"John and Cory installed a two level granite rock wall, granite steps and brick walkway to our front door, and it looks fantastic. We were impressed with their hard work and attention to detail. Particularly valuable to us was his background in this type of work which let him recommended design and arrangement ideas for us to consider, and which made the completed project better than we could imagine on our own. John made at least three visits to view the site, discuss options and sent pictures of similar projects. This assured we agreed on what would be done up front so there were no surprises. During the project he daily described what he was doing and the next steps. The granite blocks for the wall were carefully placed for the right look by individually hand splitting, sawing, or grinding for a custom fit. There was extensive work behind the wall to back-fill with stone and even anchor the large end posts with rebar to allow good drainage and stability. This type of detail is impressive since it is all out of sight behind the front blocks and will never be seen, but it will help assure the wall lasts for a long time to come. The same type of attention was given to the positioning, leveling, base preparation and placement of the brick walkway. The project was finished off with a layer of dirt/loam to allow plantings around the hardscape. John and Cory were easy to work with and stuck to the original estimate. Any potential changes were discussed and an estimate provided so we could decide whether or not to include the change. We are 100% satisfied with the outcome of this project. John F."

"Frank was great. Had him here to excavate for a shed and he did an excellent job. He was reasonably priced, knowledgeable, and friendly. Also dug conduit for electrical for it. Awesome guy and would love to work with him again."

"When our existing water tank started to falter we knew we needed to upgrade. Derry Plumbing and Heating installed a phenomenal tankless system for our 3800+ sq foot home and we never had a reason to complain. Our energy costs went down and we always had hot water for our family of 5 and numerous guests."

"We hired Christian to remove tree stumps on our property. He gave us a price the next day and started work within a week. His work ethic is incredible—he left the site spotless and communicated clearly every step of the way. Since then, he’s regraded our driveway, removed an old chicken coop, and cleared brush. It’s safe to say Christian is our go-to contractor now."

Excavating questions, answered by experts

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

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 rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.
