When it’s time to replace your windows, you don’t want just any contractor. Your windows shape how your home looks, feels, and functions, so you want a team that understands New Jersey homes, weather, and homeowners' expectations. Hunterdon Roofing, Siding & Window Co. has been improving homes across Central New Jersey since 1974. As a third-generation, family-owned company, we bring decades of hands-on experience and a local perspective you won’t get from out-of-state crews.
From colonial homes in Flemington to ranch-style houses in Clinton and condos throughout Somerset County, local properties have distinct character. We install high-quality, energy-efficient replacement windows designed to complement your home’s style while standing up to icy winters, humid summers, and everything in between.
Why New Jersey Homeowners Choose Hunterdon for Window Replacement
Older or underperforming windows can cause drafts, higher energy bills, and a tired exterior appearance. With Hunterdon on your side, upgrading your windows delivers real, noticeable benefits:
A More Comfortable Home: Our replacement windows provide excellent insulation, helping keep cold air out in winter and heat at bay in summer.
Improved Energy Efficiency: Modern window systems reduce air leakage and improve thermal performance, easing the workload on your HVAC system and supporting long-term energy savings.
Boosted Curb Appeal: Updated windows can dramatically improve the look of your home, whether it’s a traditional colonial or a more contemporary design.
Lower Maintenance: No more sticking sashes, peeling paint, or constant upkeep. Today’s windows are built to look good and function smoothly for years.
Increased Home Value: In New Jersey’s competitive housing market, new windows are an upgrade that buyers notice and appreciate.
Window Styles to Match Your Home’s Personality
At Hunterdon Roofing, Siding & Window Co., we know New Jersey is filled with unique characters who want a home that reflects their style. That’s why we offer windows in an array of styles, including:
Double-Hung Windows: A classic choice with tilt-in sashes for easy cleaning.
Casement Windows: Hinged and crank-operated for excellent airflow and a clean, modern look.
Awning Windows: Top-hinged and ideal for bathrooms or areas where privacy and ventilation matter.
Bay Windows: Create an open feel, add natural light, and enhance curb appeal.
Bow Windows: Add architectural interest to your home’s exterior with a graceful curved window design.
Sliding Windows: Space-saving and easy to operate, perfect for kitchens or basements.
Picture Windows: Fixed windows that frame outdoor views and maximize natural light.
Custom & Specialty Shapes: Architectural, geometric, or decorative options for truly unique homes.
We also provide HOA-compliant and ADA-adaptable window options, helping simplify approvals for condos and association-managed communities, because dealing with a New Jersey HOA is already enough work.
Built for New Jersey Weather and Energy Performance
New Jersey weather has a reputation for keeping homeowners on their toes. That’s why our replacement windows are built with materials designed to handle it all, including:
Multi-pane glass to improve insulation during winter cold snaps and summer heat waves
Advanced weatherstripping to reduce drafts and seal out moisture
Energy-efficient frames and materials built to withstand temperature swings
Improved U-values that help maintain consistent indoor temperatures
Optimized Solar Heat Gain Coefficient (SHGC) ratings to balance natural light and heat control
The result is a more comfortable home, better energy efficiency, and windows that perform reliably no matter what the New Jersey forecast decides to do next.
