Mr-Glass Home Additions & ADU: The Pasadena Owner’s Guide
If you’re searching for a specific Mr-Glass part for your Pasadena home addition or ADU, here’s the straight answer: we match and install Mr-Glass-compatible components across most residential series, with typical installed replacement work in Pasadena running $150 to $900 depending on the part. The bigger picture on structural work, full home additions in Pasadena run $45,000 to $130,000, but individual part failures are almost always far less. Most owners discover a problem the same way: a door that suddenly binds, a panel that won’t sit flush, or glass that’s fogged between panes after a hot Pasadena summer. The part itself usually isn’t a crisis. The trick is identifying the exact replacement before the problem compounds.
Which Mr-Glass Models This Applies To
Mr-Glass parts are not universal, and that’s the first compatibility gotcha we see in Pasadena homes. The residential line breaks down by frame depth and glass unit thickness: 1/2-inch insulated units, 3/4-inch units for larger openings, and specific roller assemblies that differ between sliding door panels and fixed sidelites. The model identification is usually stamped on a metal tag along the frame edge or etched in a corner of the glass itself. If that tag is gone, we measure the glass thickness and roller wheel diameter to match the replacement, because swapping in the wrong size roller means the door will drag or jump the track within weeks.
OEM Mr-Glass parts cost more, but they’re the only choice when we’re working within an existing warranty or on a color-matched frame where a generic replacement will show. For most Pasadena homes built outside the warranty window, quality aftermarket equivalents from our regular suppliers hold up the same. We’ll tell you which is which before we order anything.

Signs Your Mr-Glass Home Additions & ADU Is Failing
- The door drags or catches mid-track. This usually means a roller wheel has flat-spotted from years of Pasadena dust getting into the bearing. A worn wheel isn’t an emergency, but every open and close is grinding the track, and the track is more expensive than the wheel.
- You hear a gritty, grinding noise when sliding. The roller bearings have lost their seal. Fine grit from our dry summers works its way in and the wheel seizes. Left alone, the wheel will stop rolling and start scraping the metal track.
- Condensation or fog appears between the glass panes. The seal on the insulated glass unit has failed. There’s no fixing a failed seal, and the longer it sits, the more likely mineral deposits etch the inside of the glass permanently.
- The door panel lifts but doesn’t release cleanly. The lock mechanism or keeper has worn loose from repeat slamming. A misaligned keeper means the door never really locks, which is a security issue on a Pasadena ADU that might sit empty during the week.
- The frame is visibly bowed or split at the corner joints. This is less common, but when we see it, it’s usually on a south- or west-facing exposure that’s taken fifteen or twenty years of direct sun. Heat expansion and contraction eventually work the corner welds loose.

AfterReplacement Cost & What’s Included
Here’s what we quote on Mr-Glass part replacements in Pasadena, installed:
- Roller wheel replacement (per panel): $150 – $350
- Track repair or replacement (short section): $200 – $600
- Lock mechanism and keeper replacement: $120 – $300
- Insulated glass unit replacement: $350 – $900
- Full door panel reinstallation with new hardware set: $500 – $1,200
The range depends on whether we’re matching an OEM color, how old the track is, and whether the frame needs realignment. You get the written price before we order a single part, so the number you approve is the number on the invoice. Every part we install is backed by our 365-Day Done Right Promise in writing: if it’s not done right, we make it right.
DIY or Call Us?
A homeowner can safely check a few things: clean the bottom track with a vacuum, wipe the glass with a soft cloth, note whether the door is square in the frame. But when a roller, spring, or glass unit fails, this is not a job to improvise. Insulated glass units are heavy, and a roller swap means lifting the panel out of the track, which is a two-person job on most Mr-Glass doors. If the wrong roller goes in, the door can drop off the track completely. If you’re in Pasadena and the part has failed, call us at (626) 657-5396. We’ll bring the right replacement and a second set of hands.
FAQs
Rollers typically last 8 to 15 years in our climate. The dry heat and fine dust in Pasadena shorten bearing life compared to coastal areas, so count on the lower end if the door is heavily used. Glass units with intact seals can last 20-plus years.
Rollers and locks are almost always replace, not repair. The internal bearings and springs are sealed units. A failed insulated glass seal cannot be repaired; the glass unit gets replaced. The track can sometimes be straightened and cleaned, but if it’s deeply scored, replacement is cheaper than fighting it.
Most Mr-Glass part replacements take 45 minutes to two hours on site. If we’re replacing an insulated glass unit, we order it ahead with the exact measurements from our first visit, so the second trip is just the install. No daylong waits.
We stock common roller sizes, lock kits, and track sections on the truck. Odd-sized glass units and specific OEM color-matched parts are special-ordered, usually with a three to seven day lead time in Pasadena. Call (626) 657-5396 and we’ll tell you what we have and what we need to order before you commit to anything.
