  • "We had Dillon Excavating and Tree Service come out and take down some pesky large dead trees looming over our horse fencing. The guys were professional and super neat. Great communication with Connor the owner! Fair pricing and great quality work. Would 10/10 recommend. We also use them for snow removal in which they are very prompt and thorough."

  • “Connor and his crew did a fantastic job volunteering his time and top-notch equipment to string lights on a 40-foot Christmas tree for the Bridgewater Land Trust. His commitment to our community is outstanding! I am also familiar with his work as a homeowner and highly recommend Dillon Excavating.”

  • “To say that a tree guy can bring joy to a homeowner may sound crazy, however, when that guy is Connor Dillon and has been helping to transform your yard from day one (2 years ago) and just completed the most recent job I gave him in 4 days no less... not crazy at all. This homeowner right here is ecstatic! Amazing job! Connor is professional, efficient, has a great crew, super knowledgeable, and has more than fair pricing. My before and after pictures do no justice to the real thing. Now let the grass grow so I can move on to landscaping!”

    — BRANDY G.

  • “Connor and his crew removed 3 very tall 60ft+ trees all leaning toward my house in a seamless professional manner. They also trimmed tree branches and scrub growth on several other trees. He was very mindful not to tear up my lawn area with his heavy equipment. All areas were cleaned up of wood chips and sawdust. Connor responded timely to all my inquiries and reviewed the scope of the work before starting the project. I highly recommend Dillon Excavating and Tree Service. Thank you, Connor Dillon and crew.”
