Duncan Windows did such an amazing job putting a door in where a window was. Super happy with this company. A friend told me that he used to do windows and he would have charged $1000 more than Duncan did for such a tough job. The door is beautifully crafted and really well installed! I’m going to have Duncan’s do all my windows!

Duncan’s Window & Door was great to work with from the first phone call through the completion of the job. Micah was very knowledgeable about his products and there absolutely NO pressure to purchase or upgrade from what you wanted/needed. They were the only company that was upfront with pricing and didn’t try to upsell me. I ordered windows and when they arrived Micah and his team installed them perfectly. I couldn’t be happier with the entire process and plan on using them again for additional windows, doors, and exterior projects. Highly recommended!
