Under Deck Drainage & Ceiling Systems in Atlanta

Drainage panels or ceiling panels mount between the joists underneath your deck. When rain falls through the gaps between deck boards, these panels catch the water and channel it along a slight slope toward a gutter at the deck's edge. The gutter connects to downspouts that carry the water away from your foundation. The result is a completely dry area below your deck — no dripping, no puddles, no mud.

Yes — and that's how most of our projects work. We install the drainage panels or ceiling system from below, attaching everything to the existing joists. We don't need to remove or disturb your deck boards. The only requirement is enough clearance underneath to work (typically at least 7-8 feet of headroom for a usable living space). We assess your deck during the free estimate.

These systems typically cost $8-$20 per square foot installed. A basic trough-style drainage panel system for a 300 sq ft area runs about $2,400-$4,500. A finished ceiling panel system with integrated gutters and optional lighting costs $4,500-$6,000+ for the same area. The investment pays for itself by creating usable outdoor living space you'd otherwise lose to rain.

Drainage panels (trough-style) are individual channels that mount between joists to catch and redirect water. They're more affordable and get the job done, but the joists remain visible from below. Ceiling systems are full panels that create a smooth, finished ceiling under your deck — similar to a porch ceiling. They look better, hide the framing completely, and are easier to clean. Both keep the space below 100% dry.

A full ceiling system does reduce airflow under the deck compared to an open underside. We account for this by ensuring the system has proper drainage slope so water doesn't pool, and by leaving strategic ventilation gaps where needed. In Atlanta's humidity, maintaining some air movement is important to prevent mildew on the deck framing above the panels. We design every installation to balance dry space below with healthy airflow for the structure.
