Oskaloosa is a welcoming Mahaska County community, home to William Penn University and a beautiful central town square. The city features well-preserved historic homes near downtown, established mid-century neighbourhoods, and a strong sense of community pride rooted in its Quaker heritage.
Oskaloosa's southeastern Iowa location brings cold winters with temperatures reaching -10F and hot, humid summers exceeding 90F, creating year-round demand for well-insulated, properly sealed windows.
Oskaloosa's older homes near the town square and William Penn campus include many properties with original windows that are major energy wasters. Modern triple-pane replacements provide the thermal protection needed for Iowa's harsh winters while preserving the historic character of these charming homes.

Our home near the Oskaloosa square had windows from the 1920s that we loved for their character but hated for their drafts. Panes crafted custom windows that match the original look but keep us warm all winter. — Beth T., Penn Heights
