CGI Construction in Castroville, CA | Iron Beam Contractors
We provide independent CGI window and door service across Castroville, CA. We’re not authorized by the manufacturer, so our estimates and recommendations are based solely on what the structure and the homeowner actually need. The one thing that makes our CGI work different here is the fog-belt moisture: we spec flashing and drainage planes that most inland installers never think about. Call (833) 756-5936 for a free estimate.
Why Castroville Residents Choose Us for CGI Service
Our crews have installed and repaired CGI windows and doors across Castroville’s fog-belt housing stock, from older stucco bungalows in the flat town core to ranch outbuildings on the agricultural edges. We know how CGI Sentinel Series vinyl and Series 3000 aluminum units behave when they spend ten months a year in damp coastal air. Nolan Driscoll built Iron Beam Contractors on a straightforward principle: tell the homeowner exactly what’s in the wall before you open it, not after. When we quote a CGI repair or replacement in Castroville, you get real numbers, OEM-compatible parts where it makes sense, and a schedule that works around your life and the weather. One contractor, every phase, no vague talk.

Common CGI Construction Problems We Solve in Castroville
- Fogged or failed insulated glass on north-facing units. Castroville’s near-constant marine layer keeps north-facing stucco and shaded siding damp for much of the year. That moisture load translates directly into condensation between panes and eventual seal failure on CGI insulated glass, especially on north walls. We replace failed IGUs and check the frame for hidden water damage while we’re in there.
- Dry rot and mildew in CGI frames where drainage weeps are blocked. Damp, mild winters don’t freeze much, but they do keep wood and vinyl frames chronically wet. When weeps are clogged or missing, water has nowhere to go. We repair or replace affected frames, then correct the drainage path.
- Corroded hardware and seized operators on aluminum windows. Coastal salt air and persistent fog accelerate corrosion on CGI aluminum window hardware and fasteners. Sticking or seized operators are usually a hardware issue, not a structural one. We replace with OEM parts when available, or quality aftermarket hardware when OEM is discontinued.
- Improperly flashed CGI window openings. If the original installer treated Castroville like a dry inland jobsite, water gets behind the stucco and sits there. We’ve found hidden dry rot in wall framing more times than we can count. We pull the window, repair the framing, and install enhanced flashing and drainage planes.
- Fogged CGI sliding glass doors and patio doors. The same marine-layer condensation that fogs windows hits large glass doors harder, especially where afternoon sun finally breaks through and drives moisture into the frame. We diagnose whether it’s a seal issue or a frame issue before recommending repair or replacement.
CGI Service in Castroville: What Local Conditions Mean for Your Equipment
Castroville sits on the Monterey Bay coastal plain next to the Salinas Valley’s Salad Bowl, and the persistent marine layer means north-facing stucco and shaded siding in the town core are prone to chronic damp staining and dry rot. That’s not a line from a brochure; it’s what we see on CGI window openings every month. Standard inland installation practice puts a window in, caulks it, and walks away. That works fine in Salinas or CGI in Prunedale where things dry out. It does not work in Castroville, where the fog keeps wall cavities damp for weeks at a time. We spec enhanced weather-resistant flashing, proper drainage planes, and moisture-resistant trim on every CGI installation here. The same goes for roof repair around dormers and eaves: fog-driven moisture finds every gap. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
CGI Models & Products We Service in Castroville
We service the full residential CGI lineup: Sentinel Series vinyl windows, Series 3000 aluminum windows, and CGI sliding glass doors and patio doors. Our parts approach is simple: we source OEM CGI parts when they’re available for exact fit and finish, and we use quality aftermarket seals, glass, and hardware when OEM is discontinued or priced unreasonably. We stock common seal profiles, operators, and hardware for fast turnaround on Castroville jobs. For deeper equipment insights, see our CGI sales & service overview. We recommend repair over replacement when the frame and structure are sound; full replacement when multiple panes have failed or rot has compromised the frame.

FAQs – CGI Construction in Castroville
Fogging between panes means the insulated glass seal has failed. In Castroville, this happens most on north-facing walls because the marine layer keeps those surfaces damp and cool for most of the year, which stresses the seal until it fails. It’s not a cleaning issue; it’s a glass unit replacement. Call (833) 756-5936 and we’ll confirm the diagnosis.
Yes. We pull the window, remove the rotted framing, treat and replace the affected lumber, then reinstall with enhanced flashing and drainage planes so the problem doesn’t come back. The fix has to address the moisture path, not just the rot.
Not for windborne debris protection the way coastal Florida or the Gulf needs them. Castroville’s bigger threat is chronic moisture, not hurricane force winds. Impact windows do add structural rigidity and security, but most homeowners here get more practical value from properly flashed standard CGI units and good moisture management. We’ll be straight with you about whether impact windows are worth it for your specific exposure.
The fog keeps walls damp for weeks at a time, so caulking alone won’t keep water out of the rough opening. We spec enhanced weather-resistant flashing and drainage planes behind the stucco, plus moisture-resistant trim. If the original installation skipped that step, you’ll see the result as dry rot around the frame.
A single CGI window replacement typically falls between $4,500 and $15,000 depending on size, frame condition, and whether we’re repairing dry rot behind it. Impact-rated units run higher, in the $8,000 – $25,000 range. Estimates are free and fixed once quoted. Call (833) 756-5936 for a written line-item quote.
