Here are some of the most common questions we hear.

How Do I Prepare For An Excavation Contractor?

A. Do what you can to make the area accessible as possible. If that’s beyond your capabilities, make sure you let the excavating company know ahead of time what obstacles they may face. You should also move anything on the property that will be in the way, if at all possible.

Q. Should Utilities Be Marked Before The Excavation Contractor Comes?

A. We handle calling Dig Safe to mark out the utilities. Any private utilities (dog fences, private electric lines, etc.) should be marked by the homeowner if possible. Communicate with your excavation company ahead of time to determine who will arrange having the utilities marked.

Q. What Are Some Signs I Need a New Septic System?

A. Some red flags are worse than others. For instance, you may just have slow drains, but you may also have sewage backing up into your home. Look for bright green grass near the septic tank, smell for bad odor, and listen for gurgling sounds. When in doubt, call in a pro to do an assessment.

Q. Do I Need a Retaining Wall?

A. Aside from enhancing the visual aesthetics of your yard, retaining walls can serve a number of purposes. The purpose is to hold back, or retain, soil and that’s most commonly doe to either manage water runoff or provide usable land. It can also be used for preventing soil erosion.
