Call Castle Windows to Upgrade Your Home

Castle Windows has been helping homeowners update the look and performance of their homes since 1977. Our family-owned company works across 11 states. To date, we’ve helped more than 1.2 million customers with window and door projects, and we’re ready to help you next! 

Who We Are & What We Stand For

We stand for respect and quality service, and that shows up in the relationships we build with our employees and our customers. 

We refer to our team as “The Castle Family” because we truly see ourselves as one unit working together for the benefit of our clients. We stand behind our products and our service, full stop. 

That means…

• Every project starts with a free, one-on-one consultation, no pressure attached. 
• Once the job is done, our lifetime warranty covers both the product and the labor to install it, including leaks, drafts, vinyl, color, glass, seals, parts, screens, and window operation. 
• There’s no pro-rating for as long as the homeowner owns the house. 

Windows

Windows are where we got our start. We design, engineer, and manufacture our own vinyl windows in North American factories. 

Our replacement windows include: 

• Awning windows 
• Bay and boy windows 
• Casement windows 
• Double-hung windows 
• Garden windows
• Glass block windows 
• Slider windows 

We’re an Anderson-Certified Contractor 

As an Andersen-Certified Contractor, we meet their standards for product knowledge and installation quality. 

When you work with us, you get access to Andersen's window lineup alongside our own manufactured options, giving you an expanded menu of choices for style, material, and energy performance.

Doors

Doors are the other half of our business, and we install Andersen doors and ProVia entry doors. 

• For front and back entrances, we install ProVia doors in steel and fiberglass. 
• For patio openings, we install Anderson doors. 

ProVia Doors

We hold Platinum Plus Dealer status with ProVia, known for entry doors featuring reinforced cores and detailed finish work. 

Other Services

We also offer siding and roofing in Mount Laurel and Cedar Grove. Homeowners in these areas can turn to us for a full exterior update rather than juggling separate contractors for windows, doors, siding, and roofing.
