Under-Deck Drainage & Dry Space Systems

Smart Solutions for Every Deck

An uncovered lower patio or storage space doesn’t have to stay damp or unused. With the right under-deck drainage setup, you can turn that forgotten area into a clean, dry place for gatherings, furniture, or gear. Around Knoxville, where sudden summer storms roll through fast, it’s one of the most practical upgrades you can make.

At Riverview Decks, we install systems that collect and redirect water before it ever reaches the ground level. The result is a dry space that feels finished, not forgotten. Our team of 36 craftsmen and women has completed hundreds of projects across East Tennessee, each designed to stand up to our changing weather and rolling terrain.

Nate and his team at Lakeview were great to work with. He was very quick and responsive to the needs we needed completed. We had some general repairs done to the house and had them back out again for our laundry room remodel.

We had a difficult situation that was left from previous owners but he had all the answers and great suggestions on what to do that we never even thought off. Definitely recommend Nate and his team at Lakeview Home Improvement.

I cannot speak enough about the professionalism of this company and everyone associated with it. All steps in the project were well laid out in a portal, and although my deck is small and simple when compared with other jobs, I was treated as a valued client every step of the way. This business is a first class operation.
