## FAQ
**Q: What is seismic retrofitting and why is it important for Portland homes?**
A: Seismic retrofitting is the process of strengthening a home's foundation to better withstand earthquake forces. In Portland, where we are overdue for a major earthquake along the Cascadia Subduction Zone, retrofitting is crucial. It helps prevent your house from being forced off its foundation, minimizing damage and allowing you to safely shelter-in-place after a seismic event.

**Q: How much does a typical seismic retrofit cost with NW Seismic?**
A: While costs vary depending on the size, construction type, and finishes of your home, most of our seismic retrofits range from $3,500 to $6,000. This investment can provide peace of mind, knowing that your home is better protected against earthquake damage and that you'll be able to shelter in place.

**Q: What does NW Seismic do to ensure a proper earthquake retrofit?**
A: We follow earthquake retrofit science, including performing a full assessment of your home and a calculation called the Base Shear Formula. This helps us determine how to correctly anchor your house to its foundation and shift loads to the strongest components, ensuring that your house stays put during an earthquake.

**Q: Why is it important to have my home's foundation inspected before buying?**
A: Having a foundation inspection before purchasing a home is crucial for assessing its structural integrity and identifying potential weaknesses. We can evaluate the foundation's quality and provide a quote for a seismic retrofit, giving you a clear understanding of the home's earthquake resilience before you buy.

**Q: What areas of Portland does NW Seismic service?**
A: NW Seismic proudly serves the entire Portland, Oregon metro area. We're dedicated to providing affordable seismic retrofitting solutions to protect as many families as possible from the potential devastation of a major earthquake in the Cascadia Subduction Zone.

**Q: My home was built before 1974. Does it need seismic retrofitting?**
A: Yes, homes built before 1974 in Oregon were not required to be anchored to their foundations, making them particularly vulnerable to earthquake damage. Anchoring is the most important thing you can do to prevent a collapse of your home. We can assess your home and provide a customized retrofit solution.
