Avondale sits in the heart of New Garden Township, and is a small borough in southern Chester County surrounded by the Brandywine Valley countryside that has defined this corner of Pennsylvania for generations. The mushroom farms and open agricultural land that stretch between Avondale and Kennett Square to the northeast give this community its distinctive rural character, and the Route 41 corridor connecting Avondale to the Delaware border to the south keeps it well-connected without the density of the county’s northern communities.
Southern Chester County’s four-season climate is not gentle on buildings. The open landscape means more wind exposure, harder winters, and the kind of sustained cold that finds every gap in a window’s seal. In Avondale’s older borough homes — the late Victorian and early 20th century properties along Tawawa and Rosehill streets and the surrounding residential blocks — original or early-replacement windows have been fighting that climate for decades. In New Garden Township’s rural and semi-rural properties, farmhouses and older colonials face the same exposure on larger lots with even less shelter from prevailing winds. The result in every case is the same: windows that no longer perform, drafts that make rooms uncomfortable, and energy bills that reflect every failure every month.
We’re the Andersen Certified Elite Contractor serving Avondale and all of southern Chester County. Over 20,000 windows and doors installed across PA, NJ and Delaware. Most installations completed in 1–2 days. Price Match Guarantee. The right contractor for Avondale’s borough homes and New Garden Township’s rural residential properties.
Avondale’s housing stock divides clearly between the borough core and the surrounding New Garden Township. In the borough — on Tawawa Street, Rosehill Street, Pennsylvania Avenue, and the residential blocks around Avondale’s small downtown — the construction is predominantly late 19th and early 20th century. These are older properties with original or early-replacement windows that have been on the to-do list for years in some cases. In New Garden Township, the residential mix includes genuine farmhouses on large agricultural lots, older colonials, postwar ranches and split-levels, and newer residential development along the Route 41 corridor that draws families to the area for the Kennett Consolidated School District.
Across all of it, the window replacement case is clear. Older homes where the original windows have been failing slowly for years. Rural properties where the exposure to the elements accelerates the degradation of frames and seals. Newer construction where builder-grade windows have reached end of life. We install Andersen replacement windows throughout Avondale and New Garden Township — every window a genuine Andersen product, every installation backed by our factory-certified crews and Andersen’s industry-leading warranty.
Double Hung Windows
The most practical and most popular choice for Avondale’s borough homes and New Garden Township’s older residential properties. Both sashes tilt in for easy cleaning, excellent ventilation, and a classic profile that works across every era of housing stock in southern Chester County.
Casement Windows
Hinged at the side for maximum airflow and a tight energy seal when closed. Particularly valuable in Avondale’s older properties and in New Garden Township’s rural homes where energy performance against winter exposure is the priority.
Bay & Bow Windows
Project outward from the home, adding interior space and curb appeal. Found in Avondale’s larger Victorian borough properties and in the township’s older farmhouses and colonials where original bay configurations are part of the home’s character.
Picture Windows
Fixed panels that maximize natural light and frame views. Popular in New Garden Township’s rural and semi-rural properties where homes are oriented toward the Brandywine Valley countryside and open agricultural landscape.
Sliding Windows
Smooth horizontal operation, low maintenance. The natural replacement for aluminum sliders in New Garden Township’s postwar ranches and in the newer residential construction along the Route 41 corridor.
Awning Windows
Hinged at the top for ventilation in any weather. A practical choice for Avondale’s older borough basement and bathroom configurations and for New Garden Township’s farmhouse and rural residential installations.
Avondale’s door replacement needs run the full range. Original wood entry doors in the borough’s older Victorian and early 20th century homes that no longer seal against the cold. Farmhouse doors in New Garden Township that face the full force of the Brandywine Valley’s open-country wind exposure. Patio and sliding glass doors in the township’s postwar and newer construction that have reached the end of their useful life. In every case, a genuine Andersen or ProVia replacement installed by certified crews delivers an immediate and lasting improvement.
We install Andersen and ProVia doors throughout Avondale and New Garden Township, handled by the same Andersen Certified Elite crews that install our windows. Most Avondale door installations completed in a single day, backed by manufacturer warranties and our own installation guarantee.
Entry Doors — we install Andersen and ProVia entry doors in fiberglass, steel, and wood options. For Avondale’s older borough properties, a quality entry door replacement delivers immediate improvements in security, energy performance, and the home’s street presence in a community where neighbors notice.
Patio Doors — Andersen patio doors in French door and gliding configurations. Popular in New Garden Township’s single-family properties and farmhouses where rear yard, garden, and outdoor access is a central feature of the property.
Sliding Glass Doors — smooth, secure, and energy efficient. Andersen sliding glass doors replace worn originals in Avondale’s postwar and newer township construction with a clean, durable upgrade built for Chester County’s four-season climate.
French Doors — classic hinged door pairs for patio and garden access. A natural architectural fit for Avondale’s Victorian borough properties and for New Garden Township’s older farmhouses and colonials where a traditional door configuration suits the character of the home.

Built to handle the exposure that southern Chester County’s open landscape delivers.
Andersen 200 Series
Wood interior with easy-care exterior. For Avondale’s older Victorian borough homes and New Garden Township’s farmhouses where interior wood finishes are architecturally important and homeowners want to preserve the character of the original construction.
