What we do
What does sliding glass door replacement involve?
What the work involves, and why it matters for your building.
What it is
Sliding glass door replacement covers either the full door unit or the glass panels, for patio and balcony doors that are damaged, failed, or beyond repair. Glasscare assesses the door, measures, and installs a new unit or tempered glass panels to code across multi-unit and residential properties in northern NJ and NYC.
Why it matters
There is a line between repair and replacement. A door with worn rollers and sound glass is repaired, but a door with a failed frame, broken track system, or damaged glass that is no longer cost-effective to fix is replaced. When only the glass has failed and the frame is sound, Glasscare replaces the panels. When the unit itself has failed, the full door goes in. The assessment confirms which makes sense, and either way the glass is tempered safety glass by code.
