"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

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

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.

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.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.

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.
