"Bob & Larry did a great job going beyond what I needed. I am very happy with their work. Nothing was left behind. They may be a smaller company but cannot be beat for customer service, price and quality of work. I plan to use them again in the Spring when I will be removing a deck."

"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 Gary Gaston to clear my severely overgrown backyard. He showed up when he said he would to look at the job and give me a bid. I decided to go with Gaston Brothers and we set up a day and time to start the project. Gary said he could do it in one day. Again he showed up on time and started the work. I was impressed at Gary's skill operating the backhoe. That is truly a lost art. He cleared enough to fill 2 full sized dump trucks. Gary went the extra mile by leveling out the yard. It's ready for me to rake it smooth and plant grass. Thank you Gary!"

"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

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

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.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

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.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.
