Basement
$1025-$1813
Use this when the home has a basement or lowest-level slab that supports a standard sub-slab suction system.
Slab-on-Grade
$963-$1688
Slab homes can price differently when finished space, routing, or core drilling complicates the system path.
Crawl Space
$1550-$2800
Crawl-space jobs can move higher when vapor-barrier sealing, access, and sub-membrane suction add labor.
