ES Windows Construction in Boulder Creek, CA | Millwright Builders
We provide independent ES Windows installation, replacement, and repair across Boulder Creek, CA, including homes in the 95006 burn scar that must meet Chapter 7A wildfire-resistant construction rules. We also handle ES Windows repair in Ben Lomond and surrounding mountain communities. Most window and door work here isn’t a simple swap – it’s flash-to-the-hill, order-the-right-glass, schedule-the-narrow-road-delivery work, and that’s the part we’ve been doing for years. Call (866) 925-0334 for a straight assessment of what your ES Windows project will take.
We’re Millwright Builders, and we’ve been servicing ES Windows products across the Santa Cruz Mountains long enough to know how their vinyl frames, glass packages, and hardware behave in redwood-belt shade, heavy winter rain, and wildfire-zone sun. If you’re in Boulder Creek and your windows are fogged, sticking, or leaking, you don’t need a salesman – you need someone who can tell you whether the frame deserves a new sash or the whole opening deserves to be rebuilt. That’s the call we make every week. Reach us at (866) 925-0334 or read more about our work on this page. We also stock and service the full ES Windows line – see our ES Windows sales & service page for model details.
Why Boulder Creek Residents Choose Us for ES Windows Service
We didn’t learn window installation in a warehouse. Noel Castañeda, our owner, grew up in South San Francisco’s Sunshine Gardens neighborhood and spent nearly two decades doing residential and light commercial work across the Peninsula before founding Millwright Builders. He completed his construction trades training at Skyline College in San Bruno. That background matters when a Boulder Creek homeowner calls about an ES Windows slider that won’t latch – because the fix usually isn’t the latch. It’s the racked frame behind it, the rotted sill pan under it, or the fire-code glazing that should have been there in the first place.
We’re independent. We’re not an authorized ES Windows dealer, and we don’t pretend to be. That independence is exactly why Boulder Creek homeowners call us – we can quote an honest repair when the frame is sound, and we’ll say so directly when replacement is the only answer that survives a mountain winter. The same approach applies to our ES Windows repair in Lompico. We keep OEM sashes, glass units, rollers, and weatherstrip in our supply chain for fast turnaround, and we use quality aftermarket glazing and hardware when OEM lead times would stall a rebuild off Bear Creek Road.
Our crews work across the full building envelope, which means when we pull a window, we actually understand the wall we’re opening. We don’t have to call another contractor to fix what we find.

Common ES Windows Construction Problems We Solve in Boulder Creek
These are the issues we see most often on ES Windows products in the 95006 area. Each one ties back to the specific conditions of Boulder Creek: steep lots, redwood shade, winter rain, and the wildfire codes that now shape almost every rebuild.
- Fogged dual-pane insulated glass units. The seal fails, silica haze clouds the pane, and the window stops doing its job. We see this most often on south- and west-facing units baked by summer sun after redwood shade gets cleared for defensible space around a Boulder Creek home. Replacing the IGU is usually straightforward – but if the frame was flashed wrong originally, that fog is a symptom, not the whole problem.
- Water intrusion at sill pans and frame corners. Wind-driven winter rain pushes hard against window seals on sloped lots, and older flashing details fail. On stem-wall and pier homes in Boulder Creek, runoff can soak the wall cavity behind a window that still looks fine from inside. We repull the window, correct the flashing, and build it back to hold.
- Sticking or hard-to-latch sliders and hung windows. Redwood-damp seasonal movement racks frames, and rollers corrode from moisture that never fully dries in deep shade. Boulder Creek homes often have windows that take real muscle to open by February. We replace rollers, realign sashes, and correct the underlying frame movement where possible.
- Rot and moss creep at exterior jambs and trim. Redwood shade keeps siding damp year-round in much of Boulder Creek, and moss works its way into joints. The window itself may still operate, but the wood behind it is often softer than the homeowner realizes. We inspect the rough opening, not just the visible trim.
- Improperly flashed replacements from post-CZU rebuilds. The fire pushed a wave of replacement work through Boulder Creek, and not all of it was done to Chapter 7A standards. We regularly correct rushed flashing, wrong glass packages, and missed ember-resistant details on ES Windows units that are only a few years old.
ES Windows Service in Boulder Creek: What Local Conditions Mean for Your Equipment
The single biggest factor shaping ES Windows work in Boulder Creek is the CZU Lightning Complex burn scar. The 2020 fire burned through the 95006 zip code, and the rebuild wave that followed put a hard code layer onto window and door replacements that most flatland contractors never touch: Chapter 7A of the California Building Code. Homes rebuilt or substantially repaired inside the burn scar must use ignition-resistant construction – multi-pane tempered glazing, specific framing materials, and ember-resistant venting – and the county actually checks. A standard vinyl replacement window that would pass inspection in San Jose or South San Francisco will get knocked back on a Boulder Creek rebuild if the glass package doesn’t meet the fire code. That’s not a paperwork detail. It’s the difference between passing final inspection and redoing a window wall. We pull those Chapter 7A permits regularly, and we spec the glass to match the home’s location on the map, not just the opening size. If you’re anywhere near Bear Creek Road, Alba Road, or the deeper lots off Highway 9, you’re likely in or near a zone where this applies.
ES Windows Models & Products We Service in Boulder Creek
We install and service the full ES Windows replacement line: vinyl single-hung and double-hung units, sliding glass doors and patio door systems, horizontal sliders, casement windows, and fixed picture window units often used for mountain-view walls. Our coverage extends to ES Windows in Felton as well. For Boulder Creek specifically, we keep our parts approach honest: OEM sashes, IGU glass packages, rollers, and weatherstrip when the frame is sound; quality aftermarket glazing and hardware when OEM lead times would leave a homeowner waiting months. We don’t push repair when a frame is racked, rotted, or flashed wrong into a steep-lot wall. We say so and price the replacement. You’ll know the difference before you spend a dollar.

FAQs – ES Windows Construction in Boulder Creek
Yes, in most of the 95006 burn scar, window and door replacements must meet Chapter 7A ignition-resistant construction rules – including multi-pane tempered glazing, specific frame materials, and ember-resistant venting. The requirement applies based on parcel location, and the county verifies it at inspection. We determine whether your project falls inside the zone before we quote, so there are no code surprises later.
Fogged panes mean the insulated glass seal has failed, and in Boulder Creek the usual trigger is thermal stress – hot summer sun baking a window after defensible-space clearing removed the redwood shade that used to protect it. The fix is an IGU replacement when the frame is sound. Call (866) 925-0334 and we’ll tell you whether your frame is worth saving.
Yes. We schedule around Boulder Creek’s one-lane roads every week – we use smaller delivery vehicles for the tight turns off Highway 9, coordinate staging at the nearest wide point, and work the delivery schedule around weather, because a truck that can’t turn around is a project delay, not just an inconvenience. We plan access before the windows are ordered, not after.
If the frame is square and the track is salvageable, repair is the right call – new rollers, weatherstrip, and a realignment usually do it. But if seasonal redwood-damp movement has racked the frame or rotted the sill pan, repair won’t hold through a Boulder Creek winter, and we’ll tell you so and price replacement instead. Estimates are free – call (866) 925-0334 and we’ll look at the actual frame, not just the visible hardware.
Usually, yes. Older Boulder Creek cabins often have non-standard rough openings, so we field-measure every opening and order ES Windows units to match the existing dimensions rather than forcing a stock size into a hole that doesn’t fit. For a cabin on piers or a stem wall, we also check for slope settlement before we order, because an opening that was square in 1972 may not be square now. Call (866) 925-0334 for an exact quote on your openings.
