CGI Door Installation Nationwide

CGI Door Installation: The Houston Owner’s Guide

CGI door installation in Houston typically runs $1,100 to $2,800 installed for a full door slab replacement, depending on the series, size, and hardware you’re matching. Most owners call us after a failed latch, a sagging hinge, or a panel that no longer seals against Houston humidity, only to find the fix costs close to a new door. The short version: if your CGI door is more than 8 years old and the frame or lock mechanism has failed, replacement is usually the smarter money. We stock CGI-compatible parts and doors on our trucks, and most swaps in the Houston area take half a day once the new unit is on hand.

Here’s the pattern we see over and over across Houston, from Katy to Clear Lake: a door that worked fine for years starts sticking in June, when humidity swells the frame. Homeowners lubricate the latch, adjust the strike plate, maybe replace the weatherstripping. It helps for a few weeks. Then the door starts binding again, and by August it won’t latch without a shoulder. That’s when the phone rings. The part didn’t fail suddenly in most cases. It wore down a little at a time until the cheap fix stopped being worth it.

We are an independent installer, not a CGI factory service provider. That means we can quote you parts and labor honestly, match aftermarket hardware when it makes sense, and install the door the same way whether you bought the slab from us or already have it sitting in your garage.

Which CGI Models This Applies To

CGI has built doors under a few distinct series over the years, and the installation details differ more than most people expect. The older Estate and Classic lines used a thinner extruded aluminum frame and a narrower stile profile, which means a replacement slab from the current Sentry or Tribute series won’t always drop into the old frame without shimming and re-machining the hinge mortises. The current production CGI doors, including the Sentry impact-rated series common in Houston coastal and flood-zone construction, use a beefier frame extrusion and a multi-point lock body that requires a specific prep pattern in the slab.

Here’s the compatibility gotcha we run into at least twice a month in Houston: a homeowner orders a replacement door slab based on the rough opening size alone, and the new slab arrives with hinge locations that don’t match the existing frame. Rough opening measurements get you close. But CGI doors are built to order with hinge prep matched to the frame, not to a generic template. If you’re replacing the slab only, we measure the hinge-to-hinge spacing on the existing frame to the sixteenth of an inch before we order. If you’re replacing frame and all, we measure the rough opening in three places and order to the widest point, then shim and seal to close the gap.

For OEM versus aftermarket: on the door slab itself, OEM is the only sensible choice for impact-rated units. The glass, the frame, and the slab are engineered and tested as a system. Swapping in a generic slab voids the wind-borne debris rating and, frankly, doesn’t save enough money to justify it. Where aftermarket parts make real sense is hardware: rollers, hinges, lock bodies, and weatherstripping. Quality aftermarket lock bodies from brands like Hoppe or Truth can match or beat the OEM part for half the money, and we’ll tell you which is which before you spend a dollar.

Signs Your CGI Door Installation Is Failing

• The door drags or sticks on the threshold. This is almost always frame settlement plus Houston’s humidity cycle. The aluminum frame expands and contracts, the threshold screws loosen, and the slab starts riding on the sill instead of clearing it. If it’s been dragging for more than a season, the threshold is typically worn past adjustment.
• The deadbolt won’t throw without lifting the handle. That means the actuator or lock body inside the door has worn enough that the bolt no longer lines up with the strike plate. On CGI multi-point locks, this is the first sign the gearbox is on its way out, and it only gets worse.
• Water stains at the bottom corners of the interior frame. The sill pan or the door sweep has failed, and Houston rain is finding its way under the threshold. By the time you see the stain, the subfloor around that corner has been wet for a while. This is not a caulk-and-paint fix.
• Visible daylight around the weatherstripping. Hold a flashlight on the outside of the closed door at night and look from inside. If you see light, you’re losing conditioned air every hour the HVAC runs. On a Houston summer day, that gap is also letting in humid air that the slab and frame have to handle.
• The door sags when it’s open. On hinged CGI doors, sagging means the top hinge screws have stripped out of the frame or the jamb has twisted. Shim plates and longer screws will buy you a few months. A proper fix means resetting the door in the frame or replacing the frame entirely.

Replacement Cost & What’s Included

Installed CGI door replacement in Houston runs between $1,100 and $2,800 for most hinged single doors, with the majority landing around $1,600 to $2,200. Slab-only replacements run $500 to $1,200 when the existing frame is sound. Full frame replacements, which we recommend when there’s water intrusion or the frame has twisted, add $400 to $700 over slab-only pricing. Sliding CGI doors, which are a different animal entirely, run $2,500 to $4,500 installed depending on width and glass package.

What drives the range: the door series, whether the glass is impact-rated or standard insulated, the finish on the hardware, and how much of the existing frame we can reuse. Every quote we write in Houston is line-itemed, so you’ll see the slab, the hardware, the labor, and the haul-away as separate numbers. We hand you that written price before any work starts, and it doesn’t change at the door. Our workmanship warranty covers the installation for a full year, and if something we installed fails inside that year, we come back and fix it at no charge. That’s the Kingswell Guarantee, and it’s written on every quote.

DIY or Call Us?

There are a few things worth checking yourself before you call anyone. Tighten the hinge screws. Look for a loose strike plate. Check that the weatherstripping is seated in its channel. If the door still binds or the lock won’t throw, that’s where DIY stops being smart. A full CGI door slab weighs somewhere north of 180 pounds for an impact-rated unit, and a door that heavy can break a hand or pin a foot faster than you can react. The frame on an impact door is structural, and shimming it wrong means the door will never seal or lock properly.

We also see the same expensive mistake on Houston jobs where a handyman replaced a slab without knowing CGI’s hinge prep system. The new door went in, looked fine for a month, then started binding because the hinges were mortised a quarter inch off. The fix cost more than the original install. Call us at (325) 326-4211 before you order anything, and we’ll tell you straight whether the job is worth doing and what it should cost.
