ES Windows Construction in Bonny Doon, CA | Moreno Valley Builders
We provide independent ES Windows construction and replacement service throughout Bonny Doon, and the thing that separates our work here is simple: we plan around steep driveways, narrow mountain roads, and Santa Cruz County’s wildfire codes before we ever unload a window. If you own an ES Windows 4000 Series slider, 2000 Series single-hung, or 8000 Series patio door, we handle repair, retrofit, and full replacement on the same rough openings. Call (877) 752-3154 for a free estimate and we’ll walk the site with you.
Why Bonny Doon Residents Choose Us for ES Windows Service
We’re a general contractor, not a window-only outfit, and that matters in Bonny Doon more than most places. Window work here rarely stops at the window. A fogged unit on a 1980s contemporary usually means a rotted sill, a tweaked rough opening, or a water-intrusion path that’s been quietly eating the sheathing for years. Noel Trevino, our owner, has spent decades going behind other contractors’ shortcuts and fixing load paths, flashing details, and framing that should have been right the first time. He’ll tell you the same thing on a Pine Flat Road hillside as he would on a Moreno Valley slab: if the details aren’t right on paper, they won’t be right in the wall.
We source OEM ES Windows parts when they’re available, and we stock the rollers, weatherstripping, and glazing seals that fail most often in this climate. Being independent means we’re not bound to one product line or one way of doing things. Our ES Windows sales & service work covers the full spectrum: a targeted roller replacement on a 4000 Series slider, a full re-glaze on a 2000 Series, or a complete pull-and-replace when fire code says it’s time.

Common ES Windows Construction Problems We Solve in Bonny Doon
- Corroded aluminum tracks on 4000 Series sliders. Fog-borne salt and months of winter rain pit the track surfaces until the rollers bind and the sash drags. We see this on west-facing units most often, where moisture hangs against the frame. We replace rollers, dress the track, and add the correct drainage weep paths so it doesn’t return next season.
- Warped vinyl frames and fogged glass on 2000 Series single-hungs. South and west exposures cook the vinyl until the frame bows and the seal fails. Glass fogs, water gets behind the frame, and the unit goes from nuisance to structural problem. We replace the sash or the full unit, depending on how far the warp has traveled.
- Missing sill-pan flashing on 1970s-90s ES Windows installations. Older redwood-era cabins in Bonny Doon often have original windows set directly on rough framing with no sloped sill pan. Winter storms drive water under the frame and into the sheathing. We rework the opening, install a proper pan, and seal the perimeter before the new unit goes in.
- Non-ember-resistant screens and single-pane glazing failing WUI compliance. Santa Cruz County’s wildfire code has moved faster than a lot of old window packages. If the unit has vinyl screens, plastic trim, or un-tempered single glazing, it can hold up your rebuild or retrofit permit. We swap in multi-pane tempered glazing and metal screens that meet current defensible-space requirements.
- Out-of-square rough openings from settling foundations. Pier-and-beam homes shift over decades on sloped lots. We routinely square openings, shim and back-caulk properly, and re-flash before installing the new ES Windows unit. A window is only as square as the hole it sits in.
ES Windows Service in Bonny Doon: What Local Conditions Mean for Your Equipment
If you live off Empire Grade or Pine Flat Road, you already know the roads don’t forgive a lazy delivery estimate. Standard window trucks and flatbeds often cannot make the final turn or climb the grade, so we offload at the nearest paved switchback and hand-carry or shuttle units by small vehicle to the build site. That’s not a side detail; it changes how we sequence the job, how many crew members we send, and how we protect the glass during the carry. A 6-foot patio door panel weighs enough without adding a muddy hillside and a 15% slope. We learned that the expensive way years ago, and now every Bonny Doon scheduling call starts with the same question: what’s the last hundred feet to your door actually like?
That logistics layer is why we say this page should exist: a generic ES Windows guide has nothing to say about defensible space, WUI glazing requirements, or whether a delivery truck can reach your driveway. Those are the things that actually decide whether your window project in Bonny Doon goes smoothly.
ES Windows Models & Products We Service in Bonny Doon
We work on the full ES Windows residential line: 4000 Series aluminum sliders, 2000 Series vinyl single-hungs, and 8000 Series vinyl patio doors, along with earlier-generation units still hanging in older Bonny Doon cabins. For parts, we source OEM rollers, weatherstripping, and glass when available, and we keep a working stock of common failure parts for fast turnaround up here. When OEM parts are discontinued or priced off the lot, we use proven aftermarket seals and glazing and tell you exactly what we’re using and why. You’ll never hear us pretend a $40 aftermarket roller is the same as OEM; we’ll give you the honest trade-off and let you decide. Our ES Windows sales & service work is built on that plain-spoken approach.

AfterES Windows Service Pricing in Bonny Doon
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Replacement | $8,000 – $20,000 |
The spread in window pricing comes down to glass size, number of units, whether impact-rated glazing is required, and what we find when we open the wall. A straight sash replacement on a 2000 Series single-hung runs on the lower end. A full-frame replacement with WUI-compliant impact glazing and re-flashing runs higher. Our free estimate includes a site walk, a look at the existing flashings and rough openings, and a written line-item quote. Call (877) 752-3154 and we’ll get it scheduled.

FAQs – ES Windows Construction in Bonny Doon
Window replacement that stays in the existing rough opening typically falls under a standard building permit, but two Bonny Doon factors can add review: wildfire zone requirements and historic or geotechnical overlay districts. If the work triggers WUI glazing or screening upgrades, the permit will note it. We’ll pull the permit and handle the inspection.
Fog carries salt and moisture that settles on aluminum tracks and frame edges, accelerating corrosion and pitting. The fix is more than just a replacement roller; we’ll address drainage and reseal the frame so the next unit isn’t fighting the same conditions. Call (877) 752-3154 for an assessment if your sliders are dragging or leaving streaks on the glass.
If the frame is sound and the seal failure is contained, we can often replace the insulated glass unit itself. If the frame has warped, the sash is compromised, or the unit is fighting WUI compliance, full replacement is the better investment. We’ll give you an honest repair-versus-replace call after looking at the unit.
Multi-pane tempered glazing with metal screens and ember-resistant vents is the standard we recommend, and Santa Cruz County increasingly requires it for rebuilds and major retrofits. If your ES Windows units still have vinyl or plastic screens, plan on upgrading those when you replace the glass. We’ll spec the right package for your permits.
We offload at the nearest accessible turn and carry or shuttle units the rest of the way. We’ve done it on Pine Flat Road properties, on Empire Grade switchbacks, and on driveways a full-size truck never could. It adds time and care, but it’s the only way to get glass up some of these hills. Call (877) 752-3154 for an exact quote on your site; estimates are free.
