CWS Construction in Santa Ana, CA | Daly City Construction
We service CWS windows and doors across Santa Ana, CA, with crews that work on the city’s older stucco bungalows and Spanish-style homes every week. What sets our work apart here is simple: we know how CWS units behave in pre-1960s housing stock, and we diagnose problems the way a contractor who actually works in Santa Ana would, not the way a manufacturer’s brochure would. We’re an independent contractor, not a CWS dealer or authorized warranty shop. Call (866) 505-5254 for service that’s built on hands-on local retrofit work, not a badge.

Why Santa Ana Residents Choose Us for CWS Service
Noel Cabrera, our owner, grew up in Daly City’s Westlake district, where the fog and salt air taught him early that a window is only as good as the flashing behind it. That lesson transfers directly to Santa Ana’s older homes, where the original CWS aluminum units are often still in place decades after they should have been rebuilt. Our crews pull and reset these windows the right way: off comes the trim, out comes the old weathered putty and worn pile weatherstripping, and in goes spec-matched replacement rollers, balances, and sashes when the frame is still worth saving. We don’t sell replacements just because it’s easier for us to order a new unit. If the glazing is fogged and the frame is racked, we’ll tell you straight that replacing beats rebuilding, and we’ll walk you through why. That’s the kind of CWS sales & service knowledge that comes from doing, not reading.

Common CWS Construction Problems We Solve in Santa Ana
- Original CWS aluminum single-hungs that rattle and leak air. These are everywhere in Santa Ana’s 1950s and 60s tract homes. The pile weatherstripping is worn down to nothing and the rollers are so corroded the sash grinds instead of slides. We replace the weatherstripping and rebuild the roller assemblies so the window actually shuts tight again.
- Fogged insulated glass on CWS vinyl double-hungs. Santa Ana’s hot inland summers cook the edge seals on these units. Once the seal fails, moisture gets between the panes and the glass fogs permanently. We source replacement insulated units matched to the original frame specs, so you keep the window and lose the fog.
- Water intrusion at CWS window and patio-door perimeters. Older Santa Ana homes with original stucco and missing flashing let wind-driven rain in around the unit edges. We correct the rough opening, add pan flashing, and reseal the perimeter so water stops finding its way inside.
- Sliding-door track corrosion and roller failure on CWS patio doors. The Santa Ana winds push dust and grit into alley-facing openings. That grit grinds into the tracks and rollers until the door binds or drags. We clean, rebuild, and reset the door so it glides the way it did when it was new.
- Racked frames from unpermitted past additions. When an old addition shifted, the window opening often went with it. A CWS unit in a racked opening will never operate or seal correctly until the rough opening is corrected. We fix the rough opening first, then set the window square and level.
CWS Service in Santa Ana: What Local Conditions Mean for Your Equipment
Here’s what makes Santa Ana different from the newer cities around it: permits and inspections run through the City of Santa Ana’s own building department, not the county. And because so many homes in the 92701 through 92707 ZIP codes carry unpermitted past additions, our window and door replacements often have to bring the existing opening into compliance before the new unit can be signed off. The city inspector checks the rough opening, the flashing, the egress, and the structural adequacy of the lintel before the window gets final approval. This means a simple CWS window swap on a 1950s bungalow in the historic core can involve rebuilding the opening first, then scheduling the inspection, then setting the unit. If you’re in one of the newer master-planned developments ringing Santa Ana, you’d almost never encounter this. Here, it’s routine. Our crews know the City of Santa Ana inspectors, know what they flag, and know how to stage the work so you don’t get stuck with a pile of stucco and an unanswered inspection request. We keep the sequence moving because we’ve done it hundreds of times.
Noel tells homeowners the same thing whether he’s on a job off Main Street or on one near Segerstrom: “Tell me what the house needs, not what you think it needs – then we’ll figure out the right fix.” That’s how we approach every CWS window we touch in this city.
CWS Models & Products We Service in Santa Ana
We service the CWS lines most common in Santa Ana’s housing stock. The original aluminum single-hung and sliding windows found in mid-century tract homes make up a big share of our work. We also service CWS vinyl double-hung replacement windows, which many homeowners installed in bungalow and Craftsman retrofits during the 1990s and 2000s. CWS sliding glass patio doors on older Spanish and Mediterranean stucco homes are another regular service item, along with CWS steel and aluminum entry door systems on historic-core properties. For parts, we source OEM or spec-matched CWS replacement sashes, rollers, balances, and weatherstripping when the frame and glazing are still sound. We keep a working inventory of the most common CWS roller sizes, balances, and weatherstripping profiles in our Santa Ana service vehicles so we’re not waiting on a parts shipment every time a homeowner calls.

AfterCWS Service Pricing in Santa Ana
Here’s what CWS window and door service typically runs in Santa Ana. Window replacement on an older Santa Ana home is usually between $4,500 and $15,000, depending on how many windows are replaced, whether the rough openings need structural work first, and whether we’re bringing the openings into City of Santa Ana code compliance. Impact window installation runs $8,000 to $25,000 because of the heavier frame construction, impact-rated glass, and the additional flashing and anchoring required. Our free estimate walks you through what you actually need. Call (866) 505-5254 for an exact quote; estimates are free, and we’ll tell you plainly if repair beats replacement for your specific units.

FAQs – CWS Construction in Santa Ana
Yes. The City of Santa Ana building department requires permits and inspections for window replacements that alter the rough opening, and that’s the case for most pre-1960s homes in Santa Ana where we’re correcting old flashing and stucco at the same time. We pull the permit, schedule the inspection, and walk the work through completion. Call (866) 505-5254 if you’re not sure whether your specific project needs one; we’ll tell you straight.
If the frame and glazing are sound, we repair it. Worn pile weatherstripping and corroded rollers are the most common culprits on these 1950s and 60s CWS units, and both are replaceable with spec-matched parts that bring the window back to tight and quiet. If the frame is racked or the glazing has failed, replacement is usually the honest answer. We’ll tell you which way to go after one look.
The edge seal on the insulated glass unit has failed. Santa Ana’s hot inland summers bake these seals until the desiccant inside the unit saturates and moisture gets trapped between the panes. Once fogged, the glass unit needs replacement, not repair. We source replacement insulated units matched to your original CWS frame specs. Call (866) 505-5254 for a free estimate.
We can. On a 1950s stucco bungalow near downtown Santa Ana, our crew pulled a set of fogged, drafty CWS aluminum single-hungs and found the rough openings had no flashing and cracked original stucco at the sill. We rebuilt and flashed the openings, reset the units with proper pan flashing, and patched the Spanish stucco so the elevation matched, then walked the work through the City of Santa Ana inspection. The homeowner got sealed, quiet windows that finally kept out the Santa Ana wind dust and winter rain. We match stucco texture and color, frame and trim style, and window proportions to the era of your home.
We do. Sticking tracks and leaking thresholds on CWS patio doors in Santa Ana are usually the result of dust and grit from the seasonal winds working their way into the track assembly, or a rough opening that has shifted over time. We rebuild the roller assemblies, clean and re-align the track, correct the flashing, and reseal the perimeter. If the glass is fogged or the door panel is racked beyond repair, we’ll tell you that replacement is the better path. Call (866) 505-5254 to schedule a look.
