With over 40 years in business, Custom Windows is a top choice for replacing home windows in Houston, Spring, The Woodlands, Galveston, Katy, Sugar Land, and surrounding areas. Whether you need to increase your property value, customize your existing look, or save on energy costs, our team is ready to assist you in choosing the perfect window. Unlike most window replacement companies, we’re focused on your needs, not the bottom dollar.

From hurricane-rated impact windows to noise reduction windows, we have a wide variety of energy-efficient window products to suit your needs. Together with our professional installation and trusted design solutions, we promise to replace your windows with excellence.

Quality Door Replacement

In Houston and the Gulf Coast, the heat and humidity can take a toll on existing doors and be a major source of energy loss. Upgrade your home by installing a new entry door, sliding patio doors or French doors in your home that withstand our weather climate.

With installation precision and high-quality standards, the Custom Windows team is committed to adding value to your entry doors. We provide a range of door styles including fiberglass, vinyl, clad wood, aluminum, and moving glass wall systems to fit your home.

Working with Top Brands

As one of the few seasoned window and door companies near the Gulf Coast, we are proud to offer high-quality window and door products from Houston’s leading brands. In addition, we have partnered with the top window and door manufacturers to provide a wide range of window styles for you to choose from.

You can choose from high-quality manufacturers like ProVia, NT, American Window Systems, Sierra Pacific, MI, and other recognized door and window brands.


How can I prepare my house for replacement windows or doors?

A good rule of thumb is to move furniture to provide at least 3 feet of clear area around every window or door being replaced.

How will the installation affect the surrounding wall? Will I need to repaint?

While there is always a possibility of small nicks, we make every effort to minimize this and typically there is no need for any touch-up after installation.

Do I have to replace all of my windows at the same time?

No, we can do as few or as many as you would like. But the improved comfort and reduced noise that you will see in rooms with new windows will make you want to do them all as soon as possible!

What is the warranty for replacement windows and doors?

Each manufacturer has slight differences in their warranties which we will cover in detail with you. Keep in mind that Custom Windows has been serving the Houston market for over 40 years. Businesses have this longevity only by taking care of their customers! View warranty information.
