So what makes Dun-Rite different?
First off, Dun-Rite will not give quotes over the phone. Asking how much a window is, is like asking how much a red car is. What type of window are you looking for, what options will work with your space, what floor is it on, what kind, color, and material do you like? All of these answers help dictate the cost, design, and layout of your window project.
To get you an accurate cost and the information you need, we will meet with you in your home. At Dun-Rite, we look to see how your house is built, what we need to do for the frames, what exterior and interior materials will we be working with, and where your new windows will be installed. But most important, we want to get to know you, in person.
After meeting with one of our In-Home designers you will receive a guaranteed price. What does that include?
