See what our customers are saying:
My wife and I found ourselves in a sticky situation after the wind storms in early November 2017. Seventy mile an hour winds had stripped the well weathered shingles off the roof of the 1886 30 x 40 hay barn at our farm on the outskirts of Augusta. I reached out to several local builders in Augusta and Waterville and their response was lackluster at best.

On November 9th, I was returning home from Rockland on Route 17 and noticed the Castle Builders signs at the former Agway. I stopped in and met the owners and staff and arranged for an estimate. We decided to replace the roof with architectural shingles and to do some light carpentry underneath. They gave me a start date during the second week in December. I was thrilled when they arrived three weeks early and completed the job a full two weeks ahead of schedule. Their crews were respectful and easy to talk to and the workmanship and clean up were excellent. I won't hesitate to call them next time. 

Now it is time to transform your dream from concept to complete. To find out how, visit our showroom in Union, on Facebook, call us at 207-785-2020 or email us at  We will visit your home to talk ideas, review your estimate, answer questions and schedule your project. Let's get building!
