Under Decking Drainage System Installation in Maryland

You probably know that adding a deck is a great way to beautify and add livable space to your home. It is also an excellent investment, with an average 81% return on the cost of the project. What many homeowners do not know is that an under decking drainage system will increase the usable space your deck provides, adding even more value to your home.

What Is an Under Deck Drain System and How Does it Work?

Under decking drainage catches rainwater and snowmelt that seeps down between deck boards. The water is diverted away from the space underneath, leaving it dry.

The installation consists of mounting deck drainage panels to the bottom of the joists that support the decking above. The panels catch the runoff and are sloped so that the water flows away from the space below. Typically, they are made of lightweight, durable, and non-rusting materials like aluminum.

When installed by the professional team at Diamond Decks & Home Improvement, under decking drainage adds functionality and beauty to your existing deck or new deck project.

Benefits of Installing a Deck Drainage System

Increased Living Space

Under decking drainage systems are sometimes known as deck ceilings. There is a simple reason for this. When the drainage system is installed on an overhead, second story deck, the panels become the ceiling for the space below the decking.

Entertaining on a patio or enjoying a garden area below the deck is no longer subject to the elements. Runoff water is diverted away from patio furnishings and your guests.

By increasing the usable living space in your home, the deck drainage system adds value. It also enhances the quality of the space as the drainage panels, or ceilings, come in a variety of colors and finishes to complement your patio décor and landscaping.

Increased Storage Space

If your deck is at the first-floor level and decking is thirty or more inches above the ground, a decking drainage system offers a way to increase storage space. Using the same technique, the drainage panels are installed on the underside of your deck and water is diverted from the space below.

The result is a dry, safe place to store tools, equipment, children’s toys, and anything else you might want to keep out of the elements. The additional storage space also adds value to your home.

William remained in close communication with us until the job was completed and we were satisfied. The deck itself is beautiful and of excellent quality. We will be recommending Diamond Decks to everyone we know. -Kev Mitchell, Piney Orchard, MD"

  • "Just wanted to express our thanks to Diamond Decks for a job well done. Our deck is absolutely beautiful, and is just how we envisioned. The crew that worked on our project had an obvious attention to detail. Min is a master of his trade, and he and the other guy (sorry, didn't get his name) worked their tails off to get the project done on time. We did have a little issue where we had to have some of the existing framing replaced, which added to the cost of the deck. But that was not anyone's fault, and Buddy was very clear to begin with that once the old decking was removed there could be some issues (which there clearly was). Over all Diamond was comparable to two other bids we received, and Buddy was sensitive to keeping the cost down, but still factored superb quality materials (Fiberon) in the price. The project was started ahead of schedule, and was completed on time. All in all, my wife and I would highly recommend Diamond, if quality at a reasonable cost is the goal. (I've learned years ago, cheapest is never the best). Hats off to Diamond Decks. Sincerely, Bruce and Susan Gaesser (Ellicott City)"

  • "Diamond Decks was great! We used Diamond Decks to tear down an old deck and replace it with a new deck w/decking underneath while we were selling my mom's house. William Zinnert helped us with the proper paperwork for our HOA and pulled the permit for Howard County. They started the project when they said they would. They followed our suggestion of which side of the house to go around. The guys on the job were punctual, respectful and efficient. They did not cut any corners. They passed all inspections with Howard County. They cleaned up after the job was finished. William Zinnert was available at all times for questions. I highly recommend Diamond Decks for your next project. Katie Randolph"

The manager in charge was helpful in getting the necessary paper work and approval to build the deck.He also gave us very good recommendations on the size of the deck, and giving us options on the steps vs. a larger deck. He was very pleasant to deal with. "

  • "The recent service call to replace some deck planks that were discolored went effortlessly for us. I had planned to move the deck furniture and potted plants away from the affected area but they beat me to it by coming earlier than expected. They even put everything back! Couldn't be more satisfied. "
