"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."

"Overall a good experience. We hired ACS to take down and rebuild a brick pillar supporting our front porch. Gary's crew was excellent. Although they only spoke Spanish they were helpful and did a good job communicating as much as they could about what they were doing and/or had done. We're very happy with the end product. Gary stayed true to his quote and the contract price. The project was more involved than I expected, but they came through and completed it on budget. My only complaint is that Gary was hard to get a hold of at times."

"They did an excellent job. They were on-time, fast and high quality work. Challenging job site with several large trees and massive roots. They moved a huge amount of dirt and did a precise leveling with proper drainage. They prepared the project in one day and poured the next! The stamping process was very interesting and a work of art. Several neighbors have talked to me about having them do work for them. Still getting complements!"

Excavating FAQs, answered by experts

No, fire blight does not survive free in the soil but instead is carried through insects, animals, rain, or wind during the spring. Keep in mind that it can also spread on tools, which is why you should always disinfect them in between cuts.

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.
