ES Windows Construction in Lake Forest, CA | Moreno Valley Builders
We provide independent ES Windows service and replacement across Lake Forest, CA, with a focus on the original single-pane aluminum sliders still sitting in the stucco openings of tract homes built between the late 1960s and early 1990s. What makes our ES Windows work here different is simple: we know which units fail, why they fail in this specific climate, and whether a repair or a full-frame replacement actually makes sense on a Lake Forest home. Call (877) 752-3154 for a free estimate.
At Moreno Valley Builders, we’ve spent years pulling, re-glazing, and re-flashing ES Windows aluminum and vinyl units on the aging homes that define this city’s housing stock. We’re an ES Windows sales & service contractor, independent of the manufacturer. That independence means we can match the correct profile and glass package to your existing frames without being locked into a single replacement line. We serve the entire Lake Forest service area, from the older Saddleback Valley streets to the newer tracts, with the same material-savvy approach we bring to every trade we manage.
Why Lake Forest Residents Choose Us for ES Windows Service
ES Windows has been a fixture on California exterior openings since the 1960s, and the original units on Lake Forest’s late-1960s-to-early-1990s tract homes are now hitting the end of their service life all at once. We know these windows because we’ve removed enough of them to see exactly how they were flashed, how the stucco was applied around them, and what happens when the felt channels and weatherstrip finally give out on sliders that have survived forty-plus Southern California summers.
Noel Trevino, Owner and General Contractor at Moreno Valley Builders, grew up in Sunnymead Ranch and has spent nearly three decades building and renovating homes across the Inland Empire. He learned framing, concrete, and mechanical systems at Riverside City College, and he’s the contractor neighbors call when a previous job went sideways. “If the details aren’t right on paper, they won’t be right in the wall.” That’s the standard we bring to every ES Windows tear-out, re-glaze, and re-flash in Lake Forest.
We stock OEM-equivalent ES Windows profile, glass, and hardware locally, which means we can turn around most re-glazing and weatherstripping work quickly without waiting on a distributor in another county. For full-frame replacements, we quote line-item pricing and handle the HOA documentation, permits, and inspections as one accountable contractor.

Common ES Windows Construction Problems We Solve in Lake Forest
- Aluminum frame thermal bridging and condensation. The original single-pane ES Windows aluminum sliders on 1970s-80s Lake Forest tracts sweat heavily during inland temperature swings. That condensation corrodes the frame, stains the stucco sill, and eventually eats into the sealing surfaces. We see this on nearly every tear-out we do here.
- Felt channel and weatherstrip degradation. Thirty-plus years of dry, hot summers and repeated Santa Ana wind events turn felt channels brittle and weatherstrip into crumbling grey dust. The result is air infiltration, water at the sill, and sliders that take muscle to open. If the frame is sound, we re-channel and re-weatherstrip. If it’s not, we don’t waste your money patching it.
- Failed glazing seals and fogged insulated units. The later vinyl ES Windows units on 1980s-90s homes fail in a specific way here: long dry-summer UV exposure crazes the vinyl sashes while the seals between panes break down from heat cycling. Fogged glass means the insulating value is gone, and on a south-facing wall in Lake Forest, that happens faster than people expect.
- Water intrusion at flanged and stucco-embedded openings. This is the one that gets missed. Original flashing detail on these homes was not designed for today’s stucco re-coating and re-roof work. When a previous contractor re-coated stucco or re-roofed without addressing the window flashing, water finds its way in. We re-detail the opening properly.
- Stiff or seized sliders from dirt accumulation in the track. Inland Orange County’s fine dust, combined with humidity cycles in winter, packs the lower track on ES Windows sliders. The rollers grind, the track grooves, and eventually the door or window won’t move without force. Sometimes it’s a cleaning and roller replacement. Sometimes the track is gone and the frame has to come out.
ES Windows Service in Lake Forest: What Local Conditions Mean for Your Equipment
Because Lake Forest is built almost entirely on late-1960s-to-early-1990s tract homes, most of our ES Windows work here is tear-out-and-replace on original single-pane aluminum sliders still sitting in the original stucco openings, not new construction. That means matching the original rough-opening dimensions and re-detailing the stucco return and flashing is part of nearly every job we do in this city. It’s not a line item we add on when we feel like it; it’s the job.
Here’s what that looks like on the ground. On a 1970s tract home off one of Lake Forest’s older Saddleback Valley streets, our crew tore out a full run of original ES Windows single-pane aluminum sliders that were fogging, sticking, and leaking at the stucco jamb. We reframed the rough openings, re-flashed and re-detailed the stucco returns, and set new dual-pane units sized to the original openings so the exterior elevation stayed true to the neighborhood. The homeowner got quieter rooms, no more condensation, and a clean inspection pass. That job is what we mean when we say we manage the trades so you don’t have to.
Another Lake Forest reality: HOA architectural approval is a mandatory first step for most exterior construction projects here. We factor design-review timelines and CC&R restrictions into every estimate before we pull a permit. If you replace windows without that approval in certain Lake Forest communities, you’re creating a disclosure problem for every future sale of your home. We handle the paperwork and the installation in the right sequence.
ES Windows Models & Products We Service in Lake Forest
We work on the full range of ES Windows units found across Lake Forest’s housing stock. That includes the single-pane aluminum slider windows that were original builder-grade units on 1970s-80s tracts, the vinyl single-hung and double-hung replacement series, aluminum sliding glass doors and patio doors, and the fixed/picture window and horizontal slider combos common in Saddleback Valley ranch homes.
Our parts approach is straightforward. Where the existing frame is sound and the unit can be re-glazed or re-weatherstripped economically, we source OEM-equivalent ES Windows profile, glass, and hardware. When frames are corroded or out of profile, we recommend a full-frame replacement rather than patching a failing system. We tell homeowners honestly which path actually pays back on a 1970s tract home in Lake Forest. Your project. Your material choices. One contractor. Every phase.

FAQs – ES Windows Construction in Lake Forest
Yes, in most Lake Forest communities you need architectural committee approval before replacing exterior windows, even if you’re swapping like-for-like. Some CC&Rs allow like-for-like replacement of the original ES Windows single-pane units without full review if the exterior appearance matches, but many require a design review application and a waiting period before you pull a permit. We check your community’s specific CC&Rs before we quote. Call (877) 752-3154 and we’ll confirm what your HOA requires.
Yes, if the frame is still structurally sound and the track isn’t grooved or corroded, we can re-glaze, re-channel, and re-weatherstrip the original ES Windows aluminum sliders. That’s often the right economic call on a 1970s Lake Forest tract home where the frames are still straight. If the frame is corroded at the welds or the track is worn through, a repair buys you a year, not a decade, and we’ll tell you that plainly before you spend money on it.
That’s thermal bridging through the original single-pane aluminum frame combined with degraded felt channels and weatherstrip. Inland Orange County’s hot, dry summers followed by cooler nights pull condensation onto the aluminum frame, and once the felt channel is gone, the slider drags directly on the track. The fix is either re-channeling with OEM-equivalent felt and a new glazing bead, or a full replacement with dual-pane glass if the condensation is ongoing. For an exact diagnosis and quote on your specific units, call (877) 752-3154.
Yes, on full-frame replacements in Lake Forest, after the old window flange comes out, we’re usually cutting back the stucco return around the perimeter, removing any damaged substrate, re-flashing, and then re-applying and texturing the stucco to match. On a retrofit where the new unit slides into the existing frame, the stucco typically stays untouched. Both are valid depending on the condition of your existing ES Windows frames.
No. A fixed picture window or single opening is cheaper per unit than a multi-panel slider, and impact-rated units cost more than standard dual-pane. The price also shifts if we’re doing a full-frame replacement with stucco re-detailing versus a retrofit into existing frames. After we walk your Lake Forest home, you’ll get a unit-by-unit line-item quote, so you can see exactly what each opening costs. Estimates are free. Call (877) 752-3154 to schedule yours.
