We provide independent ES Windows construction, replacement, and repair across Felton, ZIP 95018, and the surrounding Santa Cruz Mountains.

If you’re planning a window replacement, impact-rated upgrade, or a home addition that calls for ES Windows, call (844) 681-3590 for a free estimate. We are an independent contractor, not a manufacturer-affiliated or authorized ES Windows dealer.
Why Felton Residents Choose Us for ES Windows Service
We’ve installed and serviced ES Windows across the Santa Cruz Mountains for over a decade, including ES Windows service in Ben Lomond and nearby communities, long enough to know what this product line does well and where it fails in mountain conditions. Noel Carbajal, our owner, grew up learning construction hands-on before formal training in a construction technology program, and he brings that same direct approach to every window job we take in Felton. When a Felton homeowner calls about fogged ES Windows glass or a binding sash, we’re not reading a manual. We’ve seen the failure before, usually within 15 miles of your house, and we know the fix.
What sets our ES Windows work in Felton apart is that we treat the window as part of the building envelope, not a standalone product. On a sloped lot off Graham Hill Road or along Highway 9, the window has to work with the drainage, the flashing, the fire-hardening assembly, and sometimes a settling foundation. Most window crews never get past the frame. We look at the whole opening, which is why ES Windows sales & service through Framework Contractors includes a full site assessment before any work begins.

Common ES Windows Construction Problems We Solve in Felton
ES Windows builds a solid product, but Felton’s environment exposes weak points. These are the issues we see most often:
- Corrosion and pitting on aluminum-clad sills. On Felton’s older redwood-era cabins, ES Windows aluminum-clad units often show pitting along the sill and bottom rail where winter rain and redwood tannins trap moisture. This is specific to the redwood belt. Homes off Highway 9 with original redwood siding are particularly prone, since tannins leach onto the metal and accelerate corrosion over wet winters.
- Failed glazing seals causing fogged glass. South- and west-facing ES Windows dual-pane units in Felton take intense mountain sun through most of the dry season. We routinely find failed seals on those exposures, which means fogging between panes and lost insulating value. The glass itself is rarely the problem; it’s the seal that gave out after years of UV and thermal cycling.
- Out-of-square frames from settling foundations. Many Felton homes have unpermitted additions built on pier-and-post foundations that shift over time. ES Windows installed without proper shimming and flashing on those walls develop binding sashes and air infiltration as the opening moves. This is not a window defect. It’s a foundation issue that shows up in the window, and it needs a contractor who understands both.
- Ember entry behind poorly sealed trim. In fire-hardened zones, ES Windows’ tempered glass and ember-resistant screens only work if the exterior trim is sealed tight. We’ve found homes in Felton where embers could lodge behind the frame because the original install left gaps. Cal Fire’s defensible-space rules make this a code issue, not just a comfort issue.
- Water intrusion at the head flashing. Felton’s heavy winter rainfall exposes any flashing shortfall quickly. ES Windows units with improper or missing head flashing leak into the rough opening, and on older cabins the water follows the framing and shows up as rot at the sill years later. By the time you see interior staining, the repair scope has usually grown.
ES Windows Service in Felton: What Local Conditions Mean for Your Equipment
Here’s what shapes ES Windows work in Felton more than anything else: the WUI fire-hardening rules and steep, wooded lots. A ES Windows in Scotts Valley or San Jose installer orders units, swaps them in, and drives away. In Felton, an ES Windows installation often requires custom flashing details and tempered glazing beyond standard code, because the county’s wildland fire code and defensible-space rules govern what glass, what frame materials, and what sealing methods are allowed on any remodel. Add a slope under redwood canopy and the job can trigger a geotechnical report or retaining-wall engineering before a single window gets ordered. We plan for that on the first visit. Nobody wants a window project stalled because the plans didn’t account for Cal Fire clearance or hillside drainage.
ES Windows Models & Products We Service in Felton
We work with the full residential ES Windows lineup: the Essential Series, the Impact Series, and the WoodClad Series. When a frame is sound and the unit is under 15 years old, we source OEM ES Windows replacement sashes, hardware, and weatherstripping to keep the original fit. When the frame is rotted or multiple glazing seals have failed, we match profiles with high-quality aftermarket components that meet or exceed original specs and quote a replacement instead. Our rule of thumb: repair when the frame is square and watertight, replace when the frame is compromised or the fogging is widespread. For Felton homeowners deciding between repair and replacement, or those seeking ES Windows service in Mount Hermon, the WUI requirements usually tilt the decision toward new impact-rated units, especially on south- and west-facing walls.

AfterES Windows Service Pricing in Felton
Window replacement in Felton typically falls between $4,500 and $15,000 depending on the number of units, the ES Windows series selected, and what we find in the rough openings once the old windows come out. Impact-rated installation runs higher, generally $8,000 to $25,000, because the glass, frames, and sealing requirements are more demanding under WUI code. A home addition with ES Windows starts around $45,000 and can reach $130,000 depending on foundation work, site access, and hillside engineering. Every free estimate includes a written line-item quote, so you’ll see exactly where the money goes before you sign anything. Call (844) 681-3590 to schedule a site visit in Felton.

FAQs – ES Windows Construction in Felton
Felton sits inside a Wildland-Urban Interface zone, which means Santa Cruz County’s fire code and Cal Fire’s defensible-space rules set minimum standards for glazing, frame materials, and ember resistance on any new or replacement window. In practice, this usually means tempered glass on exterior-facing elevations, ember-resistant screens where required, and fire-rated sealing at the trim and flashing. ES Windows Impact Series units are often the cleanest path to compliance, but not every opening needs the full impact-rated assembly. We review your specific parcel and elevation during the free estimate and specify only what the code requires. Call (844) 681-3590 and we’ll walk the property with you.
Sometimes. If the ES Windows frame is square, watertight, and in good structural condition, replacing the insulated glass unit is a legitimate repair, and we source the replacement through OEM channels where available. But on Felton cabins with 50-year-old frames, the aluminum often shows corrosion from redwood tannins and decades of wet winters, and the glazing seals on multiple panes tend to fail around the same time. In that situation, glass replacement is throwing money at a system that’s already degrading. We’ll tell you straight which side of the line your windows fall on, and give you a written repair quote and a replacement quote side by side. Call (844) 681-3590 for the full assessment.
They require a different installation approach, yes. On a sloped Felton lot with retaining walls, the window openings are often in walls that move slightly with seasonal soil expansion and contraction. ES Windows installed rigidly in those openings will bind over time. We shim and flash differently on hillside work, leaving tolerance for minor movement and using drainage details that direct water away from the rough opening. If a retaining wall is failing or the foundation is settling, we’ll flag it before touching the windows, because windows installed into a structural problem will not perform, no matter the brand.
For a typical Felton home, ES Windows replacement runs $4,500 to $15,000 depending on window count, series, and whether the openings need repair. Impact-rated ES Windows run higher, $8,000 to $25,000, which reflects the tempered glass, ember-resistant screens, and stricter sealing that WUI code requires. Homes with foundation settling or rotted rough openings will fall in the upper end of the range. The exact number depends on your walls, not your neighbor’s. Call (844) 681-3590 and we’ll give you a written line-item estimate after one site visit.
We can, and this is where ES Windows’ WoodClad Series earns its place. Many Felton homes are redwood-era cabins with a specific look, and WoodClad units let us match the wood interior finish while keeping the durable aluminum exterior that stands up to mountain weather. A home addition in Felton typically runs $45,000 to $130,000 depending on foundation type, site access on the slope, and whether the county requires a geotechnical report. We handle the engineering, the permits, and the window specification as one scope of work. Call (844) 681-3590 to talk through your addition.
