What this calculator estimates
Estimate a foundation repair budget from crack work, piers, waterproofing, engineering, permits and contingency.
How to use it
Enter Crack repair length (linear ft); Crack repair cost per linear ft ($); Number of piers or supports; Installed cost per pier ($); Drainage and waterproofing ($); Engineering and inspection ($); Permits and other work ($); Contingency (%). Select Calculate to update the results.
How the calculation works
Crack repair is estimated by length, pier work by unit count, and waterproofing, engineering and permits are added before contingency.
Worked example: starting scenario
| Crack repair length (linear ft) | 40 |
|---|---|
| Crack repair cost per linear ft ($) | 45 |
| Number of piers or supports | 8 |
| Installed cost per pier ($) | 1800 |
| Drainage and waterproofing ($) | 6500 |
| Engineering and inspection ($) | 2200 |
| Permits and other work ($) | 800 |
| Contingency (%) | 15 |
| Estimated foundation repair cost | $29,555.00 |
|---|---|
| Crack repairs | $1,800.00 |
| Piers and supports | $14,400.00 |
| Waterproofing, engineering and permits | $9,500.00 |
| Contingency | $3,855.00 |
Important limitations
Foundation movement requires professional diagnosis. Soil, structure, access, stabilization method and hidden damage can make actual costs much higher or lower.
