Failed seals and loose sash alignment leak conditioned air and street noise through gaps you stop noticing until guests mention the chill near the sill.
Uneven stacks cause baffling pockets where winter cold anchors beside the latch.
Interior condensation between panes signals seal failure — aesthetics tank alongside clarity.
Thin glazing assemblies struggle against garbage trucks and traffic peaks.
Northstone crews photograph openings, verify square, and confirm egress expectations before fabrication queues unlock — reducing punch-list rework after trim goes back up.
