"Called for a estimate to repair a private rd with two houses on it. He came out in a timely matter and took the time to share what would be the best solution based on his experience. We hired him to build up and grate the driveway/private rd. He showed up during the time frame he said he would and built up and graded the driveway/private rd as well as pitched it so that water wouldnâ t pool. He is just a great guy with a ton of experience to help the customer make the best informed decision. Will use Faulkner for any needs we have in the future hands down."

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

Excavating questions, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

Your contractor should handle dust control during the project. It's best to speak with your contractor beforehand to check if they plan to cover your furniture, protect your vents, or use fans to redirect dust. Eliminating drywall dust is a particularly large challenge during construction, so always take this into account during your planning phase.

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.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.
