What we do
What does commercial window replacement involve?
What the work involves, and why it matters for your building.
What it is
Commercial window replacement is the removal and reinstallation of glazing across a commercial or multi-unit building, covering failed insulated glass units, storefront systems, and full-floor window packages. Glasscare manages measurement, sourcing, scheduling around occupied space, and compliant installation as a single source, so the building stays operational throughout the project.
Why it matters
A building-wide window project is a logistics job as much as a glazing job. The work has to be sequenced around tenants and access, the glass has to be sourced to match across the building, and the filings have to keep pace so nothing stalls. Doing it as a single source, one company owning measurement through installation, is what keeps the schedule intact and the building running. Glasscare handles the full project in-house, which is why property managers and GCs use it for capital and portfolio work.

Get the work done around your tenants, not despite them, with one point of contact for the whole building or portfolio.
General contractors
Drop glazing into your capital project on schedule, with a partner that hits the sequence and handles its own compliance.

FAQs
Frequently asked questions
How much does commercial window replacement cost?
+
Cost depends on the number of units, glass type, building access, and compliance requirements, so commercial projects are quoted per building rather than per window. Glasscare provides a free site assessment and a fixed quote after the visit. Call (201) 943-1122 to start.
How long does a commercial window replacement project take?
+
Timeline depends on unit count, glass lead time, and building access. After the site assessment, Glasscare gives a schedule with the sourcing window and the installation sequence built around your occupancy.
Can you replace windows in an occupied building without disrupting tenants?
+
Yes. Most commercial window replacement Glasscare handles is in occupied buildings. Work is sequenced around tenants and building access, often floor by floor or unit by unit, so the property stays operational.
Do you handle NYC DOB and NJ DCA filings?
+
Yes. Glasscare is NYC DOB compliant and NJ DCA compliant, and filings are managed as part of the project, so you do not coordinate a separate filing process.
What types of commercial windows do you replace?
+
Glasscare replaces insulated glass units, double pane and fogged units, tempered and laminated glass, storefront glazing, and full window systems. Where the frame is sound and only the glass has failed, Glasscare replaces the IGU rather than the whole window.
