors use a few distinct hardware generations, and the wrong part won’t just fail, it can chew up the mortise pocket. Most Unilock hinged doors take a standard multi-point lock body with a 35mm backset, while sliders run on tandem adjustable steel rollers with a 7/8-inch wheel. Measure the backset and count the locking points before you order anything. Better yet, bring us a photo of the label on the hinge edge; we’ll read it for you.
On the OEM-versus-aftermarket question: for high-wear parts like rollers and keepers, a quality aftermarket equivalent often outlasts the original. For lock bodies and espagnolette rods, we use OEM or exact-fit replacements, because a quarter-millimeter difference in the rod spacing means the door doesn’t seal against the jamb. In Los Angeles, where coastal salt air chews through zinc-plated hardware in five or six years, that seal matters more than people think.
Signs Your Unilock Windows & Doors Is Failing
- Handle feels loose or spins without resistance. The gear inside the handle hub has stripped. The door may still latch, but one firm pull from outside can pop it.
- Patio door drags or grinds on the track. The roller bearings have flattened or the nylon wheel has cracked. Dragging it only grooves the track, which turns a $60 part into a $400 rail replacement.
- Door won’t seal evenly at the top or bottom. The adjustable hinge or keeper has worked itself loose. You lose conditioned air through that gap, and in Los Angeles summers, the AC makes up for it.
- Lock points won’t all engage. One rod or roller is out of alignment. That means only one of the three locking points is actually holding the door shut.
- Visible corrosion on the hinge side. Salt air from the coast or pool chlorine does this. Once zinc hardware pits, the internal springs are next.
Replacement Cost & What’s Included
For Unilock windows and doors in Los Angeles, installed replacement parts typically run:
- Roller or hinge replacement: $470 to $885 per door
- Multi-point lock body or handle set: $590 to $1,180
- Full hardware and weather-seal refresh: $1,180 to $2,125
The range comes down to parts. A basic aftermarket roller set costs less than an OEM multi-point lock body. You get a written line-item quote before we touch the door, so the part cost, the labor, and the weatherstripping (if needed) are all on paper. Every fix is backed by our 90-Day Done Right Promise. If the part we installed fails inside 90 days, Tom Barrett comes back and makes it right.
DIY or Call Us?
What you can safely do: clean the track with a dry brush, tighten visible screws on the handle, and note the label info on the hinge edge so the part gets matched right. That’s useful. What you shouldn’t do: open a multi-point lock body if you haven’t done one before. The internal springs and gear cluster are under tension, and one slipped tool can turn a repairable lock into a full replacement. Same goes for tempered glass units in Unilock windows; that’s not a part to wrestle out alone.
If it’s a roller, a hinge, a lock body, or a keeper, call us at (877) 610-1318. We’ll identify the part, quote it in writing, and most swaps are done the same visit. No trip charge inside the county.
FAQs
Rollers and zinc-plated hardware typically last 8 to 12 years in Los Angeles, though homes within a few miles of the coast or around saltwater pools can see corrosion failures in 5 to 6 years. Hardware grade and weather exposure drive the difference more than age alone. If your parts are original and the home is 10-plus years old, call (877) 610-1318 and we’ll tell you what’s actually worn.
Most Unilock hardware parts are designed to be replaced, not rebuilt. A stripped handle hub or a flattened roller bearing can’t be reliably repaired. When a part is cleanable and adjustable, like a keeper plate, we’ll tell you that instead of selling you a part you don’t need. Call (877) 610-1318 for an honest assessment, free estimate included.
A roller or hinge replacement usually takes under an hour. A full multi-point lock body on a Unilock door can take two to three hours because the door often needs to be pulled and re-set to align the locking points. We quote the time in writing before we start, so there are no surprises. Call (877) 610-1318 to schedule.
We stock common Unilock-compatible rollers, handles, and keepers on the truck. Model-specific lock bodies and glass units are ordered direct and usually arrive within a few business days. If we need to order, we’ll tell you that on the first call and give you a written price before anything ships. Call (877) 610-1318 for a free estimate.
