Questions to Ask Before Hiring a Retrofit Contractor

Retrofit work can involve the foundation, framing, connections, cripple walls, anchors, roof-to-wall ties, or other parts of the house. The right scope depends on the home, local conditions, and an on-site assessment by a qualified professional. That is why asking careful questions matters more than choosing the fastest or cheapest bid.

A good contractor should be able to explain the work in plain language, tell you what they know, and be honest about what they still need to inspect. If answers are vague, rushed, or hard to get in writing, that is useful information before you commit.

This is especially important if you are comparing earthquake-related work with wind or storm upgrades. The questions are similar, but the details may differ by region and home type. If you are still learning the basics, start with the broader guides or read our hurricane and wind retrofit guide.

Try to compare bids for the same general scope. If one contractor includes permits, debris removal, and hardware upgrades, while another only lists labor, the lower price may not be the better value. Ask each company to break out what is included and what is not.

It also helps to meet at least two or three contractors at the property if possible. A photo-only estimate can be useful as a starting point, but many retrofit decisions depend on access, existing damage, foundation type, crawlspace conditions, and what is visible during the visit.

Use a simple checklist when you compare:

• Are they licensed for this type of work?
• Are bond and insurance current?
• Did they inspect the property in person?
• Is the scope described in writing?
• Are permit responsibilities clear?
• Are payment terms and change orders clear?

If you want introductions to local companies that handle this type of work, you can get matched, free. You still choose who to speak with and who to hire.

Start with the basics: Are you licensed, bonded, and insured for this work? Then ask for the full business name and license number so you can verify it yourself with your state's licensing board. Also ask whether the company carries general liability insurance and workers' compensation coverage.

Helpful follow-up questions include:

1. What license classification do you hold?
2. Is the license active and in good standing?
3. Do you use employees, subcontractors, or both?
4. If you use subcontractors, are they also properly licensed and insured?
5. Can you send proof of insurance before work starts?

Do not rely only on a business card, truck logo, or verbal promise. Verify the license, bond, and insurance yourself, and make sure the contract shows the same business name you checked. This protects you if there is a dispute about scope, damage, or who was actually responsible for the work.

Not all construction experience is retrofit experience. A contractor may be excellent at remodels but do far fewer seismic or wind-related projects. Ask how often they work on homes similar to yours, such as raised foundations, crawlspaces, older wood-frame houses, hillside homes, masonry chimneys, garages under living space, or other common local conditions.

You can ask questions like:

• How many retrofit projects like mine do you complete in a typical year?
• What types of homes do you work on most often?
• What site conditions usually make the project simpler or more complex?
• Who decides the final scope if hidden conditions are found?

If your home may have a soft-story condition or other special layout issue, ask whether they regularly handle that type of work and whether a licensed engineer is typically involved. For example, larger or more complex buildings may require a different process than a small single-family house. Our soft-story retrofit guide explains the issue at a high level, but only an on-site assessment can confirm what applies to your building.

References can help too. Ask for a few recent customers with projects similar in size and type to yours. When you speak with them, ask whether the contractor showed up on time, kept the site clean, explained changes clearly, and finished close to the written scope.

This is where many misunderstandings begin. Ask the contractor: What exactly are you proposing to do, and why? A strong bid should describe the visible conditions they observed, the work they recommend, the materials or hardware they expect to use, and any assumptions behind the price.

Useful questions include:

1. What did you inspect, and were there any areas you could not access?
2. What work are you recommending, and what is the purpose of each part?
3. What is included in the price, and what is excluded?
4. Are engineering plans expected for this job?
5. What hidden conditions could change the scope later?
6. Will you provide a written bid with line items or clear allowances?

Be careful with very short bids that only say something like "retrofit foundation" without detail. Ask them to clarify disposal, finish repairs, patching, access work, permit fees, engineering fees if needed, and who pays if extra damage is uncovered. If the home might qualify for help paying for eligible work, such as California's Earthquake Brace + Bolt program, ask whether they are familiar with the paperwork and then check whether you qualify through the program rules yourself.

No contractor should tell you from a quick glance online exactly what your house needs. The proper scope depends on the structure and what can be confirmed on site. If you want more than one opinion, that is reasonable.

Ask early: Will this project need a permit, and who will handle it? Permit rules vary by city and county, and whether a permit is needed depends on the job and location. A contractor can explain their process, but if you want extra certainty, you can also confirm with your local building department.

You should also ask about schedule in practical terms:

• When could you start?
• How many days will the work likely take?
• Will there be days when no one is on site?
• What hours will crews work?
• Will I need to move items, leave the home, or provide access to a crawlspace or garage?

Communication matters just as much as price. Ask who your main contact will be, how quickly they usually respond, and how updates will be given if conditions change. It helps to get names, phone numbers, and email addresses in writing.

If English is not your first language, ask whether they can communicate in your preferred language or provide key documents in simple written form. Even when everyone is acting in good faith, retrofit terms can be confusing. Clear communication reduces mistakes and makes it easier to compare proposals fairly.

Before signing, ask for all payment terms in writing. The safest approach is a written schedule tied to clear project milestones, not a vague promise that the balance will be sorted out later. Rules on deposits vary by state, so review your local requirements and make sure the contract is complete before money changes hands.

Important questions to ask:

1. What deposit is required, if any?
2. When are progress payments due?
3. What proof will I receive that work tied to each payment is complete?
4. How will change orders be priced and approved?
5. What warranty do you provide on workmanship, and what manufacturer warranties apply to materials?

A change order should be written, priced, and approved before extra work begins whenever possible. That matters in retrofit projects because hidden conditions can appear once walls, crawlspaces, or foundations are opened or cleaned. Ask the contractor to explain common reasons costs change so you are not surprised later.

Finally, keep copies of the contract, permit documents, change orders, invoices, and final receipts. Confirm scope, price, and warranty details in writing, and do not feel rushed. You keep the choice of who to hire.
