"Josh and Zach are fantastic! They can do anything! Building on heavily treed undeveloped acreage. The built the construction road, dug foundation pits, cleared brush, thinned trees, dug trenches for water lines and electric conduit. They work directly with other contractors and county to get specs, handle inspections, ask questions. Very professional, highest quality work, reasonably priced. I have never worked with a better contractor!"

"Norberto and his crew are very professional and knowledgeable about their work. They removed a huge damaged tree for us, to the point of allowing the 6 ft trunk remaining to hopefully revive and regrow in the spring. Well done, and very challenging work. They also installed an intricate and elaborate drainage for a new lawn to replace an existing drainage system put in by another contract which only resulted in a dead lawn that had been overcome with an even worse water problem. Mount Olive turned a muddy mess into a perfectly draining area! We are happy to recommend them for your landscape needs and are very pleased with their work. They are good listeners and clearly strive for happy customers."

"Needed a section of fence replace that had blown down in the storm. This has to be one of the best experiences I've ever had with a contractor. I have ZERO complaints and nothing but praise. They quote was on par with other contractors, but they use treated screws exclusively and offered the wooden posts on a metal pole...these are amazing! They communicated quickly and concisely, their work ethic is impeccable, they cleaned up and removed all the old fence and cement at no additional cost. The fence is beautiful on both sides, the guys were very nice (family business) and I am beyond impressed. They showed up when they said they would, the worked the entire time they were here and cleaned up when they left. In fact, I have another 75 linear feet that I am going to schedule and have done by them. I was going to do it myself, but the end result of their work is so impressive that there is no question I'm going to hire them again. Highly recommended!"

Excavating questions, answered by experts

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

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.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.
