"I had a large section of fence that had blown over due to rotting posts. Norberto came out to assess the damage and got back to me the next day with a quote. He was able to man the project the following week and complete the work in 2 days time. Workmanship was excellent and I’m very pleased with the end product. I highly recommend Mount Olive."

"I hired Eric with P4 construction to install a curtain drain in front of my house. He did a great job. He and his guys showed up on time, everything went as planned, and it was finished in the time he said it would be finished. I had A LOT of bids for this project because I needed it to be done right... I live on a hill and had a water problem that needed a real solution, and my neighbor recently had a drain put in that immediately clogged and doesn't work. Eric's plan made the most sense and was in alignment with my research on what I needed. Some of the other contractors wanted to put in a 2' deep drain, but my water problem went deeper (there's a 5' crawlspace under my porch where water was pouring into). He correctly moved the water out to the side of the house, (combined my gutter into it), and all the way down the hill emptying into a flatter area and into a gravel pit."

"Harry and crew did a fabulous job helping design and then building our retaining walls, at an appropriate price. They started exactly when scheduled and finished promptly a week later. Results are fabulous. I absolutely hope to work with them on future projects, and recommend them without reservation."

"Brian and his team did an awesome job of replacing our 30 year old lawn with sod. It looks so much better now than the weeds we had before. He rototilled it then replaced with sod. He gave us tips for how to keep the lawn looking nice. He also cleaned out our garden beds from weeds and blackberry bushes. And added mulch to make it look nice. He added a stone pathway through the side yard to get to the backyard too which looks really nice. He is also looking at rebuilding our privacy fence for us too! We are really happy with Brian’s services."

Excavating FAQs, answered by experts

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

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.
