Window Replacement Mount Airy
Mount Airy’s twins and semi-detached homes, built from Wissahickon schist, brick, and stucco, trace back to the early 1900s when rural estates became a streetcar suburb. A century of settling has shifted the original window openings in these masonry walls, so single-pane and early replacement windows rarely seal tight anymore. Thompson Creek Window Company manufactures custom vinyl windows at its own 70,000 sq ft Maryland facility to match the exact dimensions of each home’s openings, not a generic stock size.
The city’s own Mt. Airy 2025 Action Plan recognizes this century-old housing stock as one of the neighborhood’s defining assets, worth protecting with quality, precisely fitted upgrades.
Exact Fit for Settled Schist and Masonry Walls
Mount Airy blocks contain homes where original window openings have shifted in the stone and brick over 100-plus years. Stock windows leave gaps that let in drafts and water. Thompson Creek measures each opening on site and builds replacements to those exact dimensions. Every window carries a 50-Year No-Hassle Warranty and is AAMA-tested to withstand winds up to 146 miles per hour.
Matching Styles from Sedgwick Farms to the French Village
Sedgwick Farms features English cottage and Tudor Revival homes built 1900-1910. Pelham mixes Colonial Revival, Jacobean, Italianate, Queen Anne, Greek Revival, and Dutch Colonial styles dating to 1894-1917. The French Village added 24 European Revival homes between 1924 and 1929. Each style calls for different window proportions that only custom manufacturing can supply.
Philadelphia’s EZ Permits program covers most exterior window replacements without a separate permit, unless the home is historic or commercial, which keeps most Mount Airy projects simple.
Thompson Creek also replaces windows in nearby Chestnut Hill, Germantown, and Manayunk along the Germantown Avenue corridor, and offers the same custom-fit approach through its citywide Philadelphia window replacement service.
