Unilock Windows & Doors: The Woodland Hills Owner’s Guide
If you have a Unilock window or door with a failing part in Woodland Hills, we stock and install Unilock-compatible windows and doors, with typical installed pricing from $4,500 to $15,000 depending on the unit and scope. Most homeowners call us after noticing a draft, a lock that no longer seats, or glass that fogs between the panes. You don’t need to know the exact part number before you call. We’ll identify it on arrival, match it to your model, and give you a written price before any work starts.
Most people discover a failing Unilock part the same way: the window that used to close with one hand now needs two, or the sliding door has started groaning halfway across the track. Heat and dry air in the Valley take a toll on seals and rollers faster than the coastal side of the hill. By the time a part announces itself, it has usually been wearing down for a year or two. The good news is Unilock parts are widely serviceable, and we keep the most common failure items on our trucks when we schedule a Unilock service call in Woodland Hills.
Which Unilock Models This Applies To
Unilock’s window and door line spans several series, and the part compatibility is less forgiving than most homeowners expect. A roller assembly for a Unilock 7000 series sliding door will not seat correctly in a 6000 series frame, even when the two doors look nearly identical from the outside. The difference is in the track profile and the mounting offset, and forcing the wrong roller in will chew up the track within months.
To identify your unit, check the corner of the sash or the edge of the door panel. Unilock stamps a small metal or foil tag with a series code, usually two letters followed by four digits. If the tag is worn or painted over, measure the visible glass width and the thickness of the sash frame. Those two numbers are enough for us to narrow the series in most cases. We also carry quality aftermarket equivalents where the OEM part is discontinued or on backorder, but we’ll tell you which one is going in and why before we order it. On Unilock specifically, the aftermarket rollers with sealed stainless bearings outperform the original nylon rollers over a California lifespan, and they cost within a few dollars of each other.
One compatibility note that trips up Woodland Hills homeowners every summer: Unilock’s dual-pane replacement sashes are not universal across their product years. A 2012-era sash will not sit airtight in a 2018 frame because Unilock changed the interlock geometry. If your sash is cracked but the frame is straight, replacement is straightforward when we match the year. If the frame has shifted, we’ll tell you honestly whether a sash-only fix is worth doing or whether full window replacement in Woodland Hills is the smarter spend.

Signs Your Unilock Windows & Doors Is Failing
- A draft you can feel with the back of your hand, even when the window is locked. This usually means the weatherseal has compressed past the point of recovery, or the sash has sagged on worn hinges so the two faces no longer meet flush. In the Santa Ana stretches, it’s the clearest early warning.
- Condensation or fog between the two panes of glass. The seal around the insulated glass unit has failed. There is no field repair for this; the IGU gets replaced as a unit. Once the seal goes, the window loses most of its insulating value, and in Woodland Hills summer heat that’s a real cost on the AC bill.
- The door drags or scrapes across the track. Rollers wear flat over time, especially on doors exposed to the fine dust that blows through the Valley. Once flat spots develop, the door weight rides on the track itself instead of the rollers, and the track starts to scrape and groove.
- The lock requires jiggling, lifting, or precise pressure to engage. The strike alignment has drifted as the panel settled or the hinges loosened. It’s a security issue as much as a convenience one. A door that doesn’t latch cleanly is a door that a good shove can open.
- The window vibrates or rattles on windy afternoons. The sash balance system has lost tension. It may still open and close, but the window is riding loose in the frame, which accelerates wear on every other moving part.

AfterReplacement Cost & What’s Included
For Unilock windows and doors in Woodland Hills, full replacement with installation runs $4,500 to $15,000 depending on unit count, series, and whether we’re doing a straight swap or rebuilding the rough opening. A single replacement sliding door typically falls between $2,000 and $6,000 installed. A single window replacement starts around $800 and climbs based on size and glass package. If the part is repairable, a roller replacement or lock swap is usually $150 to $450 including the trip, the part, and the labor.
What drives most of the price spread in Woodland Hills is the condition of the opening. Homes here run from mid-century frames that are dead-square and built like furniture to stucco openings that have moved a quarter inch over fifty years of heat and soil settling. A straight swap into a square opening is quick. A window that needs the opening flashed, shimmed, and re-caulked takes more time and material. Either way, you get a written line-item price before we start. No change orders waiting behind the drywall. Our workmanship warranty runs 365 days from the completion date, and if a repair or installation fails, the second visit is free.

| Sliding door replacement | $2,000 – $6,000 |
| Roller / lock / hardware repair | $150 – $450 |
| Impact window installation | $8,000 – $25,000 |
DIY or Call Us?
Some Unilock checks are safe and worth doing yourself. Clean the track. Clear the drain channels at the bottom of the frame. Look at the weatherseal to see if it’s torn or flattened. That kind of inspection costs you nothing and helps us diagnose faster over the phone.
Then the line gets drawn. Roller replacement means lifting a heavy glass panel out of its track, and a sliding glass door panel in a Woodland Hills home can run well over 100 pounds. The wrong move sends a sheet of tempered glass down, and that’s a hospital trip, not a YouTube moment. Sash spring balances are under constant tension, and releasing one incorrectly can take off a fingertip. Insulated glass replacement requires dealing with a unit that won’t flex and won’t forgive handling errors. Isaac Pruett has watched enough well-intentioned DIY jobs turn into a sixty-dollar fix becoming a six-hundred-dollar repair to say plainly: if the repair involves lifting glass or releasing tension, call (831) 290-6866. We’ll send a background-checked technician whose name and photo you’ll have before they arrive.
FAQs
Plan on 20 to 30 years for the frames, but expect seals and rollers to need attention at the 10- to 15-year mark, especially on west-facing exposures in Woodland Hills where the summer sun bakes the sealant. Call (831) 290-6866 if you have a unit approaching that age and we’ll inspect it before the quiet failures become visible ones.
Yes, and we’ll always price the repair first. Rollers, locks, handles, weatherseal, and balance systems are all replaceable parts when the frame and glass are still sound. The two things that can’t be field-repaired are failed insulated glass seals and structural frame rot. We’ll tell you which one you have before you spend a dollar.
Most single-unit replacements, window or door, are done the same day we arrive. Full-home window replacement in Woodland Hills usually runs two to four working days depending on the unit count and what we find in the openings. You’ll get a schedule with your written quote, and we stick to it.
We keep common Unilock rollers, locks, and weatherseal components stocked and ready, and we order series-specific items for your model before your scheduled appointment. Mason Remodeling Co Woodland Hills is an independent provider, not affiliated with Unilock, but we install and service Unilock products, and we carry parts for KraftMaid, Cambria, and Silestone jobs as well.
