Our landscape enhancement services are designed to leave a lasting impression on clients and visitors alike.


In our excavation division, we specialize in stormwater construction by creating efficient drainage solutions tailored to the unique needs of each property. From excavating and shaping swales to redirect surface water away from buildings and landscapes, to installing catch basins strategically positioned to capture runoff and prevent flooding, we cover a wide range of stormwater management needs. Our expertise extends to downspout burial, seamlessly integrating gutter systems with underground drainage networks to safely convey rainwater away from structures. GroundHog Contractors is dedicated to ensuring comprehensive stormwater management solutions that minimize erosion, protect property integrity, and promote environmental sustainability. With our commitment to quality craftsmanship and attention to detail, you can rely on us to deliver reliable and effective stormwater construction services for both residential and commercial properties.

I wanted to take a moment to absolutely endorse Groundhog Contractors LLC and the work they did clearing out our incredibly overgrown alleyway (and destumping some incredibly stubborn bushes!) as well as some pretty intense excavation activities (digging well beyond what we thought was possible in a yard full of tree roots and clay soil!) I randomly saw a post by one of the owners, Nate Madalinski, and decided to reach out - and Im so happy I did!

They were consistent and timely with their communications, professional, showed up when they said they would and worked extremely hard the whole time they were here and did a great job cleaning up when they left!  Quote was BEYOND reasonable and I’d absolutely call them back for future projects.  Definitely check them out if you have any future yard projects!
