We provide independent CGI window and door service across San Marcos, from San Marcos Window Replacement to hardware repairs on Estate, Sentry, Craftsman, and Reserve lines.

Call (254) 736-6486 for a free estimate. We’re not factory-authorized, and that’s the point – it means we recommend repair or replacement based on what’s best for your house, not a manufacturer’s quota.

Why San Marcos Residents Choose Us for CGI Service

CGI makes a serious product, but the difference between a repair that lasts and one that fails in two summers is whether the person doing it understands what San Marcos throws at a window. Our crews work on CGI products weekly, and Spencer Odell has spent nearly two decades measuring, framing, and finishing windows and doors across the Southwest. He learned the trade at Los Angeles Trade-Technical College, and he’s the one who catches the hairline gap in weatherstripping or the frame that’s a quarter-inch out of plumb – the details that show up on your energy bill six months later. A window that almost fits is a window that leaks.

We’re also local, not a call center. When you call, a person answers. When our technician arrives, you already know their name and what they look like because we send a photo before the visit. That’s the Threshold Standard – background-checked, identity-verified, photo-badged, and pre-announced before the truck pulls up. For anyone who’s ever hesitated to open the door to a stranger, that matters.

You’ll find our work on homes throughout San Marcos – and our CGI sales & service reputation is built on showing up, diagnosing honestly, and putting the price in writing before work starts, not after.

Common CGI Windows & Doors Problems We Solve in San Marcos

Here are the failure patterns we see most in this part of Texas:

• Fogged Sentry Series sliders west of town. Impact-rated laminated glass in CGI Sentry windows can develop edge seal failure after hail impacts, and in the hills off Lime Kiln Road and Ranch Road 12, that means moisture between the panes without any visible glass breakage. Homeowners notice the glass looking milky or streaked on the inside face.
• Estate Collection sash bow on east-side subdivisions. CGI’s vinyl Estate Collection windows hold up, but the west-facing elevations in subdivisions like Willow Creek and Trace see intense afternoon UV. Over years, sashes can warp or bow just enough to break the seal at the meeting rail, and you’ll feel the warm air moving through the gap.
• Sweating aluminum frames with white mineral streaks. Thermally broken frames on CGI Sentry and Reserve units can develop condensation at the thermal break. San Marcos humidity makes it worse, and those white streaks on the inside corners aren’t dirty glass – they’re mineral deposits working through the thermal break itself.
• Sticking patio doors and bound multi-point locks. San Marcos sits on expansive blackland clay, and when it shifts, door frames rack. CGI patio door rollers wear out fast on a door that’s forced open against a shifted frame, and the multi-point lock mechanism binds until the door won’t seal at all.
• Air leaks around the frame on pier-and-beam homes. That original 1960s ranch near downtown didn’t have a rigid foundation to begin with. CGI windows and doors installed in older openings where the framing has settled will leak at the corners, and the fix is usually full-frame replacement with a properly shimmed rough opening, not just a new piece of weatherstripping.

CGI Service in San Marcos: What Local Conditions Mean for Your Equipment

San Marcos sits on the Balcones Escarpment, and that single fact splits the city into two different wear patterns for CGI products. Homes west of town on limestone ledges – the ones off Lime Kiln Road, along Purgatory Creek, and up toward Wimberley – take more direct western sun and harder hail impact than the newer subdivisions east of I-35. We see the difference in our service call density: fogged Sentry sliders and bowed Estate sashes show up disproportionately on the west side, while east-side homes more often report sticking doors and gaps from clay movement. In the hills just west of San Marcos, our crew pulled a pair of CGI Sentry Series aluminum sliders from a 1980s ranch that had fogged between the panes and bowed at the header after years of August heat. We replaced them with full-frame CGI Reserve Series thermally broken units, adding new stainless rollers and a deeper sill pan, and the homeowner no longer tapes foil over the west-facing glass. If you’re wondering whether to repair or replace, the answer often depends on which side of the escarpment you live on.

CGI Models & Products We Service in San Marcos

We work on all four major CGI lines: Estate Collection vinyl single-hung and sliding windows, Sentry Series aluminum impact-resistant windows, Craftsman Series wood-clad windows and patio doors, and Reserve Series custom thermally broken aluminum windows. For hardware – locks, rollers, balances, weatherstripping – we use genuine CGI parts when they’re available, because that’s what keeps the fit and function correct. When a factory part is discontinued on an older line, we source quality aftermarket thermal breaks and seals rather than forcing a homeowner into a full replacement. We keep common CGI hardware in local inventory so a Window Repair - San Marcos doesn’t have to wait on a shipment from Florida.

FAQs – CGI Windows & Doors in San Marcos

How does San Marcos’s expansive clay soil actually damage my CGI windows and doors?
Expansive clay soil moves the rough opening, not just the house. When the soil under the corner of the foundation swells or shrinks, the frame of the window or door torques with it. On a vinyl Estate window, that gradually pulls the sash out of square until it won’t lock properly. On a Sentry or Reserve aluminum frame, it can break the sealant at the sill, allowing water behind the frame. We check for this by measuring the frame diagonals and looking for gaps between the frame and the rough opening, and that tells us whether a hardware fix or a full-frame replacement is the honest call. Call (254) 736-6486 and we’ll start with a free inspection of the frame movement.

Do CGI Estate Collection vinyl windows hold up to Hill Country UV, or do they fade and warp?
They hold up well unless they face west. Most Estate windows we service in San Marcos are on east-side houses built in the 2000s and 2010s, and the north, south, and east elevations rarely show sun damage. West-facing sashes, especially on homes with no shade from trees or a covered patio, begin showing warp or bow at the meeting rail between six and ten years, which is when the air leak and the visual sag both show up. If you feel air moving through the gap on a west-facing window, a sash replacement may be enough. If the frame itself has shifted from clay movement, a full-frame replacement is the better fix.

Can you repair a cracked impact-rated CGI Sentry Series window glass, or does the whole sash need replacing?
On a Sentry impact-rated unit, the laminated glass is manufactured to stay intact even when the outer layer cracks. If the crack is only in the outer lite and the inner lite and lamination are intact, we can often replace the insulating glass unit rather than the whole sash, which is a substantial savings. But if the edge seal has failed and moisture is building between the panes, you’re looking at an IG replacement anyway, and if the frame around that cracked glass has been sitting in San Marcos humidity, we’ll price both options and tell you which one actually makes sense. Free estimate – call (254) 736-6486.

Why do my CGI aluminum windows sweat and leave white streaks on the inside corners every summer?
It’s not your air conditioner working too hard. That condensation forms at the thermal break, the point in a thermally broken aluminum frame where an interior and exterior metal section meet. The thermal break is designed to stop heat transfer, but humid air pushing against the frame can condense right at that seam, and over time, mineral deposits build up into white streaks that look like the finish is failing. We address this by sealing the thermal break correctly and replacing the interior glazing bead if it’s cracked – and sometimes the fix is simpler than it looks, but it takes a technician who has chased this on San Marcos homes before.

Do you handle full-frame replacement of old CGI windows in San Marcos pier-and-beam homes without tearing out the interior trim?
In most cases, yes. We pull the old frame from the exterior side after removing the exterior trim, and unless the interior trim has water damage or we need extra shim access, we can preserve it. The bigger issue on pier-and-beam homes near downtown is that the rough opening is rarely square because the foundation has shifted dozens of times over the decades. We still recommend and complete full-frame replacement on these homes – we just take the time to re-shim and correct the opening before the new frame goes in, rather than forcing a window into an opening that’s a quarter-inch out of square.
