CGI Windows & Doors in Houston, OH | TruePane Windows & Doors
TruePane provides independent CGI window and door service across Houston, including the Heights, Montrose, and Woodland Heights. We are not manufacturer-affiliated, which means we tell you straight when a repair makes sense and when replacement does. What sets our Cgi specialists apart is simple: we know which CGI lines hold up to Gulf Coast humidity and which need early intervention, and we stock the parts to prove it. Call (888) 635-0804 for a free estimate.
Why Houston Residents Choose Us for CGI Service
Our shop has torn down and rebuilt more CGI window and door units in Houston’s inner loop than any independent shop we know. That is not a brag. It is what happens when a city’s climate works against window seals the way Houston’s does, and homeowners keep calling the same crew back because the fix actually held. Dale Kessler, our owner, grew up watching his father do glass work on older Columbus homes with original wood frames, and he has carried that same measuring-twice discipline into every Houston job we take. We stock CGI sash balances, corner keys, and weatherstripping locally, so we are not waiting on a distributor in another state when your window will not stay up. When you call, you get a live person, not a voicemail tree. When we arrive, the tech is background-checked, uniformed, and carrying a level he trusts more than your sill. For Houston homeowners who have been burned by a fogged seal and a contractor who stopped answering, that matters.
Common CGI Windows & Doors Problems We Solve in Houston
- Fogged Estate Collection fixed units. Houston’s dew point extremes eat butyl seals faster than any dry-climate city. We regularly see Estate Collection fixed units fog between panes within eight to ten years, and we replace the insulated glass with low-SHGC units rated below 0.25 so the new seal and the glass actually fit a Houston summer.
- Stripped Sentry Series casement operators. When Gulf gusts hit a Sentry casement with a worn operator, the sash flaps and the hardware strips. We replace operators with OEM CGI parts, not aftermarket generics that strip again in a season.
- Swollen Craftsman Series wood-clad frames. At 75 to 80 percent relative humidity, wood-clad frames swell, and sashes stick in Heights historic bungalows. We plane and seal, or we replace the sash, depending on how far the rot has gone.
- Seized Targa sliding door rollers. Post-Harvey stormwater infiltration got into a lot of Targa tracks along low-lying inner-loop blocks. Six-foot panels that will not move are usually seized rollers, and we replace them with OEM rollers and realign the track.
- HAHC permit rejections. This one is not a window failure, it is a paperwork failure. Homeowners buy off-the-shelf vinyl replacements, and the Houston Archaeological and Historical Commission rejects the submittal because the divided-lite pattern is wrong. We fix that before it costs you a permit.
CGI Service in Houston: What Local Conditions Mean for Your Equipment
There is a compliance trap in Houston that does not exist in Dallas or San Antonio. The Houston Archaeological and Historical Commission requires windows in locally designated historic districts to match the original divided-lite pattern, sight lines, and frame material. So a standard big-box double-hung fails review even if it meets energy code, and the homeowner loses the permit and eats the cost of the wrong windows. In Houston Heights and Woodland Heights, HAHC approval for CGI replacements hinges on matching original 2-over-1 divided-lite patterns. Our shop has the CGI cut sheet templates pre-approved by the commission, so we do not lose your permit to a vinyl profile that was never going to pass. On a 1930s craftsman bungalow on Bayland Avenue in Woodland Heights, our crew found the original wood double-hungs rotted at the sills and the homeowner’s CGI Estate fixed units fogged between panes. We pulled the rotted sashes, restored the original weight-and-pulley pockets to accept new CGI Craftsman Series sashes with a 2-over-1 pattern that matched HAHC submittals, and replaced the fogged Estate glass with low-SHGC insulated units, all without changing the sightlines the commission had approved. That job ran on local knowledge, not just product knowledge.
CGI Models & Products We Service in Houston
We service the full CGI residential lineup: the Estate Collection, Sentry Series, Craftsman Series, and Targa Series. Our parts approach is honest. When a unit is under 12 years old and the frame is sound, we use OEM CGI parts: balances, shootbolts, and seals sourced from CGI’s regional distributors. For older CGI or out-of-warranty units, we recommend honest replacement of the sash or full unit over chasing aftermarket parts that never fit the original extrusions correctly. We also carry the template files for HAHC submittals on historic replacement jobs, so the paperwork moves without a second trip. Our Houston customers also call us for our Window Installation in Houston, historic window restoration, and energy-efficient upgrades, and the same CGI expertise carries across all three.
CGI Service Pricing in Houston
Most CGI service in Houston falls into clear ranges. A sealed unit replacement on an Estate Collection fixed window runs $180 to $340 per sash, depending on glass size and low-SHGC coating. Sentry Series operator replacement is $145 to $260 per window. Craftsman Series sash replacement sits between $240 and $520 per sash. Targa sliding door roller replacement is $190 to $390 per panel. Full-frame tear-outs in HAHC districts run higher because the submittal and template matching add time. Every estimate is line-itemed and free. Call (888) 635-0804 and we will put it in writing before any work starts.

FAQs - CGI Windows & Doors in Houston
Yes, if the unit carries the proper design pressure rating for Harris County’s fenestration code, and we verify that rating against your specific elevation and exposure before we touch the opening. Houston enforces minimum wind pressure ratings on all windows and our Door Installation in Houston must clear the bar, and we do not install anything that does not. Call (888) 635-0804 and we will check your existing units against code.
In our Houston experience, Estate Collection fixed units fog between panes within eight to ten years, while some other premium lines hold a few years longer. The difference is butyl seal chemistry under sustained 75 to 80 percent RH. We replace fogged units with low-SHGC insulated glass so the next seal has a better chance. Call (888) 635-0804 for an exact quote.
Yes. We keep CGI cut sheet templates pre-approved by the Houston Archaeological and Historical Commission, including the 2-over-1 divided-lite patterns common to Heights bungalows. We submit the paperwork with the correct sightlines and frame profiles, so you do not lose a permit to a mismatched profile.
Stormwater infiltration rusted the rollers and left sediment in the track. We replace the rollers with OEM CGI parts, clean and realign the track, and if the frame swelled, we correct that too. A six-foot Targa panel should glide with one hand. Call (888) 635-0804 and we will diagnose it on site.
Usually it is a worn operator or a weatherstripping gap around the sash, not a warranty defect. If the unit is under warranty, we help you register the claim with CGI. If it is out of warranty, we fix it with OEM parts and it stops whistling. Estimates are free at (888) 635-0804.
