|---|---|---|
| 300 sq ft slab | $1,500-$5,000 | Thickness and rebar control breaking time and disposal weight. |
| 800 sq ft crawlspace foundation | $5,000-$15,000 | Perimeter walls and access add excavation time. |
| 1,500 sq ft basement foundation | $15,000-$45,000+ | Basement walls, backfill, and site stabilization widen the range. |
Permit and risk checks
Foundation work may need engineering, erosion control, utility checks, inspection, or grading approval after removal.
How to use this page
Separate structure demolition from foundation demolition in every bid because concrete removal changes equipment, haul weight, and timeline.
Frequently Asked Questions
Is foundation removal included in house demolition?
Sometimes, but many bids exclude it or price it separately. Always confirm slab, crawlspace, or basement scope.
Why is foundation demolition expensive?
Concrete is heavy, reinforced, and often below grade, so breaking, loading, hauling, and backfill add cost.
