Unilock Windows & Doors: The Long Beach Owner’s Guide
If you have a Unilock window or door with a failed lock, hinge, roller, or weather seal, we stock and install Unilock-compatible replacement parts across Long Beach, with most repairs running $250 – $700 for parts and labor, depending on the hardware and how much disassembly the job requires. You don’t need to rip out the whole window or door. The failure is usually one component, and the fix is faster and cheaper than you’d expect. Most owners discover the problem the same way: a window that won’t stay open, a door that drags or won’t latch, or a lock that spins without grabbing.
Sawyer Remodel Long Beach is an independent service provider. We’re not affiliated with Unilock, but we’ve worked on enough Unilock product across Long Beach to know which parts fail, which aftermarket equivalents hold up, and when you should insist on OEM.
Which Unilock Models This Applies To
Unilock built windows and patio doors across several lines over the years, and the part you need depends on the series, the year of manufacture, and the frame material. The most common Unilock products we service in Long Beach are vinyl horizontal sliders, single-hung and double-hung windows, and sliding patio doors. The parts that come up most are spring balances on single-hungs, roller assemblies on sliders, multi-point lock gearboxes on patio doors, and compression weather seals along the sash frames.
Here’s the compatibility gotcha most people miss: Unilock spring balances are length-specific and weight-rated. You cannot swap in a balance from another brand just because it looks close. The balance is stamped with a code on the side of the tube or the shoe; that code tells you the poundage and the length. A Long Beach home with aluminum-frame Unilock windows from the late 1980s uses a different balance than a vinyl Unilock from 2005, even if the window width is the same. Aftermarket balances exist and can save you 30 – 40% over OEM, but only when the spec matches exactly. For multi-point lock gearboxes, we recommend OEM or a known-equivalent gearbox because the bolt spacing has to line up with the keepers already mortised into the door edge.
If you can find the label, great. It’s usually etched on the spacer bar between the glass panes or on a sticker along the frame edge. If the label’s gone, remove the sash and check the hardware itself: the balance tube, roller housing, or lock body will carry a manufacturer stamp or a length measurement you can match. When in doubt, bring the old part to the counter or send us a photo. We’d rather match it once than order twice.
Styles & brands we work with
Signs Your Unilock Windows & Doors Is Failing
- The sash won’t stay up, or it’s fighting you when you try to open it. This is a spring balance failure on a single-hung or double-hung. The balance is a tensioned spring inside a channel; when it gives out, the window loses its counterweight and drops or binds.
- A slider grinds, drags, or feels like it’s rolling over gravel. The roller assemblies on the bottom of the sash are shot. Unilock rollers on Long Beach homes often fail from years of salt air and fine grit working into the bearings, especially anywhere within a few miles of the water.
- The door handle turns but the locking points don’t move, or the door won’t fully secure. This is the multi-point lock gearbox. It’s the single most common patio door failure we see on any brand, not just Unilock. The gears strip over time and the handle spins free.
- You can feel a draft, or the door doesn’t seal evenly when it closes. The weatherstrip along the sash or panel has compressed or torn. On a Unilock door that’s 15 years old, the bulb seal on the sliding panel loses its shape and the door starts letting Long Beach’s damp air through.
- The door won’t lock at all, or the latch bolt won’t extend far enough to catch. The door slab has settled or the hinges have worn, pulling the latch out of alignment. Sometimes it’s the keeper, sometimes it’s the hinge bushing. The fix is usually a hinge replacement or a keeper adjustment, not a whole new door.

AfterReplacement Cost & What’s Included
Here’s what we charge in Long Beach for the most common Unilock window and door repairs. These are installed prices: the part, the labor, and the service call, all in writing before we start.
- Spring balance replacement: $250 – $450 per window, depending on whether it’s one or both balances and the weight rating.
- Roller assembly replacement on a slider: $200 – $400 per panel.
- Multi-point lock gearbox replacement on a patio door: $350 – $600, depending on whether the lock body and strike plates both need replacing.
- Weather seal replacement around a door or window sash: $150 – $350, materials included.
- Hinge replacement or door realignment: $200 – $450.
The range comes down to two things: whether the part is OEM or a matched aftermarket equivalent, and how much labor the disassembly takes. A balance swap on a double-hung takes about 45 minutes if the window is accessible; a multi-point gearbox on a patio door can take two hours because the whole lock rail comes apart. Either way, you get the price in writing before we remove a screw, and the number on the invoice is the number you approved. Every repair carries our 365-Day Done Right Promise: if it’s not done right, we make it right, backed in writing.
DIY or Call Us?
For windows and doors, a lot of the diagnostics are safe to do yourself. Check whether the sash sags. Look at the roller. See if the keepers line up. That part costs you nothing but five minutes with a flashlight. For spring balances though, here’s where we tell you flat out: these are coiled, tensioned springs, and removing one without the right technique can send the sash flying or slice a hand open. We’ve seen it. If the window is stuck in the up position and won’t come down evenly, don’t force it. Call us. Same goes for a multi-point lock gearbox: by the time you’ve drilled out the faceplate and pulled the gearbox, you’ve spent an hour and you still need the right part. That’s the point where a $400 repair beats a $150 mistake that costs you the whole door. Call (562) 512-6480 and we’ll price it over the phone before we even roll a truck.
FAQs
In Long Beach’s salt air, Unilock window frames can last 20 to 30 years if they’re maintained, but the moving hardware rarely does: spring balances typically last 8 to 12 years, roller assemblies 10 to 15, and multi-point lock gearboxes 12 to 18 years before the gears strip or the springs fatigue. The coastal moisture accelerates corrosion on the hardware even when the vinyl or aluminum frame looks fine.
Sometimes. A hinge can be tightened. A keeper can be shimmed. A balance shoe can be repositioned. But once a spring balance loses tension or a gearbox strips its internal gears, there’s no honest repair. The part gets replaced. We never quote a repair on a part that’s at the end of its life, because that’s just charging you twice.
Most single-part replacements – a balance, a roller, a weather seal – are done in 45 minutes to two hours. A multi-point lock gearbox with strike plate work can run two to three hours. We’ll give you the time window before we start, and you get before-and-after photos while we work.
We stock the common Unilock-compatible parts on the truck: standard spring balance sizes, roller assemblies for sliders, multi-point lock gearboxes, and compression weather seals. For unusual sizes or older aluminum-frame Unilock, we may need one order cycle. Call (562) 512-6480 with the window model or a photo of the old part and we’ll tell you if it’s on the truck or needs to be ordered. Estimates are free.
