Deck building in Renton
HSP Deck Builder in Renton.
Custom deck building for Renton homeowners — mid-century homes in the Highlands, hillside lots in Kennydale, and newer builds near Coulon. Design, permits, and build under one roof.
What we see, what we build, in Renton.
Renton sits at the edge of Lake Washington, with a hillside topography that creates some of the most deck-worthy outdoor spaces in King County. The Kennydale neighborhood is lined with homes on elevated lots above the lake — the kind of hillside positions where a properly engineered composite or cedar deck transforms a backyard into a true outdoor living room. The Highlands and May Creek neighborhoods offer post-war ranches on generous flat lots where ground-level decks and pergola structures work exceptionally well. Renton homeowners who have lived through a few Pacific Northwest winters know the value of building right the first time: proper ledger flashing, drainage-forward framing, and composite or naturally rot-resistant wood that doesn't turn green in year three.
