When Restoration Makes More Sense Than Full Replacement

In Baltimore, many older windows fail because of paint buildup, worn pulleys, missing parting beads, or deteriorated sash cords rather than total structural failure.

What happens if the opening is not square or the wood is damaged inside the wall? Can you match the historic profile as closely as possible?

They separate contractors who have actually worked on Baltimore rowhouses from crews that only know how to install modern units in standard openings.
