Historic Home Window Upgrades Without Losing Character

Old windows give a house its face, yet they often come with loose sashes, tired glazing, and glass that does little for comfort. The trick is knowing which upgrades protect the character of the home and which changes will make it look out of place.

Assess The Existing Windows Before Choosing An Upgrade

Some are beyond repair, but many just need restoration, weatherstripping, or new components to work well again. Often the real issue is minor deterioration at the joints or worn seals around the opening.
