"Jason was very easy to work with and provided suggestions for seeding and subsequent treatment due to the terrain and soil. There were a number of unanticipated stumps in the area which caused a lot of roots to be eliminated after the fact. I still have not got to the point where I should mow the new growth which has been a slow process. Jason did a nice job on the excavation part and he did all the work maintaining previous drainage contours put in years ago.He was flexible, knew his business, and easy to work with and adjust aspects of the job."

Excavating FAQs, answered by experts

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.
