ES Windows Construction in Pomona, CA | Workshop Contractors
We provide independent ES Windows in La Verne and construction and service across Pomona, and we’ve been doing it long enough to know that the real work here happens behind the stucco. On pre-war bungalows with pier-and-beam foundations and on 1950s tract homes with original single-pane sliders, the window opening is rarely square and seldom dry. We spec the unit and the flashing to what we actually find when we open the wall, not to what the brochure assumes. Call Noel and the team at (844) 384-3361 to schedule a free estimate.
Why Pomona Residents Choose Us for ES Windows Service
Workshop Contractors is a General Contractor – Pomona led by Noel Figueroa. Noel grew up in the Vineyard neighborhood of Ontario, learned framing and job-site fundamentals through Chaffey College’s construction technology program, and has spent decades since working across the Inland Empire on everything from ground-up residential builds to full commercial tenant improvements. His grandfather built the family’s house in Pomona with his own hands, which is the kind of personal history that keeps us honest about what holds up and what doesn’t.
We’re not affiliated with, authorized by, or endorsed by ES Windows. What we are is the crew that has removed, re-flashed, re-set, and replaced ES Windows repair in Montclair and across the Pomona Valley enough times to know their failure patterns by elevation, by era, and by neighborhood. We carry a strong local inventory of ES OEM replacement sashes, glass packs, and hardware, and we bring aftermarket sealed units and weatherstripping when the OEM channel is slow or discontinued. Most Pomona jobs don’t need a full tear-out. When they do, we’ll tell you straight and show you why in the wall.

Common ES Windows Construction Problems We Solve in Pomona
- Fogged sealed units on east and west exposures. Original ES single-pane and early dual-pane units lose their argon and desiccant seal after enough Pomona heat cycling. Fogging between the panes is the most common call we get from Lincoln Park and Wilton Heights homeowners. We reglaze with correct-size sealed units when the frame is sound, and replace the sash when it isn’t.
- Binding vinyl sliders and dried-out weatherstripping. Summers regularly exceed 100°F here, and the UV chalks and embrittles vinyl over time. The weatherstripping at the sill and jamb dries out, the track gets gritty, and sliders start binding and leaking air long before the glass ever fails. We rebuild the track, swap the weatherstripping, and adjust the rollers where the frame allows it.
- Racked frames on settled pier-and-beam bungalows. The pre-1930 Craftsman and Spanish Colonial stock in Lincoln Park and near downtown Pomona sits on pier-and-beam foundations. When the sills settle, the rough opening twists. An ES replacement set into a racked opening stresses the frame corners and glass seals within a couple of seasons. We square and re-flash the opening before we ever set the window.
- Rot behind the frame from failed head flashing. Stucco cracking at the window head is routine after hot, dry Pomona summers. Once the head flashing fails, windblown rain and Santa Ana-driven debris get into the rough opening and rot the framing behind the window. We see this often on the post-WWII tract homes in Phillips Ranch and the northeast neighborhoods. The fix is never just a caulk line.
- Original ES single-pane units in 1950s-70s rear and patio openings. These horizontal sliders were built for a different era, and many are simply done. When the frame is cracked or the wall is moving, we tell the homeowner it’s time for a full replacement rather than another repair, and we quote the job honestly.
ES Windows Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona sits at the foot of the San Gabriel Mountains, and when the Santa Anas blow, they drive ember exposure into the older wood-frame neighborhoods in a way coastal-basin cities don’t experience. That’s the local fact that shapes how we glaze and flash ES windows on the pre-1930 stock around Lincoln Park and the Wilton Heights area. A window opening on a 1920s bungalow near downtown isn’t just a hole in the wall. It’s a fire entry point during a wind event, and it’s also sitting in a wall that has moved for a hundred years on a pier-and-beam foundation. We spec sealed units and flashing details with both realities in mind. The same applies to the post-war tract homes, which face their own version of the problem: 100°F heat cycling that bakes stucco, cracks head flashing, and accelerates vinyl frame fatigue. What we stock for a Pomona job is different from what we’d pull for Orange or North Tustin, because the failure pattern here is measured in UV hours and wind events, not salt air.
ES Windows Models & Products We Service in Pomona
We service the ES Windows units most common across Pomona’s housing eras: vinyl single-hung and slider replacement units, fixed and picture and awning combinations, vinyl horizontal sliders in 1950s-70s rear and patio openings, and single-hung retrofit inserts used in older double-hung openings. Our default is ES OEM replacement sashes, glass packs, and hardware where they’re available. When they aren’t, we use quality aftermarket sealed units, weatherstripping, and operators. We don’t force a full tear-out when a reglaze, hardware swap, and re-flash will hold for years. On cracked frames or failed seals in a wall that’s still moving, we’ll say so and quote the replacement honestly. For the full picture of our brand coverage, see our ES Windows sales & service page.

AfterES Windows Service Pricing in Pomona
What you pay depends on whether we’re repairing a sash, replacing a single unit, or re-flashing and re-setting multiple openings on a settled bungalow. Here’s the range we see most often on Pomona jobs:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
| Roof Replacement | $8,000 – $20,000 |
These are full-project ranges, not per-window unit prices. A Lincoln Park bungalow with three settled openings and rotted sills will land differently than a single slider swap in Phillips Ranch. Our free estimate includes access to the rough opening where we can get it, a line-item quote, and our honest read on whether repair or replacement makes sense. Call (844) 384-3361 to schedule yours.

FAQs – ES Windows Construction in Pomona
Usually yes. Most pre-1930 bungalows in Lincoln Park and the Wilton Heights area have rough openings that are no longer square or standard. We field-measure each opening and, where the rough opening has racked from pier-and-beam settlement, we square the framing before we ever order a unit. That often means custom sizing and always means custom flashing. Call (844) 384-3361 and we’ll measure it properly.
Yes. On the older wood-frame neighborhoods, we lean toward sealed units and glazing that hold up better under ember exposure, and we pay close attention to head flashing and sill pans. A coastal-basin home doesn’t face the same wind-driven ember pattern we see in the blocks around Lincoln Park and up toward the foothills. It changes the glass package and the flashing detail. Call (844) 384-3361 for a site-specific recommendation.
The short answer is heat and UV. Pomona’s over-100°F summers bake vinyl frames and break down the desiccant seal in older dual-pane units. Once the argon escapes and moisture gets in, you get fogging. The weatherstripping dries out at the sill and jamb, and the track binds. We see this pattern most on east and west elevations. Call (844) 384-3361 and we’ll tell you if it’s a reglaze or a replacement.
Sometimes. On one Lincoln Park bungalow off the older blocks near downtown, we opened the stucco around a fogged ES slider and found the original redwood sill dry-rotted and the rough opening out of square from decades of pier-and-beam settlement. We sistered new framing, re-flashed the head and sill, set a correctly sized ES replacement unit, and re-stuccoed. The new frame sealed tight and stopped both the draft and the fogging. That said, if the sill is fully compromised, sistering isn’t enough. We’ll tell you what we find when we open the wall. Call (844) 384-3361 for a free estimate.
