ES Windows Construction in Pomona, CA | Iron Beam Contractors
We provide independent ES Windows service across Pomona, from full window replacement to glazing, hardware, and sill repair on existing units. We’re not a manufacturer-authorized dealer, and we don’t pretend to be. What we are is a general contractor that has pulled, re-glazed, and re-installed enough ES Windows in Pomona’s 1900s bungalows and newer ADU builds to know exactly how their aluminum frames and seals behave under this city’s inland heat. Call (833) 756-5936 and tell us what your windows are doing. We’ll tell you what’s actually wrong.
Why Pomona Residents Choose Us for ES Windows Service
Nolan Driscoll built Iron Beam Contractors on a plain rule: tell the homeowner what’s in the wall before you open it. That matters with ES Windows, because what’s behind the trim on a 1920s Pomona bungalow is rarely what the original framing looked like. We’ve replaced sills on Garey Avenue homes where the weep tracks were packed with sixty years of citrus-belt dust, and re-glazed ES sliders on Holt-adjacent rentals where the gaskets had shrunk to brittle ribbons, with similar work handled through our ES Windows service in Claremont. We know these windows because we’ve taken them apart, not because we read a catalog.
We also carry the parts that generic window companies won’t bother with. OEM ES Windows rollers, weatherstrip, and glazing gaskets where the profiles are still active, and a vetted matching aftermarket line when a discontinued ES extrusion forces it. That’s the difference between a fifteen-minute hardware swap and a pointless full replacement. Pomona homeowners call us because somebody told them they needed all-new windows, and it turned out they needed two rollers and a latch.
We’re an independent contractor working on ES Windows because we know them, not because the manufacturer endorses us. That independence is the point. It means we’ll tell you when a repair is honest money and when you’re better off replacing the unit.

Common ES Windows Construction Problems We Solve in Pomona
- Sticking or sagging ES vinyl sliders. Pomona’s daily-use sliding windows see a lot of cycles, and the rollers on ES horizontal sliders wear flat within a decade. The sash drops, scrapes the track, and won’t latch. Usually it’s two rollers and a track clean, not a new window. We stock the roller sets so we can swap them without waiting on a parts drop.
- Fogged dual-pane glass on ES fixed and picture units. Seal failure shows up as haze between the panes after enough high-heat façade exposure. This is common on rear addition windows that face the afternoon sun through a Pomona summer. We price IGU replacement against full unit replacement and recommend the cheaper honest fix when the frame is still sound.
- Water ponding and corrosion at the sill. ES aluminum sliders have weep holes and track drains that clog with the fine dust this valley produces every summer. When the drains plug, water sits in the track and the sill starts to pit. On older 91766 and 91767 bungalows we see this often enough that we check the drains first, before we blame the window.
- Drafty gaskets and sealant shrinkage. Thermal cycling from Pomona’s 95°F-plus inland summers shrinks sealant and glazing gaskets on ES aluminum frames. You’ll feel it as a draft near the sash, and you’ll see it as dust collecting along the track. Fresh gaskets and a re-glaze usually fix it without touching the frame.
- Hard-to-lock sashes on ES hinged and multi-slide patio doors. Latches wear, strikes drift out of alignment, and doors that bound shut in winter refuse to lock in summer. It’s a hardware and alignment problem, not a structural one. We correct it at the hinge and the strike, then test the throw.
ES Windows Service in Pomona: What Local Conditions Mean for Your Equipment
On Pomona’s deep alley-access lots in 91766 and 91767, rear ADU and addition walls often land where no truck can reach. That’s not an inconvenience; it’s the deciding factor in how a window job gets sequenced. A concrete truck can’t squeeze down a 10-foot alley behind a 1920s bungalow, and neither can the delivery truck carrying your ES Windows frames. So we hand-stage every unit down the alley before the opening is framed, and we sequence the glazing so the fixed and slider units go in the same day the flashing does. If you’ve ever watched a crew try to wheel a 6-foot window down a gravel alley on a dolly, you know why that sequencing matters. We plan for it from the first site walk. It changes how we schedule ES Windows deliveries, where we set the saw horses, and when we pull the old frames, the same approach we take for Los Serranos ES Windows service. In Pomona, the alley is part of the job. Any contractor who ignores it is pricing a different city.
ES Windows Models & Products We Service in Pomona
We work on ES Windows Series 200 aluminum sliding windows, the vinyl single-hung and horizontal slider lines, fixed and picture units used in rear additions and ADU walls, and the multi-slide and hinged patio door units. Parts approach is straightforward: OEM ES Windows rollers, weatherstrip, weep covers, and glazing gaskets where the profiles are still supplied, and a matching quality aftermarket line when a discontinued ES extrusion forces it. We keep the common Pomona wear items on hand, so a sagging slider in a 91768 tract home doesn’t wait a week on a parts order from the East Coast. For fogged units, we price the IGU and hardware repair honestly against full replacement. Repair wins when the frame is sound. Replacement wins when the frame is pitted or the wall opening is being reworked anyway.

AfterES Windows Service Pricing in Pomona
Pomona window work prices land where the scope actually is. A double-hung swap on a 1950s east-side tract home runs different money than re-glazing a wall of fixed ES picture units on a rear addition. Here’s the range:
| Scope | Typical Pomona Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
What drives the number: frame condition, how many units need re-glazing versus full replacement, whether the wall opening is being reworked for an ADU or addition, and whether the alley access means hand-staging instead of a delivery truck. Our estimates are written line items, not a round number on a napkin. Call (833) 756-5936 and we’ll price your actual windows, not a county average.

FAQs – ES Windows Construction in Pomona
Yes, and we do it regularly. We pull the existing sliders, assess the frames, and set new ES slider and fixed units with fresh flashing and sealant so the rear wall reads as original from the street. The hard part is the alley staging, which we handle. Call (833) 756-5936 for a site walk.
That haze is a failed dual-pane seal, and Pomona’s high-heat façade exposure accelerates it. The fix is an IGU replacement when the frame is sound, or a full unit replacement when the frame is pitted or the opening is being reworked. We price both so you can decide on numbers, not a guess.
More often than not, it’s a repair. Worn rollers, a clogged track, or a drifted strike plate. We replace the rollers and weatherstrip, clean the track, and test the lock throw. If the frame is pitted or the sash is out of square, replacement becomes the honest call. Call (833) 756-5936 and we’ll tell you which one it is.
It makes staging the deciding step. No delivery truck gets back there, so we hand-carry each ES Windows unit down the alley before framing. It adds labor and planning, but it’s the only way to do the job right. We sequence around it from the first site visit.
If your home sits near the northern foothill edges where wildfire-conscious materials matter, impact-rated glass is a defensible upgrade. It costs more, but the combination of Santa Ana wind debris and ember exposure makes it functional, not decorative. Call (833) 756-5936 for an exact quote. Estimates are free.
