"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

Errors in site preparation can lead to structural failures or appear costly midway. Professionals ensure detailed, reliable home base development layouts.

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.

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.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

A joint utility trench, or joint trench, is a long, buried ditch on a property that contains two or more utility lines rather than running the lines in multiple trenches. Some utilities, like gas and electric or electric and communication lines, are better suited to joint trenching, while others, like water and sewer, are not allowed to be in the same trench.
