ES Windows Kitchen Remodeling: The Pomona Owner’s Guide
ES Windows kitchen remodeling in Pomona typically runs $14,000-$45,000 for a full replacement with compatible framing, finish carpentry, and sealant work included. We stock ES Windows-compatible hardware and trim packages for same-day starts on most standard openings, and we measure every rough opening on-site before ordering - no surprises when the unit arrives. Most Pomona homeowners discover their ES Windows kitchen installation needs attention when they notice drafts around the frame, condensation between panes, or the sash no longer seats square against the weatherstrip after years of thermal cycling in the Inland Empire sun.
Which ES Windows Models This Applies To
ES Windows manufactures impact-resistant and non-impact vinyl and aluminum window systems, and their kitchen applications in Pomona homes typically fall into the ES 100 Series (non-impact vinyl single-hung), ES 5000 Series (impact aluminum single-hung), and the ES 8000 Series (impact aluminum horizontal roller). The critical compatibility point is the frame depth: ES 100 Series uses a 2-5/8-inch frame, while the 5000 and 8000 Series run 3-1/4 inches, which affects how the window sits in a kitchen’s plaster or drywall return without chewing into countertop backsplash space.
To identify your unit, check the etched mark in the glass corner or the label on the frame head - it’ll read “ES” followed by the series digits and a date code. We carry OEM-grade balances, sash locks, and weatherstrip for all three series, plus aftermarket heavy-duty rollers for the 8000 horizontal rollers that outlast the factory spec in Pomona’s dust-heavy environment near the 10 and 60 freeways. Measure twice, then we can talk.
Signs Your ES Windows Kitchen Remodeling Is Failing

- Visible condensation or fog between glass panes. The insulated glass unit (IGU) seal has failed, allowing moist Inland Empire air into the cavity. In Pomona’s dry summers this often goes unnoticed until winter, when the temperature delta between kitchen and exterior forces the moisture visible.
- Sash drags, sticks, or won’t stay open. The balance system - the spring-loaded mechanism that counterweights the sash - has fatigued. ES 100 Series vinyl units use a constant-force coil balance that loses tension after roughly 12-15 years of daily kitchen use.
- Draft at the frame perimeter even when closed and locked. The compression weatherstrip has hardened or the sash lock no longer pulls the sash tight against the frame. Pomona’s UV exposure accelerates this; we see it first on south- and west-facing kitchen windows.
- Water staining on the sill or drywall below. The weep holes are clogged with debris, or the sill dam (the raised ridge on the frame bottom) has been caulked over by a previous handyman, trapping water inside the frame to rot the sub-sill.
- Frame corners gaping or sealant cracking. Thermal expansion has stressed the mechanical corners of aluminum frames, or the vinyl has welded-seam separation. This is structural - the window will leak air and water until the frame or entire unit is addressed.

The wide range on full kitchen jobs reflects cabinet proximity, countertop material (quartz or granite backsplashes require delicate cutting), and whether stucco or siding repair follows the install. Every quote we deliver in Pomona is a flat written price with line-item scope - under Clause 1 of The Haven Standard, the number is fixed before anyone picks up a tool. Our 365-Day Done Right Promise covers the installation and hardware; IGU seal failure is backed by the manufacturer’s warranty, which we register and document in your photo record.
DIY or Call Us?

An owner can safely check the weep holes for debris, verify the lock engages fully, and confirm the weatherstrip is present and pliable - these three checks solve about 20% of the calls we get. Beyond that, ES Windows units, particularly the impact-rated 5000 and 8000 Series, weigh 40-70 pounds per sash and require proper shimming, fastening, and sealant application to maintain their structural rating. Improper installation voids the impact certification, which matters for resale and insurance in Pomona’s wind zone.
We do not recommend homeowner removal of IGUs or balance systems - the glass is tempered but heavy, and the coil balances store enough energy to cause hand or facial injury if released uncontrolled.

FAQs
Expect 15-25 years for vinyl frames and 20-30 years for aluminum, though IGUs often fail at 12-18 years due to seal degradation in the Inland Empire’s temperature swings. Call (626) 606-1081 for an exact quote on replacement - estimates are free.
The IGU itself cannot be repaired - once the seal fails, the glass assembly must be replaced. The frame can often be retained if it’s structurally sound, which cuts cost significantly versus full unit replacement. Call (626) 606-1081 for an exact quote - estimates are free.
A single unit replacement takes 2-4 hours; a full kitchen with 3-4 openings is usually a 1-2 day job including trim and sealant cure time. We protect countertops and flooring as standard, and you’ll receive a documented photo record of the rough opening condition and finished install. Call (626) 606-1081 to schedule.
We stock balances, locks, rollers, and weatherstrip for the 100, 5000, and 8000 Series on our Pomona trucks. Full frame or IGU replacements are ordered to measured size, typically 2-3 weeks for non-impact and 4-6 weeks for impact-rated custom units. Call (626) 606-1081 to confirm current availability for your series.
