CGI Impact Garage Doors Nationwide

CGI Impact Garage Doors: The Pasadena Owner’s Guide

We stock and install CGI-compatible impact garage doors for homes throughout Pasadena, with most complete replacements running between $2,800 and $6,400 depending on size, panel design, and whether the existing track and hardware can be reused. We carry OEM CGI panels and hardware on our truck for the most common models, and we can typically complete a same-week installation once we confirm your door’s specs. Pasadena homeowners usually discover they need us after a storm season when a panel has dented, the bottom seal has torn away from a flood of Santa Ana debris, or the torsion spring has finally given out after years of daily cycles.

What surprises most owners is that an impact door can look fine from the street while failing quietly at the seal or spring level. A CGI door that still closes may no longer be protecting the garage the way it was rated to. Keith Yamada has walked enough Pasadena driveways to know the difference between a door that needs a tune-up and one that needs real parts, and we would rather tell you honestly which one you have than sell you a replacement you do not need.

Which CGI Models This Applies To

CGI impact garage doors fall into a few families, and the parts are not all interchangeable. The two most common lines we see in Pasadena are the CGI Sentinel series and the older CGI Estate series, plus the commercial-grade 3100 line on larger or custom garages. Each series uses slightly different panel thicknesses, track gauges, and spring specifications, so a part ordered from a generic catalog often arrives wrong.

The reliable way to identify your door is the white CGI label on the inside edge of the top panel, near the hinge. It lists the series, the wind-load rating, and a production date. Take a photo of that label with your phone before you call any supplier. If the label has faded or been painted over, we measure the panel thickness and the track width. A Sentinel panel is typically 2 inches thick with a foam core, while some Estate panels run thinner and use a different hinge spacing. That difference sounds small, but it means a hinge that bolts to one will not sit flush on the other.

For most Pasadena repair work, OEM CGI parts are the safer choice because the panel profile and finish match what is already on the house. Aftermarket hardware exists and can save money on items like rollers and cables, but we only use aftermarket parts where the spec truly matches. On anything structural, like hinges or panels, we order CGI.

Signs Your CGI Impact Garage Doors Is Failing

• The door shudders or jerks when opening. This usually points to a worn torsion spring or a cable that has started to fray inside the drum. Even one broken strand in a cable is enough to unbalance the door, and the problem compounds quickly once the remaining strands carry the full load.
• You can see daylight under the closed door. A sagging bottom seal or a panel that no longer meets the concrete is the first thing Keith looks for on a service call. In Pasadena, a broken seal is how Santa Ana wind-blown dust and the occasional heavy rain find their way into the garage.
• The door is louder than it used to be. Metallic grinding from the rollers or a rhythmic thump at one panel seam often means a hinge pin has worn oval, or a bearing in the track is failing. CGI doors are not silent, but they should not sound strained.
• One panel is dented or shows a stress crease. On an impact door, damage that looks cosmetic may have compromised the panel’s structural rating. If the door took a direct hit from a branch or a flying object during a storm, the panel has done the job it was built for, but it needs replacement to restore the original rating.
• The door reverses on its own or struggles partway up. This is rarely a sensor problem on a CGI door; it is more often a track that has shifted, a spring that has lost tension, or a panel that has swollen after water intrusion. Any of these means a repair, not just an adjustment.

Replacement Cost & What’s Included

In Pasadena, a full CGI impact garage door replacement with installation typically runs between $2,800 and $6,400. A single replacement panel, when we can match the existing series and finish, usually lands between $800 and $1,200 installed. A pair of torsion springs on a CGI door runs $320 to $480 including labor, and a new bottom seal assembly is $180 to $260.

What drives the price is the panel design, the door width (double doors cost more than singles), and whether your existing track is straight enough to reuse. Some Pasadena garages with older wood framing need the track remounted on new blocking before the door will balance correctly, and that adds a little labor. We write every price down before touching anything, so the number you approve is the number on the invoice.

Every part and panel we install is covered by our 365-Day Done Right Promise. If something is not right, we make it right, no debate and no countdown. That promise extends to the original job, and we come back if a hinge, seal, or spring we installed does not hold up the way it should.

DIY or Call Us?

There are two parts of a CGI door we will tell you to leave alone: the torsion springs and the lift cables. Both live under tension that can maim a person, and the springs in particular hold enough stored energy to break bone. A trained professional releases that tension in a specific sequence with the right winding bars. We have never once seen a homeowner attempt a torsion spring swap and decide it was worth the savings.

What you can safely do is inspect. Run the door by hand once with the opener disengaged and feel for resistance. Look at the cables for fraying. Check the bottom seal. Wipe the track clean. If any of that reveals an issue, call us at (626) 628-2308 and describe what you see. We will help you decide if it is a repair visit or just something to keep an eye on, and the estimate is free either way.
