CGI Door Installation: The San Antonio Owner’s Guide
CGI door installation in San Antonio typically runs $450 to $1,850 per door depending on whether we’re replacing just the slab, the hardware, or the full frame-and-threshold assembly. We keep common CGI hinge sets, sweep kits, and threshold components on our trucks, so a straightforward part-for-part swap is usually done in a single visit. Most San Antonio homeowners discover a problem the hard way: a door that suddenly drags against the threshold, a latch that no longer catches, or daylight visible along the top edge after a hard windstorm.
What makes CGI different from most door brands on the market is the engineering behind the frame. These are impact-rated doors built for coastal wind zones, and that changes how we approach installation. A CGI door isn’t forgiving when a part wears out, because the failure tends to cascade. A worn hinge puts extra load on the strike plate, which loosens, which lets the door sag, which compromises the weather seal. Fix one thing at a time and you’ll be back in a year. That’s why we quote the full repair picture up front.
Which CGI Models This Applies To
We install and service door components across CGI’s residential impact line, including the Estate Collection, the Classic Collection, and the heavier Santiago series doors common on newer San Antonio builds. The compatibility gotcha most owners run into: CGI uses a proprietary hinge pattern on several models that doesn’t line up with off-the-shelf hinges from big-box stores. You can’t just grab a 4-inch hinge at Home Depot and expect the door to hang right.
Here’s how to identify what you have. Open the door and look at the hinge edge of the slab. CGI stamps the series name and a manufacturing code into the metal near the top hinge. That code tells us the exact hinge spacing, reveal tolerance, and whether your door takes the standard sweep or the heavy-gauge commercial sweep. If the stamp is painted over or worn, we measure the hinge-to-hinge distance and the slab thickness on site. We usually recommend OEM CGI parts when the door is under warranty or when it’s a load-bearing entry door that takes daily San Antonio sun and the occasional Gulf-driven storm. For interior or rarely used doors, a quality aftermarket equivalent with the same gauge steel does the job at about 60 to 70 percent of the OEM price, and we’ll tell you when that’s the smarter call.
One thing worth knowing: CGI doors built before roughly 2015 used a slightly different threshold profile than current production. If your door predates that and the threshold is worn, we’ll check the underside of the slab before quoting, because the newer threshold may require a minor shim adjustment to keep the reveal consistent. That’s the kind of detail that prevents a door from whistling on windy nights.
Signs Your CGI Door Installation Is Failing
- Dragging or scraping at the threshold. This usually means the bottom sweep has worn down or the hinges have developed enough play to let the slab settle. On a CGI door with impact-rated weight, that settling accelerates once it starts.
- Latch won’t catch without lifting or pulling the door. Classic hinge wear symptom. The fix may be as simple as re-shimming one hinge, but if the strike plate has wallowed out, the door needs realignment and possibly a new reinforced strike.
- Visible light or airflow along the top or latch edge. The weatherstripping has compressed or the door has shifted out of square. In San Antonio summers, this is also your air-conditioning money escaping.
- Water staining at the bottom corners after heavy rain. Your threshold seal or corner pads are failing. This is more common on west-facing doors in San Antonio that get baked by afternoon sun, which hardens the rubber faster than expected.
- Squeaking that gets louder, not quieter, with lubrication. On heavy impact doors, a persistent hinge squeal often means the hinge pin itself is bending under load. Lubrication masks it for a few days, then it comes back worse.
If you’re seeing two or more of these at once, the door has likely shifted and the problem is compounding. Sean Mackey and our crew see this pattern regularly on San Antonio homes where the clay soil expands and contracts enough to subtly move the rough opening over time. The frame may have been perfectly square when it went in and is now out by a quarter inch, and no new sweep alone will fix that.
Replacement Cost & What’s Included
Here’s what our CGI door installation and component replacement work costs in San Antonio, installed:
| Job | Installed price range |
|---|---|
| Hinge set replacement (full door, 3-4 hinges) | $180 – $340 |
| Bottom sweep + threshold seal | $140 – $260 |
| Full threshold replacement | $380 – $650 |
| Strike plate + realignment | $120 – $220 |
| Full slab swap (same opening, reusing existing frame) | $850 – $1,850 |
The range depends on your CGI series, whether we’re using OEM or aftermarket components, and whether the rough opening needs correction. Every quote is a written line-item price before we start, no surprises at the end. And the work is covered by our 365-Day Done Right Promise: if it’s not right, we make it right, parts and labor, in writing, for a full year. You’ll also get the Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos, and a digital invoice you can pay from your phone.
DIY or Call Us?
For CGI door components, here’s the honest split. There are a few things you can safely check yourself: tighten visible hinge screws (use a #3 Phillips, not a drill), inspect the sweep for visible tearing, and confirm whether the latch plate screws are loose. That’s diagnosis, not repair, and it helps you describe the problem accurately when you call us.
The DIY part is where we pump the brakes. A full-size CGI impact door weighs 180 pounds or more depending on the series. Pulling hinge pins on a door that heavy without proper support is genuinely dangerous, and re-hanging it so the reveal is even is finicky work. If the frame has shifted at all, no amount of hinge fiddling will square it. We’re also independent of CGI and stock components specifically matched to their series, so we’re not guessing at compatibility. Call us at (903) 488-7019, tell us what the door is doing, and we’ll give you a straight answer about what it’ll take. If the numbers don’t make sense on paper, we’ll tell you that too.
FAQ: CGI Door Installation in San Antonio
On a San Antonio home, expect a bottom sweep to last 3 to 5 years before sun and heat hardening compromises the seal. Hinges on properly installed doors commonly last 10 to 15 years, but the intense afternoon sun on west and south exposures accelerates wear on any rubber or polymer component. Call (903) 488-7019 if your sweep has gone stiff and brittle; that’s a sign the rest of the seal package isn’t far behind.
Some hinges can be re-pinned and some strikes re-set, but most worn sweeps, thresholds, and seal components are replace-only parts by design. When we inspect a door, we’ll tell you what can be saved and what can’t, and the written quote reflects exactly that. Call (903) 488-7019 for a free assessment of what your door actually needs.
A sweep or hinge replacement is typically a 1 to 2 hour job on site, and we do it in one visit. A full slab swap with threshold work usually takes half a day. We schedule a live arrival window so you’re not waiting around, and if anything changes, you’ll see it in real time. Call (903) 488-7019 to schedule.
We stock common CGI hinge sets, sweeps, strike plates, and threshold components on our trucks, matched to the most common series we see around San Antonio. Uncommon sizes or specialty finishes are ordered direct and typically arrive within 3 to 5 business days. Call (903) 488-7019 with your door’s model code and we’ll tell you right then whether we’ve got it on hand.
