What to Ask a Home Addition Contractor Before You Hire
These questions help you separate experienced specialists from generalists who can do the job but aren't the best fit for your project.
- ✓Confirm they work with a licensed structural engineer and can share their network
- ✓Ask about their permit experience in your specific city — timelines vary dramatically
- ✓Verify their experience with exterior cladding that matches your existing home
- ✓Ask how they manage weather delays — additions expose your home to the elements during construction
- ✓Request a detailed project schedule with milestones, not just a completion date
