"During a house purchase US Trenchless came out and scoped the main sewer line.  They gave me a detailed report.  They also gave me a quote to replace the line.  After doing some comparison shopping US Trenchless beat a competitors low bid by 10%.  The work was done on time and professionally.  I would recommend them and use them again.  Ross and Tim were great."

"Matt did an excellent work and I am very happy! It’s been at least two weeks and no issue from my water heater - no leaks. He was very responsive and he cleaned his work. It is not easy to find someone who can do both in replacing the damaged walls and installing the water heater. I hesitated at first how much he was charging for it was very affordable. It wasn’t a scam and he did an excellent work."

"Had an old fence that has been leaning for a while that I have been putting off for too long. Reached out to H&S to come out for an estimate. He responded fast and his quote was definitely within my budget! Let’s just say I love my new fence and couldn’t be happier with the work."

Excavating questions, answered by experts

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

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.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

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.
