PGT Construction in Garland, CA | Rowan Construction Group
We provide independent PGT window, door, and storm-damage service across Garland’s mid-century slab homes and newer construction, with written pricing before any work starts. For homeowners just east of us, we also offer PGT service in Plano with the same upfront pricing. What makes our PGT work here different: we understand how PGT’s impact-rated assemblies respond to Garland’s expansive black clay soils, which cycle foundations inches every year, and we shim, flash, and level every PGT unit to pass the city’s structural inspection the first time. Call (470) 298-9650 for a written estimate.
Rowan Construction Group has worked on PGT windows and doors in hundreds of Garland remodels since 2007, always independent of any manufacturer program. Our Dallas PGT service follows the same independent model. That means when we quote a PGT repair or replacement, the number reflects what the job actually requires in Garland’s housing stock, not what a factory-authorized checklist says it should. We carry OEM-compatible extrusions, laminated glass packs, and roller assemblies for faster turnaround in Garland’s older neighborhoods.
Why Garland Residents Choose Us for PGT Service
Most Garland homes with PGT products are 1950s-to-1970s brick-veneer ranches sitting on slabs that have been moving for fifty to seventy years. That changes how PGT windows and doors perform, and it changes how they should be serviced. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College before spending two decades on residential and light commercial projects across Los Angeles County, and the work he’s most often called back for is structural remodels where load paths and frame geometry have shifted. PGT service in Garland is rarely just about the window; it’s about the rough opening behind it.
We also know that Garland homeowners research contractors the way they research appliances: reading the three-star reviews, wanting the price range on the page, and preferring a written scope over a phone promise. That’s exactly how we operate. Written price before work starts, signed change order before any change proceeds, documented photo record on every visit. Under Clause 1 of the Haven Standard, the number is in writing before anyone picks up a tool.
Common PGT Construction Problems We Solve in Garland

- Frame racking and sash misalignment in WinGuard aluminum windows. Decades of slab heave in central Garland pull rough openings out of square, and we regularly find corner gasket compression and corner-key shear on 1970s-era installs. The window looks like it failed; the slab underneath actually moved.
- Interlayer haze and seal delamination in older WinGuard laminated glass. Repeated hail strikes plus summer UV on unshaded south-facing walls break down the interlayer over time, leaving fogged glass that cannot be cleaned. We replace the glass pack when the frame is sound.
- Roller and track wear in SpectraGuard patio doors. On homes where the 1950s slab has settled two inches or more, the door panel binds and the lock misaligns. We inspect both the door assembly and the floor plane before recommending repair or replacement.
- Weep-hole clogging in WinGuard vinyl frames. On brick-veneer ranches where exterior repointing and stucco patches have narrowed drainage channels, clogged weep holes lead to sill rot at the bottom corners. We clear the channels and re-flash the frame to keep water moving out.
- Storm-damage assessment after DFW hail events. Garland has been inside the damage path of major North Texas hailstorms, and PGT laminated glass can carry hidden interlayer damage that isn’t visible from the ground. We document what we find with photos so you can file a claim with evidence, not guesswork.

AfterPGT Service in Garland: What Local Conditions Mean for Your Equipment
Here’s the reality of working in Garland that a generic PGT page won’t tell you. The city’s post-war industrial boom made it one of the fastest-growing U.S. cities of the 1950s and 60s, which means Garland has a dense, aging cohort of slab-on-grade tract homes now 50 to 70 years old, built directly on North Texas’s expansive black clay. Those slabs shrink during summer drought and heave after spring rains, cycling foundations multiple inches annually. Every PGT window or door replacement on a pre-1980 slab home must pass a city structural inspection that explicitly flags out-of-level sills and racked rough openings. Our crews routinely cut back masonry and add steel shims beneath PGT frames to satisfy inspectors, a step that neighboring Mesquite or Richardson projects rarely trigger because Garland’s 1950s slab stock sits on a deeper, more active clay lens. Beyond PGT work, we also handle Fence Installation - Garland properties need to account for the same shifting soils. If you own PGT windows in a central or south Garland ranch, this is the condition your install will face, and we plan for it from the first measurement.
Last spring our crew replaced a set of fogged PGT WinGuard casement windows on a brick ranch off Saturn Road near downtown Garland, where the master bedroom slab had settled 1.5 inches. We pulled the old aluminum sashes, found the original rough openings out of square by nearly half an inch, then shimmed and flashed the new PGT laminated units to sit perfectly level before the city inspector walked the job. The homeowner now opens those windows with two fingers instead of a pry bar. Measure twice, say it once, show your work.
PGT Models & Products We Service in Garland

We work on PGT PGT sales & service product lines across Garland: WinGuard Vinyl impact windows, WinGuard Aluminum impact windows, SpectraGuard sliding glass doors, and Eze-Breeze porch enclosure panels. For repairs, we prefer OEM extrusions, laminated glass packs, and roller assemblies to preserve the original structural and wind-load ratings. But when a door’s geometry has shifted due to slab settlement, we honestly advise replacement with a properly shimmed PGT unit rather than grinding tracks to fit, because the old frame will leak air and fail a future windstorm inspection. We keep common PGT components available locally for faster Garland turnaround, and anything we don’t stock we order with a written lead time on the estimate.

FAQs - PGT Construction in Garland
Yes. On Garland’s shifting clay, we cut back masonry, add steel shims beneath the PGT frame, and flash the opening to allow independent movement between the frame and the brick veneer. Standard flashing that works on stable soil will bind and tear here within a few seasonal cycles. Call (470) 298-9650 and we’ll put the approach in writing with your estimate.
We can replace the glass pack in most cases, provided the frame is square and the corner keys are intact. If slab movement has racked the frame, a new glass pack will fail early, and we’ll tell you that before you spend the money. Estimates are free at (470) 298-9650.
Garland does not mandate impact-rated glazing retroactively on existing homes. However, Dallas County energy codes and Texas Windstorm requirements apply when you replace windows, and PGT WinGuard units meet both while also handling hail better than standard glass. We’ll spec what your specific zone requires, in writing, before any work starts.
First we measure the floor plane and the frame geometry to determine how far the slab has moved. If the door is repairable, we replace rollers and tracks and adjust the lock. If the frame has racked, we recommend a properly shimmed replacement PGT unit rather than forcing the old door to work. Call (470) 298-9650 for an exact quote on your door.
Yes, but only after we verify the patio cover structure and roof deck can carry the new panel load. On older Garland homes with slab movement, we often add lateral bracing first so the Eze-Breeze panels don’t bind when the house settles through another wet spring. The written quote covers both the bracing and the panel install, with no change order unless you sign one.
