Mr-Glass Home Additions & ADU: The Houston Owner’s Guide
If you’re dealing with a failed Mr-Glass home addition or ADU component in Houston, the installed replacement typically runs $45,000 to $130,000 depending on scope, structural condition, and finish level. We stock and install Mr-Glass-compatible components and can usually have a crew on-site within days, not weeks. Most Houston owners discover the problem the same way: a door that no longer closes square, visible separation at a seam, or an addition that’s pulling away from the main structure after a wet spring and a brutal summer. The Mr-Glass framing systems are solid when installed right, but Houston’s clay soil and humidity cycles put real stress on every connection point over time.
We’re Bradford Remodeling Co Houston. We are an independent service provider and not affiliated with Mr-Glass, but we work with their product lines regularly enough to know exactly what fails and why in this climate. Curtis Lane and our crews have been fixing and rebuilding Mr-Glass additions across the Houston market for over a decade, and we price this work the same way every time: straight scope, straight number.
Which Mr-Glass Models This Applies To
Mr-Glass home addition and ADU components come in a few distinct series, and the part needs differ between them. The original Mr-Glass panel systems used a 4-inch wall profile with integrated aluminum framing channels. Later series moved to a 6-inch profile with heavier gauge corner posts, which changed the connection hardware entirely. The ADU kits also use a different floor track than the home addition panels, so you cannot swap parts between the two lines even if the panel dimensions look identical at a glance.
To identify what you have, check the manufacturer label on the inside face of any door frame or corner post. You’re looking for a series code that starts with MG-AD (addition) or MG-ADU (accessory dwelling unit). If the label is faded or painted over, measure the wall thickness at any window opening: 4 inches means the original series and 6 inches means the current generation. That measurement alone tells us which replacement components we need to pull.
On the OEM versus aftermarket question, we’ll be direct. Mr-Glass OEM replacement parts are still available for most series, but lead times run four to eight weeks. Quality aftermarket equivalents, fabricated to the same extrusion specifications, are often in our Houston shop within a week. We’ll quote both and let you decide. The material spec difference is negligible for most non-structural trim and flashing components, but we always recommend OEM for the main corner posts and load-bearing headers. That’s a compatibility gotcha we’ve learned the hard way: aftermarket corner posts from a generic supplier can be off-spec by a few thousandths of an inch, and in a Houston summer that tolerance gap opens fast.

Signs Your Mr-Glass Home Additions & ADU Is Failing
- Doors that bind at the top corner or won’t latch. The foundation under the addition is shifting differentially from the main house, which is common with Houston’s expansive clay soils. The Mr-Glass frame is rigid, so any movement transfers straight to the door opening.
- Visible gaps opening at wall-to-ceiling seams. The panel connections are working loose. You’ll see this most often after a summer dry spell followed by heavy rain, when the ground rehydrates and swells unevenly under the slab.
- Condensation or staining inside wall cavities. The integrated flashing at the roof-to-wall transition has failed or was never lapped correctly. This one matters because the Mr-Glass panel cores don’t dry out on their own once saturated.
- Floor track pulling up at the threshold. The anchor bolts have corroded or sheared. We see this in additions built on unvented crawls, where Houston humidity sits at 80 percent or higher for months and eats the fasteners from below.
- Audible creaking or popping when the temperature swings. Thermal movement is normal for aluminum framing, but loud popping means the expansion joints were installed wrong or not installed at all. Over time, that stress transfers into the corner connections.

AfterReplacement Cost & What’s Included
In Houston, the installed replacement cost for Mr-Glass home addition and ADU components runs from $45,000 at the low end for a partial panel and connection repair, up to $130,000 for a full teardown and rebuild of a failing addition. The range is driven by three things: how much of the existing structure is salvageable, the finish level inside and out, and what’s hiding in the walls once we open them. We’ll give you a written price before any work starts, and that number does not move at the door.
Every replacement quote includes removal and disposal of failed components, new Mr-Glass or matched-equivalent parts, all fasteners and flashing, labor, and a written scope you can hold in your hand. We pull permits in the city of Houston and the surrounding municipalities, and we pass every inspection before we call it done. Your finished work carries our 365-Day Done Right Promise: if anything fails inside that first year, we come back and correct it at no charge. That’s the whole guarantee, in writing, on every job.
DIY or Call Us?
There’s an honest split here. An owner can safely document what’s failing, take photos of the series labels, measure the wall profile, and track when the binding gaps appear and disappear with the weather. That helps us quote accurately before we arrive. What we wouldn’t try at home is any structural disassembly of the Mr-Glass framing. Those corner posts are under real load. If one lets go while you’re working on it, you’re looking at a collapse risk and a much bigger repair bill. This is not a caulking-and-touch-up situation once the frame has moved.
If you’re in Houston and the addition or ADU is showing any of the signs above, call us at (940) 289-7658. We’ll talk through what you’re seeing, set a time to inspect it, and put a straight number in front of you before any tools come off the truck.
FAQs
With proper installation and intact flashing, the structural frame should last 30 to 40 years even in Houston’s heat and humidity. The weak points are the connection hardware and the flashing details; if those were done wrong originally, you’ll see failure signs in the first 5 to 10 years. Call (940) 289-7658 and we’ll tell you honestly which category yours falls into.
Yes, if the failure is caught early and limited to connections, flashing, or anchor points. Once the panel cores absorb moisture or the corner posts are deformed from frame racking, partial replacement becomes a temporary fix and we’ll tell you that plainly. Call (940) 289-7658 for an inspection and a straight answer on repair versus replacement.
Most partial replacements run two to three weeks on-site in Houston, and a full rebuild runs six to ten weeks depending on weather and inspection scheduling. We’ll give you a written timeline in the scope before we start. Call (940) 289-7658 and we’ll walk you through the schedule for your specific situation.
We keep common aftermarket equivalents and installation hardware in our Houston shop, and OEM Mr-Glass parts are orderable with typical lead times of four to eight weeks. We quote both paths so you can decide based on cost and timing. Call (940) 289-7658 and we’ll check current availability for your series while you’re on the phone.
