Pro Tips for Window Replacement

Do Insulation First

Windows often make less impact than insulation. Get your Home Energy Assessment to prioritize.

Get Multiple Quotes

Window prices vary significantly. Get at least 3 quotes from reputable installers.

Keep NFRC Labels

You'll need the NFRC (National Fenestration Rating Council) labels to claim rebates.

Consider Triple-Pane

For cold MA winters, triple-pane windows offer better insulation (and may qualify for higher rebates).
