"We thoroughly enjoyed working with this company for our turf repair project. They got us in weeks ahead of schedule as they knew time was an issue for our busy daycare. They came up with a plan to fix the seams and clumping issues in our turf that we just had installed by another company. They made the most of a tough project and were able to provide us with a playground surface our littles will be able to use for years to come. The guys are fun to work with and Dawn is a problem solver. I can’t recommend them enough."

"I used Diamond D to clear some land in Lakeport. Made a contact through HomeAdvisor. Tyler was super responsive, worked with me to define our needs and provided a clear bid. Both Tyler and Megan were very professional and communicated well with me since I live a few hundred miles away. I will use them again, it was a very good experience."

Excavating questions, answered by experts

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

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.

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

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.
