ES Windows Construction in Cypress, CA | Milpitas Construction
We provide independent ES Windows replacement and retrofit work across our Cypress service area, and the one thing that makes our service different here is simple: we know what Cypress City Hall wants to see before the plan check reviewer circles it. We’re not manufacturer-affiliated, we’re not an authorized dealer, and we’re not going to pretend otherwise. What we are is a full-scope general contractor that has installed and serviced ES Windows lines in enough 1960s and 70s Cypress tract homes to know exactly how these windows fail here and what it takes to bring them up to current Title 24 code. Call (877) 752-4194 for a free estimate, and we’ll tell you straight whether repair or replacement makes sense for your house.
Why Cypress Residents Choose Us for ES Windows Service
Most window companies in Orange County sell you whatever brand they carry. We take a different approach. Ken Stafford, owner at Milpitas Construction, built his reputation on doing work that holds up, and that starts with knowing the product you’re working on. Our crew has pulled apart enough ES Windows 8000 Series aluminum frames and 5500 Series vinyl double-hungs across Cypress to know which failures are worth repairing and which ones are just buying you a year before the next problem shows up.
We spec materials by name, so you know exactly what’s going into your home. When an OEM latch or roller is still available, we get it. When it’s been discontinued for a decade, we reach for an aftermarket equivalent that meets the original spec, not whatever’s cheap at the supply house. And because we’re local to Cypress and Orange County, we’re not driving in from Riverside and guessing at your city’s permitting quirks.
If you’re looking for ES Windows sales & service, know this: we service what we install, and we’ll tell you honestly when a repair makes no financial sense on a 25-year-old frame.

Common ES Windows Construction Problems We Solve in Cypress
Here’s what we see most often across Cypress, and why it happens here specifically:
- Fogged dual-pane glass on 8000 Series aluminum single-hungs. Failed glazing seals are the number one call we get in Cypress’s original tract neighborhoods. These windows are often 20-plus years old, and once the seal goes, you lose the insulating gas and the glass fogs permanently. In Cypress Village and the neighborhoods near Moody Street, we see this constantly.
- Corroded, pitted aluminum frames that bind the tracks. Cypress isn’t beachfront, but it’s coastal-influenced enough that salt air works its way inland. ES Windows aluminum frames from the 1980s pit and corrode, especially on the bottom tracks. During Santa Ana wind events, those rough tracks make opening and closing a fight.
- Warped vinyl on south- and west-facing windows. Cypress gets real, sustained UV. The ES Windows 5500 Series vinyl frames on south-facing walls, which are everywhere in these tract layouts, can warp and crack over time. When that happens, the sash stops sealing and you’re paying to air-condition the patio.
- Worn latches, rollers, and weatherstripping. Original ES Windows hardware from the 1970s and 80s is often discontinued. Worn hardware means drafts, security concerns, and windows that won’t stay locked. We either source the OEM part or install an aftermarket piece built to the same spec.
- Water intrusion around older ES Windows during Santa Ana-driven rain. When wind drives rain against a 40-year-old window with cracked exterior sealant and failing weatherstripping, the leak shows up on the drywall inside. In Cypress, where many homes still have original window openings cut for 1960s framing, this is a common call.
ES Windows Service in Cypress: What Local Conditions Mean for Your Equipment
Cypress is a largely built-out, master-planned Orange County suburb. There’s almost no vacant land left, which means nearly every job we do here is a remodel, addition, or window replacement squeezed onto an existing lot with tight setbacks and older tract-home framing. That changes how we approach ES Windows service in Buena Park and surrounding areas. We’re not doing new construction, we’re retrofitting windows into openings that were framed 50-plus years ago, often with non-standard dimensions that the original ES Windows models were cut to fit. That’s why we measure every opening ourselves rather than trusting the original window label. It’s also why our plan check submissions to Cypress City Hall include more detail than a neighboring city would typically ask for. For any Cypress homeowner within the 90630 ZIP, the practical takeaway is this: your window project is as much about the paperwork and the framing as it is about the glass itself.
And here’s the part generic window pages miss entirely. Cypress enforces Title 24 energy compliance more rigorously than some of the cities around us. That means when you replace ES Windows in Cypress, product selection matters. You can’t just slap any double-paned unit into the opening and call it done. The glazing, the U-factor, the solar heat gain coefficient, these all have to meet current California code, and the city checks. Build it right the first time, the Bay Area doesn’t give you a free pass on shortcuts, and neither does Cypress City Hall.
ES Windows Models & Products We Service in Cypress
We work on the four ES Windows lines most common in Orange County housing stock: the 8000 Series aluminum single-hung, the 5500 Series vinyl double-hung, the 3000 Series horizontal slider, and the 2000 Series awning, including ES Windows in Stanton and nearby cities. We carry a local stock of common OEM hardware, glazing seals, and weatherstripping for these lines so we’re not waiting on a freight shipment every time a Cypress homeowner needs a track rebuild. For discontinued parts, we have aftermarket suppliers we’ve vetted over years, and we’ll always tell you which one we’re using and why.

AfterES Windows Service Pricing in Cypress
Here’s what Cypress homeowners can expect for ES Windows-related work. Window replacement typically runs $4,500 to $15,000 depending on the number of openings, the model you’re replacing, and whether you’re moving to impact-rated glass. Impact window installation, which matters for Santa Ana fire-weather seasons out here, runs $8,000 to $25,000. What drives the cost is whether you’re repairing a track or replacing a full frame, the U-factor and SHGC required for Title 24, and the condition of the rough opening once we open it up. Our estimates are free, line-item, and written, so call (877) 752-4194.

FAQs – ES Windows Construction in Cypress
These are the questions Cypress homeowners ask us most, answered straight.
In most cases, yes, the glass alone can be replaced if the frame is still sound. We can install a new dual-pane insulated glass unit in an existing ES Windows frame, which costs far less than full replacement. The deciding factors are frame corrosion, whether the sash is square, and whether the seal failure is isolated or the frame is also failing. Call (877) 752-4194 and we’ll assess it in person.
Yes. Cypress requires permits for window replacement, and the units have to meet current Title 24 energy standards. We handle plan check drawings, product documentation, and the inspections that follow. If a contractor tells you Cypress doesn’t require permits for window replacement, call someone else.
Repair makes sense when the frame is structurally sound, the glass isn’t fogged, and the issue is a worn roller, latch, or weatherstripping. Replacement makes sense when you have failed seals, corroded frames, warped vinyl, or you’re fighting drafts every winter. We’ll walk you through the math on both options.
For a standard Cypress tract home of four to eight windows, most replacements take one to two days of installation after permits are issued. The permitting timeline depends on Cypress City Hall’s current plan check queue. We handle that coordination so you’re not waiting on the phone with the building department.
ES Windows as a manufacturer has gone through changes over the years. Some model lines are discontinued. When we can’t source the exact match, we’ll recommend a replacement product that mirrors the original profile as closely as possible, and we’ll show you samples before any work begins. Call (877) 752-4194 for a free estimate and we’ll sort out which options apply to your home.
