We loved our experience with Rhino! Communication was quick and clear. We were able to get a no hassle estimate and scheduling with the team was easy. They were able to get out to our house quickly and did great landscaping work!

We hired Rhino to do our front and backyard. My husband and I are really happy with how it turned out. The yard looks great now and the kids love having a place to play and hang out.

Denis did a great job and was very conscientious about the details. The weather was horrible, but he came out regardless and braved it like a trooper. Pricing was more than fair and I will definitely be using them again.

FAQ
Common questions about yard drainage
Why does my yard hold water or stay soggy?
Usually a mix of flat grade, heavy clay soil, and water with nowhere to go. We find the source and build a path that moves it off the area for good.
What is the difference between a French drain and a catch basin?
A French drain is perforated pipe in gravel that collects groundwater along its whole length. A catch basin is a box that collects surface water at one low spot. Many yards need both, and we often combine them.
Where does the water actually go?
To a safe discharge point: daylight on a lower part of the property, a dry well, or an approved connection, depending on your lot. We confirm this before we dig.
Can you tie in my downspouts?
Yes. We connect downspouts into buried pipe and carry roof water away from the foundation instead of letting it dump right next to the house.
Will a drainage system help a wet crawl space or foundation?
Often, yes. Moving surface and groundwater away from the foundation is one of the best ways to keep water out of a crawl space. If there is an interior or structural water issue, we will tell you when a specialist should also take a look.
How long does a drainage project take?
Most residential drainage jobs take one to a few days depending on the length of pipe, the number of drains, access, and weather. We give you a clear timeline with your quote.
