Window replacement is the process of removing your existing windows and installing new units that seal tighter, insulate better, and operate smoothly for decades. Whether a few sashes have failed or the whole house needs updating, the goal is the same: a weathertight, energy-efficient opening that looks right and lasts. As Marietta homeowners ourselves, we help you choose the right window style, frame material, and glass package for Georgia’s heat, humidity, and storm season — then install it correctly the first time.

Window Replacement FAQs
How long does window replacement take?
Most windows are installed in 30–60 minutes each. A typical whole-home project of 8–12 windows is completed in one to two days once your custom units arrive.
Do I need a permit to replace windows in Marietta?
Like-for-like replacements that don’t change the opening size usually don’t require a permit, but enlarging an opening or adding an egress window does. We handle Cobb County permitting when it’s needed.
How much does window replacement cost?
Most residential windows fall between $450 and $1,200 installed, depending on size, frame material, and glass package. We provide a written, itemized estimate at no charge.
