"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!"

"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."

"I built several speculative houses and Scott handle the job from start to finish from clearing the lot, setting the elevation for the new home to downspout systems, backfill, sewer hooks, water service hookups and grading the property ready for landscaping. He also does Right of way work for concrete driveway approaches and sidewalks. Would highly recommend this contractor to my friends and hire him again for any future jobs."

Excavating FAQs, answered by experts

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

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.

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.

Yes, professional installations include trenching or borehole drilling required for ground loops.
