Make the Right Choice in Windows. Choosing the right window for your home can be confusing and all too often time consuming. We believe these questions and answers will help clear up much of that confusion and allow you to select windows you'll enjoy for many years to come.

What's the best way to replace my old and drafty windows? You should certainly consider custom-sized windows for the very simple reason that they'll fit better. Stock-sized windows require extensive carpentry work both inside and outside your house. That can be very costly and inconvenient. Walsh Building Products' custom-sized windows, on the other hand, are manufactured to fit your existing window opening. You get the style and options you want while maintaining your glass area.
