Storm Window Repair in NJ and NYC for Older and Multi-Unit Buildings
Storm windows protect the primary glazing and add insulation, and when they crack or the frame fails they stop doing both. Glasscare repairs storm window glass and frames across older and multi-unit buildings in northern NJ and NYC.

What we do
What is a storm window and what does repair involve?
What the work involves, and why it matters for your building.
What it is
A storm window is a secondary window mounted over the primary one to add insulation and protect against weather, common on older buildings. Repair covers cracked glass, damaged frames, and failed weatherproofing. Glasscare assesses the unit, replaces glass, and repairs frames across older and multi-unit buildings in northern NJ and NYC.

Why it matters
Storm windows take the brunt of the weather so the primary window does not, which is exactly why they crack, bind, and lose their seal over time. A cracked pane or a failed seal stops the storm window doing its job, and on an older building full replacement is not always the answer. Often the glass is replaced or the frame repaired and the existing unit kept. Glasscare assesses whether a repair or a replacement makes sense, and handles the work across a building on one schedule.

What Our Clients Say
FAQs
Frequently asked questions
What does a storm window do?
+
It adds a layer of insulation and weather protection over the primary window, reducing drafts and protecting the main glazing. When it is damaged, both of those benefits drop off.
Repair or replace a storm window?
+
Minor glass and frame damage is repaired, which keeps the existing unit. If the unit is beyond repair, Glasscare advises replacement and can install new storm windows. The assessment confirms which is practical.
Do you handle storm windows on older buildings?
+
Yes. Storm window work is common on older buildings, and Glasscare repairs and matches existing units across a property.
Can you repair storm windows across multiple units?
+

How much does storm window repair cost?
+
Cost is quoted per window based on the repair. Call (201) 943-1122.
