New Jersey Window Experts

Stern Windows is a trusted window installation contractor serving Northern New Jersey. Unlike large window service providers in the area, we are not affiliated with national corporations. What sets us apart is our strong local presence, personalized service, and commitment to long-term quality.

Locally Operated

We are proud to be part of the New Jersey community. We hire locally, invest in training, and create long-term career opportunities for window installers and support staff. We actively support local organizations and community initiatives, serving our clients not just as customers, but as neighbors—delivering attentive, personalized service on every project.

Family-Owned

Our owners live in the communities we serve, and their children attend the same schools as many of our clients’ children. This close connection motivates us to contribute to a strong, well-connected, and sustainable local community through honest work and dependable window solutions.

Highly Responsive

Unlike large corporate window companies that rely on automated calls, texts, and emails, Stern Windows provides direct communication with real people who are dedicated to client service. This ensures clear scheduling, timely updates, and peace of mind throughout the project. After installation or replacement is complete, we remain available for follow-up visits and to answer any questions that may arise.

Full-Service Window Contractor

Stern Windows is a full-service window contractor offering window system design and consultation, window installation and replacement, window repairs, energy-efficient upgrades, and specialty window solutions for residential and commercial properties.

Like larger providers, we also offer window installation financing, allowing our clients to improve their homes without worrying about immediate upfront costs.
