Window Replacement Pennsport: Custom Sizes for Formstone Rowhomes
Pennsport features attached brick rowhomes built from the 1890s to 1940s that often carry formstone or Perma-Stone cladding on the outside. These mid-century facades sit right along the Delaware River, where extra humidity and moisture reach every wall. The South District Update from the City of Philadelphia covers this stretch of South Philadelphia housing stock in detail. The original window openings in these homes rarely match today’s stock sizes. Thompson Creek has helped Pennsport homeowners since 1980 with windows made at our 70,000 sq ft Maryland facility to fit those exact openings.
Formstone Challenges in Older Pennsport Homes
Formstone and Perma-Stone create uneven surfaces that standard windows cannot seal properly. Pre-war rowhomes along Two Street and near Jefferson Square Park often have openings that vary by several inches from house to house. Custom replacement windows from Thompson Creek solve these fit problems while handling riverfront moisture exposure. Homeowners in neighboring blocks often compare notes with East Passyunk window replacement projects, since both areas share similar pre-war construction.

Frequently Asked Questions
How does formstone affect window replacement in Pennsport?
Formstone and Perma-Stone create uneven surfaces around older openings, so custom-sized windows are needed for a tight seal against river humidity.
Do Pennsport rowhomes near the Delaware River need special window features?
Yes. Homes built in the 1890s to 1940s face extra moisture, so custom windows made at our Maryland facility help block drafts and leaks.
Can window replacement work on Two Street homes with non-standard openings?
Custom windows fit the varied sizes common in these pre-war rowhomes while keeping the formstone facade intact.
