Mr-Glass Construction in Garland, CA | Rowan Construction Group
We provide independent Mr-Glass window and door service across Garland, from the brick-veneer ranches south of I-30 to the newer subdivisions along the northern edge. The thing that makes our work here different is simple: we are a construction company first, so when a Mr-Glass unit fails in a Garland home, we look at the slab before we look at the sash. Call (470) 298-9650 for a free estimate.
Our crews have worked on Mr-Glass 8000 Series, 9000 Series, 6000 Series sliding doors, and 7000 Series casements in hundreds of Dallas County homes. We install genuine Mr-Glass OEM components when they’re available and tell you honestly when a full replacement makes more sense than a patch job.
Why Garland Residents Choose Us for Mr-Glass Service
Grant Rowan founded Rowan Construction Group in 2007, and his background shapes how we approach every window job. He trained in construction technology at Los Angeles Trade-Technical College, where he learned framing, concrete, and estimating before ever running a paying crew. That training matters in Garland, because a Mr-Glass window sitting in a racked opening is a structural problem wearing a finish-carpentry costume.
We’re not an authorized Mr-Glass dealer, and we won’t pretend to be. We are an independent construction firm that has rebuilt and remodeled homes across Garland for close to two decades. Being independent means we can tell you the truth about parts: OEM when it protects the warranty and the seal, aftermarket when an older unit doesn’t justify factory pricing. We price the work in writing before anyone starts, and under Clause 1 of the Haven Standard, that written number is the number you pay unless you sign a change order for something different.
Common Mr-Glass Construction Problems We Solve in Garland

Here’s what we actually see on job sites here, week after week:
- Sticking or racked sashes in Mr-Glass 8000 Series windows. Central and south Garland’s brick-veneer ranches sit on unreinforced slabs that have been moving for five to seven decades. When the slab corners drop, the window frames parallelogram out of square, and the sash binds. We check flatness before touching the frame.
- Failed IGU seals in Mr-Glass 9000 Series impact units. Garland has been in the path of several major DFW hailstorms. Impact glass may stop the projectile, but repeated strikes can crack the seal around the insulated glass unit, and you get fogging between the panes. On these we install OEM IGUs whenever Mr-Glass still manufactures the size.
- Warped or bowed Mr-Glass sliding glass door tracks. Differential settlement is the culprit again. A 6000 Series door on a slab that has dropped three-quarters of an inch at one end will bind on the rollers and leak air at the meeting stile. Sometimes we can re-shim the track; sometimes the door needs full replacement.
- Brittle or cracked weatherstripping on Mr-Glass casement windows. North Texas sun is relentless, and the same clay movement that racks frames also works the gaskets until they tear. A cracked seal on a 7000 Series casement shows up as drafts first, then higher cooling bills from May through September.
- Air leakage around Mr-Glass windows isolated to one corner of the house. When only the southeast corner of a Garland home passes air, that’s a settlement signature, not a hardware fault. We document it, show you the laser-level readings, and quote the fix accordingly.

AfterMr-Glass Service in Garland: What Local Conditions Mean for Your Equipment
The thing every Garland homeowner should know before spending money on windows is this: Garland’s pre-1980 building codes did not require perimeter foundation reinforcement. So the majority of Mr-Glass windows in central Garland sit in frames on unreinforced slabs that have been heaving and settling on expansive black clay for five to seven decades. This is not true at the same rate in neighboring Mesquite or Richardson. In Garland, it’s the baseline. Our crews start every window replacement by checking slab flatness with a laser level, something rarely needed in newer northern Garland subdivisions. Measure twice, say it once, show your work. If your slab has moved a full inch at a corner, no new Mr-Glass unit, no matter how well made, will seal properly until the frame is shimmed and squared. This is the difference between a window that lasts twenty years and one that fogs in three.

FAQs - Mr-Glass Construction in Garland
How do Garland’s expansive clay soils affect Mr-Glass windows, and what do you do about it?
Expansive clay soils move seasonally, heaving after spring rains and shrinking in summer drought, which can rack window frames out of square and make Mr-Glass sashes bind. We laser-check the slab and shim or square the opening before installing new units. Call (470) 298-9650 for an inspection, and we’ll show you the readings.
Are Mr-Glass 9000 Series impact windows worth the cost in Garland after the recent hail storms?
If your home sits in the hail path that runs through Garland, the 9000 Series is worth it for the impact resistance alone, though the IGU seals can fail after repeated strikes. We’ll give you a written price for OEM IGU replacement so you can compare it against full window replacement before committing.
Can you match Mr-Glass replacement windows to my existing faded brick veneer on a 1960s Garland ranch?
We can match the frame color and glazing profile to the existing Mr-Glass unit, but we won’t promise a perfect weathering match on brick, because the brick has faded for fifty years and the new window hasn’t. We bring color sample cards to the walk-through, and we photograph the existing frame so the quoted scope is exact.
My Mr-Glass sliding door is hard to open after my slab shifted. Is it repairable or do I need a new door?
Sometimes a warped sliding door track can be re-shimmed and the rollers replaced; sometimes the door itself has bowed beyond a proper seal and needs full replacement. We’ll tell you which one your door is, and we’ll put the price in writing either way. Estimates are free.
Do you handle the permit and inspection for Mr-Glass window replacement in Garland, especially with foundation issues?
Yes. We pull permits for every window and door replacement in Garland, and when the inspector needs documentation of slab-level or structural conditions, we provide the photo record and laser readings from the visit. The documentation is standard, not an upgrade.
