CGI Construction in Pasadena, CA | Elmstead Remodeling Pasadena
We’re Elmstead Remodeling Pasadena, and as a General Contractor in Pasadena we provide independent CGI service across the area – window repair, patio door work, glass replacement, and full installations. The thing that sets our CGI work apart here is that we deal with pre-1950 houses every week, so we know how a CGI window behaves in an opening that was framed before drywall existed. Call (626) 714-2992 for a free estimate.
Why Pasadena Residents Choose Us for CGI Service

Graham Stein, our owner, learned the trade at Los Angeles Trade-Technical College and spent nearly two decades swinging a hammer across the San Gabriel Valley before starting this crew. When a CGI window fails in a Pasadena house, we treat it like the structural opening it is – not just a glass unit to swap. We carry OEM CGI hardware like cam locks, keepers, and roller assemblies when they’re still available, and we keep aftermarket weatherstripping and Cardinal glass units on hand for the jobs where OEM parts have been discontinued. We show up with shoe covers for the hallway, drop cloths under the work area, and a written price in your hand before the first screw comes out.

Common CGI Construction Problems We Solve in Pasadena
These are the failures we see repeatedly in Pasadena homes, tied to the local climate and the age of the housing stock:
- Seal failure in west-facing sunroom sashes. Pasadena’s dry summers bake west-facing CGI vinyl sashes hard. In Craftsman sunrooms, they often develop perimeter seal failure within 8 to 10 years – fogging between the panes, hairline cracks at the glazing bead. We pull the sash, replace the insulated glass unit with a low-E Cardinal unit, and re-bed the glazing before resetting it.
- Worn corner keys after seismic retrofit work. The thermally-broken aluminum frames on CGI Estate Series units in Spanish Colonial homes often have corner keys that wear out after an earthquake retrofit stiffens the wall. The opening sash sags and won’t lock tightly. It’s a mechanical fix, not a glass fix, and we handle it in place.
- Patio door rollers that bind and pit from Santa Ana grit. Fine dust off the San Gabriels gets into CGI patio door tracks on raised-foundation bungalows near Bungalow Heaven. Rollers bind, pit, and the door jumps the track. We replace the roller assemblies, clean the track, and adjust the reveal so the door seats correctly.
- Leaking sills on 1990s pocket openings. Original CGI Estate 100 single-hung windows installed in 1990s remodels frequently sit in non-flashed pocket openings. During Pasadena’s cool, wet winters, water drives in at the sill and starts dry rot in the adjacent wood framing. We pull the window, flash the opening properly with flexible tape, and reset the unit.
- Sightline mismatches in historic districts. In Bungalow Heaven and other landmark districts, replacement windows have to match the original sightlines and exterior trim profiles. We’ve seen CGI units installed with the wrong casing and the wrong divided-light pattern get flagged at design review. We order the custom millwork and the correct grille pattern before the inspection, not after.
CGI Service in Pasadena: What Local Conditions Mean for Your Equipment
Here’s the thing most contractors won’t tell you: Pasadena’s Historic Preservation Commission requires any window replacement in a landmark district like Bungalow Heaven to match the original sightlines and exterior trim profiles. That means a standard CGI install with off-the-shelf casing won’t pass design review. Our CGI installs in those neighborhoods often involve custom-milled exterior casing and divided-light patterns that replicate the 1910s Craftsman look while using modern impact-rated glass. The window itself gets better – clearer glass, tighter seals, a real weatherstripping system – but the exterior reads as original. Graham has spent enough afternoons in those older Craftsman homes to know that a careful demo and a slower hand are the only way to work in an opening that’s been holding a window since the first World War. If you want to see how we approach window work across the broader area, our Pasadena service area page walks through it street by street.
CGI Models & Products We Service in Pasadena
We work on the full CGI lineup that’s landed in Pasadena homes over the past three decades: the CGI Estate Collection, CGI Simonton Reflections 5500, CGI Estate 100 Series, and CGI Estate 110 Series. For hardware, we source OEM CGI cam locks, keepers, and roller assemblies whenever they’re still available for your model. When OEM parts are discontinued or backordered for weeks, we use high-quality aftermarket weatherstripping and glass units from Cardinal or PPG – and we tell you exactly which we’re using and why before we start. If the frame is racked or the glass unit has failed in more than two sashes, we’ll usually recommend full window replacement instead of piecemeal repairs, because patching a racked frame just moves the failure down the road.

FAQs – CGI Construction in Pasadena
Yes, but only when the installation includes the anchoring and flashing details that Pasadena’s building department expects on pre-1950 homes. A retrofit stiffens the wall, and the window has to move with that stiffer structure. We check corner keys, the reveal around the sash, and the opening’s squareness before we install, because an out-of-square opening in a 1910s lath-and-plaster wall will bind any new window regardless of brand.
Yes, if the frame is square, rust-free, and the corner keys are intact. We pull the sash, order a new insulated glass unit from Cardinal or PPG to the exact dimensions, and set it back in. If the frame itself is racked or the glazing bead won’t seat cleanly, we’ll recommend replacing the whole unit rather than spending your budget on a repair that won’t hold.
Almost always, fine grit from Santa Ana winds has settled into the track and pitted the rollers. The doors sag, the wheels catch, and the panel hops the rail. We clean the track, replace the roller assemblies, and reset the panel height so it rides true. If you hear grinding when the door moves, stop using it until we look – a jumped panel can crack the glass. Call (626) 714-2992 and we’ll get it scheduled.
They can be, if you spec the right glass and the right frame. Modern CGI impact-rated units with tempered glass hold up better against ember exposure than single-pane originals, and a properly flashed opening with fiberglass mesh screening at any vent gaps makes a real difference. Homes in the higher elevations near Altadena benefit from the tighter seal, but the install has to be correct – gaps around the frame are where embers find a way in. We can walk your property and tell you honestly which windows need attention and which can stay.
In a landmark district like Bungalow Heaven, yes, you’ll need design review before any exterior-visible replacement. The commission checks sightlines, trim profiles, divided-light patterns, and sometimes mortar or casing color. In non-historic parts of Pasadena, window replacement with the same opening size usually doesn’t require a full building permit, but our crew pulls permits whenever the city requires them – and we handle the paperwork so you don’t have to chase it. Call (626) 714-2992 and we’ll check your address against the city’s requirements.
