Unilock Windows & Doors: The Santa Clarita Owner’s Guide
We stock and install Unilock-compatible windows and doors throughout Santa Clarita, with full replacements typically running $4,500 – $15,000 installed depending on the unit and opening. Most jobs are finished in one to two days once the part is in hand. You’ve likely landed here because a window won’t close square, a patio door drags on its track, or a seal has fogged between the panes, and you want a straight answer about whether to repair the mechanism or replace the whole unit. That’s exactly what this page covers.
Elmstead Remodeling Santa Clarita is an independent contractor, not affiliated with Unilock. We carry Unilock-compatible hardware and full units, and we also stock parts for KraftMaid, Cambria, and Silestone when a project crosses from window work into the surrounding cabinets or countertops.
Key takeaways:
- We match Unilock parts by the label sticker on the frame or sash, not by guesswork.
- You get a written price before any work starts, every time.
- Replacement hardware is usually a same-week fix; full window or door units can run one to two days on site.
Which Unilock Models This Applies To
Unilock windows and doors in Santa Clarita homes tend to fall into two families: the earlier aluminum-frame units common in Valencia and Canyon Country builds from the late 1990s through the 2000s, and the newer vinyl and fiberglass lines showing up in Saugus and Newhall remodels over the last ten years. The frames look similar from across a room, but the parts are not interchangeable. An aluminum sash block from the older line will not seat correctly in a vinyl frame, and forcing it will chew up the track.
The reliable way to identify what you have is the label. Look on the inside edge of the sash or on the head of the frame for a white or silver sticker with a series code and a date stamp. If the sticker is gone, we measure the glass thickness, the sash profile, and the track width, then match against Unilock’s spec sheets. For hardware failures like a failed hinge or a worn lock, OEM parts cost more but seat exactly. Quality aftermarket equivalents are fine for standard rollers, weatherstripping, and sweep gaskets, and we’ll tell you which is which before you spend a dollar.

Signs Your Unilock Windows & Doors Is Failing
- The window sags and scrapes the frame when you open it. This is almost always a worn hinge or a failed balance shoe, and Santa Clarita’s dry summer heat accelerates the plastic components faster than coastal air does.
- Condensation sits between the panes, not on the room side. The seal has failed and the insulating argon or krypton gas has leaked out. You can’t wipe this away; the sash or the glass unit needs replacement.
- A sliding patio door jumps off its track or grinds. The rollers under an aluminum door flatten over time, especially with the fine dust that blows through Stevenson Ranch and Castaic. Once they flatten, the door rides on the track metal itself.
- The lock no longer aligns with the strike plate. This is a frame settling issue or a worn latch, and it’s the most common reason Santa Clarita homeowners tell us a door “feels loose” even when it’s latched.
- You hear wind or feel drafts at the edges. The weatherstripping has compressed or torn. On an older Unilock unit, the bulb gasket shrinks in the heat and never recovers.

AfterReplacement Cost & What’s Included
Full window replacement in Santa Clarita runs $4,500 – $15,000 depending on how many units you’re doing, the frame material, and whether we’re retrofitting into an existing opening or cutting a new one. A single standard bedroom window typically lands toward the lower end; a multi-panel door wall or a custom powder-coated frame lands higher. Hardware-only repairs, like new rollers, hinges, or locks, are usually a fraction of that and get priced as parts plus our time.
Every quote is a written price before any work starts. That price includes the parts, the labor, the disposal of the old unit, and the hardware. We don’t add change orders once the crew is on site. And because this is covered under the 365-Day Done Right Promise, if the sash doesn’t close square or the door still drags after we leave, we come back and make it right at no charge.
DIY or Call Us?
There are a few things a homeowner can safely check. You can look at the label sticker to confirm your series, clean the track with a dry brush, and tighten visible screws on the handle. Those checks cost you ten minutes and tell us a lot when you call. What you shouldn’t do is try to pull a window sash out of the frame yourself, especially a heavy double-pane unit. The glass is heavier than it looks, and a dropped sash will take out trim, flooring, or worse. Doors with high-tension spring balances or counterweight cables are also best left to someone who works with them regularly. One misstep with a wound spring under tension is a real injury risk.
If you’re not sure whether your Unilock part is a quick swap or a full window replacement, call us at (661) 542-4056 and describe what the window or door is doing. We’ll tell you over the phone whether it sounds like hardware or a frame failure, and what that typically costs in Santa Clarita before we ever schedule a visit.
FAQs
Plan on 20 to 30 years for the frames, but the seals and hardware usually need attention around the 10 to 15 year mark because of the valley heat and dry air. A fogged sash doesn’t mean the whole window is dead; often the glass unit can be swapped while the frame stays.
Yes, in most cases the hardware, seals, and glass units can be replaced individually. The exception is when the frame itself has warped or the track is worn through, at which point replacement is the honest call. Call (661) 542-4056 and we’ll help you figure out which situation you have.
Most single-unit replacements are done in one day. A full house of windows or a large door wall typically takes two days, and we keep the work area clean with drop cloths and shoe covers from the moment the crew walks in.
We carry the common rollers, hinges, locks, and weatherstripping that cover the Unilock series most common in Santa Clarita, and we order anything unusual for delivery within the week. We’ll tell you at the estimate what’s in stock and what needs to be ordered.
