ES Windows Construction in Berkeley, CA | Rowan Construction Group Oakland
We provide independent ES Windows service across Berkeley, from fog-belt bungalows in the flatlands to Tunnel Fire rebuilds in the hills. The one thing that makes our ES Windows work here different is seismic literacy: we know when a window replacement in the Berkeley Hills triggers a geologic hazard investigation under Alquist-Priolo, and we build that timeline into the quote so you’re not surprised at permit. Call ES Windows sales & service at (628) 300-4376 for a free written estimate.
Why Berkeley Residents Choose Us for ES Windows Service
We’ve installed and repaired ES Windows products across Berkeley since 2007, and we’ve learned how the 3000 Series single-hung behaves in a 1910 Craftsman on a shallow perimeter foundation versus how the 7000 Series casement holds up in a 1993 Tunnel Fire rebuild on Grizzly Peak - experience that informs our Kitchen Remodeling in Berkeley work as well. Grant Rowan, who grew up in Beverly Hills and cut his teeth in Santa Monica College’s construction technology program before spending two decades running jobs across the East Bay, including extended work in Fruitvale, built this crew on tight scopes: line-itemized estimates, material specs with brand and model noted, documented inspections at each phase. That’s the Haven Standard.
We are not affiliated with or authorized by ES Windows. Our credibility comes from field experience, not a badge. We source OEM sashes, rollers, weatherstripping, and hardware when the original profile is still in production; for discontinued units, we match aftermarket components to the existing extrusion. Every written quote arrives before any work starts, per Clause 1. Every change requires a signed change order. And every visit leaves you with a documented photo record, included as standard.
Common ES Windows Construction Problems We Solve in Berkeley

- Glazing seal failure in fog-belt homes. The marine layer that blankets Berkeley’s flatlands west of Martin Luther King Jr. Way keeps vinyl frames chronically damp. On west-facing ES Windows 3000 Series units, we’ve found butyl glazing tape that degraded in 18 years instead of the expected 25, letting condensation migrate into the wood framing below. We don’t just replace the glass; we inspect the sill for rot and document it.
- Vinyl frame warping in Berkeley Hills sun exposure. South- and west-facing elevations above the fog line get intense summer heat. We’ve replaced ES Windows 5000 Series sliding doors in the hills where the vinyl rail had bowed enough to bind the roller track, usually in homes built between 1992 and 1996.
- Hardware corrosion from salt air intrusion. Homes within a few blocks of the bay pick up marine aerosol that pits ES Windows 7000 Series casement operators and awning hinges. We stock stainless-steel aftermarket hardware for these cases, or source OEM when the part number is still active.
- Impact rating gaps in WUI zones. The Berkeley Hills fall within California’s Wildland-Urban Interface designation, and many ES Windows units installed before 2008 lack the impact resistance or ember-resistant venting now required for permitted renovation. We flag this during estimate so the permit application is complete the first time.
- Foundation movement stressing fixed picture units. In the flatlands, shallow perimeter foundations on Bay Mud let structures drift slightly during winter saturation cycles. ES Windows 8000 Series fixed picture windows, which don’t open to relieve stress, can develop corner seal cracks. We check for frame racking before quoting glass-only replacement.

AfterES Windows Service in Berkeley: What Local Conditions Mean for Your Equipment
Berkeley sits directly atop the Hayward Fault, and the city’s mandatory seismic retrofit ordinances for soft-story buildings and unreinforced masonry structures make compliance-driven upgrades a dominant engine of local construction. No neighboring city combines Alquist-Priolo Fault Zone restrictions in its residential hills, a post-1991 Tunnel Fire rebuild layer, and citywide retrofit mandates the way Berkeley does. For ES Windows owners, this means replacement work in the hills often ties to broader compliance upgrades, not just failed glass - similar to how our Bathroom Remodeling - Berkeley projects integrate seismic and code requirements. A large share of Berkeley Hills homes rebuilt after the 1991 Tunnel Fire were required to use Class-A fire-resistant roofing and ember-resistant vents, and many of those same rebuilds used ES Windows units that are now 30+ years old. When we quote replacement on those homes, we’re typically specifying units with improved thermal performance and installing ember-resistant flashing detail around the opening, because the WUI designation doesn’t grandfather in old construction. Out-of-town contractors miss this routinely. We don’t.
ES Windows Models & Products We Service in Berkeley

We work on the full ES Windows residential lineup: the 3000 Series Vinyl Single-Hung, common in flatlands bungalows; the 5000 Series Vinyl Sliding Glass Door, often found in hillside homes with deck access; the 7000 Series Casement and Awning, which ventilate well in the hills but need hardware rated for the exposure; and the 8000 Series Fixed Picture Window, popular in post-Tunnel Fire rebuilds for its clean sight lines. We stock common OEM replacement parts for units still in production, including sashes, rollers, weatherstripping kits, and lock mechanisms. For discontinued profiles, we machine-match aftermarket components rather than forcing a full-unit replacement. That said, when the frame or glazing seal is compromised after 25+ years in Berkeley’s fog belt, we’ll tell you straight: repair costs approach replacement value, and the written quote will show both numbers.

Our free estimate includes a full opening inspection, photo documentation of what we find, and a written scope with flat price. No work starts until you’ve seen the number in writing.

FAQs - ES Windows Construction in Berkeley
Yes, if your property lies within approximately 50 feet of the mapped Hayward Fault trace under the Alquist-Priolo Earthquake Fault Zone Act. The city of Berkeley will not issue a building permit for any construction project in that buffer without a site-specific geologic hazard investigation. This step routinely blindsides out-of-town contractors but is standard operating procedure for experienced local builders. We verify fault proximity during our initial site visit and build the investigation timeline into your written quote. Call (628) 300-4376 and we’ll check your address.
The insulating glass unit (IGU) seal has failed, allowing moist air to enter the space between panes. In Berkeley’s flatlands, the persistent marine layer accelerates this by keeping exterior frame temperatures low and creating a thermal gradient that stresses the seal. Once the desiccant inside the IGU is saturated, fogging becomes permanent. We replace the IGU or the full sash depending on frame condition, and we inspect the sill for moisture intrusion while the unit is out. Call (628) 300-4376 for an exact quote - estimates are free.
We can replace a single unit. Many Berkeley homeowners start with one failed window and expand the scope once they see the written quote and photo documentation. On a narrow street in the Berkeley Hills, we replaced a failed ES Windows 3000 Series single-hung in a 1992 Tunnel Fire rebuild where the vinyl frame had warped from years of west-facing sun and the glazing seal had failed. The homeowner later asked us to quote the remaining seven windows on the same elevation. No pressure, just numbers in writing.
Many ES Windows units meet WUI requirements when properly specified with impact-rated glazing and ember-resistant venting. The key is matching the product to the specific ignition-resistant construction standards that apply to your hillside zone. We verify WUI classification during estimate and specify accordingly, because an inspector will flag non-compliant materials before final sign-off. Call (628) 300-4376 and we’ll walk your property.
Soft-story retrofits focus on ground-floor weakness, but the ordinance often triggers full-building energy and seismic reviews that include window anchorage and egress requirements. If your ES Windows units are original to a pre-1978 soft-story building, the retrofit may require tempered glass, larger egress openings, or enhanced anchorage to the cripple wall. We coordinate with your structural engineer and the city’s Building & Safety Division to make sure the window spec matches the retrofit plan before we order. Call (628) 300-4376 to review your retrofit documents.
