CGI Windows & Doors: The Houston Owner’s Guide
Elmstead Remodeling Houston stocks and installs CGI-compatible window and door parts across the Houston metro, with most replacement jobs running $400 to $1,800 for a single sash, hinge, roller assembly, or locking mechanism depending on the CGI series and what failed. We carry OEM CGI components and quality aftermarket equivalents on our trucks for the most common failures, so a call to (254) 272-5240 can often get a matching part on the schedule that same week. The way most Houston owners discover a part has failed is simple: a door stops closing flush against the frame, a crank handle spins without moving the sash, or a window that once sealed tight against an August afternoon has started to let in a warm draft and street noise.
CGI is built around impact-rated products, originally designed for coastal Florida codes, and Houston has come to adopt those standards for a reason. The aluminum frames, heavy laminated glass, and tight thermal breaks do not fail quietly, but when a component does go, it tends to be a predictable list: spring balances tired after years of 100-degree south-facing exposure, rollers on sliding doors ground down by Gulf Coast grit, weatherstripping compressed flat after a decade of thermal cycling, or hinge hardware that gave way because the door was never shimmed correctly during a previous install. This page covers what fails, what it costs in Houston to fix, and how we match the right part to your CGI model.
We are an independent service provider, not affiliated with CGI. What that means for you is straightforward: we tell you honestly if an OEM part is worth the wait or if a quality aftermarket equivalent will do the job just as well, for less, and we put that recommendation in writing before any work starts.
Key Takeaways
- CGI window and door part replacement in Houston typically runs $400 to $1,800 installed, depending on the series and component.
- We stock common CGI-compatible parts on our trucks: spring balances, roller assemblies, hinge sets, locking hardware, and weatherstripping cut to fit CGI aluminum profiles.
- CGI uses series-specific glass packages and hardware, so matching the part number from the label on the sash or frame is the first step.
- DIY is safe for inspection and simple weatherseal swaps, but spring balances and door hinge pins carry genuine injury risk.
- Every job gets a written price before work starts, drop cloths on the floor, and the 365-Day Done Right Promise.
Which CGI Models This Applies To
CGI manufactures impact-rated windows and doors in several series, each with different frame profiles and hardware. The most common lines we see in Houston homes are the Estate Series, the Estate Entrances, and the narrower-profile Contractor Series for production builds, along with legacy CGI aluminum single-hung and casement lines that date back before CGI expanded deeper into the Texas market. Impact-rated means the laminated glass and reinforced frame are test-certified to withstand windborne debris, and the hardware on these units is heavier than what you would find on a standard builder-grade window. That matters for replacement parts, because a generic roller or balance shoe from a big-box aisle rarely matches the weight and profile CGI units need.
How to identify your CGI window or door: every CGI unit carries a label, typically on the top or side rail of the sash, or on the edge of the door panel. The label includes the series name, a product code, and the manufactured date. If the label has faded or been painted over, the dimensions of the visible glass, the frame depth, and a close photo of the hardware get us most of the way to a positive match. One compatibility gotcha we see often in Houston: CGI locking hardware and rollers differ between the Estate and Contractor series, and they do not interchange cleanly. A Contractor Series roller will not ride properly in an Estate Series track, and the lock keepers are drilled for different screw patterns. For that reason, we always pull the old part during the free estimate and match it physically before we quote the replacement.

Signs Your CGI Windows & Doors Is Failing
- Sliding door drags or crunches when opened: The roller assemblies on Houston patios collect sand, cedar pollen, and construction grit, and once the bearings seize, the door starts dragging. A dull crunching sound is the roller housing grinding against the rail, and ignored long enough, it chews up the aluminum track.
- Crank handle turns but the window does not move smoothly: On casement windows, a spinning handle with sluggish sash movement almost always means the operator gear teeth have stripped or the hinge arms have worn. Houston humidity accelerates corrosion on the internal screw stubs, especially on units mounted under sprinkler heads.
- Single-hung or double-hung sash creeps down or is hard to lift: The spring balances that hold the sash weight have aged. South and west-facing Houston windows bake in direct sun, and a balance that fails at year ten or twelve is common, not defective, but it makes the window a real chore to operate.
- Visible daylight around the door or window edge when closed: This is weatherstripping that has compressed, torn, or pulled out of its kerf. You should not see any light through a closed CGI door; if you do, the seal has gone and your HVAC is paying for it.
- Lock no longer catches, or the door rattles when the wind picks up: Multi-point locks on CGI doors have keeper alignment that shifts with the house settling, and Houston clay soil moves more than most. The hardware is usually still good; the fix is realigning or shimming the keeper, or replacing the broken linkage in the edge channel.
Once any of these failures starts, the part rarely heals itself. Catching the failure early, before a dragging roller scores the track or a failed balance lets the sash drop hard enough to crack the corner weld, is the difference between a $400 part change and an $1,800 run to replace the sash.
Replacement Cost & What’s Included
CGI part replacement in Houston ranges from approximately $400 for a single weatherstripping and hardware tune-up to $1,800 for a full sash replacement with glass packaging. The biggest driver of price is what failed: roller and hinge replacements run $400 to $800 per unit, spring balance replacement runs $300 to $700 per sash, multi-point lock replacement runs $500 to $1,100 per door, and if the impact glass itself has a crack or stress fracture, the replacement glass pack can run $800 to $1,800 based on size and series. What determines whether we recommend OEM or aftermarket is the same thing every time: the failure mode and how much wear the rest of the unit has already absorbed. On a ten-year-old door, a $90 OEM roller is not always the wiser buy when a $45 aftermarket roller with sealed bearings will outlast the rest of the door’s service life. We will show you the options and our recommendation with prices next to each.
Every quote is in writing before work starts, with the part cost, labor, and any disposal separate so there is no mystery. Drop cloths go down in the room where we work, the work site is swept after, and you get a photo of the clean-up before the crew leaves. If the replacement part fails within a year, the 365-Day Done Right Promise means we make it right, no argument and no invoice.

Some of this you can safely do yourself. Checking the label for a series number, cleaning the track, and replacing a compression weatherstrip is reasonable homeowner work, and if the sash is heavy, team-lift it or leave it alone. But the moment you are dealing with spring balances under tension or a heavy CGI door panel on its rollers, the risk is real. Spring balances store energy, and a slipped grip can snap the spring through a finger or send the sash into the frame hard enough to crack the glass. Multi-point lock hardware sits inside a channel in the door edge, and forcing a linkage back into place without understanding the throw sequence bends the rod and costs you more than the service call. If the part involves tension, a ladder, or a pane of impact glass that weighs more than you do, call us at (254) 272-5240. The estimate is free, and the answer about whether you can handle it yourself is free too.
FAQs
In Houston’s heat and humidity, you can expect a 10 to 15 year service life for most CGI hardware before a part begins to show wear: spring balances on unshaded south and west-facing windows often give out at year ten, rollers around year twelve depending on track grit, and multi-point locks usually hold up to fifteen or more if the house has not settled significantly. Regular track cleaning and keeping weep holes clear extends every part’s life.
Hardware failures are almost always replacement-by-design: stripped gears, seized bearings, and fatigued springs do not rebuild well, and a “repaired” roller or balance typically fails again within months. The exception is a misaligned multi-point lock or a dragging door that just needs shimming and adjustment, which is a service call, not a part change. Call (254) 272-5240 if you are not sure which camp you are in; we will tell you over the phone what to photograph so we can give you an honest read before we even schedule the visit.
Most single-part CGI replacements, like one roller assembly, one set of spring balances, or one multi-point lock, are done in two to four hours. A full sash or glass pack swap can take half a day because the glass is heavy and the glazing has to seat properly, and we are not going to rush that. We will give you a written time range before we start, and we keep the work area covered the whole time.
We stock the most common CGI-compatible parts on the truck: spring balance sets, roller assemblies, hinge sets, keepers, and weatherstripping profiles for Estate and Contractor series. Less common parts, like full glass packs or proprietary multi-point lock bodies, we order direct from CGI or a certified aftermarket supplier, which usually means one to two weeks in the Houston area. When we come out for the free estimate, we match the old part physically, and if we do not have it on the truck, you will know exactly how long the order takes before you decide anything.
