CGI Window Installation: The San Antonio Owner’s Guide
CGI window installation in San Antonio typically runs $850 to $2,400 per window installed, depending on size, frame condition, and whether you need impact-rated glass matched to an existing CGI series. We stock CGI-compatible hardware and glass packs on our trucks, so most single-unit swaps in San Antonio wrap up same-day once we confirm the model. What usually brings a homeowner to this page is a specific failure: a window that won’t seal, a crank that spins without moving the sash, or a crack that appeared after a storm and now lets humidity into the frame.
Which CGI Models This Applies To
CGI’s impact-rated product lines most common in San Antonio include the Tropic and Estate series, plus the newer Sentry casement and picture-window configurations. The gotcha: CGI changed hardware geometry between early 2010s production and current runs, so a crank assembly from a 2012 Sentry won’t always seat cleanly in a 2021 frame. We match by the white sticker on the sash edge or the etched code in the glass corner, not by memory of what a similar window looked like. OEM parts hold up marginally better in Texas sun exposure, but for hinge shoes, crank gears, and balance blocks, we’ve had equal longevity with quality aftermarket equivalents that cost 30-40% less. The decision comes down to whether the window is still under CGI’s warranty period. If it is, OEM makes sense. If it isn’t, we’ll tell you straight.
Signs Your CGI Window Installation Is Failing
- Condensation between the glass panes. The seal on the insulated glass unit (IGU) has failed. Once argon or krypton gas escapes, the window’s U-factor quietly climbs and you’re paying to cool outdoor air.
- Casement crank spins without resistance. The gear teeth inside the crank operator have stripped. This is the single most common CGI casement failure we see across San Antonio, especially on second-story windows that get daily sun on the west-facing side.
- Sash won’t stay up on a single-hung. The block-and-tackle balance has snapped. San Antonio’s dry heat accelerates the plastic bushing wear, and gravity doesn’t negotiate.
- Water staining at the bottom corners of the frame. The sill flashing or the weep holes are compromised. In San Antonio, we get short, violent downpours, and a clogged weep system turns a 20-minute rain into a trim-rot problem behind the drywall.
- Visible gap between sash and frame when closed. The weatherstripping has flattened or the hinge shoe has migrated. Either way, your air conditioning is leaking out that gap, and it’ll show up on your CPS Energy bill before you ever feel the draft.
Replacement Cost & What’s Included
In San Antonio, here’s what we price daily, installed:
- Casement crank operator (aftermarket): $180 – $320
- Crank operator (OEM CGI): $340 – $520
- IGU replacement (impact-rated, up to 36″ x 62″): $650 – $1,100
- Block-and-tackle balances (pair): $200 – $380
- Full window unit replacement with CGI-compatible frame: $1,400 – $2,400
Every one of those numbers includes parts, labor, and a written line-item price before we open a tool bag. No estimate becomes a different invoice at the door. The work is covered for 365 days, parts and labor, in writing, under the Done Right Promise. If something isn’t right, we come back and fix it, no charge and no argument.
DIY or Call Us?
You can safely do three things before calling: check the sash sticker for your model and series, clear debris from weep holes with a soft brush, and photograph the failure from a couple of angles so we know what truck stock to bring. What we recommend against is loosening any screw connected to a balance assembly or spring mechanism. A block-and-tackle balance under tension can let go fast and take fingers with it. Windows are the one place where “just watch a video first” goes sideways more than homeowners expect. If the crank spins free, the window won’t stay up, or there’s glass condensation that wasn’t there last year, call us at (903) 488-7019 and we’ll get a tech out with the right parts the first trip.
FAQs
CGI impact-rated frames can last 25 to 35 years in San Antonio, but the hardware and seals typically need replacement after 10 to 15 years of direct Texas sun and humidity cycling. We see IGUs fail earliest on west-facing elevations, which take the full afternoon sun load. Call (903) 488-7019 for a straight assessment of whether yours has life left or is costing you energy.
No. Once the seal between the panes fails and moisture gets in, the IGU has to be manufactured as a new unit and swapped into the existing frame. The good news is we can do that without replacing the whole window, which saves you $700 to $1,000 per opening. Call (903) 488-7019 and we’ll measure and quote the replacement glass pack.
A hardware swap like a crank operator or balance pair takes about an hour per window once we’re on site. A full IGU replacement runs two to three hours, mostly because the glazing bead has to be seated carefully and the frame resealed. We’ll give you a live arrival time and photo proof when the work is done, so you’re not waiting around wondering.
We carry the most common CGI crank operators, hinge shoes, block-and-tackle balances, and weatherstripping on our service trucks, so a lot of San Antonio fixes happen on the first visit. If you’ve got an unusual sash size or an older Sentry configuration, we’ll place the order and have the part within a week, usually faster. Call (903) 488-7019 with your model label handy and we’ll tell you exactly what’s on the shelf.
