Windows don't need replacing just because they're old. Condition, operation, and performance matter.

Signs worth evaluating

Look for rot or deterioration, failed hardware, windows that won't open or close correctly, persistent drafts, moisture between panes, recurring water intrusion, and significant frame damage.

Can the problem be repaired?

Sometimes. Hardware, weatherstripping, glazing components, and other parts may be repairable depending on the window.

What are you trying to improve?

Replacement decisions may involve comfort, air leakage, water intrusion, appearance, operation, noise, and maintenance. Be clear about the problem you're trying to solve.

Don't rely only on energy-savings claims

Energy performance matters, but actual savings depend on the existing windows, the climate, the house, and the installation.

Compare the full installation

Ask:

  • What window is being installed?
  • How will the opening be prepared?
  • How will water management be handled?
  • What trim work is included?
  • What warranty applies?
