Cedar Deck Repairs & Water Management Improvements

This Snohomish home features a cedar deck with cable railing, sweeping mountain views, and a covered outdoor living area below. High Rock Exteriors completed focused repairs to address water intrusion where the deck meets the house, replace affected cedar materials, and improve connections in the existing railing.

We carefully opened the repair area from above and below, removing deck boards along the house and temporarily taking down the affected under-deck drainage panels and gutter. This provided access to inspect the exposed wall and repair the siding and flashing details. We replaced sections of tongue-and-groove cedar siding and installed galvanized flashing and sealant at the affected transitions to help direct water away from the wall.

Along the upper deck, we installed replacement cedar decking where we had removed the decking for the flashing repair. We also adjusted and secured the cedar top rails on the existing cable railing to improve their connections at the posts. Once the repairs were complete, we reinstalled the drainage panels and gutter beneath the deck.

The project preserved the home’s natural cedar appearance while addressing localized repair needs. The new wood was left unfinished for the homeowner to stain to complement the existing deck and siding.
