About Castle Windows

A Family-Owned Window & Door Company

We are professionals, from our sales team to our service department, and we've been bringing quality windows, doors, siding, and roofing to homeowners across 11 states since 1977. We like to keep a fun, family culture in our offices, because that's genuinely how we see the people we work with. We call ourselves the Castle family, and we treat our customers like they're part of it. There's never a dull moment at Castle.

Every project starts with a one-on-one consultation, so you know exactly what you're getting before any work begins, and unlike a lot of companies in this business, our windows are designed, engineered, tested, and manufactured in our own North American factories rather than a supplier's.

At Castle, we are proud to be listed year after year as one of the largest home improvement companies in the country. We are also highly awarded and continually rank among the best in sales, installation, and service.

Backed for the Life of Your Home

Our lifetime warranty means lifetime, literally: leaks and drafts, vinyl, color, glass, seals, parts, screens, and window operation are all covered for as long as you own your home, with no pro-rating. Look closely at most competitors' warranties, and you'll find installation excluded entirely. Ours isn't. A well-built window fitted poorly is still a bad window, so we stand behind both halves of the job, including free service labor, rather than pointing you back to a manufacturer.
