Window replacement by state
Each state sets its own rules for the companies that replace windows, and the climate decides which glass makes sense. Pick your state to see how licensing works there, where to look up a company and what the building code and climate mean for your windows.
Gray states do not have a page yet. We add states as we finish researching them from each state licensing board.

Why window replacement differs from state to state
Some states license or register the companies that do home improvement work, some only license larger projects, and some leave it to cities and counties. Each state page says which applies and links the official board or agency, so you can look up a company before you sign.
Building codes differ as well. Coastal states may set rules for windows that resist wind and impact, and some states add their own energy rules for new windows. Where a code applies, the state page links it.
Climate is the third difference. The ratings on a window label matter differently in a hot, sunny state than in a cold one, which is why the state pages point to the climate zone that applies there.
How to check an installer in your state
Ask for the company’s license or registration number where the state issues one, and look it up on the board’s own site rather than relying on a logo or a certificate shown to you.
Where the state does not license window installers, your city or county may require a registration or a permit. The local building department can tell you what applies to your address.
Where to get help in your state
Questions about a contract, a deposit or unfinished work go first to the company and then to the agency that oversees contractors in your state, or to your state consumer protection office. Each state page links the right office.
