"Our project they performed for us was a takedown of an an old existing wood retaining wall and installing a new concrete block wall and steps. Fantastic design and building around 100 feet of wall and steps. They insured that there was proper drainage by installing good drain material behind the wall so no buckling of it could ever occur and good drain outlets were installed. It looks great and we have had many compliments on it and their work. We would not hesitate to call them on other projects we might need."

Excavating questions, answered by experts

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.

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.

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.

Most professional excavation teams will charge between $8 and $15 per cubic yard. Calculate the cost by finding the volume of your pool—width x length x depth—and dividing it by 27. Then, multiply the price by the cubic yards from your equation. Budget for complications like a rocky lawn, hard-to-access pool area, or high local labor prices.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.
