Decide if you’re replacing windows for energy efficiency, aesthetic upgrade, functionality, or resale value.

Consider noise reduction, UV protection, and security as part of your goals.

Factor in costs for windows, installation, trim work, and possible repairs to framing.

Plan for a 10–15% contingency for surprises (like water damage around old frames).

Compare styles: double-hung, casement, slider, picture, bay/bow, or specialty shapes.

Match design with your home’s architecture and your lifestyle needs (easy cleaning, ventilation, accessibility).

Select materials (vinyl, wood, fiberglass, aluminum-clad) based on durability, maintenance, and budget.

Look for ENERGY STAR® rated windows appropriate for your climate zone.

Check ratings like U-Factor (insulation) and Solar Heat Gain Coefficient (SHGC) (heat control).

Consider double-pane or triple-pane glass with low-E coatings for efficiency.

Ask about their experience with your specific window brand or style.

Make sure the contract covers scope, cost, warranty, and cleanup.

Spring and fall are ideal—mild weather helps with installation and comfort while windows are out.

Installation may take a few hours per window, depending on the scope.

Prepare rooms by moving furniture, covering floors, and securing valuables.

Inspect for moisture damage, mold, or rot around existing frames before installation.

Consider upgrading trim, sills, or exterior finishes at the same time for a seamless look.

Balance upfront costs with reduced utility bills and increased comfort.

Choose styles and colors that will still look good as your home ages.

Consider resale value—buyers often see new windows as a major plus.
