"When we were having issues with our rentals plumbing, we reach out to Alex and he did not hesitate to come over and find out the issue. Knowing very well we could not do it ourselves, we hired him to get it done. Not only was he courteous and knowledgeable, he was able to fix our backing up problem swiftly. He is very professional, the work he provided fixed our issues in a timely manner and his rate was very resoanable. I highly recommend Cothren Plumbing and construction for any of your needs!"

Excavating questions, answered by experts

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

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.
