Homeowners in the greater San Antonio area trust their window replacement needs to Renewal by Andersen® of San Antonio. We are the area’s exclusive retailer of Renewal by Andersen® replacement windows and doors, bringing more than 100 years of design and manufacturing innovation direct to your home.

Renewal by Andersen is one of the most trusted names in replacement windows and patio doors in America.

  • Custom Sizing. Each replacement window and patio door we install is custom-sized and made specifically for your home to ensure a perfect fit – every time. That results in a smooth, stress-free window replacement process, no need for expensive wall renovations, and a snug fit that keeps the weather outside where it belongs.
  • Fibrex® Frames. Our replacement windows and doors are manufactured with our own exclusive Fibrex frame material. Fibrex is a composite that uses recycled materials to create a durable, rigid frame that is stronger than wood, vinyl – even steel. Because Fibrex is so strong, we can make our window frames narrower to allow for more expansive glass area.
  • High Performance™ Low-E4® Glass. You can choose from two glass packages that can save you money on your energy bills. High Performance™ Low-E4® glass is 45% more energy efficient in summer and 56% more energy efficient in winter as compared to ordinary dual panel glass.* Even better, our High Performance™ Low-E4® SmartSun™ glass is 70% more energy efficient in summer and 45% more energy efficient in winter as compared to ordinary dual panel glass.*
  • Wide Range of Styles. You can choose from an incredible assortment of window styles to complement your home’s architecture and décor. From traditional looks like double hung and picture windows; to the clean, modern lines of casement and sliding windows; to the elegant curve of an expansive bay window – we’ll fit your style!
  • Professional Installation. Our affordable replacement windows come complete with installation by our factory-trained window professionals. Our 7-step installation process means you know what to expect and when to expect it, reducing worry and speeding your window replacement project.
  • Renewal by Andersen Warranty. Renewal by Andersen has such confidence in the quality and value of its products that they offer one of the strongest warranties you’ll find in the industry.**
