Window Know-How: A Guide to Old-Building-Friendly Contractors

So, you want to repair your home's existing windows?

Did You Know?

Windows Map Inset

The average person in the United States stays in the same house for between five and seven years. When it takes upwards of 40 years to recoup in energy savings what was spent to replace windows, many owners will never see the "savings" or fully recoup their expenses.

Planning on staying in your home forever? With some basic maintenance and occasional repairs, your original windows can last for another 50 years or more.

Congratulations! You've made a great choice that says a lot about your commitment to your home's historic character – and your desire to save money. And instead of carting them off to a landfill and spending needlessly on higher-priced and lower-quality replacements, you've shown that you're confident increased energy efficiency goals can be met – and perhaps exceeded – by giving what you already have some TLC.

Now that you feel good about your newest home renovation project, we hope that you’ll find our interactive map helpful as a first step to finding qualified, old-window-friendly contractors in your area. As you browse, know that this growing list is not intended to be comprehensive, nor does the inclusion of a business or organization serve as a recommendation or an endorsement. We're just hoping to get you started based on what we've heard from other homeowners.

If you don't find what you're looking for here, don't fret. If you have historic windows, chances are others on your street do as well. Consider asking a neighbor for a referral, whether that means popping next door or sending out a query on your neighborhood listserv. Also, contact your State Historic Preservation Office and/or your statewide or local preservation organization and let them know about your project. Chances are they have tips and resources that can help.
