Fiberglass Windows for Baltimore Weather: Are They Worth It?

What Baltimore Climate Does To Windows

Baltimore homes deal with a mixed bag of conditions that can punish a weak window frame. Summer humidity can make cheap frames swell, winter cold can make them contract, and repeated movement slowly opens up gaps, drafts, and seal failures.
