Window repair in Germantown, Philadelphia

Germantown has a very wide range of old houses, from colonial stone buildings to Victorian twins, and the windows reflect each period.

A neighborhood with deep roots

Germantown was founded in 1683 by German and Dutch settlers and the Battle of Germantown took place here in 1777. Germantown Avenue is the long spine of the neighborhood, lined with stone houses, later Victorian and Colonial Revival twins and large detached homes on side streets.

What that means for windows

Local stone: Many older Germantown buildings use Wissahickon schist, a local stone, with deep window reveals and wood frames set into thick walls.
Historic districts: Parts of Germantown, including the Colonial Germantown Historic District, are on the Philadelphia Register of Historic Places, so exterior changes go through the Philadelphia Historical Commission.
Large windows, many sizes: Victorian twins and large detached houses often have tall, heavy sash and custom sizes, which favors repair of originals over stock replacements.

Repair priorities

Check sills and frames for rot where porch roofs and bays shed water.
Look at sash weights and cords on tall windows, which can be heavy.
Ask about storm windows that fit unusual sizes.
Plan for lead-safe practices in houses built before 1978.

A note on scale

A large house can have thirty or more windows. Many owners repair the worst ones first and phase the rest across several seasons, and installers can write the scope window by window to support that.

Questions people ask

Is Germantown a historic district?

Parts of it are listed on the Philadelphia Register of Historic Places, including the Colonial Germantown Historic District. Check whether your address falls within a designated area.

Are custom-sized windows repairable?

Yes, and repair often costs less than making a custom replacement. Ask installers about their experience with large wood sash.

Do stone houses have different window problems?

The walls hold moisture differently from brick, so check flashing and sills, since moisture that collects behind the frame is common.
