Deck Drainage Systems in Monroe, Snohomish County & Surrounding Areas

Make More Use of the Space Beneath Your Deck

An elevated deck can provide outdoor living space above and below. An under-deck drainage system collects rain passing between the deck boards and redirects it, creating a drier area for seating, entertaining, or outdoor storage.

High Rock Exteriors installs TimberTech DrySpace and Trex RainEscape in Monroe, throughout Snohomish County, and surrounding areas, helping you choose the system that suits your deck and plans for the space underneath.

TimberTech DrySpace

DrySpace collects water beneath the decking using panels attached to the joists. The panels provide a finished underside and direct water toward a planned gutter and outlet.

It is a practical option for many existing elevated decks because it can often be installed without removing the decking. It can also be incorporated into new construction.

We evaluate joist spacing, beams, clearance, drainage slope, and access before recommending installation. Because water reaches the framing before collection, proper framing protection remains important.

Trex RainEscape

RainEscape installs above the joists and below the decking, collecting water before it reaches the framing underneath.

It is especially useful during a new build or resurface, when the framing is accessible from above. Existing decking must be removed for installation.

RainEscape also allows a separate finished ceiling below, with lighting or fans planned where suitable. Ceiling finishes and electrical work are additional parts of the project scope.

Which System Fits Your Project?

DrySpace is often worth considering when you want drainage beneath an existing deck while keeping the current boards.

RainEscape is worth comparing when building new or replacing the decking, particularly when protecting the framing below the drainage layer is a priority.

Both require careful attention to gutters, discharge locations, wall details, and future maintenance. Neither system alone creates an enclosed, weatherproof room or prevents all wind-driven rain.
