What raises or lowers the price
| Factor | Why it matters |
|---|---|
| Foundation type | A single open basement slab is simplest. Crawl spaces need a sealed liner, and mixed foundations may need more than one suction point. |
| Finished space | Routing pipe through finished walls or closets takes more labor than an unfinished basement. |
| Pipe route | An interior route through the attic is often tidier; an exterior route can be quicker. Your contractor will suggest options. |
| Soil under the slab | Tight clay or rock can make it harder to draw air and may call for a stronger fan. |
| Existing passive pipe | If your home was built with a passive pipe, adding a fan can cost less than a full system. |
| Sealing work | Sump covers and crack sealing are usually included but vary by house. |
