Energy Efficient Window Replacement

Renewal by Andersen’s 4-step hassle free process helps to take the hassle and confusion out of window buying. From the initial consultation to the window installation itself, we are with you every step of the way in order to make the process as seamless as possible.

Our windows are constructed with a proprietary Fibrex® material that is made of reclaimed wood fibers and composite polymers. As a result of using Fibrex® our windows are stronger and more durable than both wood and vinyl windows.

You can choose from seven window styles that are fully customizable at every stage of the process. We offer a range of colors, shapes, hardware options and grille patterns so you can build the perfect window that matches you and your lifestyle.

Fall in Love with Your View

The composite Fibrex® material of our Andersen windows make it possible for narrower frames to hold larger pane glasses, which means you see more of what you want to – the view. The extrusion process also allows our windows to bend into just about any shape, from hexagonal to right triangles and more so you can improve your curb appeal and match your home’s unique style even easier.

The process in which Renewal by Andersen custom-crafts your windows will fuse the color into the frame, allowing for more interior and exterior color opportunities – including black. Our windows are guaranteed not to crack, peel or fade over time, and they will operate just as well in 20 years as the day you bought them.

Discover the possibilities by scheduling your free in-home consultation today!

Energy Efficient Patio Doors

Renewal by Andersen San Diego also offers energy efficient patio doors. Our patio doors come in three styles and are fully customizable throughout every step of the process. Bring the outside in with a contemporary sliding glass door that features the largest glass area, or accentuate your patio or garden with a classic French style hinged patio door. Our third option is a French sliding patio door that combines the best of both styles.

All our patio doors come with a 5-point locking system that works to improve their energy efficiency and add a layer of security for enhanced peace of mind. Customize them with a range of hardware, colors, and optional grille patterns.

Renewal by Andersen Signature Fibrex® Material

Made from 40% recycled wood fiber by weight, Fibrex® provides the strength of wooden windows with the versatility of vinyl.
The unique blend of Fibrex® material allows your windows to be supported by narrow frames for a wide, sleek glass area.
Fibrex® frames are completely saturated with color during manufacturing, so you never have to worry about paint cracking or flaking off.
All Renewal by Andersen windows are also guaranteed to function just as well as the day they were installed, so frames will never expand or bow.
