Darby is one of Delaware County’s oldest and most historically significant communities — a borough settled in the 17th century where Main Street’s historic corridor gives way to Victorian-era homes, early 20th century row homes and twins, and the kind of architectural character that only comes from generations of community life. Darby Creek winds through the borough, and the residential streets that fan out from the historic downtown have been home to working families for over a century.
That history comes with a practical reality: Darby has some of the oldest housing stock in all of Delaware County. Victorian-era homes with original or near-original windows approaching 100 years old. Early 20th century row homes and twins where the aluminum replacement windows installed decades ago are themselves now aging out. Every cold Pennsylvania winter makes the case for replacement a little more urgent — and every energy bill reinforces it.
We’re the Andersen Certified Elite Contractor serving Darby and all of Delaware County. Over 20,000 windows and doors installed across Pennsylvania, New Jersey and Delaware. Most installations completed in 1-2 days. Price Match Guarantee.

Darby’s housing stock spans more eras than almost any other community in Delaware County. Victorian and Edwardian homes near the historic Main Street corridor. Early 20th century row homes and twins throughout the residential grid along Chester Pike and Highland Avenue. Mid-century construction on the borough’s newer sections. Each era presents its own window replacement reality — and we have the Andersen product range and installation expertise to address all of them.
We install Andersen replacement windows throughout Darby borough and surrounding Darby Township communities. Our factory-certified crews are experienced with every home type in this part of Delaware County and finish most Darby installations in a single day.
Double Hung Windows
The dominant choice for Darby’s row homes, twins, and colonials. Classic look, easy to clean, compatible with every era of Darby’s architecture.
Casement Windows
The original configuration in many of Darby’s older Victorian and Edwardian homes. Popular for kitchen and hard-to-reach installations.
Bay & Bow Windows
Add interior space and curb appeal to Darby’s larger Victorian and colonial properties along the historic corridor.
Picture Windows
Fixed panels that maximize natural light in Darby’s living rooms and parlors.
Sliding Windows
Smooth horizontal operation for Darby’s mid-century ranch and split-level configurations.
Awning Windows
Hinged at the top for ventilation in any weather. Common in Darby’s older basement and bathroom configurations.
Entry doors are particularly important in Darby’s older row homes and Victorian properties — original wood doors that no longer seal properly are a significant source of energy loss in the borough’s oldest homes. We install Andersen and ProVia entry doors, patio doors, and sliding glass doors throughout Darby. Most Darby door installations completed in a single day.

As an Andersen Certified Elite Contractor we install the full Andersen line for Darby homeowners. For Darby’s oldest Victorian and Edwardian homes we typically recommend the Andersen A-Series or 400 Series Woodwright for period-appropriate aesthetics with modern performance. For the borough’s row homes and mid-century construction the 400 Series or 100 Series Fibrex delivers the best combination of energy efficiency and value. We make specific recommendations during your free in-home consultation.
