Customers say: Quick response

"I really appreciated the great excavation and fill work that Roland Gagnon did for me. This was a driveway drainage project that required low spot filling and proper grading of the area. The driveway now has the proper slope and is draining properly. Roland went above and beyond my expectations, he will be my first call for any future work."

Excavating questions, answered by experts

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

Yes, professional installations include trenching or borehole drilling required for ground loops.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

To drill a shallow well, you may be able to use a drive well point. This is a tapered point that is driven into the ground. A drill bit at the end of PVC pipe may be another option to consider. A lot of the cost depends on what tools are available near you.

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).
