Building a concrete foundation costs a published national average of $9,244, with most homeowners paying $4,012 – $14,755 depending on foundation type, size, and site conditions (Angi; HomeAdvisor publishes the identical figures as Angi’s corporate sibling).1,3 Fixr publishes different national figures: a $12,000 average, with most homeowners paying $6,000 – $42,000, a $5,000 low end, and a $100,000 high end. The two sets of estimates differ and are presented separately throughout this guide.2 Prices are national averages*.
*National averages, not local quotes. Your price depends on the foundation type, home footprint, soil and site conditions, and local labor rates.

What the sources say
| Source | Headline figures | Notes |
|---|---|---|
| Angi (updated Sep 2026) | Average $9,244; most pay $4,012 – $14,755; $5–$37 per sq. ft. | Based on 880 verified projects reported by Angi pros; corporate sibling of HomeAdvisor |
| HomeAdvisor (updated Jun 2026) | Average $9,244; most pay $4,012 – $14,755; project span $1,200–$33,000; $5–$37 per sq. ft. | Figures identical to Angi’s; corporate siblings, and matching figures alone don’t establish independent corroboration |
| Fixr (updated Feb 2026) | Average $12,000; most pay $6,000 – $42,000; span $5,000–$100,000; $5–$35 per sq. ft. (up to $50 for basements) | Separately published, pages state no shared sourcing; estimates differ from Angi/HomeAdvisor and are presented separately |
Cost by foundation type
Angi and HomeAdvisor publish one per-square-foot table by foundation type:1,3
| Foundation type (Angi/HomeAdvisor) | Cost per sq. ft. |
|---|---|
| Monolithic slab | $5 – $16 |
| Stem wall | $6 – $18 |
| Pier and beam | $6 – $12 |
| Crawl space | $6 – $18 |
| Block (cement or cinder) | $9 – $15 |
| Basement | $20 – $37 |
| Walkout basement | $25 – $55 |
| Shed | $5 – $10 |
| Garage | $6 – $12 |
Fixr publishes its own per-square-foot type figures, which differ on several rows and are presented separately rather than merged:2
| Foundation type (Fixr) | Cost per sq. ft. |
|---|---|
| Concrete slab (general) | $4 – $14 |
| Slab-on-grade | $4 – $12 |
| Monolithic slab | $4 – $16 |
| Stem wall slab | $6 – $18 |
| Pier and beam | $6 – $15 |
| Crawl space | $10 – $18 |
| Basement | $20 – $50 |
The stem wall figure of $6 – $18 per sq. ft. appears in both publishers’ tables (separately published figures, and the pages state no shared sourcing). Crawl space and basement figures differ between the publishers, and the tables are not compared row by row.1,2,3
Total cost by foundation type
Angi also prices complete installations by type:1
| Foundation type (Angi) | Total cost |
|---|---|
| Monolithic concrete slab | $5,200 – $13,000 |
| Stem wall | $7,000 – $21,000 |
| Pier and beam | $8,000 – $15,000 |
| Crawl space | About $10,000 on average, up to $20,000 for larger projects |
| Full basement | $24,000 – $50,000 |
| Walkout basement | $37,000 – $101,000 |
| Basement added to an existing home | $38,000 – $148,000 |
| Block foundation | $11,500 – $19,000 |
| Garage foundation | $2,000 – $7,000 |
| Shed foundation (10×16 ft.) | About $1,000 poured concrete; $200–$300 for a gravel pad |
HomeAdvisor publishes the same stem wall, pier and beam, basement, walkout, block, garage, and shed totals (matching sibling figures).3 For pier and beam builds, Angi prices components separately: concrete piers around $1,000, wood beams $1,000 – $3,000, and steel beams $1,500 – $5,000.1
Cost by size
Both publishers scale their per-square-foot ranges across common foundation sizes. Angi applies its $5–$37 per sq. ft. range:1
| Foundation size (Angi) | Total cost |
|---|---|
| 1,000 sq. ft. | $5,000 – $37,000 |
| 1,500 sq. ft. | $7,500 – $55,500 |
| 2,000 sq. ft. | $10,000 – $74,000 |
| 2,500 sq. ft. | $12,500 – $92,500 |
| 3,000 sq. ft. | $15,000 – $111,000 |
Fixr applies its own $5–$35 per sq. ft. range and cautions that its table is based on a home’s typical footprint, which can differ from square footage:2
| Foundation size (Fixr) | Total cost |
|---|---|
| 1,000 sq. ft. | $5,000 – $35,000 |
| 1,500 sq. ft. | $7,500 – $52,500 |
| 2,000 sq. ft. | $10,000 – $70,000 |
| 2,500 sq. ft. | $12,500 – $87,500 |
| 3,000 sq. ft. | $15,000 – $105,000 |
Angi also notes costs of $5,000–$37,000 per 1,000 square feet depending on soil conditions, regional labor rates, and excavation and drainage complexity.1
Labor costs
All three sources put labor at 40%–60% of total foundation cost (Angi and HomeAdvisor are corporate siblings; Fixr publishes separately, and the pages state no shared sourcing).1,2,3 Angi and HomeAdvisor put typical labor spending at $4,500 – $18,500, with rates higher in higher cost-of-living areas, and Fixr notes labor runs higher for crawl space and basement foundations because of the excavation involved.1,2,3
Additional costs to budget for
Preparation and add-on costs published by Angi and HomeAdvisor:1,3
| Item (Angi/HomeAdvisor) | Cost |
|---|---|
| Building permit | $450 – $2,300 (about $1 per sq. ft., per HomeAdvisor) |
| Geotechnical soil test | $1,000 – $5,000 |
| Grading and excavation | $2–$10 per sq. ft. (Angi) |

Pile pricing by material: wood $13 – $20, hollow steel $20 – $40, concrete-filled steel $25 – $45, and concrete $30 – $60 per linear foot.1,3 Fixr separately puts foundation permits at up to $2,300 and basement waterproofing at a $5,000 average.2
For finished basements, Angi lists common add-ons: doors and windows $2,500 – $7,000, plumbing and electrical $3,000 – $9,000, and basement finishing $5,500 – $11,000.1
Repairs down the road
Angi puts foundation repairs at $2,000 – $7,000 on average, with serious structural problems costing more.1 Fixr publishes a $5,200 average for foundation repair.2 See our foundation repair cost guide for a full breakdown.
