ECO Window Systems Construction in Fountain Valley, CA | Daly City Construction
We provide ECO Window Systems service in Costa Mesa and across Fountain Valley, installing windows and doors and retrofitting new units into original 1960s and 1970s tract-home rough openings, not dropping windows into fresh framing. That changes how we flash, shim, and seal every opening, and it’s why our crews spend more time on the stucco cutback and sill detail than the window itself. If you’re in the 92708 or 92728 ZIP code and your ECO sliders are dragging or fogged, call (866) 505-5254 and we’ll put eyes on them.

Daly City Construction is an independent construction contractor that installs, repairs, and retrofits ECO Window Systems products. We’re not an authorized dealer and we don’t sell from a showroom. What we do is open up aging stucco walls in Fountain Valley and nearby, including ECO Window Systems repair in Westminster, and get the retrofit right, because that’s where these windows live.
Why Fountain Valley Residents Choose Us for ECO Window Systems Service
We work on ECO windows the way a framing crew works on a house, not the way a parts counter works on a warranty claim. When you’re dealing with a 1968 rancher off Brookhurst, the window isn’t the whole story. The rough opening behind it, the flashing under the stucco, the settle in the top plate, the way the original framer shimmed the sill in 1971, that’s the story.
Noel Cabrera, our owner, grew up in Daly City’s Westlake district, where he spent summers watching his uncle re-frame a garage and learned early what happens when someone skips the structural basics. He trained in construction technology at City College of San Francisco and has spent years swinging a hammer on residential work across San Mateo and San Francisco counties. That background matters here because Fountain Valley’s tract homes ask the same questions of every window opening: is it still square, is it still flashed, and is what’s behind the stucco still safe to bury under new trim.
We carry OEM-grade ECO replacement sashes, gaskets, rollers, and hardware for common retrofit units. If your frame is sound, we repair. If the rough opening has moved, we reframe before we install. One contractor for the wall and the window means no finger-pointing when the next Santa Ana blows through.

Common ECO Window Systems Construction Problems We Solve in Fountain Valley
Here’s what we actually see on ECO units in Fountain Valley, week after week:
- Santa Ana grit packing slider tracks. The original ECO single-sliders and horizontal sliders on 1960s and 70s tract homes have vinyl glazing gaskets and perimeter seals that harden over 30 to 50 years. Once those seals fail, wind-driven dust from a Santa Ana event loads up the tracks and weep holes until the sash drags or locks up entirely. We replace the gaskets, clean and re-screen the weep system, and re-lubricate the rollers. If the frame’s racked, we deal with that too.
- Fogged dual-pane units on south and west walls. Fountain Valley gets real sun load, and the desiccant inside older ECO dual-pane sealed units eventually saturates. Once the edge seal fails, the glass fogs. It’s not a cosmetic issue, the thermal performance is gone. We can often replace just the insulating glass unit when the original frame is still solid, which saves you half the cost of a full window replacement.
- Racked frames and sashes that won’t latch. Houses off Magnolia and Brookhurst have been settling for five decades. Original rough openings go out of square, and an ECO frame that was installed square now carries the twist. The sash won’t close fully, the lock misses, and air moves through the gap. We re-shim and re-square the frame where possible. Where the rough opening has moved too far, we reframe.
- Rot at the sill plate under original 1970s flashing. Many original tract openings were never detailed with modern flashing. Water gets behind the stucco, sits on the sill, and rots the wood. By the time a homeowner notices staining inside, the plate is gone. We cut back the stucco, replace the rotted framing, and re-flash the opening properly before the new unit goes in.
- Undersized or corroded fasteners failing at the perimeter. Original 1970s installs often used fasteners that were barely adequate on day one. After decades of coastal air and occasional moisture, they’ve given up. The window stays in place, but the seal at the flange is broken. We install new fasteners sized for the actual load and re-seal the entire perimeter.
ECO Window Systems Service in Fountain Valley: What Local Conditions Mean for Your Equipment
Fountain Valley is built out, nearly every lot was platted and every house was up by the late 1970s. There’s no greenfield land here. So when a homeowner wants a bigger window, a slider where a pair of single-hungs used to be, or glass across a rear addition, the work always means cutting into original framing. It also means the wall cavity behind that stucco off Brookhurst or Magnolia is likely hiding 1970s aluminum branch wiring and original galvanized or ABS plumbing. Enlarge an opening enough, and you trigger a code requirement to bring what’s inside the wall up to current standard. That’s not a surprise we spring on you after the saw comes out, it’s what we flag during the estimate walkthrough. It’s also why we carry full Fountain Valley General Contractor capability, not just a window truck, so the framing, the electrical, the plumbing, and the new ECO unit all get handled by one crew under one plan.
On a 1968 ranch off Brookhurst, a homeowner wanted the rear wall of ECO sliders replaced. Once we cut back the original stucco, we found two rough openings had racked and the sill flashing had never been detailed properly, water had been wicking into the plate for years. We reframed and re-flashed those two openings, re-shimmed the rest, set new dual-pane ECO units with fresh gaskets and weep-hole screens, and patched the stucco so the tracks stopped loading up with grit every Santa Ana event. The homeowner told us later that was the first windy season his sliders didn’t sound like a sandbox.
ECO Window Systems Models & Products We Service in Fountain Valley
We handle the ECO Window Systems units most common on Fountain Valley tract houses: vinyl single-hung and single-slider replacement windows, vinyl horizontal sliders and fixed picture windows for patio and rear-yard walls, and ECO sliding glass patio doors on ranch and two-story homes. We also work with dual-pane retrofit units where the original grid pattern matches the tract fenestration, because in Fountain Valley, keeping the street-facing elevation consistent matters. When we repair, we use OEM-grade ECO sashes, gaskets, rollers, and hardware where the frame is sound. We stock common parts for the retrofit lines we see most, which keeps turnaround shorter than special-ordering from a distributor. For full window or door replacements, our ECO Window Systems sales & service team walks you through what’s available and what actually fits your openings.

FAQs – ECO Window Systems Construction in Fountain Valley
Yes, Fountain Valley requires permits for window replacement when the opening changes size or structural elements are touched, and on a 1970s tract home, that’s most retrofit work. We pull all required permits and handle the inspections. It matters because your original openings may not meet current egress or energy code, and if we’re enlarging an opening, the wall cavity may require electrical or plumbing upgrades to pass. Patching around the issue isn’t legal and it isn’t smart. Call (866) 505-5254 and we’ll tell you exactly what your project triggers.
Usually what’s failing is the perimeter gasket and seal, not the window itself. Once those hardened vinyl seals stop closing off the frame from the outside, Santa Ana wind drives dust and grit into the tracks and weeps, and the sash starts dragging. The fix is fresh OEM-grade gaskets, clean weep holes with proper screens, and re-lubricated rollers. If the frame has racked from decades of settle, that’s a separate issue we address by re-shimming or reframing. Call (866) 505-5254 and we’ll diagnose it on site.
Sometimes. It depends on the wall. If we’re widening an opening by a foot on a non-load-bearing gable wall with no plumbing or wiring in the cavity, it’s straightforward. If we’re cutting into a shear wall or a wall carrying roof load, we engineer the header and add the required strapping. And on Brookhurst and Magnolia tract homes, we may find aluminum branch wiring or galvanized plumbing behind the stucco that must come up to code before we close the wall. We’ll scope this during the estimate, not after demolition. Call (866) 505-5254.
If the frame and rough opening are sound, we can often replace just the insulating glass unit at a fraction of the cost of a full window. The fogging means the seal failed and the desiccant is saturated, but the frame may have decades left. If the frame is racked, corroded, or the sills are rotted, replacing the glass alone just puts new glass into a failing structure. We evaluate each opening and tell you straight which is the honest call. Call (866) 505-5254 for a free assessment.
Most Fountain Valley homeowners adding a multigenerational suite on the rear of the house want the new windows to match the existing ECO units on the street-facing elevation so the house reads as one building. On the addition itself, we often recommend dual-pane low-E with a matching grid pattern to keep fenestration consistent. Code will set the minimum egress and energy requirements. We’ll bring samples from our ECO Window Systems service in Huntington Beach and ECO Window Systems service in Crestline colleagues so you can see exactly what matches.
