My husband was home because of a foot surgery so he was able to see Don and Earl work very well together. Out treehouse was not easy because we had slanted walls and tilted/crooked windows to make it fun which required many unique cuts. Don and Earl went over and above our expectations. They installed our slide, rock wall, and climbing rope so our kids could play on it while they completed the house section. I thought that was incredibly thoughtful. They also came back and installed our accessories, built an awesome railing out of tree branches, and a custom tree branch ladder for our trap door. They were both so creative and added so many fun touches to our treehouse!
