"Dan Gallant of Bear Rock Hardscapes did an excellent job designing & installing a curved walkway made of different colored pavers. The walkway improved the overall impression of my home. When friends saw the walkway, they hired Dan to install a walkway or patio at their houses. I would hire Dan again."

Excavating questions, answered by experts

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.

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.

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

To determine whether your homeowners' insurance will cover crawl space repair, consider the cause of the issue. Repair may be covered if the problems were caused by an event that the insurance covers, such as vandalism or a windstorm. However, companies won't cover the repair if the issues are caused by neglect or wear and tear.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.
