"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!"

"All personnel involved were great at their job. From the estimate through the completion, everyone was professional and thorough. What began as removing a concrete drive to allow a plumber access to the sewer main line, became their completing the entire project. This occurred due to the depth of the line. They completed the job quickly, with minimal inconvenience. While they were here, I couldn't have asked for a better experience for a significantly difficult repair."

"I have used McCarty Excavating on a few occasions. Most have been for either clearing areas and building out a site pad for sheds, containers, RV pad, or breaking down an old gravel lot to redo it so it was smooth and usable. Michael has been excellent to work with. He has been on time, friendly and professional. His work has been top tier as well. He was fair on his quotes, communicated very well about problems that arose and made sure I was happy with the end product. McCarty Exc will always be my first call!"

Excavating FAQs, 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.

The cost to drill a well varies, with a national average of around $5,500 for a 150-foot well. However, prices can fluctuate significantly based on several factors, including your location, the required well depth, geological conditions, local regulations, and the specific drilling methods used. For the most accurate cost assessment, it is best to research and get quotes from local well-drilling professionals in your area.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

While general contractors sometimes handle demolition, you can also look specifically for local demolition contractors. Demolition experts need to understand structural integrity, the equipment needed for safe demolition, and the permits required for demolition.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.
