Do You Know When to Replace Your Windows?
If your windows feel drafty, stick when opening, or allow outside noise inside, it may be time for replacement. Older windows can cause higher energy bills and reduce comfort during Long Island winters and humid summers. Foggy glass, water leaks, damaged frames, and worn seals are also common signs. New windows improve insulation, reduce maintenance, and boost curb appeal. At Window Lab, we help you choose the right window style and install it correctly for long lasting performance. A professional replacement can transform your home quickly.
