CGI Door Installation Nationwide

CGI Door Installation: The Los Angeles Owner’s Guide

CGI door installation in Los Angeles typically runs $850 to $2,400 installed, depending on the door series and what failed. We stock CGI-compatible hardware and replacement components on our trucks for most of the product lines homeowners in LA actually have, and we can usually have a new door hung or an existing one rebuilt within one to two business days of your call.

Most people figure out something’s wrong the hard way. A door that used to glide suddenly sticks. The lock bolt doesn’t line up with the strike plate anymore. Or after a Santa Ana wind event, there’s daylight showing at the threshold. One small part fails, and it cascades into a door that doesn’t seal, doesn’t lock, or doesn’t feel safe anymore. By the time you’re reading this, you’ve probably already spent an evening trying to adjust it yourself.

Which CGI Models This Applies To

We work on CGI’s residential and light commercial door lines sold widely across Southern California, including the Estate Collection, the Classic series, and their impact-rated hinged door systems. The part that fails tends to vary by series. Estate Collection doors carry heavier panels and use commercial-grade hinges that rarely go bad, but the sweeps and threshold gaskets harden in LA sun within five to seven years. Classic series doors use standard residential hardware that’s easier to source but wears faster, especially the adjustable hinges and the latch cartridge.

Identifying your door is straightforward. Look for the CGI label on the hinge edge of the door slab, usually a white or silver sticker with the series name and a serial number. If that sticker is gone, measure the slab thickness. Most CGI entry doors are 1-3/4 inches thick, which is important because a lot of replacement parts sold online are spec’d for 1-3/8 inch interior doors. That mismatch is the number one reason a DIYer ends up with hinges or a latch that bind. The serial number also tells us which glass package and frame profile your door shipped with, which matters for replacement thresholds and weatherstripping. CGI uses proprietary threshold profiles on several series, and a generic big-box threshold won’t seat correctly. When an OEM part makes sense, we order it. When a quality aftermarket equivalent will perform as well or better, we tell you that upfront and show you both prices. Westlight Windows Los Angeles is an independent installer and service provider, not affiliated with CGI, so our recommendation is based on what works, not what we’re obligated to sell.

Signs Your CGI Door Installation Is Failing

• The door scrapes or drags on the threshold. This usually means the hinge screws have loosened or the top hinge has pulled back from the jamb. You’ll notice it’s worse in late afternoon, because the west-facing side of a house in Los Angeles expands measurably in direct sun. Once the slab drags, the sweep on the bottom wears through in a matter of weeks.
• You can see light around the edges, or the door rattles in wind. The weatherstripping has compressed or torn, and in impact-rated CGI models, that seal is also doing part of the storm protection job. Once the seal is gone, the door no longer sits solidly in the frame, and every gust of wind works the hinges harder.
• The lock latch misses the strike plate, or you have to lift the handle to get it to catch. The slab has settled or shifted in the opening. That’s not a lock problem, it’s an installation alignment problem. Forcing it by tightening the strike plate screws buys you a week or two, but the underlying sag keeps getting worse.
• The door binds at the top corner on the latch side. The header has settled, or the original installer shimmed the frame wrong. In older Los Angeles homes built on expansive soil, a quarter inch of movement at the foundation can translate to a door that won’t close at all during certain seasons.
• You can hear freeway or street noise at the edges. Sound gets through wherever air gets through. A door that was once quiet but now lets in the 405 hum or the Westwood night traffic sounds has lost its seal. On an impact-rated CGI, that same gap is where wind-driven rain works its way in during winter storms.

Replacement Cost & What’s Included

In Los Angeles, a full CGI door installation for a standard single entry usually falls between $850 and $1,600 when the existing frame is sound and we’re swapping the slab, hinges, hardware, and seal. If the frame has shifted and needs re-shimming, squaring, or partial rebuild, expect $1,400 to $2,400 depending on how much jamb work is involved. Full frame-and-slab replacement on a larger impact-rated double door starts around $2,200 and goes up from there.

What drives the cost is frame condition, not the door itself. A door slab that’s still square can be rehung in a few hours. A frame that’s been getting wet at the bottom, soft at the hinge screws, or racked out of square adds labor and materials. Every job gets a written price before we touch anything, and the number on that sheet is the number you pay. We don’t find surprises and revise the invoice after the fact. The labor is covered by our workmanship guarantee, and if something we installed fails within the first year, we come back and make it right at no charge under the 365-Day Done Right Promise.

DIY or Call Us?

You can safely diagnose a lot. Check whether the gap between the slab and jamb is even all the way around. Lift the door by the handle and feel for vertical play in the hinges. Look for cracked or compressed weatherstripping at the bottom and latch side. None of that requires tools, and it gives you real information before you call anyone.

The DIY line ends at hinge adjustment on a 1-3/4 inch impact-rated door. These slabs are heavy, often 150 pounds or more, and if a hinge pulls off while you’re trying to rehang one by yourself, the result is a broken door, a damaged floor, or a crushed foot. We regularly see CGI doors in neighborhoods like Palms and Mar Vista that were “fixed” with longer screws into stripped holes, which is a temporary patch that fails worse later. If your door is sagging, dragging, or won’t latch, call us at (213) 810-3461 and let a technician who hangs these doors weekly handle the real fix. The estimate is free.
