ES Windows Construction in Pomona, CA | Mason Remodeling Co West Covina
We provide independent ES Windows service and construction across Pomona, from full replacements to targeted repairs on 9600 Series casements, Estate Series sashes, and 7600 Series sliding doors. What makes our work here different is simple: over a decade of tear-outs and retrofits on Pomona’s pre-1940 Craftsman and Spanish Colonial Revival homes has taught us exactly how clay soil, Santa Ana winds, and unreinforced masonry interact with these specific window frames. That’s knowledge a factory manual can’t give you. Call (707) 760-7579 for a free estimate on any ES Windows project in Pomona.
Why Pomona Residents Choose Us for ES Windows Service
We learned ES Windows the way you learn anything worth knowing: by taking them apart. Isaac Pruett, our owner, came up through the construction technology program at Los Angeles Trade-Technical College and spent years on San Gabriel Valley jobsites before Mason Remodeling took shape. When he and the crew pull an ES window out of a 1920s Pomona wall, they know what the original installer did right and what they did wrong. That matters when you’re deciding between a $400 repair and a $12,000 replacement. We’re independent, which means we recommend what the window actually needs, not what a factory program tells us to sell. If the frame is sound, we repair it. If it’s sun-baked and failing in three places, we’ll tell you that too, and show you the numbers side by side.

Common ES Windows Construction Problems We Solve in Pomona
These are the failure patterns we see repeatedly across Pomona, tied directly to local conditions:
- Thermal seal failure on southwest-facing glass. Pomona’s afternoon sun is relentless, and windows facing it take the worst of it. We regularly replace fogged or condensation-filled insulated glass units on ES Windows 9600 and Estate Series units where the seal has degraded after years of thermal cycling. In Lincoln Park and Wilton Heights, older homes with original 1990s installs show this first.
- Sticking sashes and twisted frames from expansive clay soil. Pomona’s soil moves. When foundations shift through wet winters and dry summers, window frames rack. Older ES 9600 models with wood or aluminum sashes bind at the corners. Sometimes a realignment and hardware replacement solves it. Sometimes the rough opening itself needs rebuilding so the frame sits square again.
- Failed sash locks and keepers on Estate Series windows. Santa Ana winds hit Pomona hard, and windows on the windward side take repeated buffeting. The lock hardware on Estate Series sashes loosens, strips, or bends. We replace these with OEM parts when the hardware is warranty-sensitive, and with upgraded aftermarket hardware when the factory spec keeps failing in the same wind conditions.
- Sliding door rollers on ES 7600 Series doors. Pomona patios settle, and tracks collect fine grit from dry inland air. The result is a 7600 Series door that takes a shoulder to move. We replace bent or broken rollers, clean and realign the track, and if the door’s been fighting you for years, we’ll tell you whether it’s a roller job or a full replacement.
- Rot at sill corners from missing weep holes. This one shows up most often in Pomona’s older homes, where original ES window installs predated current flashing and drainage standards. Condensation with nowhere to go rots wood sills from the inside out. We rebuild the rough opening with pressure-treated lumber and flash it to current Pomona code before reinstalling the window.
ES Windows Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona’s Unreinforced Masonry Ordinance requires seismic retrofits on many pre-1940 homes, and those retrofit projects reveal something important about the city’s older building stock. During retrofits in neighborhoods like Lincoln Park and Wilton Heights, we routinely find ES Windows frames that were set directly into brick without proper flashing. The installers counted on the stucco or trim to shed water, and for a while it worked. But decades of Pomona’s wet winters and dry summers have opened hairline gaps, letting moisture behind the frames. That’s not a manufacturing defect. It’s an installation detail specific to Pomona’s balloon-framed and masonry homes, and it’s exactly the kind of thing we look for before recommending any ES Windows repair or replacement. A newer tract home in a neighboring city won’t have this problem. A 1928 Craftsman in Pomona very well might.
ES Windows Models & Products We Service in Pomona
Our ES Windows sales & service experience covers the three lines most common in Pomona homes: the 9600 Series, the Estate Series, and the 7600 Series sliding glass door. We also stock high-turnover parts locally so a thermal sash replacement or roller repair doesn’t wait on a factory shipment. For warranty-sensitive components like sashes and lock hardware, we use OEM ES Windows parts when they’re available. For seals, rollers, and screens, we often install aftermarket parts that match or exceed factory spec and hold up better under Pomona’s sun and grit. We’ll show you the part, explain why we chose it, and put it in writing. When we’re on an install or repair job that calls for it, we also handle window replacement work and impact window installation, along with roof repair where window and roofline flashing meet.

What drives the cost on ES Windows work in Pomona is mostly the condition of the rough opening. A clean swap on a 1960s ranch with intact framing is straightforward. A 1920s balloon-framed wall with rotted sills and no flashing is a different job altogether, and it should be priced accordingly. Our free estimates include a written line-item quote before any work starts, so you’ll know exactly what’s included. No verbal numbers that grow on the final bill.

FAQs – ES Windows Construction in Pomona
Do you handle ES Windows replacements in Pomona’s historic districts like Lincoln Park?
Yes, and we’ve done many. Homes in Lincoln Park and Wilton Heights fall under Pomona’s preservation review process, which means window replacements often need to match the original sightlines and materials. We’ve navigated that process before and can help you prepare the documentation the city needs. Call (707) 760-7579 and we’ll talk through what your specific house requires.
Can you repair just the glass in my ES Windows 9600 instead of replacing the whole unit?
In most cases, yes. If the frame and sash are sound and the problem is a failed thermal seal or cracked glass, we can replace the insulated glass unit without pulling the whole window. That typically runs far less than a full replacement. If the frame is racked from soil movement or the sill is rotted, we’ll show you the damage and give you a repair number and a replacement number side by side. Estimates are free.
My ES Windows sliding door (7600 series) is very hard to open. Is that a track or roller problem?
Usually it’s both. Pomona’s dry air means fine grit accumulates in the track, and patio settlement throws the rollers out of alignment. We start by cleaning and realigning the track, then inspect the rollers. If they’re bent or worn, we replace them, often with aftermarket rollers that handle grit better than the originals. Call (707) 760-7579 for an exact diagnosis and quote.
Will replacing my old ES Windows with new ones help with Pomona’s summer heat and Santa Ana wind noise?
Yes, and the difference is measurable. Modern ES Windows thermal sashes with intact seals block significantly more heat transfer than 30-year-old units with failed seals. For wind noise, a properly flashed and sealed installation makes the biggest difference, especially on windward walls. We also recommend impact-rated glass on elevations that take the full force of Santa Ana gusts.
What do you do with the old ES Windows you remove during a remodel?
We haul them away and handle disposal or recycling, depending on the materials. Glass, aluminum, and wood are separated where possible. You won’t be left with a pile of old sashes on the driveway. If you’re planning a remodel in Pomona and replacing multiple windows, we’ll include removal and disposal in your written quote.
