When you’re ready to finish your basement, it’s exciting to think about the possibilities: extra living space, a home theater, or even a guest suite.
But many homeowners run into trouble when they hire a contractor who isn’t fully prepared to handle the unique challenges of basement remodeling. Hidden moisture issues, building code requirements, and poor planning can turn a dream project into a costly mistake.
At Custom Built Design & Remodeling, we’ve guided Michigan families through basement transformations for 15+ years. We understand the hurdles you face, and we know the right questions to ask can make all the difference in protecting your investment.
To help you feel confident in your decision, here are the top 10 questions you should ask any contractor before hiring them for your basement finishing project:
- Are you licensed and insured?
- What experience do you have with basement finishing specifically?
- Can you provide references from past clients?
- How do you handle moisture and waterproofing issues?
- How will you ensure the project meets building codes?
- What’s included in your estimate?
- Who will be managing the project on-site?
- What is your timeline for completion?
- What kind of warranty do you offer?
- How do you handle unexpected issues or changes?

1. Are you licensed and insured?
A reputable contractor should hold the proper licensing and carry insurance for both liability and workers’ compensation. This protects you from being financially responsible for accidents or damages that occur during your project.
Why It Matters
- Ensures you’re working with a professional who meets state requirements
- Protects you financially from accidents or property damage
- Builds trust and accountability with your contractor
Bonus Tip
Ask for copies of their license and insurance certificates and confirm they’re current.
2. What experience do you have with basement finishing specifically?
Basements come with unique challenges like moisture control, egress windows, and code compliance. You’ll want a contractor who has specific experience with these details, not just general remodeling.
Why It Matters
- Specialized experience means fewer surprises during construction
- Contractors familiar with basements know how to prevent mold and water issues
- Helps ensure a smoother project timeline
Bonus Tip
Request to see photos or case studies of their past basement projects.
3. Can you provide references from past clients?
Talking with previous clients gives you a clear picture of the contractor’s quality of work and professionalism.
Why It Matters
- Firsthand feedback helps you avoid hiring the wrong contractor
- Reveals how the company communicates and handles challenges
- Gives you peace of mind knowing others had a good experience
Bonus Tip
Ask past clients what they wish they had known before starting their basement project.
4. How do you handle moisture and waterproofing issues?

Basements are prone to water damage, so a contractor must address moisture problems before finishing work begins.
Why It Matters
- Prevents costly future repairs due to water leaks or mold
- Ensures your investment lasts long-term
- Protects your family’s health by reducing mold risk
Bonus Tip
Have your contractor explain their process for checking foundation cracks, drainage, and vapor barriers.
5. How will you ensure the project meets building codes?
Every finished basement must follow local building codes, including egress windows, ceiling height, and electrical standards.
Why It Matters
- Keeps your project legal and up to code
- Protects your resale value when you sell your home
- Ensures safety for your family and guests
Bonus Tip
Ask how your contractor stays updated on local building code changes.
6. What’s included in your estimate?
A detailed estimate helps you understand what’s covered (and what isn’t) so there are no surprises later.
Why It Matters
- Helps you budget accurately for your project
- Prevents hidden fees or unexpected costs
- Builds transparency and trust
Bonus Tip
Ask for a written estimate that breaks down labor and materials.
7. Who will be managing the project on-site?
Knowing who your day-to-day contact will be helps ensure smooth communication throughout the project.
Why It Matters
- Keeps you informed about progress and changes
- Reduces the chance of miscommunication
- Gives you a point person for questions or concerns
Bonus Tip
Request weekly project updates from the manager to stay in the loop.
8. What is your timeline for completion?
Understanding the timeline upfront helps set realistic expectations for your family.
Why It Matters
- Allows you to plan around disruptions in your home
- Keeps the contractor accountable for deadlines
- Helps you understand what could delay the project
Bonus Tip
Ask for a written schedule with milestones so you can track progress.
9. What kind of warranty do you offer?
A warranty shows the contractor stands behind their work and materials.
Why It Matters
- Protects your investment in case of issues after completion
- Gives you confidence in the quality of work
- Demonstrates the contractor’s commitment to customer satisfaction
Bonus Tip
Ask whether the warranty covers labor, materials, or both, and for how long.
10. How do you handle unexpected issues or changes?
Remodeling projects often come with surprises. It’s important to know how your contractor will handle them.
Why It Matters
- Prepares you for potential budget or timeline adjustments
- Shows you how flexible and transparent the contractor will be
- Reduces stress when problems arise
Bonus Tip
Request that all changes or unexpected costs be put in writing before work continues.
