ES Windows Construction in Pomona, CA | Square Deal Contractors
We provide independent ES Windows replacement and retrofit service across Pomona, from 91768 down through 91766. The thing that makes our ES Windows work here different is simple: we know how these units fail on Pomona’s older stock, and we know what Pomona’s building department is going to ask when you touch a window that’s tied to an unpermitted conversion. Call (866) 623-7205 for a free estimate on any ES Windows repair or replacement.
Square Deal Contractors handles ES Windows construction work across every Pomona ZIP code, from single-hung vinyl replacements on original 1940s bungalows to sliding door swaps on postwar tract homes. We’re a full-scope general contractor, not a window-only shop, which means when an ES Windows job uncovers framing, flashing, or stucco problems behind the trim, we fix those too, under one contract.
Why Pomona Residents Choose Us for ES Windows Service
We’ve been doing ES Windows replacement and retrofit work across Pomona’s single-story Craftsman and Spanish-revival bungalows for years, and that matters because these houses don’t behave like newer builds. The openings are rarely square. The framing is often original. And a surprising number of windows were installed in conversions that never saw a building inspector. None of that surprises us. We plan for it from the first measurement.
Nolan Breckett, our owner, grew up in South Orange County and came up through Saddleback College’s construction technology program, where the coursework was hands-on, not theoretical. He’s spent the better part of three decades fixing the kind of framing and flashing decisions that cause problems twenty years later. That background is exactly what Pomona’s older housing stock demands. We’re an independent contractor, not affiliated with, authorized by, or sponsored by ES Windows. That independence means we recommend what’s actually right for your opening and your budget, not what a manufacturer program requires us to push.
When you call us, you get a straight answer about whether that fogged sash or sticky slider is worth repairing or whether the whole unit has hit the end of its useful life. We source ES-compatible OEM or quality aftermarket sash, glass, and hardware where it makes sense. If the frame is distorted and the opening is compromised, full replacement is usually the honest call. We’ll tell you which, and why.

Common ES Windows Construction Problems We Solve in Pomona
- Sticking sashes and failed latches on west- and south-facing walls. Pomona summers routinely hit 95 – 105°F, and that heat lands hardest on the afternoon exposure. Vinyl frames and sashes soften, then cool unevenly overnight. Over a few seasons, the sash distorts just enough that it refuses to seat or latch. We see this constantly on stucco bungalows with original thin-wall extrusions. The fix is usually new sash and hardware, unless the frame itself has warped, at which point a replacement unit is cheaper than fighting the old one.
- Dried-out and compressed weatherstripping and sweep seals. Southern California’s long dry season bakes rubber and felt seals until they crack, shrink, or fall out altogether. On Pomona’s older homes, that means dust gets in and cooled air leaks out, which pushes up cooling loads through August and September. We replace these seals with current-generation materials that tolerate inland heat better than the originals ever did.
- Fogged dual-pane insulated glass units. This is the call that starts more ES Windows jobs in Pomona than any other. The seal between panes fails, condensation builds inside, and the glass turns milky. On older ES units it’s common, and it’s often cheaper to replace the sealed unit than to live with a window you can’t see through. If the frame is sound, we do the glass only.
- Water intrusion at the sill from poorly flashed or caulked openings. Pomona has a significant share of converted garages and back-room additions that were never permitted, and a lot of those windows were set without header support or proper flashing. Leaks show up at the sill, not the glass. When that’s the case, we rebuild and flash the opening correctly before setting the new ES unit, and we pull the work through Pomona’s plan check.
- Home addition and room conversion window packages. When homeowners add square footage to a Pomona bungalow or legalize an unpermitted back room, we spec ES vinyl sliders and single-hungs across the new openings. We match frame profiles to the existing house where it matters, and we handle the permit side so the inspection passes the first time.
ES Windows Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona runs its own building department and a large share of the city’s older lots carry unpermitted garage-to-living-space and back-room conversions, so an ES Windows replacement that touches those converted openings can trigger plan check and inspection that a same-sized swap on a permitted wall would never require. That’s not a generic Los Angeles County problem. In Pomona, the housing stock is older and more densely converted than in surrounding foothill communities, and code enforcement attention is real. The practical effect for an ES Windows owner is this: you might plan to swap two sliders and end up needing framing correction, header installation, and an inspected opening before the new windows go in. We plan for that from the first site visit rather than discovering it during tear-out.
On a Spanish-revival bungalow off the 91767 side of town, we were called about fogged ES vinyl sliders in a converted back room. During tear-out we found the opening had no header, no flashing, and no permit history because the conversion was done quietly years ago. We pulled the scope into Pomona’s plan check, rebuilt and flashed the opening properly, and set new ES replacement sliders spec’d for the west-facing exposure. The room stopped leaking and overheating, and the homeowner finally had a permitted, inspected window on a permitted wall. That’s the difference between a window installer and a contractor who understands Pomona’s built environment.
ES Windows Models & Products We Service in Pomona
We work on the full range of ES Windows product lines you’re likely to find in Pomona, including vinyl single-hung replacement windows, sliding glass doors and patio sliders, vinyl horizontal sliders common in converted garages and additions, and fixed or picture window units with vinyl frames. If your glass is fogged, your sash is binding, or your patio door won’t track, we diagnose the specific failure and compare repair cost against replacement before recommending anything.
Because Pomona’s housing stock is older and ES units from different eras turn up side by side on the same house, we keep a practical inventory of common sash, glass pack, and hardware parts local to the Inland Valley so turnaround on straightforward repairs is measured in days, not weeks. For ES Windows sales & service, we spec current-generation units for the exposure and opening conditions, not a generic size from a catalog.
The ES Windows sales & service work we do stretches well beyond window swaps, and Pomona’s older bungalows regularly demand full-scope attention, which fits how we operate as a general contractor. You’re not coordinating a window crew, a framing crew, and a stucco patch separately. We handle it under one contract.

AfterES Windows Service Pricing in Pomona
Pricing on ES Windows work in Pomona depends on what the opening actually needs once we look behind the trim. A straight glass-pack replacement on a sound frame costs far less than a full replacement on a converted opening that needs header and flashing work. Here are the ranges we work within for Pomona projects:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
Window replacement pricing reflects the number of units, whether the openings need structural correction, and whether the existing frames are worth keeping. Impact-rated glass costs more, and we’ll tell you plainly when it’s worth the spend and when it isn’t. Every estimate is written, line-itemed, and scoped to what we found on site, not a square-foot multiplier. Call (866) 623-7205 to schedule a free estimate, and we’ll tell you exactly what you’re getting and why.

FAQs – ES Windows Construction in Pomona
Yes, and this is the single biggest surprise for Pomona homeowners. If the original conversion was never permitted, the window opening itself may not be legal, which means a straightforward swap can turn into a plan-check item. We handle the permit and inspection work as part of the scope, and we’ll flag the issue before any work starts. Call (866) 623-7205 and we’ll tell you whether your specific opening is likely to trigger Pomona’s permit review.
Yes, and the mechanism is heat, not age. Vinyl frames and sashes expand during 95 – 105°F afternoon exposure, then contract overnight. Repeat that across several summers and the sash can distort enough to stick or fail to latch, especially on older thin-wall extrusions. We see it most often on unshaded west-facing walls and on south-facing picture-window spans. Replacement units with current-generation vinyl formulations tolerate the cycling better, and proper flashing and sealing matter as much as the extrusion.
Yes. We field-measure every opening, and on older Pomona homes the openings are rarely square or consistent from room to room. We spec unit sizes and frame profiles to fit the actual rough opening, not a nominal size, and we adjust trim and reveal details so the new window sits correctly in walls that have settled over seventy or eighty years. Where the framing is compromised, we correct that first, because a new window in a bad opening will leak and bind regardless of what you paid for the glass.
Not by code in most of Pomona, but if you’re near the city’s foothill edges and wildfire hardening matters to you, impact-rated and dual-glazed units with tempered glass are worth considering. They add cost, and we’ll give you a straight read on whether the spend makes sense for your specific street and exposure rather than upselling everyone toward the highest-tier glass.
We are an independent contractor, not affiliated with, authorized by, or sponsored by ES Windows, so we don’t process manufacturer warranty claims on their behalf. We can document the failure, provide the site evidence you need to file a claim, and complete the repair or replacement work with OEM-compatible parts. If a warranty credit comes through, we’ll factor it into the final scope. Call (866) 623-7205 for a straight answer on what your specific issue is going to cost.
