Dirt Dynamix LLC says on its website that it has been in business for four years, and it names Merrimack as its service area. A recent Google customer says Josh and his folks did a professional, prompt job on a driveway resurface and repair, and that the company also does their winter plowing. A 2025 customer wrote that Dirt Dynamix was more expensive than the other excavation companies they looked at, and still said they made the right choice for a fairly large project in their back yard. That 2025 customer said Josh Dupuis kept them informed at each step, adapted to several unforeseen obstacles, and charged exactly the price they had agreed to. A 2025 reviewer wrote that their driveway from the builder was so narrow in front of the garage it took a three-point turn to get in, and that Josh and Tanner at Dirt Dynamix had a very fair quote. A 2024 customer said the company did a culvert replacement, and that Josh offered to help them find a paving company. A 2024 reviewer wrote that Josh chipped several large trees in their yard and leveled new yard areas with sand. A 2024 customer described a large-scale job where they were there early, stayed late and cleaned up after themselves. A 2024 customer said the job was quoted, scheduled and finished within 3 weeks of first contact.
Josh and his folks just did a fantastic, professional, prompt job on my driveway resurface/repair. Also do my winter plowing....Highly recommend!!
Dirt Dynamix was more expensive than the other excavation companies we were looking at, but we were very impressed with his vision for our yard and his ideas for the solution we were seeking and, all things considered, we definitely feel like we made the right choice and would absolutely make the same choice again. Josh Dupuis and his team were fantastic from start to finish. Josh was very friendly, knowledgeable, and professional. He also had a excellent feel for what we were trying to accomplish at each stage of what, for us, was a fairly large project in our back yard. He kept us informed at each step of the project and let us know immediately if there were any concerns. In addition to that Josh adapted to and dealt extremely well with several unforeseen obstacles (that definitely were not his fault) that presented themselves as the project progressed. Without fail, whether things went as expected or had gone astray, Josh always handled the situation with both fervor and professionalism. Each time we felt that Josh had gone way more than the extra mile to be sure that we would be happy with the result. In the end, the price was exactly what we had agreed to and the result in our yard is nothing short of amazing. I highly recommend Dirt Dynamix for excavation work.
Dirt Dynamix was great. Professional and on time as promised. The work was far better than we expected. I would highly recommend them for any work you need done. One year later and the work is holding up perfectly, just like day 1.
Our driveway from the builder was so narrow in front of the garage you had to do a three point turn to get in. After 14 years we did something about it! Josh and Tanner at Dirt Dynamix had a very fair quote, and were true professionals. Amazing work. I highly recommend. Some pictures show what it will look like in a year when we pave it!
As a business owner, I value professionalism and the peace of mind knowing that they will get the job done quickly, efficiently and that they will solve problems for me. DDX met and exceeded my expectations on all accounts! They responded quickly, we put together a game plan immediately and the solved my problem with no headaches for a reasonable price! Will 100% use them again!
