I highly recommend Robert Mastroni Excavating for excavation, grading, drainage, and property work. I had a massive tree stump burried in the middle of my front yard that needed to be removed, and the entire area needed to be regraded and leveled afterward. This was a substantial job, and they did an amazing job from start to finish. In addition to removing the tree stump and completing the excavation work, they regraded my front yard and installed a drainage system to redirect runoff from my gutters. They clearly knew what they were doing when it came to proper grading, drainage, and managing water runoff. They were professional, reliable, knowledgeable, efficient, super communicative, and incredibly easy to work with. Robert was extremely flexible and accommodating as my needs changed throughout the project. They were able to take care of the additional work and finish everything off with a beautiful new front masonry walkway. I really appreciated having one company that could handle so many different aspects of the project and make sure everything came together properly. The transformation of my front yard is incredible! If you're looking for a dependable excavation contractor in the Monroe/Fairfield County area for tree stump removal, excavation, yard grading or regrading, drainage installation, land clearing, walkway installation, or other property improvements, I would absolutely recommend Robert Mastroni Excavating. I'm extremely happy with the quality of the work and the final result and would definitely use them again.
Bob has been doing my gravel driveway since 1985. And he did a large excavating project years ago. He is always professional does a great job and it's fairly priced.
We recently hired Bob for a major residential grading and landscaping project covering both our front and back yards. The results are outstanding — we couldn’t be happier with how it turned out. What really stood out was Bob’s flexibility and professionalism. The scope of the project changed significantly as it evolved, and he was extremely accommodating, offering thoughtful design ideas along the way. His background as an engineer was a huge advantage, especially in designing and constructing the drainage and retaining structures. We highly recommend Bob to anyone looking for a skilled, reliable, and creative contractor.
