ES Windows Construction in Highland Park, CA | Rowan Construction Group Pasadena
ES Windows construction service in Highland Park, CA runs $4,500-$25,000 depending on whether you’re replacing existing units, upgrading to impact-rated glass, or integrating windows into a larger addition. What separates our work here from standard window jobs across the Arroyo Seco is the HPOZ - Highland Park’s Historic Preservation Overlay Zone adds a design-review layer that rejects stock vinyl specs on street-facing Craftsman facades, so we verify clearance before we order a single sash. Call (562) 203-4508 to schedule your free estimate; we bring written pricing, not a verbal range.
We’re an independent contractor, not authorized or endorsed by ES Windows. We source OEM and OEM-equivalent parts directly and tell homeowners that plainly before any work begins. Our crews have replaced and repaired ES Windows in Highland Park’s 1920s bungalows and hillside cottages for years, working with the model lines that actually appear in this housing stock - the Vinyl Series 3000 single-hungs, the V-Series double-hungs, aluminum awning units, and the sliding glass door series. Grant Rowan, who grew up in East Los Angeles and learned framing and finish work at Los Angeles Trade-Technical College before pulling his first permit, has been building in these neighborhoods for over fifteen years. He knows the difference between a stop-work order and a closed permit, and he prices the work accordingly.
Why Highland Park Residents Choose Us for ES Windows Service
Highland Park homeowners tend to research contractors the way they research appliances - they read the three-star reviews, they want the price range on the page, and they prefer a text confirmation to a phone promise. We build our process around that.
Every ES Windows project starts with a written scope before any conversation about price. Line items in plain English, material brands named, labor and materials separated so you can see exactly what you’re paying for. That’s Clause 1 of the Haven Standard, the administrative discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007. No change proceeds without a signed change order. The quote you receive is flat, with a written warranty, and we deliver it before anyone picks up a tool.
Our technicians are background-checked and uniformed. A live person answers calls 24/7. Every visit includes a documented photo record - standard, not an upgrade - so you leave with evidence of what we found and what we did. And our 365-Day Done Right Promise means if it is not done right, we make it right, backed by a terms page you can read, not an asterisk.
We also offer a Free Second Opinion on any written estimate. Bring a competitor’s quote and we’ll review it line by line at no charge. “Write it down before you build it - scope first, surprises later.” That’s how Grant Rowan runs every job, whether it’s a single window replacement on Figueroa Street or a full home addition off York Boulevard - or Kitchen Remodeling in Highland Park.
Common ES Windows Construction Problems We Solve in Highland Park

- Failed vinyl sash balances on Series 3000 single-hungs. Highland Park’s Craftsman bungalows were built between 1905 and 1930, and the original rough openings were rarely plumb. The sash racks against the frame for decades, eventually wearing out the balance mechanism. We replace with OEM-spec balances sized to the exact sash weight, not universal aftermarket kits that bind within a season.
- Perished glazing gaskets and seals on aluminum units. Repeated El Niño rain cycles in the Arroyo Seco watershed degrade the gasket material on ES Windows aluminum awnings and fixed units. Water tracks behind the stucco at head and sill, often hiding rot until the frame is opened. We replace gaskets with OEM-equivalent silicone profiles and flash properly - caulk is not flashing.
- Fogged insulated glass units on V-Series double-hungs. South and west elevations in Highland Park take heavy afternoon heat, which drives thermal pumping in the IGU seal. Once the desiccant saturates, the glass fogs permanently. We measure the existing IGU and order a direct replacement from the parts channel, or specify a new unit if the frame has degraded.
- Corroded or seized rollers on sliding glass doors. Hillside lots in Highland Park often have drainage issues that keep the track pan wet year-round. ES Windows sliding door rollers seize, then homeowners force the door and bend the track. We stock OEM rollers and track sections for faster turnaround, and we address the drainage before reinstalling.
- Cracked or brittle vinyl frames from earlier remodels. ES Windows units installed during the last decade’s gentrification wave sometimes lacked proper flashing at the nailing fin. Combined with seismic movement on Highland Park’s cut-and-fill lots, the vinyl corners stress-crack. We assess frame integrity honestly - repair if sound, replace if the water intrusion has compromised the substrate.
Before
AfterES Windows Service in Highland Park: What Local Conditions Mean for Your Equipment
Highland Park sits within one of Los Angeles’s largest Historic Preservation Overlay Zones, and that single fact rewrites how ES Windows replacement works here. The HPOZ design standards explicitly prohibit non-historic cladding materials on contributing structures - smooth stucco, vinyl windows, and T1-11 siding on street-facing facades will fail design review, which is why Bathroom Remodeling in Highland Park also requires careful material selection. Contractors who standard-spec these materials and pull permits without HPOZ clearance first routinely get stop-work orders.
For ES Windows owners, this means a street-facing replacement on a 1912 Craftsman bungalow off York Boulevard or any contributing structure in the HPOZ usually cannot be the stock vinyl spec that would sail through in Glassell Park or El Sereno. We typically specify wood-clad or aluminum-clad units that match the existing trim profile, then submit for HPOZ compatibility approval through the City’s Office of Historic Resources before we order glass. We also have to meet modern LA seismic and Title 24 energy codes simultaneously - a balancing act that defines nearly every project. A stop-work order on a window job means a house open to the weather, so we pull clearance first. That’s not bureaucracy; it’s weather protection.
ES Windows Models & Products We Service in Highland Park

We work with the full ES Windows product range that appears in Highland Park’s housing stock. The ES Windows sales & service we provide covers:
- ES Windows Vinyl Series 3000 - single-hung and slider configurations, common in 1990s-2010s additions and ADUs
- ES Windows V-Series - double-hung vinyl units, frequently found in hillside cottages and front-facade replacements
- ES Windows Aluminum Series - awning and fixed units, often specified for HPOZ-compatible street-facing installations
- ES Windows Sliding Glass Door series - including roller, track, and lock hardware replacement
We go straight to OEM or OEM-equivalent components - sashes, balances, rollers, gaskets, and IGUs - because the frames are engineered around those dimensions. Aftermarket substitutes tend to leak or bind within a season. We stock common rollers and gaskets locally for faster Highland Park turnaround, and we order IGUs and complete sashes directly from the parts channel with typical lead times of 10-14 business days. We’ll repair a sound frame all day, but once the vinyl is cracked or a hillside unit has taken on water behind the flange, we say so and price a replacement instead of pretending a patch will hold.
ES Windows Service Pricing in Highland Park
Our ES Windows work in Highland Park falls into three main categories, with pricing driven by unit count, access difficulty on hillside lots, and whether HPOZ-compatible materials are required for street-facing facades.
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
| Home Addition (including window integration) | $45,000 - $130,000 |
What moves the number: unit count and size, whether the existing frames are square (they often aren’t in pre-1930 construction), hillside access requiring scaffolding or boom equipment, HPOZ material upgrades from vinyl to wood-clad or aluminum-clad, and the condition of the rough opening once the old unit is out - rot repair adds labor and materials but prevents callbacks. Every estimate includes a written scope with line-item pricing, material brands named, and labor separated from materials so you can compare apples-to-apples. Call (562) 203-4508 for your exact quote - estimates are free, and we deliver the number in writing before any work starts.

FAQs - ES Windows Construction in Highland Park
Yes, but the replacement must pass HPOZ design review first. Stock vinyl units on contributing Craftsman structures will be rejected; we typically specify wood-clad or aluminum-clad ES Windows units that match the existing trim profile, then submit for compatibility approval before ordering. Call (562) 203-4508 to schedule a site visit and we’ll assess your facade’s contributing status.
Fogged IGUs are a repair if the frame is sound and the fogging is limited to the glass pack. We measure the existing IGU and order an OEM-equivalent replacement. If the frame corners are cracked or water has compromised the rough sill, we recommend full unit replacement with proper flashing. Call (562) 203-4508 and we’ll open the frame to determine which path applies.
Yes. Cut-and-fill and steep-slope parcels in the Arroyo Seco watershed often require geotechnical reports and retaining wall permits before window work on lower-level units, and drainage issues keep track pans wet on sliding glass doors. We assess slope stability and drainage as part of every hillside estimate. Call (562) 203-4508 for a site-specific evaluation.
Yes, provided the units meet the current U-factor and SHGC requirements for your climate zone. ES Windows vinyl and aluminum lines carry NFRC ratings; we specify the appropriate performance grade for Title 24 compliance and document it on the permit submittal. The HPOZ material constraints may limit your options, but compliant units exist in wood-clad and aluminum-clad configurations.
Common hardware - rollers, balances, gaskets - we stock locally and can often install within a few business days. IGUs and complete sashes typically ship from the parts channel in 10-14 business days. We verify HPOZ clearance before ordering to avoid delays from permit holds. Call (562) 203-4508 to check current lead times for your specific model.
