ES Windows Construction in Felton, CA | Seaside Contractors
We provide independent ES Windows construction service across Felton, from fogged-glass replacement on Highway 9 to full window swaps on slope-side cabins. The thing that changes the work here more than anything else: Felton sits inside CAL FIRE’s very-high fire-severity WUI mapping, which means Santa Cruz County can require Chapter 7A ignition-resistant glazing even on what looks like a simple like-for-like window replacement. That permitting reality rewrites material specs before we ever touch a rough opening. We handle that from the start. Call (833) 589-8103 if you’re weighing a repair against a replacement.
Why Felton Residents Choose Us for ES Windows Service
Glen Sorrento, our owner, came up studying building construction technology and has spent the decades since working nearly every project type the mountains and coast throw at a contractor. The ES Windows service in Ben Lomond and throughout the region happens through that general-contracting lens, not a specialty-window-only view. We see framing, flashing, siding, and fire-rated assemblies as one connected system, and when we pull an ES Windows unit on a redwood-mill cottage we’re looking at what’s behind it too. That matters on Felton’s older housing stock, where the window and the wall it sits in have often been through fifty or eighty winters together. As an independent contractor, we service and install ES Windows on the merits of the product, not because a factory program tells us to. That keeps our recommendations straight.
One contractor, every trade. It’s not just a slogan. When your ES Windows upgrade pulls siding or flashing work with it, we’re already equipped to handle that under the same roof.

Common ES Windows Construction Problems We Solve in Felton
- Fogged dual-pane insulating glass. The seal fails after repeated wet-winter and dry-summer cycling, leaving a hazy pane. We see this most on river-corridor homes near the San Lorenzo, where morning humidity swings are steeper. If the frame is still sound, we source OEM ES Windows glass and replace the IGU without tearing out the whole window.
- Water intrusion at sills and jambs. Storm-driven rain pushes against windows differently in Felton than in Scotts Valley. Original flashing on sliders and single-hungs was rarely upgraded for the kind of wind-driven rain that hits exposed Highway 9 elevations. We pull the unit, rebuild the rough opening, and flash it properly before anything goes back in.
- Vinyl frame warping and sticking sashes. South- and west-facing windows on exposed ridge lots bake in summer sun, and after enough heat cycles the vinyl can move enough to bind the sash. We inspect, adjust, and when the frame is too far gone we recommend replacing the unit rather than forcing it to work.
- Failed hardware and balances on older ES Windows units. The original balances wear out, especially on windows where screens and frames sit close to the ground and pick up moisture from untreated wood siding. We source OEM balances and hardware when it makes sense, and we’ll tell you when it doesn’t.
- Single-pane originals that need to go. A single-pane original in a Felton home is a losing fight against condensation, heat loss, and increasingly, fire-severity code. We’ll say it straight: replacement beats patching here.
ES Windows Service in Felton: What Local Conditions Mean for Your Equipment
Here’s the Felton-specific fact that reshapes most window decisions up here. Because Felton sits inside CAL FIRE’s very-high fire-severity WUI mapping, Santa Cruz County can require Chapter 7A ignition-resistant assemblies, including multi-pane tempered or laminated glazing and ember-resistant detailing, even on a window swap that would be a plain like-for-like replacement in ES Windows in Scotts Valley. So an ES Windows window order in Felton often needs upgraded glass specs before the permit gets approved. We’ve seen owners budget for a straight replacement, then learn the county is requiring laminated glass on the fire-facing elevation. That’s not a hassle we’re surprised by anymore. It’s part of the job here. We spec the glass package correctly the first time so the permit doesn’t bounce. Slope-side grading on Felton’s wooded lots can also trigger geotechnical review after a wet winter, which affects any project that touches the foundation or the wall assembly around a window opening. Tight county roads and narrow driveways off Highway 9 and along the San Lorenzo River corridor add staging and access constraints that flatland window crews never deal with. We plan for that before we show up.
On a redwood-mill cottage off Highway 9, we found two ES Windows sliders with fogged dual-pane glass and sills that had rotted from years of storm-driven rain against original flashing. We pulled the units, rebuilt and flashed the rough openings to Chapter 7A detailing, and set new ES Windows tempered-glass sliders with proper sill pans and ember-resistant trim. The owner said the difference in the river-corridor rooms was night and day once the winter rains started.
ES Windows Models & Products We Service in Felton
We work on the full ES Windows lineup: vinyl single-hung and double-hung replacement series, horizontal sliders common on mountain cabin walls, fixed and picture units paired with operable vents, and tempered- and laminated-glass units specified for fire-rated walls. The parts approach is simple. We source OEM ES Windows glass, balances, and hardware when the frame is sound. When OEM lead times or cost don’t justify it, we use quality aftermarket insulating glass or hardware and tell you which one we’re quoting and why. No mystery parts, no shortcuts on the things that keep water and embers out. For more on what we stock and what we order, see our ES Windows sales & service page.

FAQs – ES Windows Construction in Felton
Yes, when the frame is sound we can replace just the insulating glass unit with OEM ES Windows glass, keeping the existing frame in place. If the frame is warped, rotted, or the unit is a single-pane original, we’ll recommend a full replacement instead. Call (833) 589-8103 and we’ll tell you which path fits your opening.
In many cases, yes. Felton is inside CAL FIRE’s very-high fire-severity WUI mapping, and Santa Cruz County can require multi-pane tempered or laminated glazing on elevations facing wildfire exposure, even for a like-for-like swap. We check the permit requirements for your specific lot before we quote so the spec is right the first time. Call
They hold up well when they’re installed with proper flashing and drainage, which is the part that fails more often than the vinyl itself. The bigger issue we see is original flashing that was never upgraded for storm-driven rain, plus heat cycling on exposed south- and west-facing walls that can eventually warp a frame. We address both when we install.
We plan the site access before we plan the window work. That means confirming where we can stage materials, whether we need to hand-carry glass, and how to protect the surrounding trees and drainage during tear-out. It’s slower work and we price it honestly, but we’d rather do it right than wedge a truck where it doesn’t belong.
If the frame is sound and the fogging is only a failed seal, repair is usually the better financial call. If the sills show water damage, the vinyl is warping, or the unit predates current glazing standards, replacement is the smarter long-term move, especially with the fire-severity requirements Felton carries now. Call (833) 589-8103 for an honest read on your windows.
