Best Replacement Windows

Castle Windows is the only company in the window industry to be completely backed by a true lifetime warranty. Other window manufacturers may claim to offer lifetime warranties on their windows, but the fine print usually reads otherwise. They cover some things, but not the important elements that can go wrong with different types of windows. Whether you have wood, double-hung, fiberglass, or aluminum windows, we have you covered with our lifetime warranty.

If you need windows installed, check out our window offers, and get a window and door quote below. We’re still in business for over 40 years.

Call us anytime, day or night, at 1‑800‑360‑4400. A real person is waiting to speak with you.

If Castle could be summed up in three words, they would be family, reputation, and warranty. They all relate to and strengthen one another, and the reason we’re still in business after 42 years is due in large part to our true lifetime warranty.

The double strengthened panes of glass are durable & versatile enough for the most discriminating homeowner. Our double-hung windows feature a tilt-in top and bottom sash that allows for easy cleaning. Our virgin vinyl construction will keep your windows looking pristine for years to come.

Casement Windows​​

A casement window attaches to its frame by one or more hinges at the side. Windows hinged at the top are referred to as awning windows, and windows hinged at the bottom are called hopper windows.

All casements feature the security and ease of our multi-point locking system, and they can serve as windows for all seasons and homes.

Our beautiful and stylish virgin vinyl casement windows may be installed individually or in multiple combinations. Each casement window is constructed with high-quality stainless steel hardware to give you a lifetime of trouble-free operation, and our multi-point locking system provides you with the ultimate in security and convenience.

The detailed design of the casement window—with choice of optional grid patterns—allows you to perfectly match the overall design of your home.

We offer the following types of single casement windows:

  • Single Casement
  • Double Casement
  • Three or More Casements

Slider Windows

A lasting investment in beauty, design, and convenience, the slider windows’ multi-cavity construction and energy-efficient glass ensure years of durability and energy savings.

Garden Windows

Let the sunshine in by installing a garden window, your plants will be able to flourish year-round. Our garden window units are built with casements that operate for added ventilation, a sturdy plant shelf, and strong supports that stabilize the window for a long life and a perfect fit.

Bow and Bay Windows

Bow and bay windows broaden your view of the outdoors and will add distinction to any home. For your comfort and peace of mind, we’ve loaded these windows with features that make them more durable, energy efficient, and practical.

The head and seat of each bow and bay window are crafted using a 5/4″ marine plywood with real oak veneering, adding beauty and elegance to your home.

The strength of the bow stems from the factory-finished window supports that stabilize the unit, assuring many years of carefree service. This hand-selected veneer makes our window frame stronger than frames used by other window companies.

Our windows are not made with stapled construction, another budget-craftsmanship decision common in the industry. This strength ensures that the windows will never sag.

Stainless steel hardware and virgin vinyl construction provide years of smooth operation without the worries of maintenance or painting.

You can decorate the inside of your bow or bay window with plants, framed photos, glassware, holiday displays, and more. Enhance the appearance and value of your home—and expand the look of any room—with a Castle bow or bay window, custom-designed to your personal taste.
