“I had an excellent experience with Mangan Excavation. I'm not sure how much of Washington cty they cover, but they quoted a family member of mine in Barre so I believe it's in their service area.”
“Thanks to Gideon from Mangan Excavation LLC for nice work and quick turnaround!!”
Gideon and his team have been incredible to work with. Great communication and they have done incredible work to get our home up in a timely manner. We could not have asked for a better crew to work on this project. Highly highly recommend working with them!
Mangan Excavation is an excellent business with the best team and practices. They installed a complex septic system for me in a challenging environment and accomplished it with top notch work, communication and professionalism. They were easy to work with and the end result was beyond my expectations. I would highly recommend them for any project. They are reasonably priced as well. We are lucky to have a company like this in our area.
Gideon does our plowing and also has excavated / buried a propane tank for us, and done some grading. He's great — responsive, first, and then does a careful and professional job.
Gideon and crew were great! I had two emergency situations this winter and he responded almost immediately. He made recommendations and followed through to solve the problems...no stress no hesitation! They will always be my go to guys! Thank you Gideon and crew!!
This is the second time we have used Mangan excavating. The work he did the first time in August 2022 was so amazing. This year in April 2025 we had a family emergency when our septic system failed. We got the design done. Had a contractor lined up, but unfortunately, it did not work out. I called him after hours and informed him of our situation. On Monday, I was at his shop with the plans. Not even 10 days later he was at my house. He put in a complete mound system in under 10 days. During that time. I was only without a working toilet for less than four hours. I appreciated the fact that he understood the emergency we were under as a family of eight. I greatly appreciate the fact that he was able to work around my chicken coop, as well as my garden. I would recommend him every time!
