Questions
Window Repair FAQs
My double-pane window is foggy — can you fix it?
Yes — we replace the insulated glass unit (IGU) in the existing frame, much cheaper than a full window.
Can you repair a window that won't stay open?
Yes — almost always a broken sash balance. Standard repair across Nassau and Queens.
Do you re-screen window screens?
Yes — full re-screen with fiberglass or aluminum mesh in our shop, typically 2–3 day turn.
