This page is for Los Angeles homeowners who bought ECO Window Systems windows and doors because they wanted something specific: a true divided lite on a Craftsman in Highland Park, a radius top on a mid-century in Los Feliz, a floor-to-ceiling fixed panel in Silver Lake. Those shapes are exactly what we work on. As an independent ECO Window Systems service provider, we are not affiliated with or authorized by the manufacturer, which means our recommendations are based on what the opening requires, not on warranty-department policy.

How ECO Window Systems Products Fail - and How We Fix Them

• Perimeter seal separation on geometric radius units. On ECO’s arch and half-round windows, the glazing bead and perimeter seal at the apex carry more thermal stress than anywhere else on the frame. In Los Angeles, the daily cycle of inland heat and coastal evening air pulls the seal away from the glass at the crown first. We see this on windows in Sherman Oaks and Studio City within six to eight years of install. The fix is a full deglaze at the affected section, new setting blocks, and a structural-grade silicone reseal, never a surface caulk bead over the old seal.
• IGU (insulated glass unit) fogging in fixed geometric panels. ECO Window Systems geometric fixed units often fail at the spacer bar when the original install didn’t account for drainage at the sill. Water sits, wicks into the seal, and the argon or krypton fill escapes. The glass fogs and you can’t wipe it clean because the moisture is inside the unit. We measure the exact sightline and order a replacement IGU matched to the original glass pack spec, including any low-e coating and tint, so the new pane doesn’t read different from the neighboring windows on the same wall.
• Hardware misalignment on operable arch-tops and shaped vents. ECO’s awning and casement-style shaped windows depend on a multi-point lock that has to engage in sequence. On a trapezoid or parallelogram vent in a stairwell, when the sash sags even 3/16 of an inch, the lock points miss the keepers and the window won’t seal. We reset the sash by adjusting the hinge cartridges, not by forcing the lock, which strips the gear teeth and turns a $180 adjustment into a $600 hardware replacement.
• Roller and track wear on oversized sliding doors. ECO Window Systems multi-panel sliders in Los Angeles homes get used hard, especially in hillside properties where the door opens onto a deck or pool. The weight of a 60-inch glass panel wears the nylon roller wheels flat after about seven to ten years of daily use, and the panel starts to drag or jump the track. We replace the carriage assemblies with load-rated rollers matched to the panel weight, then align the track so the door rolls on the bearing, not the frame.
• Warped frame corners on custom picture-window mulls. When someone installs a 10-foot-wide ECO picture window as a mull of three or four units, and the header above isn’t carrying the load properly, the outer frame corners twist. You’ll see the screen won’t seat or the operating vent starts to bind at the top corner. We don’t shim the sash to compensate. We pull the trim, measure the rough opening deflection, and correct the structural issue before resetting the frame. If we don’t fix the cause, the same corner fails again in three years.

What ECO Window Systems Custom & Geometric Windows Costs in Los Angeles

• Perimeter seal repair (single geometric unit): $340-$520. Includes deglaze, cleaning, setting blocks, and structural seal replacement.
• IGU replacement in a fixed arch or radius window: $480-$900 depending on glass area, low-e coating, and whether the unit is argon-filled.
• Hardware reset or hinge cartridge replacement: $180-$400 for a shaped operable vent.
• Full custom geometric window replacement (new frame, new glazing): $2,800-$7,500 depending on size, shape complexity, impact rating, and finish.
• Oversized slider roller and track service: $460-$800 for two to four panels, including load-rated replacement carriages and track alignment.

What moves the price is the glass pack: impact-rated glazing, low-e coatings, and custom tints add $180 to $400 per opening. The shape itself affects fabrication cost, not our labor; a true radius is no harder to set than a square if the rough opening is true. An exact quote requires a measured survey, and that survey is free. Call (509) 265-6387 for yours.
