Foundation Repair Cost Calculator & Price Guide

Foundation repair covers everything from sealing a hairline crack to lifting and leveling a house. The price depends on what is wrong, how much of the foundation is affected, and which repair method fits the cause. A small crack and a sinking corner are very different jobs, even though both get called foundation problems.

Prices below come from published guides and carry a check date of Oct 11, 2026. Because the repair method drives the bill, the tables break costs out by method, by foundation type, and by pier.

Each method solves a different problem. Crack filling and sealing address water and surface damage. Mudjacking and piering address a slab or footing that has settled. Reinforcement strengthens walls that are bowing or cracking under pressure. Lifting and leveling is the most involved and sits at the top of the range.

The reinforcement row is priced for a set of 12 strips, so a longer wall or a second wall raises the total. Always confirm how many strips or piers a quote includes.

Piers, also called underpinning, are driven or set deep below a sinking foundation to carry the load on more stable soil. They are priced one at a time, and most settling problems need several.

A quote with a low per-pier price but a high pier count can cost more than one with fewer, better-placed piers. Ask the contractor to explain how they chose the number and spacing.

The type of foundation changes access, labor, and which repairs are practical.

A basement foundation tops the range because walls can bow inward, leak, or need excavation. Slab foundations are harder to reach from below, which is why mudjacking and piers are common there. Crawl space and pier and beam homes are easier to get under, but beams and posts may need replacing.

• Cause of the problem. Poor drainage, expansive clay soil, plumbing leaks, and tree roots call for different fixes, and the cause may need to be corrected too.
• Extent of damage. A single settled corner costs less than movement along the whole house.
• Repair method. Sealing, jacking, piering, and wall reinforcement are priced differently.
• Foundation type. Slab, crawl space, pier and beam, and basement foundations each have their own access and labor needs.
• Access. Tight crawl spaces, landscaping, decks, and utility lines add time.
• Soil conditions. Soft or shifting soil may need deeper or more piers.
• Related repairs. Drywall, door and window adjustment, brick, and flooring damage from movement are often priced separately.

Foundation work is hard to price without seeing the house. Guides sample different jobs, and one may lean toward minor repairs while another includes larger structural work.

The three sources land in a similar range, which suggests the typical job is a mid-sized repair rather than a full lift. Your own number can sit well outside it, especially for basements or homes with widespread movement.

Some contractors offer a free inspection, but the quote comes from the company that will do the work. An independent report from a structural engineer gives you a diagnosis that is not tied to a sale. It also helps you compare bids on equal terms.

A soil report is separate and mostly matters when settling is tied to soil movement or when a lot of piering is planned.

Look for cracks wider than a hairline, especially stair-step cracks in brick or block, doors and windows that stick or no longer latch, gaps between walls and ceilings, sloping floors, and water in a basement or crawl space. A single symptom is not proof of a structural problem. Many cracks are cosmetic. A professional can tell you which kind you have.

Small, non-structural jobs such as filling a minor crack or fixing a downspout that dumps water near the wall are reasonable for a handy homeowner. Anything involving lifting, piers, or load-bearing walls is a professional job. Mistakes can worsen the movement and affect the whole structure. Many areas require a permit for structural repairs.

• What caused the problem, and does the quote fix the cause or only the symptom?
• How many piers or strips are included, and where will they go?
• Does the price cover permits, engineering, and cleanup?
• What does the warranty cover, and does it transfer if you sell the house?
• Are repairs to interior damage, such as drywall and doors, included?
