All reviews for Mangan Excavation LLC

I called Gideon to replace the septic tank at our new house, after a different contractor left us in a bad situation. He was very responsive, was on the job replacing the tank in a matter of days after calling so we could have the work finished before the ground froze. Mangan Excavation did a great job with work and clean up. I will use them again.

Mangan Construction replaced my 75 y.o. concrete seawall. Their work was professional, affordable and Gideon always responded to my many questions promptly. My wall came out beautifully!

Gideon and his crew are awesome! Quick to respond, organized, and pricing is very reasonable! Communication was top notch! Couldn't ask for a better excavation company. Highly recommended!

On time, on budget! Gideon cut about 800 feet of new road for our property including 3 culvert's and was on point with his time/cost estimate to the day/dollar. Overall cost estimate wise, the only material additions were ones that I added or could not be foreseen. I am extremely happy with his work and will hire him again in the future.

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!!

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.

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!
