Signs It’s Time to Replace Your Windows

Drafts Are Creeping In: Feel that cold air even when everything’s shut tight? That’s your windows giving up on insulation. Not ideal in a Philly winter.

They Stick, Squeak, or Just Won’t Budge: Opening a window shouldn’t feel like a workout. If they’re jammed or creaky, it’s probably time.
Visible Damage or Rot: Cracked glass or warped frames don’t just kill the vibe—they mess with security and energy efficiency.
They Just Look… Old: Let’s be honest. If they’re ruining your home’s curb appeal, why keep them around?
