"Jared was awesome he totally delivered everything he quoted and then some!!! His pricing was fair and as questions came up during the construction phase he expertly problem, solved and offered reasonable solutions. I would highly recommended DAGS excavation For a wide variety of projects.

"Konnaugh and his team were a pleasure to work with. They showed up on time, and after demolishing and removing a hot tub and a chicken coop, they left my yard practically spotless! They did such a great job, I would highly recommend them to anyone looking for junk removal or yard cleanup ??"

""ABSOLUTELY SUPERB" - Ken and Rowen were contracted to install Round River Rock Stone along approximately 180 feet (both sides) of my driveway. Ken promptly answered my request for an estimate. The next day he arrived to view the job and was very thorough about understanding my expectations for the project, He offered advice and is very knowledgeable about how to do top quality work. After my reviewing other estimates my decision was to go with McAdams Excavating, Ken and Rowen arrived as promised and quickly began meticulous work. Material was excavated to provided a 3 inch depth of stone, landscape fabric was installed, finally the stone. The duo were meticulous in all facets of this project and it looks absolutely gorgeous! Do not hesitate to hire this company!!!"

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

FAQs for excavation major grading or resloping projects in Merrimack, NH

You can excavate in winter, but frozen soil slows down the process and increases labor costs. Many grading companies offer discounted rates during their off-season, so ask for a winter quote and weigh the savings against a longer timeline. A brief conversation with a local professional will help determine whether cold-weather excavation is suitable for your site.

Foundation digs can be completed in as little as three days or take up to three weeks. Soil density, access, weather, and hidden obstacles all play a role, so every timeline is a bit different. Have your contractor walk the site and flag any potential issues early—clear expectations help keep both the schedule and budget on track.

You must always call 811 before excavating. Dial 811 a few days in advance so that utility crews can mark underground lines and ensure the area is safe for digging. Hitting a buried cable or gas pipe can be both dangerous and expensive, and many municipalities will not issue permits unless the site is flagged correctly.

To remove soil during an excavation project, your crew will load the spoil into dump trucks with a backhoe or excavator, haul it to a disposal site, and return for the next load. Efficient hauling keeps the work zone clear and the project moving. Depending on the site and volume of osil, multiple trucks may rotate to maintain a steady flow.
