How to Replace Windows in a Capitol Hill Rowhouse Without Losing Character

Begin By Reading The Existing Window
In a Capitol Hill rowhouse, the hardest part of window replacement is not picking a product, it is deciding what should stay and what truly needs to go.

A rowhouse window that rattles or leaks air is not automatically a candidate for total replacement. Sometimes the better move is to restore the sash, improve the seals, and keep the original proportions intact.
