What we do
What does new window installation involve?
What the work involves, and why it matters for your building.
What it is
New window installation is the fitting of brand new window units into new or renovated openings, as opposed to replacing failed glass in existing frames. Glasscare installs new windows across commercial and multi-unit projects in NJ and NYC, including units the client has already purchased.
Why it matters
On a large project, the windows are sometimes already bought, and what is needed is a crew to install them correctly, on schedule, and to code. Glasscare can supply and install, or install client-supplied windows, with measurement, logistics, and compliant fitting handled in-house. If you have windows and need an installer for a big project, that is squarely the work Glasscare does.
