We repair foundations and retrofit homes for seismic resilience with practical scope decisions based on condition, risk, and code requirements. This service covers cripple wall bracing, foundation bolting, and structural reinforcement.

Our Foundation & Seismic Approach

Protect what holds up the house.

Portland sits in the Cascadia Subduction Zone. Older homes built before modern seismic codes often lack foundation bolting, cripple wall bracing, and adequate connections between framing and foundation. We assess what your home actually needs and build a scope that addresses real risk.

Every retrofit gets an engineering review, a defined permit path, and phased execution with inspections at each milestone. No guesswork on what goes under the house.
