The John Trombley Difference
We're high-demand excavation contractors, and it shows. Not a day goes by that we're not moving earth, digging trenches or prepping ground for the next build — and that volume is exactly why we know the finer points of the work better than most.
Family owned and operated, we've helped with projects of every kind, from new home builds to commercial site work and everything in between. We hold to the standards of the trade and look after the customer at every step.
Why Proper Excavation Matters
Everything you build sits on the work that happens first. Cut corners on grading, drainage or compaction and the problems show up later as settling, standing water and cracked foundations — the expensive kind of hindsight.
What you get with us
- Level, stable ground: graded and compacted to spec
- Water where it belongs: proper drainage and slope
- The right equipment: matched to the job, not forced to fit
- On schedule: excavation sets the pace and we keep it moving

We had John fill an old cellar hole and put in a new driveway at our camp property in Benson Vt. They were on time and came when scheduled. My husband and I are extremely happy with the end result. They were so easy to work with and very clean and neat. I highly recommend this business to anyone, we will be scheduling with them again later in the year for other duties to be preformed at our camp property. We are so very happy. Thank you again and again
Brenda Bowen Benson, VT · 7 reviewsWe were in a pinch for someone to cut down a dead tree and driveway build up as new mobile home was to be delivered at our property on July 31. Contacted them on July 25th and they looked at the job on July 26. They moved some other work around and delivered the driveway material on July 28th and spread everything out on July 29th. July 30th they cut the tree and it all worked out perfectly for our new mobile home delivery of July 31st. They were fast and professional and we could not be happier in the end.

Jholai Pschorr 1 reviewReached out to John for a load of sand I needed to level an area. Within an hour, the sand was delivered! Will be using them again in the future for other projects. I appreciated how respectful and fast they were!
