AfterCGI Windows & Doors in San Antonio, OH | TruePane Windows & Doors
We provide independent CGI our Window Installation in San Antonio and door service across San Antonio, Ohio, and the thing that sets our work apart is simple: we understand how CGI products behave when black-gumbo clay starts moving under a 1920s foundation while the afternoon sun pushes past 100°F. TruePane Windows & Doors is not a CGI dealer and we are not manufacturer-affiliated. We are the crew local homeowners call when a CGI door starts swinging open on its own or a wood-clad sash binds in a historic jamb, and we answer the phone ourselves at (888) 635-0804.
Why San Antonio Residents Choose Us for CGI Service
CGI builds a solid impact-rated window and door line, but any product installed in San Antonio’s older neighborhoods faces conditions no catalog spec sheet accounts for. Dale Kessler, our owner, grew up in Clintonville watching his father wrestle original wood frames and single-pane storms into shape on older homes, then spent close to three decades setting windows and doors across central Ohio before founding TruePane in 2008. That background matters on a CGI call in San Antonio because the work rarely stops at the unit itself. We know the framing, the flashing, the clay soil, and the paperwork. We deal with OEM CGI parts where impact ratings demand it, and we carry premium aftermarket equivalents for wear items like balance cartridges and weatherstripping that often outlast the original spec. When you call, a live person answers, and the technician who shows up has measured more historic rough openings than most crews will see in a career.
Common CGI Windows & Doors Problems We Solve in San Antonio
- Racked door frames from expansive clay. In San Antonio’s inner-city ZIP codes, the soil under the slab or pier-and-beam foundation moves with every wet-dry cycle. A CGI door installed perfectly plumb can shift 1/4 to 3/8 inch out of square within a few seasons, which is why a door that closed perfectly at install starts dragging across the threshold or swinging open by itself. We pull the casing, re-shim the jambs to true, and reset the hardware so the door works like it ought to.
- IGU seal failure on CGI 9500 Series impact windows. When a heavy impact sash is set without proper setting blocks at the corners, the glass unit flexes under its own weight in our heat. The seal fails within a few years, the panes fog, and the only real fix is a new IGU, properly blocked and set. We see this constantly in San Antonio’s older homes where original rough openings put odd pressure on new impact frames.
- Finish checking and seal failure on CGI Estate Collection wood-clad windows. San Antonio’s UV load and humidity swings are brutal on the clad-to-wood joint. Once the finish begins checking and moisture works into the seam, the cladding starts to separate from the wood substrate. On homes near the Balcones Escarpment with full afternoon exposure, this shows up in as little as five years. We repair or replace the affected sash components and address the joint properly.
- Binding sashes in clay-raked openings. The same soil movement that racks doors also squeezes window jambs out of square. A CGI double-hung or casement sash that slid smoothly at install begins binding until the homeowner needs two hands to open it. Often the solution is re-shimming the side jambs to plumb, not replacing the window. We quote the repair honestly and only recommend replacement when the sash or cladding is genuinely spent.
- Striker binding on CGI Architectural Series aluminum doors in historic homes. San Antonio’s pre-1950 homes frequently have non-standard rough openings and undersized or sagging headers above doorways. The header deflects over time, the door jamb drops a fraction of an inch, and the latch no longer finds the striker plate. The fix usually involves addressing the header movement and re-setting the jamb, not condemning the door itself.
CGI Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio’s Office of Historic Preservation requires a Certificate of Appropriateness before window or door work can legally proceed on homes in King William, Monte Vista, Government Hill, and Lavaca. That approval layer exists at a concentration Austin and Houston simply do not have, and it changes how CGI service works here in practical terms. A homeowner in King William cannot just tear out an original transom-lit doorway and drop in a new CGI Architectural Series unit and expect the city to stay quiet about it. We handle that paperwork as part of the job, because we have done it enough times to know exactly what the preservation office needs to see. Meanwhile, the Balcones Fault Zone’s expansive black-clay soils beneath those same King William and Monte Vista streets are actively racking the frames we are trying to restore or replace. Any contractor in San Antonio who ignores either force, the bureaucracy or the soil, will hand you a job that fails. We work both sides of it on the same visit. Our techs spent a morning on a 1920s Craftsman bungalow in Monte Vista whose CGI Estate double-hung sashes had bound so tightly the owner couldn’t open them after a dry summer. We popped the trim, found the jambs 5/16 inch out of square from clay heaving, re-shimmed the side jambs to plumb, and swapped the worn balance cartridges with an aftermarket upgrade rated for the sash weight. The windows now glide open even after our August heat hits 103°F.
CGI Models & Products We Service in San Antonio
Our crews work on the full CGI residential product range, including the 9500 Series impact windows, 8700 Series impact windows, Estate Collection wood-clad windows, and Architectural Series aluminum doors. For impact-rated glass and critical hardware, we source OEM CGI parts because the rating depends on it. For routine wear items like balancer cartridges, pivot hinges, and weatherstripping on older CGI lines, we stock premium aftermarket equivalents locally so San Antonio homeowners are not waiting on a shipping lead time from the coast. Our technicians carry common wear parts to most callouts, which means the typical service visit ends with the door or window working again, not a backorder notice. We are an independent service provider, so the choice between OEM and aftermarket is made the way a glazier makes it: what gives this specific unit the longest honest service life.
CGI Service Pricing in San Antonio
What you pay for CGI service in San Antonio depends on what failed, how far the framing has moved, and whether historic district paperwork applies. A basic re-shimming and balance swap on a CGI double-hung might run $250 to $450. A failed IGU replacement on a 9500 Series impact sash is typically $600 to $1,200 depending on glass size. Wood-clad Estate sash restoration runs higher because the clad-to-wood joint often needs attention beyond a surface repaint. We give every homeowner a written line-item quote before work starts, and our pricing does not change once the job is underway. Call (888) 635-0804 to schedule a free estimate, and we will tell you plainly whether your CGI component is worth repairing or has reached the point where replacement is the honest answer.

FAQs - CGI Windows & Doors in San Antonio
Yes, and we do it regularly. The key is submitting the right scope of work to San Antonio’s Office of Historic Preservation before we touch the opening, including details on what is being repaired versus replaced and how the existing character of the fenestration is preserved. We prepare and file that paperwork as part of the job, and we will not start work until the certificate is in hand. Call (888) 635-0804 and we can tell you in a few minutes whether your specific repair falls under the approval requirement.
Your door almost certainly did not fail. The ground under it moved. San Antonio’s black-gumbo clay expands and contracts with moisture, and in older neighborhoods that seasonal movement pushes door jambs 1/4 to 3/8 inch out of square. When the hinge-side jamb shifts off plumb, the door hangs slightly differently and gravity pulls it open. The fix is re-shimming the jambs to true and re-setting the hardware, not replacing the door, though if replacement is needed we also handle our Door Installation in San Antonio. We quote that repair for what it is, and it is usually a single-visit job.
For anything that affects an impact rating, we use OEM CGI parts. That includes impact-rated glass, specific glazing beads, and critical frame components. For routine wear items like balance cartridges, pivot hinges, and weatherstripping on older lines, we install premium aftermarket equivalents that often outperform the original specification and are stocked locally in San Antonio. We will tell you which parts are OEM and which are aftermarket on the written quote, and we will never substitute a generic part where the rating depends on the original.
In nearly all cases you need a new IGU for the sash, not just a single pane. Impact-rated 9500 Series windows are built as bonded double-glazed units with a laminated inner layer, and once the outer lite is compromised the entire unit has to come out and be replaced as factory-specified. We order the correct OEM IGU, swap it into the existing sash if the frame is sound, and re-set the unit with proper setting blocks so it does not fail early the way improperly blocked heavy sashes do. Call (888) 635-0804 for a precise quote on your specific sash size, and estimates are free.
It depends on whether the finish is simply weathering or the cladding has started separating from the wood at the seam. San Antonio’s UV intensity and humidity swings mean a finish can show wear in a few years, but when checking develops and moisture works into the clad-to-wood joint, you have a structural issue, not a cosmetic one. We inspect the joint, determine whether the cladding can be re-finished or the affected sash needs replacement, and depending on the age and original registration we can tell you if a warranty claim is worth filing. Call (888) 635-0804 and we will give you an honest read in one visit.
