ES Windows Windows & Doors Nationwide

ES Windows Windows & Doors: The Los Angeles Owner’s Guide

We stock and install ES Windows-compatible windows and doors across Los Angeles, with most replacement projects in the $5,310-$17,700 range depending on frame material, glass package, and whether the opening needs reframing. Most standard-size units are available within 2-3 business days; custom ES Windows orders typically run 3-4 weeks from measurement to install. Los Angeles homeowners usually discover a problem when the sash won’t stay open, the lock no longer catches, or they feel a draft along the sill during Santa Ana wind events that wasn’t there in spring.

Which ES Windows Models This Applies To

ES Windows manufactures impact-resistant and non-impact vinyl and aluminum windows primarily for the Florida and Caribbean markets, but their products have been installed in Los Angeles since the mid-2010s, particularly in Marina del Rey, Playa Vista, and the beach cities where homeowners wanted hurricane-rated units for salt-air corrosion resistance. The most common ES Windows series we service in Los Angeles are the ES 100 Series (single-hung vinyl), ES 200 Series (horizontal roller), and ES 5000 Series (impact-rated aluminum).

To identify your unit, open the sash and look for the etched manufacturing label in the glass corner or the stamped aluminum rating label on the frame edge. You’ll need the NFRC rating number and the series designation, not just the rough opening size. The ES 5000 Series uses a proprietary interlock system that does not interchange with standard aftermarket replacement parts; for these, we source factory-equivalent components through our distributor network rather than generic hardware that will fail to seal properly. For the ES 100 and 200 series, quality aftermarket balances, locks, and weatherstripping are available and perform equivalently at lower cost.

Signs Your ES Windows Windows & Doors Is Failing

• Sash drops or won’t stay open. The coil balance system has lost tension, which happens faster in Los Angeles than in cooler climates because vinyl frame expansion from summer heat cycles fatigues the balance spring. On ES 100 Series single-hung units, we see this most often in west-facing windows after six to eight years.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed, allowing argon gas escape and condensation. In coastal Los Angeles neighborhoods like Venice and San Pedro, salt air accelerates seal degradation; ES Windows IGUs typically show this at 10-14 years versus 15-20 inland.
• Lock tongue won’t extend or retract fully. The multipoint lock mechanism has corroded or the keep has shifted due to frame settlement. ES 5000 Series impact locks are particularly sensitive to even minor frame racking because the interlock must engage across three points simultaneously.
• Draft at the sill or jamb even when closed. Compression weatherstripping has flattened or the sill track has worn to the point that the sash no longer seats fully. In Los Angeles, UV exposure degrades the bulb-style weatherstrip on south-facing units faster than the manufacturer rating assumes.
• Excessive noise transmission or visible frame distortion. The window is approaching end of service life; aluminum frames in the ES 5000 Series can develop stress cracks at the corner joints after repeated thermal cycling, and once a corner separates, the unit cannot be field-repaired to original structural rating.

Replacement Cost & What’s Included

Window replacement in Los Angeles runs $5,310-$17,700 for standard residential units, with the range driven by three factors: frame material (vinyl at the lower end, thermally broken aluminum or impact-rated at the upper), glass package (dual-pane standard versus triple-pane or laminated impact), and whether the existing rough opening is square and structurally sound. ES Windows units fall across this full spectrum depending on series and specification.

Our quotes are flat prices with written scope, delivered before any work starts. The price includes removal and disposal of the existing unit, installation of the replacement with proper sill pan flashing and backer rod sealant, interior and exterior trim repair or replacement as needed, and cleanup. We pull permits when required by Los Angeles building code, which applies to any replacement that changes the egress characteristics or structural opening. Every installation carries our 365-Day Done Right Promise: if it’s not done right, we make it right. The Haven Standard requires it.

You’ll receive a documented photo record of the opening condition, the installed unit, and the sealant detail before we invoice. If it’s not written down, it didn’t happen.

DIY or Call Us?

An owner can safely check a few things: verify the lock is fully engaged, clean debris from the sill track, and confirm the weep holes at the frame bottom are unobstructed so water drains out rather than in. These are maintenance items, not repairs.

Where DIY goes wrong with ES Windows units specifically: the coil balance replacement on single-hung units requires a tensioning tool and knowledge of the proper weight calibration, and an overtensioned balance can shatter the pivot bar or cause the sash to slam shut unexpectedly. The ES 5000 Series impact interlock demands precise shimming to maintain the design pressure rating; a homeowner installation that looks correct may fail to perform in a seismic event or high wind. We don’t recommend homeowner removal of any window in a stucco or EIFS wall, as the waterproofing integration at the sill is unforgiving and latent water damage is expensive to remediate.
