“Acadia Building Company did an amazing job on our home. We had a unique and challenging lot in the Boise Foothills. Acadia met the challenge with experience and the skill set necessary for our home. Our project went smooth from start to finish. I would recommend Acadia Building company to anyone.”

“How do you write a review about an extraordinary company? We’ll give it a try. We’ve had other homes built in the past, but those processes were nothing like building with Acadia Building Company and Nate Mason. First, we called his references. They ALL shared their positive experiences, telling us of Nate’s superior communication skills, bidding process and staying on budget and on time. We were sold. Now we want to share the same experience, telling you that everything Nate’s clients said is true. Acadia is truly a CUSTOM BUILDER. We searched the Treasure Valley, but most “custom” builder options allow you to select only interior finishes, etc. We designed our home and Nate made our dream come true. We love our new home. We cannot say enough good about them. Acadia Building Company is an outstanding company. Best builder in the valley.”

“I can highly recommend Acadia Building Company and led by Nate Mason! This is the 5th home I have built, and I can say with all certainty that Nate Mason is a competent and professional building contractor. My house was not an "easy build", but Nate was dedicated, hardworking, transparent, and he followed through. His sub-contractors are efficient and skilled, and they get the job done in a timely manner. Throughout the process, Nate was responsive to all of my questions and concerns, and I am now living in a beautiful home of outstanding quality. Thank you Nate Mason, and thank you to the whole team at Acadia Building!”

“Nate only uses top notch contractors and sub-contractors, not one of whom were a disappointment to us. On the contrary, some of them even made suggestions about how to actually improve things! The framing contractor made several suggestions and after seeing the final product, we were so glad we went with those changes. His trim carpenter is phenomenal and built all of the huge beams in the great room and master bedroom! Most importantly, our home was built "on time" and "on budget"! Our "Forever Home" is the actual Ridgemont featured on the Acadia Building Company website, and we are honored that Nate has utilized it in his profile page!!”
