Foundations contractors cost and hiring guide

Hiring foundations contractors

Foundation contractors build the part of the structure that carries everything above it into the ground: spread footings below frost depth, stem walls or basement walls, monolithic and slab-on-grade foundations, and pier or grade beam systems where soils are poor. The work follows the stamped plans and the geotechnical report, and it is inspected at fixed points, usually the open footing trench with rebar in place before the pour, then again before the slab and before backfill. Frost depth sets the footing bottom, from about twelve inches in the Gulf states to four feet or more across the northern tier. Waterproofing or dampproofing, a footing drain and free-draining backfill are what keep a basement dry, and they are cheapest to do right while the wall is still exposed.

Listed businesses are based in Vevay, Elberta, Lebanon, Webster, Salmon, Dixon, though most crews travel well beyond their home city.

What foundations work costs

Slab-on-grade foundations typically run $6 to $14 per square foot of footprint, crawl spaces $8 to $20, and full basements $30 to $100 or more depending on depth, wall height and waterproofing. A foundation for a typical 2,000 square foot house therefore ranges from roughly $12,000 for a simple slab to $60,000 or more for a basement in a cold climate.

Ranges are national and approximate; regional labor rates, material prices and site conditions move them in both directions.
