Basement Gurus dug out and installed a new underground drain line for our down spouts. It was inconvenient to mow/edge around the down spout. Our neighbors have maple trees, and they always have the whirly birds/ buds /leaves clogging the downspout. With the access plug, it made it much easier to clean out the pipe. Thank you, Basement Gurus!

Professional, efficient crew. Solved a water issue by redirecting my downspout and running it underground. Can't even tell my grass was dug up.

After getting an estimate from another company, Basement Gurus offered us a much better system for a much lower price. We had a large and complicated job to do, and the crew finished it all beautifully. Since then, we’ve had several tropical storms, and not a drop of water in the house.

Josh came by to give me a free estimate and he was very knowledgable, and professional. Multiple contractors in Lancaster County have told me how good of a job he does and I was happy to have him in my home. He doesn't offer the cheapest prices but he is not the most expensive either. He offers a battery operated pump, he will take care of any permits that you need, and you pay for quality products. He does a lot of the work himself and he commits to bringing you quality work.
