ES Windows Construction in Boulder Creek, CA | Gold Star Contractors
We provide independent ES Windows construction, replacement, and repair service throughout Boulder Creek and the surrounding Santa Cruz Mountains. The one thing that makes our ES Windows work here different is that we plan every job around Boulder Creek’s unique access realities: narrow private lanes, steep driveways, and CAL FIRE wildland-urban interface (WUI) building standards. If you need ES Windows installed, serviced, or assessed for fire hardening, call (833) 382-8544 for a free estimate.

Our ES Windows sales & service expertise covers the 2000 Series aluminum single-hung, 4500 Series vinyl double-hung, 8000 Series casement, and the sliding glass door line. As a full-scope general contractor, Gold Star Contractors specifies the brand, manages the install, and stands behind the result. One contractor. Every system. No handoff gaps.
Why Boulder Creek Residents Choose Us for ES Windows Service
Noel Carranza, our owner and general contractor, has spent years on job sites where the difference between a good window install and a failing one comes down to flashing details, sealant choice, and knowing what the mountain weather will do to a frame over time. That’s the knowledge we bring to every ES Windows service call in Boulder Creek.
We are not an ES Windows authorized dealer or manufacturer affiliate. We’re an independent service provider, which means we give you straight repair-versus-replace assessments without a sales quota behind them. If a sash balance or roller replacement gets your window working again, we’ll tell you that. If the frame is compromised, we’ll tell you that too. Our crew sources OEM ES Windows parts whenever they’re available and uses high-quality aftermarket equivalents for obsolete components. Your home is too important to coordinate five different contractors for windows, flashing, and siding work that all touch the same opening.

Common ES Windows Construction Problems We Solve in Boulder Creek
- Corroded and pitted aluminum frames on 2000 Series windows. Boulder Creek’s wet winters and coastal fog hit north-facing walls hardest. Older ES 2000 Series aluminum frames corrode and pit under that moisture load, especially where redwood debris sits against the frame. We remove the corrosion, repair or replace damaged sections, and reseal with WUI-compliant flashing.
- Warped vinyl frames on 4500 Series double-hungs. Intense summer sun and heat cycling cause vinyl frames to warp and lose seal integrity. On exposed ridgeline properties in Boulder Creek, we regularly find 4500 Series windows with air infiltration where the sash no longer seats square. Repair means either refitting the sash within tolerance or replacing the unit.
- Fogged glass from factory glazing seal failure. Driving rain on exposed ridgeline lots in Boulder Creek shortens the life of factory glazing seals. Once the seal fails, moisture gets between the panes and you get permanent fogging. We replace the insulated glass unit and address the flashing detail that let water sit against the frame in the first place.
- Binding sliding glass doors from redwood needle debris. ES sliding glass door rollers and tracks bind and corrode when redwood needles, seasonal moisture, and mountain grit work into the track. We clean the track, replace worn rollers, and adjust the door so it moves smoothly again. Sometimes the track itself needs replacement.
- Ember intrusion risk on older ES window assemblies. In WUI zones, the gap between frame and wall matters. Older ES window installations in Boulder Creek often lack ember-resistant sealing. We retrofit with intumescent sealants and ignition-resistant flashing that meet current CAL FIRE standards, without replacing the entire window unless the frame demands it.
ES Windows Service in Boulder Creek: What Local Conditions Mean for Your Equipment
Boulder Creek’s narrow, unmaintained private lanes and steep driveways often prevent standard delivery trucks from reaching job sites. That means an ES Windows replacement project here is not a simple curb-drop delivery. We coordinate smaller delivery vehicles, stage materials at the bottom of the hill, or schedule around a neighbor’s shared driveway access. Before the first permit is pulled, we’ve already figured out how every window gets from the truck to the opening. That logistical planning is the difference between a two-day job and a two-week one.
On a steep, redwood-shaded lot off Bear Creek Road, we handled ES Windows repair in Ben Lomond and nearby areas, replacing a set of failing ES Windows 4500 Series double-hung units that had warped frames and fogged glass after years of sun and moisture cycling. We coordinated a small flatbed delivery to the neighbor’s shared driveway, then hand-carried each window up the slope, installing new units with WUI-compliant flashing and ember-resistant sealing. The homeowner now has clear glass, smooth operation, and a tighter building envelope heading into fire season. That’s ES Windows construction work in Boulder Creek: it’s about access and hardening, not just swapping glass.
ES Windows Models & Products We Service in Boulder Creek
We service the ES Windows 2000 Series aluminum single-hung, the 4500 Series vinyl double-hung, and the 8000 Series casement, plus the ES sliding glass door series. Our parts approach is straightforward: we source OEM sash balances, glazing beads, rollers, and locks when the manufacturer still makes them. For older models where ES parts are discontinued, we use aftermarket equivalents that meet or exceed the original specs. We keep common ES-compatible hardware stocked for faster Boulder Creek turnaround, so you’re not waiting on a specialty order for a basic roller or balance replacement.
When replacement is the right call, we also specify and install performance-grade fenestration across our full brand portfolio, including PGT, CGI, CWS, and ECO Window Systems alongside ES Windows. Premium materials, professionally installed, with the technical knowledge those brands demand.

FAQs – ES Windows Construction in Boulder Creek
Yes. We plan the delivery around your road’s actual width and grade, using smaller trucks, staging areas at the base of the hill, or a neighbor’s shared driveway when access is tight. We’ve done it on Bear Creek Road, down to hand-carrying windows up a slope. Call (833) 382-8544 and we’ll walk your site before we quote.
ES Windows can perform well in WUI zones, but the installation details determine that more than the glass itself. Ember-resistant sealing, ignition-resistant flashing, and proper frame-to-wall integration are what make any window fire-hardened. We install ES units with those WUI details and can retrofit older ES assemblies to current CAL FIRE standards for customers seeking ES Windows in Felton and surrounding mountain communities. We’ll assess your specific exposure during the estimate.
Most of the time, it’s repairable. Roller replacement, track cleaning, and adjustment fix the majority of binding doors we see in Boulder Creek, where redwood needle debris and moisture gum up the track. If the track itself is corroded through or the door frame has shifted out of square, we’ll show you why replacement is the better spend. Our assessment is honest either way.
We schedule window work around storms whenever possible, because sealants and flashing need dry conditions to cure properly. The wet winter months also expose existing flashing failures, so it’s a good time to catch problems before they rot the framing. We plan installation windows in the dry gaps and do storm-damage assessments year-round.
Yes, we respond to storm-damaged windows in Boulder Creek, especially after a wet winter event or windstorm blows debris into glass or pulls flashing loose. If you have a broken pane or a window that won’t close after a storm, call (833) 382-8544 and we’ll get you on the schedule. If the damage is extensive enough to need full replacement, we’ll quote that on the spot.
