In a 2024 review, a customer said MacKinnon & Sons Excavating had installed a sewer line at their house before they bought it. When it turned out the line ran on the neighbor's property without an easement, that 2024 customer said the company moved the line and made it right, though it was not their mistake, standing by work done for a different owner. The company describes itself on its website as offering excavation to residential and commercial clients, from driveways and septic systems to paving a road, and says it has 20 years in business. Its stated service area includes Lebanon, Sanford, York, Wells, Berwick, Dover, Rochester and Somersworth. A 2025 customer praised Nick, Billy and the entire crew for the work and the reasonable prices. In a 2023 review, a customer said the company responded immediately to a request for a quote, with competitive pricing. Its Google profile shows 4.8 stars from 21 ratings.
Nick, Billy and the entire crew are awesome!!!! Great work! Reasonable prices and awesome results. Highly recommend them. Can not say enough good things about them.
I highly suggest calling MacKinnon and Sons. They installed a sewer line at my house prior to my purchase. After the purchase, it was determined the city of Dover and prior owner okayed the line running on my neighbors property without an easement from the neighbor. Although it wasn’t their mistake, but was their work, they took it upon themselves to move the line and make it right. Couldn’t be more impressed by a company. They stood by their work, even when done for a different owner. Really appreciate this company and will be using them for any future evocation needs.
Grew up with Nick and Bill, couldn't ask for 2 people individuals. I've trusted them since 2nd grade and would trust them on any home or property project. He will soon be coming to my land for work!
Immediate response when reaching out for a quote, with competitive pricing and excellent results you cant go wrong with this company!!
