A failing skylight shows up as fogging between panes, spider cracks, or the water stain creeping across your ceiling. GlassForge replaces skylight glass — laminated-over-tempered safety units built for overhead glazing — in curb-mount and deck-mount skylights from all major brands.
Few Philadelphia glass companies do overhead glazing; it requires laminated units, proper setting blocks and flashing knowledge. We inspect flashing and weep systems on every replacement so the fix actually holds.
