Project guide
Hiring foundations contractors in Colorado
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.

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.
Common projects
- Monolithic and slab-on-grade foundations for houses, garages and shops
- Crawl space and full basement foundations with footings, walls, drainage and waterproofing
- Pier, grade beam, helical and drilled pier foundations, plus foundation repair and underpinning
What affects a quote
- Foundation type, footprint, wall height and the rebar and concrete volume the plans call for
- Excavation depth, soil bearing capacity, groundwater and any over-excavation or engineered fill
- Formwork, pumping, waterproofing, footing drains, anchor bolts and backfill
Foundations FAQ
What does foundations work cost?
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.
What should I share when requesting a foundations estimate?
Send the stamped structural plans, the soil report, the survey with corner stakes and elevations, the truck access route, and the framing start date the foundation has to be ready for.
What can change the cost of foundations work in Colorado?
The main cost items are foundation type, footprint, wall height and the rebar and concrete volume the plans call for; excavation depth, soil bearing capacity, groundwater and any over-excavation or engineered fill; formwork, pumping, waterproofing, footing drains, anchor bolts and backfill. A site visit helps the crew see which ones apply.
Do foundations projects in Colorado need permits?
Foundation work is always covered by the building permit, and the footing inspection has to pass before any concrete is placed. Many jurisdictions also require a foundation survey or as-built before framing to confirm setbacks, and engineered systems need the engineer's letter of observation.
