Partner with an Andersen-Certified Contractor
Castle Windows is proud to be an Andersen-certified contractor, meaning every installation meets the rigorous standards of one of the most trusted names in the window industry. This credential reflects our specialized training, proven installation expertise, and access to Andersen's premium product line.
Our partnership also means Castle Windows' installers don't just sell Andersen products. We’re trained to properly measure, fit, and seal Andersen's window and door systems. That specialized knowledge matters because even the best-engineered window can underperform if it's installed incorrectly.
Being certified also gives homeowners access to Andersen's innovative products, from advanced glass technologies to weather-resistant frame materials.
In short, the Andersen partnership isn't just about the products on the truck. It's a commitment to a standard of workmanship that protects your investment long after installation day is complete.

FAQs About Window and Door Replacement
-
Are all-wood windows a good choice for an older or historic home?
They can be a good architectural fit where natural materials, traditional proportions, and existing trim are important. The project may also require attention to sash dimensions, decorative details, opening condition, and local preservation requirements. A consultation can help determine whether repair, an insert window, or full-frame replacement better fits the home and project goals.
-
Is installation work available year-round?
Yes. Our installation crews work year-round. Ask about shifts, employment classifications, and seasonal workloads for a specific position.
-
How do awning windows compare with casement windows?
Both styles open outward, but awning windows are hinged at the top while casement windows are hinged at the side. The better fit depends on the opening, preferred ventilation direction, privacy needs, exterior clearance, and how you want to operate the window.
-
Are Castle Windows locations independently operated?
We can’t confirm from the available information whether individual locations are independently operated or managed through one corporate structure. Contact us directly if the operating structure or responsibility for service in your area affects your project or warranty request.
-
Does Raynor provide a residential garage door warranty?
Raynor warranty coverage varies by product, component, purchaser, property type, and installation circumstances. Review the manufacturer’s written warranty for the exact product selected. Also confirm whether the installer provides separate coverage for labor or installation-related concerns, since manufacturer and installer responsibilities aren’t necessarily the same.
-
What is the difference between double-hung and single-hung windows?
Both styles have vertically arranged sashes. A double-hung window allows both the upper and lower sashes to move, while a single-hung window typically has only one movable sash. The appropriate choice depends on ventilation preferences, cleaning access, design, budget, and the existing opening.
