Cost examples by project size
| Project size | Scope | Estimated range | Cost note |
|---|---|---|---|
| 300 sq ft basement | Small finished area | $1,200-$4,500 | Access through stairs can slow debris removal. |
| 600 sq ft basement | Typical finished basement | $2,400-$9,000 | Walls, ceiling, flooring, and fixtures add up. |
| 1,000 sq ft basement | Large finished basement | $4,000-$15,000+ | Moisture damage or old materials may require testing. |
