What this calculator estimates
Estimate a crawl-space encapsulation project cost from area, liner, labor, drainage, dehumidification, mold treatment, permits and contingency.
How to use it
Enter Crawl-space area (sq ft); Liner and sealing materials per sq ft ($); Labor per sq ft ($); Drainage and sump work ($); Dehumidifier and electrical work ($); Mold treatment and cleanup ($); Permits and inspection ($); Contingency (%). Select Calculate to update the results.
How the calculation works
The calculator totals area-based liner and labor costs, adds drainage, dehumidification, treatment and permit costs, then applies contingency.
Worked example: starting scenario
| Crawl-space area (sq ft) | 1200 |
|---|---|
| Liner and sealing materials per sq ft ($) | 4.5 |

| Drainage and sump work ($) | 2500 |
| Dehumidifier and electrical work ($) | 1500 |
| Mold treatment and cleanup ($) | 800 |
| Permits and inspection ($) | 200 |
| Contingency (%) | 10 |
| Estimated crawl-space encapsulation cost | $14,740.00 |
|---|---|
| Materials and labor | $8,400.00 |
| Drainage, dehumidification and treatment | $5,000.00 |
| Contingency | $1,340.00 |
| Estimated cost per sq ft | $12.28 |
Important limitations
Access, crawl height, water intrusion, structural repairs, mold, insulation removal, local labor, drainage and code requirements can change actual bids.
