Knowing how to choose a seismic retrofit contractor is one of the most important steps you can take to protect your commercial, industrial, or multi-family property from earthquake risk. An experienced contractor can strengthen your building, minimize disruption to tenants, and help keep your project on schedule and within budget.
But not all contractors specialize in seismic retrofitting. Here’s what to look for when choosing a contractor with the experience, expertise, and transparency to deliver a successful project.
5 Pro Tips for Hiring a Seismic Retrofit Contractor
1. Look for Specialized Seismic Retrofit Experience
Seismic retrofitting is a specialized field. Unlike general construction projects, retrofit work requires structural expertise, knowledge of seismic regulations, and experience working in occupied commercial, industrial, and multi-family buildings.
When researching potential contractors, look for:
- Extensive experience with commercial, industrial, or multi-family seismic retrofits
- A proven history of successful projects
- Experienced in-house construction crews for greater quality control and project consistency
- References from projects similar to yours
Many general contractors offer seismic retrofit services, but relatively few specialize in them. Confirm that the contractor has completed projects similar to yours and can provide references.
2. Verify Licensing and Insurance
Seismic retrofits involve structural modifications that must adhere to strict safety regulations. Before hiring a contractor, verify that they have:
- General liability insurance ($10M)
- Workers’ compensation insurance
Unlicensed or underinsured contractors expose you to financial and legal risks if issues arise during the project.
3. Review Pricing and Contract Details
Price matters—but it shouldn’t be the only factor. A low bid may look attractive initially, but change orders, unforeseen conditions, and poor planning can quickly increase the total project cost.
A reputable contractor should provide:
- A detailed cost breakdown with clear line items.
- A clearly defined scope of work outlining exactly what is included.
- Proactive site evaluations to identify potential challenges (e.g., access limitations, mechanical/electrical/plumbing [MEP] interferences, and tenant concerns).
- Transparent communication about possible change orders before the project begins.
At Saunders Seismic, our in-house crews detect and address challenges early, eliminating or significantly reducing costly change orders. This level of foresight ensures a smoother project, prevents unexpected costs, and minimizes disruptions for tenants and businesses.
Focus on Value, Not Just Price
A successful retrofit isn’t measured by the lowest bid—it’s measured by fewer surprises, better planning, reduced risk, and long-term performance.
4. Evaluate Their Approach to Minimizing Tenant Disruption
If your building is occupied, ask prospective contractors how they’ll minimize disruptions during construction. Topics should include work hours, noise and dust control, occupant safety, project phasing, and whether business operations can continue throughout the retrofit.
Contractors should have a clear plan for occupant safety and comply with applicable workplace safety requirements.
Experienced retrofit contractors understand how to complete complex structural work while keeping tenants and businesses operating whenever possible.
5. Check Customer Reviews and Reputation
Customer reviews, referrals, and completed projects provide valuable insight into how a contractor performs.
Ask previous clients:
- Was the project completed on time?
- Did it stay within budget?
- Were change orders handled fairly?
- Was communication clear?
- Were tenant disruptions minimized?
In addition, word-of-mouth recommendations can be just as valuable. Talking to other business owners who have worked with a contractor can help verify their reputation beyond online testimonials.
Understanding how to choose a seismic retrofit contractor means looking beyond price alone. Experience, transparency, communication, and a proven track record all play an important role in the long-term success of your retrofit project.
Red Flags to Watch Out For
Avoid contractors who display the following warning signs:
- Unusually low bids – Often a sign of hidden costs or low-quality work.
- Lack of references or poor reviews – Indicates potential reliability issues.
- Vague or incomplete contracts – Ensure every detail, from scope to costs, is documented.
- Limited experience in seismic retrofits – General contractors without retrofit-specific expertise may cut corners.
- No clear plan for tenant safety, scheduling, or regulatory compliance
