"He was very easy to work with. He saw the vision of what was needed and did it to perfection. He is very fair with his estimate and stayed with price quoted. Ask several times durning job if it was to our satisfaction and he also did a couple of other things that were not on his list but made the place look better. We are so happy with him that we have ask him to come back after the build and finish off the yard with seeding and whatever else is needed. ."

"Provider was prompt, professional and friendly.  Arrived at the agreed upon time for a free estimate and performed work same-day after we agreed to the price.  He stuck to the price despite taking longer than expected and more work than usual due to worn-rusted pipes in my home.  Cleaned-up after himself and left no sign that work was done other than our new, working toilets.  We are very pleased and reccomend McDonagh & Sons Plumbing & Sewer Inc.

Excavating questions, answered by experts

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.

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.

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).
