Questions this calculator answers
- How do I compare foundation repair quotes?
- Check scope before price: same diagnosis, method, unit count and depth. Then compare price per unit. This tool does the arithmetic on your figures.
- Why are my foundation quotes so different?
- Usually because they price different scopes: different pier counts, depths or methods. Ask each firm what they measured and why.
- Should I take the cheapest bid?
- Only if it prices the same work with the same warranty. A lower total on fewer piers or an open depth can cost more later.
- Do I have time to cancel after signing?
- For many sales made at your home, the FTC Cooling-Off Rule gives three business days to cancel. State rules can add more.
