Island Glass Company diagnoses and repairs failing windows for homes and commercial buildings across Whittier and the surrounding Southern California cities. Many windows that feel “past the point of replacement” can actually be brought back to life with the right parts — and when they cannot, we will say so plainly.
What we repair
- Foggy dual-pane units — replacing the failed IGU while keeping the original frame and sash
- Broken seals and condensation between panes — usually caused by a failed spacer, a cracked exterior glaze, or a broken perimeter seal
- Stuck or crooked sliders — rollers, tracks, and lock mechanisms
- Double-hung balances and sash cords — replacing spring balances, block-and-tackle systems, or counterweights on older windows
- Casement and awning operators — cranks, hinges, and worm gears
- Weatherstripping and seals — compression seals, fin seals, and parting beads
- Locks, latches, and handles — replacing cam locks, sash locks, and multi-point lock systems
- Failed vinyl welds — on older uPVC frames where a corner has split
Diagnosis-first approach
We walk every repair with the homeowner or facility manager and show exactly what is wrong. If the frame itself has rotted out, the vinyl has cracked beyond repair, or the structural seal has failed across every window on a wall, we will recommend replacement and price both options side by side. No pressure, no upselling — just the real answer.
Common fixes at a glance
- Drafts around the sash: usually weatherstripping, sometimes a warped sash
- Window will not stay up: balance failure on a double-hung
- Water on the sill: failed exterior seal or a clogged weep hole
- Cloudy or hazy glass between panes: failed IGU, replace the glass unit
- Cranking but not closing: worn operator mechanism in a casement
