"Had a great experience with Chris Kuper at Basement Detective! My basement flooded from non-stop storms and I needed a sump pump installed along with complete renovation of my basement. They were very competitive in pricing and outstanding in results. Chris even helped coordinate with the contractor doing my basement renovation after the sump was installed to make sure none of the drainage was disturbed by the new work being done. I have since weathered at least 3 large storms and can hear the sump working as needed. Very happy with the results!"

We are a full service basement, crawl space and foundation repair contractor. Rated A+ by the Better Business Bureau we have repaired over 40,000 homes and structures in Virginia, West Virginia, Tennessee, and North Carolina over the past 40 years. We are fully insured and licensed. Angie's List members receive a free consultation and inspection. We have worked in all types of locations, including residential and commercial locations, government agencies, colleges, hospitals, churches, and condo associations. We provide a lifetime transferable warranty, carry a Class A Contractor's License and we're fully insured.

"Should be called "Steal-tite". Company came out to give estimate in MAY 2019. Said they couldn't do the job until December, but we weren't having any leaks by June, so we went ahead and signed contract, sent in $800 deposit. Well, we ended up buying another house and decided not to have the work done. This was about October. Tried to call Seal-tite several times, always get the "answering service" and they never call back. Finally found the card of the engineer who quoted our estimate, Curt Giantonio. He said too bad so sad for our deposit, and that we had no recourse to get the money back. I realize the contract said the deposit was non-refundable. But the company could have been courteous, understood the situation, and refund my deposit even though legally they don't have to. Instead they've chosen to keep my money for zero services rendered. I could understand them keeping a portion to cover the travel costs of the engineer who came on site to give the estimate, but there's no way that is anywhere near $800. Greedy company that obviously doesn't care about people."

Excavating questions, answered by experts

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

In most areas, you will need a permit for excavation work, even if the project only involves grading or yard leveling. Excavation permits help protect the topography in your area and can avoid issues with poor drainage. In most cases, your excavation company will know whether or not permits are required and will even pull them and close them out for you before and after the job. You can also verify whether permits are necessary by calling your local building department and explaining the proposed project.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

There is no standard depth, but typically, septic tanks are buried between 4 inches and 4 feet underneath the earth’s surface. There are a few factors that will determine your tank’s depth, including the height of your bedrock, the distance between your home and the tank, and the depth of your main sewer line.

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.
