Professional Earthquake Retrofit Services

The Cascadia Subduction Zone is a real concern for Oregon homes. Our retrofit work helps keep your home better anchored during seismic activity by improving key structural connections.
Why Earthquake Retrofitting is Critical
Portland Seismic Risk
Many homes built before modern seismic standards are not properly anchored to their foundations. Without bolting and bracing, these homes can be more vulnerable to shifting, sliding, or structural damage during an earthquake.
Earthquake retrofitting is often a good fit for older homes, especially those with crawl spaces or cripple walls, or structures that were not bolted to the foundation.
Earthquake retrofit Portland OR services are essential for:
- Homes built before 1978 (pre-seismic building codes)
- Houses with crawl spaces or cripple walls
- Structures not bolted to their foundations
- Properties in Portland, Lake Oswego, Wilsonville, and surrounding areas
Our Seismic Strengthening Solutions
- Foundation Bolting Services
Foundation bolting secures the sill plate to the concrete foundation using steel anchor bolts. This helps reduce the risk of lateral movement during an earthquake and improves the home’s connection to the foundation.
- Cripple Wall Bracing
Cripple walls can be vulnerable during seismic events. We reinforce these walls with structural plywood sheathing and proper framing connections to improve strength and stability.
- Crawl Space Retrofit
For homes with crawl spaces, we combine bolting and bracing with structural tie-downs where needed. When appropriate, we also address basic crawl space conditions so the retrofit work performs as intended.
- Shear Wall Installation
Shear walls help resist lateral movement during earthquakes. We install engineered sheathing and structural connections designed to distribute seismic forces and improve stability.
- Water Heater and Appliance Anchoring
Unsecured water heaters and appliances can tip during earthquakes, creating safety hazards. We strap and anchor key items to help reduce the risk of leaks and damage.
- Automatic Gas Shutoff Valves
Automatic gas shutoff valves can help reduce fire risk by stopping gas flow when significant seismic activity is detected.
- Mudsill Repair and Replacement
If the sill plate is deteriorated, bolting alone may not be effective. We repair or replace damaged wood as needed, then complete foundation bolting to support reliable seismic reinforcement.
How We Perform Earthquake Retrofits

You receive a clear retrofit plan and a detailed estimate so you understand the recommended work and the cost before anything begins.
- Foundation Bolting Installation
We install anchor bolts at proper spacing based on the structure and applicable requirements to improve the connection between the home and foundation.
- Crawl Space Reinforcement
When crawl space retrofits are needed, we install the bracing and reinforcement required for better seismic performance, with attention to access, airflow, and long-term conditions.
- Final Inspection and Documentation
After the work is complete, we perform a final review and provide documentation for your records.
- Cripple Wall Reinforcement
We install structural plywood sheathing and blocking to brace cripple walls. This seismic strengthening helps reduce collapse risk and protects your home’s structural integrity.
