General Contractor

Built for Renton's Older Homes

Many Renton homes were built between the 1970s and 1990s, and some older Highlands and Central Renton houses predate that. Walk-in shower installation and bathroom remodeling in these homes often mean updating aging plumbing and subfloors before new tile goes in. We plan that prep work into the scope from the start.

Renton's lots vary widely, from valley-floor parcels near The Landing to hillside and Highlands lots with tighter access. Roof replacement and roof inspection on these properties depend on pitch, decking condition, and how easily crews can stage materials. We assess those conditions before quoting.

Basement finishing in Renton often involves older foundations and moisture control, so we check drainage and waterproofing before framing. Kitchen and cabinet installation scopes also account for the layouts common to split-level and post-war homes in the area.
