Ready Your Home for Seismic Activity with TerraFirma

Retrofitting Process

Give TerraFirma a call and schedule a free inspection today


Scheduling a free inspection with your local TerraFirma System Design Specialist is the first step toward a permanent fix for your home's earthquake readiness. Your System Design Specialist will conduct an on-site evaluation of your home.

Depending on several factors a prescriptive seismic retrofit or a custom engineered system will be designed to bring your home up to standard. TerraFirma takes care of all necessary engineering, permits, labor, and materials.

On the big day, you can expect a well-prepared expert production crew that has a detailed plan for your specific project. The foreman will lead the crew through the process and serve as a resource to answer any questions.

When the repair work is complete, your foreman will do a thorough final inspection with you. We always ask our clients to leave us a review on Google, Yelp, the BBB, Angie's List, or Facebook and refer TerraFirma to friends and family who are experiencing problems with their foundations, basements, or crawl spaces.

TerraFirma's award-winning service and products are backed by extensive warranties that are fully transferable. In the unlikely event that you have a follow-up repair issue, we are here to help. If your solution required a sump pump, drainage system, or anything else that needs upkeep, you may benefit from regular maintenance with the TerraFirma Service Department.
