Mr-Glass Windows & Doors: The Woodland Hills Owner’s Guide
If you have a Mr-Glass window or door that’s sticking, fogged, or refusing to lock, we can usually match the part and install it the same week. A full window replacement in Woodland Hills runs $4,500 to $15,000 installed, while a targeted parts repair (hinges, rollers, glass units, locking hardware) typically lands between $150 and $900 depending on what failed. Most homeowners discover the problem the hard way: a slider that suddenly takes two hands to move, a patio door that lets a draft through in December, or condensation trapped between panes that won’t wipe away.
Which Mr-Glass Models This Applies To

Mr-Glass products were sold across Southern California through several dealer networks, so there’s no single universal part number. What matters is the frame material and the glass unit dimensions. We see three main configurations in Woodland Hills homes: aluminum-frame sliders and single-hungs (common in 1970s through 1990s construction), vinyl-frame sliding patio doors, and a smaller number of wood-clad casement windows. The easiest way to identify your unit is the etched corner marking on the glass or a sticker on the interior frame edge showing the manufacturing code.
Here’s the compatibility gotcha most people miss: Mr-Glass vinyl sliders made before 2005 use a 5/8-inch roller with a pressed-in axle, while later production switched to a 3/4-inch roller with a snap-in housing. They look almost identical until you pull the door. We stock both on the truck because getting this wrong means the door binds or drops. For glass units, we match the exact overall thickness (typically 7/8-inch double-pane or 1-inch with Low-E coating) to your existing sash. OEM Mr-Glass parts are still available for some series through specialty distributors, but honest truth: the aftermarket equivalents from the same regional glass fabricators are often indistinguishable once installed, and they typically run 20 to 30 percent less. We’ll quote both and let you decide.

Signs Your Mr-Glass Windows & Doors Is Failing
- The door drags or takes real strength to slide. This is almost always a worn roller assembly. Once the nylon wheel flattens or the bearing seizes, the door’s weight rides on the aluminum track and starts gouging it. Fix the roller early and the track survives.
- Condensation or haze between the panes. The seal has failed. In Woodland Hills heat, especially on west-facing walls, sealant breaks down faster than manufacturers predicted. The glass still insulates poorly once the desiccant inside the spacer is saturated.
- The lock doesn’t catch or the handle spins without engaging. Over years, the internal gear on Mr-Glass mortise locks strips. This is a security issue, not just a nuisance. A lock that doesn’t engage means anyone can walk up and open it.
- You feel a draft around the frame even when closed. Weatherstripping on sliding units compresses permanently after about seven to ten years. The fix is a new wool pile strip and possibly adjusting the interlock.
- The window won’t stay open or slams shut when you let go. The spring balance system inside the sash has failed. On double-hungs, one side usually goes first, leaving the window crooked in the frame.

AfterReplacement Cost & What’s Included

Here’s what we see for Mr-Glass parts work in Woodland Hills, installed:
- Roller replacement (patio door): $180 – $350 per door, including both sides and track cleaning
- Insulated glass unit replacement: $250 – $650 per sash, depending on size and Low-E spec
- Lock and handle assembly: $120 – $280 installed
- Weatherstripping and interlock adjustment: $90 – $220
- Balance spring replacement (double-hung): $150 – $300 per window
- Complete vinyl window replacement: $450 – $1,200 per opening, depending on size
The range comes down to three things: sash size, whether we’re working on a first-floor or upper-floor unit, and whether the existing frame can be salvaged. We write the price before any work starts. No change orders unless you ask us to do something different. And per the Threshold Standard, every crew member is background-checked and identity-verified, and you get their name and photo before they arrive.
DIY or Call Us?
Some things are safe to check yourself. You can inspect the track for debris, try cleaning the rollers with compressed air, and confirm whether the lock engages. You can also measure your glass unit: width, height, and overall thickness. That saves time when you call.
Here’s where I’d stop if I were you. Removing a sliding patio door to change rollers means lifting 80 to 150 pounds of glass out of its frame. One wrong angle and you’ve cracked the glass or hurt yourself. Glass unit replacement requires disassembling the sash, which on older Mr-Glass frames means removing screws that have been corroding in place for thirty years. We’ve watched homeowners turn a $200 roller fix into a $900 full sash replacement by forcing something that didn’t want to move. Give us a call at (831) 290-6866 and we’ll tell you straight whether it’s a job worth doing yourself.
FAQs

In Woodland Hills, you should plan on 20 to 30 years for the frames and 15 to 20 years for the glass seals on Mr-Glass products, with west-facing units going first because of afternoon heat. Rollers and weatherstripping are wear items that need attention every 7 to 10 years. Call (831) 290-6866 and we’ll assess what’s salvageable versus what needs replacement.
No. Once the seal fails, the trapped moisture can’t be removed without disassembling the unit, and the spacer inside is already compromised. The glass gets replaced, not repaired. The good news is the frame usually doesn’t need to be. We’ve done this hundreds of times in Woodland Hills, and the existing sash is almost always reusable.
Most single-unit repairs – one roller set, one lock assembly, one glass swap – take 45 minutes to two hours. A full patio door rebuild with new rollers, weatherstripping, and track work runs half a day. We’ll confirm the window before you put a check on the calendar.
We keep the most common Mr-Glass rollers, balances, locks, and weatherstripping profiles stocked. Specialty glass units are ordered to your exact measurements from regional fabricators and typically arrive within 3 to 5 business days. We also carry compatible hardware for KraftMaid cabinets, Cambria and Silestone surfaces, so we’re set up for single-visit jobs when the parts are standard. Call (831) 290-6866 with your measurements and we’ll tell you same-day if it’s in the truck.
