DIY Under Deck Gutter System: Easy & Effective

Are you tired of wet basements or damaged foundations due to increased water flow from your roof? An under deck gutter system might just be the DIY solution you need. It not only collects rainwater efficiently but also directs it away from your home's foundation, preventing costly damage. Let's dive into the world of under deck gutter systems and guide you through the installation process.

Before we begin, it's crucial to understand that while this project is DIY-friendly, it requires a bit of carpentry and plumbing skills. Also, ensure you have the necessary tools and materials, including a tape measure, circular saw, drill, caulk gun, and quality under decking materials like Everlast 500 or TREXsigned RainProof.

Planning Your Under Deck Gutter System

This step is crucial as it sets the foundation for your entire project. Measure the length and width of your deck, then calculate the amount of material you'll need. Also, determine the placement of your gutters and downspouts, ensuring they align with your home's existing gutter system.

Next, sketch a detailed plan of your under deck gutter system. Include the location of support beams, joist hangers, and any necessary cuts. Having a clear plan ensures a smooth and efficient installation process.

Gathering Materials and Tools

A comprehensive list of materials and tools includes timber Composites (like Everlast 500 or Platinum decking), joist hangers, screws, sealant, and your chosen gutter system. As for tools, you'll need a circular saw, drill, caulk gun, tape measure, and a level.

Ensure you have all the necessary safety equipment too, including durable work gloves, safety glasses, and a hard hat for protecting against falling debris.

Installing the Deck Framework

Begin by installing the framework for your under deck system. Start with the outer edges, ensuring they're perfectly square. Use joist hangers to attach the joists to the band boards, spacing them 16" on center.

Cut out sections for the gangrene beam that will support the gutters. Install the gangrene beam with joist hangers, ensuring it's level and securely attached. Caulk any seams to prevent water from leaking through.

Installing the Gutter System

Now that your framework is in place, it's time to install the actual gutter system. Begin by installing the main gutter channels that run parallel to the deck joists. Ensure they're level and securely fastened to the gangrene beam using gutter brackets.

Next, install the gutter reducers and drop outlets that will connect your under deck gutters to your home's existing gutter system. Seal any connections using a gutter sealant to prevent leaks.

Installing the Gutter End Caps and Downspouts

Once your main gutter channels are installed, install the end caps to seal off the ends of the gutters. Next, install the downspouts, ensuring they're securely fastened to the deck framework and spaced appropriately.

Use a downspout extension to direct water away from your home's foundation. Install the downspout extension, ensuring it's level and securely fastened to the downspout and the ground. You may also want to consider installing a splash block or gravel pit to further redirect water away from your home.

Finishing Touches

After your gutter system is installed, it's time to finish off your under deck space. Install privacy screening, lights, or even furniture to create a cozy outdoor space.

Regularly maintain your under deck gutter system by cleaning out debris and inspecting for any leaks or damage. This will ensure the longevity of your system and prevent costly repairs.

Embrace the satisfaction of a job well done as you sit back and enjoy your beautifully-functional under deck space, knowing that you've not only upgraded your home but also protected it from water damage.
