***Every Renewal by Andersen window is a custom window. That is, each window is made to order. This page deals with replacement windows in special shapes, commonly called custom windows.***
Custom windows from Renewal by Andersen come in nearly every shape, size, design and color imaginable. Our custom window designs turn your oddly-shaped window opening into a work of art.
Our custom windows can fit nearly any opening. A certified Renewal by Andersen window professional can help you design the perfect specialty window “combination” to take advantage of your unique space.
We typically install custom windows on homes with existing specialty openings.
These large, elaborate window designs can improve the lighting inside your home by letting in natural sunlight. So we frequently advise customers to choose a spot that receives a lot of sunlight.
We install custom windows in large window openings in prominent places of a home, like:
Above the front foyer
In a forward-facing front room
Overlooking the backyard/back deck
Your custom window design will be completely unique and beautiful. The variety of combinations available from Renewal by Andersen, coupled with the size and shape of your window opening, virtually ensures your custom window design is one in a million.
A custom window design can transform the look of your house while adding value.
Forward-facing custom windows add immediate curb appeal and draw the eye to the most beautiful new feature of your home.
Especially if you live in a neighborhood where homes are very similar, a large custom window can immediately differentiate your house from the others on the block. This typically adds value to your home when and if you plan to sell it.
Renewal by Andersen carries a dozen different shapes and many custom window styles to choose from.
