Vinyl vs. Wood vs. Fiberglass Windows for Baltimore's Climate

Between humid summers, cold snaps, coastal air, and older housing stock, Baltimore is a tough place to pick the wrong window material. A frame that looks fine in a showroom can behave very differently once it is sitting in a rowhome in Canton, a brick colonial in Towson, or a porch-facing house in Roland Park.

The best choice usually comes down to how the house is built, how much maintenance you are willing to do, and whether the replacement needs to fit a historic facade.

What Works Best In Real Baltimore Homes
