Foundation piering costs $1,000 to $3,000 per pier installed at our October 2026 index, with a typical figure near $1,800. A typical job uses several piers, so the invoice can land in the five figures. Crack sealing and waterproofing are cheaper, but they treat the symptom: the diagnosis decides which repair is the right one.

What makes one job cost more than another?

Price driver 1The diagnosis, not the methodA widening crack, a sloping floor and a sticking door point at different causes. The repair follows the diagnosis, and an engineer report is cheaper than the wrong repair.
Price driver 2Number of piersPiers are priced per pier, so the count is the biggest line. Depth and soil conditions change the count and the price.
Price driver 3AccessA pier under a finished basement or behind landscaping costs more to reach than one at an open foundation wall.
Price driver 4DrainageWater is behind most foundation movement. Fixing grading, gutters and downspouts belongs in the same conversation as the piers.

Why do the published guides disagree?

Foundation guides disagree because the repair method changes the price. Piering, crack sealing and waterproofing solve different problems, and a quote for one is not comparable with a quote for another. Ask what the diagnosis is before comparing the totals.

Permits, engineers and warnings

Structural repair usually needs a permit, and many jurisdictions require an engineer's design for underpinning. Ask who the engineer is and whether the report is included before you sign. Stop and get advice if a crack is wider than about 6 mm, one side of a crack is higher than the other, or a door has started to stick with no other explanation.

A worked example

A five-pier job at the typical rate is about $9,000 before drainage or interior repair. Piers are priced each, so the count is the line to check: ask how many, how deep and why that number. A quote that names a total without a pier count is hard to compare with anything.

How to lower the cost without cutting corners

  • Fix water first. Grading, gutters and downspouts are cheaper than piers and often part of the cause.
  • Get one engineer report and use it for three quotes, so everyone prices the same diagnosis.
  • Ask for a pier count and depth, then compare like for like.
  • Do the interior access work yourself where it is safe, such as moving storage.
  • Check whether the warranty is transferable; it affects resale value.

How the price changes by region

Soil and climate decide most of the local difference. Expansive clay soils move more with moisture, and cold climates add frost depth to the design. Coastal areas add corrosion protection for steel piers. Two identical houses in different soil conditions can need different repairs.

Questions

How much does foundation repair cost?

Piering runs about $1,000 to $3,000 per pier installed at our October 2026 index, typical $1,800. A job usually uses several piers, so the total is often five figures.

Do I need an engineer?

For a widening crack, a sloping floor or underpinning, yes. An engineer report is usually required for the permit and is cheaper than repairing the wrong thing.

Is piering always the answer?

No. Water management, drainage and crack sealing solve some problems. The diagnosis decides. A contractor who sells piers before diagnosing is a warning sign.

Does insurance cover foundation repair?

Often not, because policies usually exclude settlement and earth movement. Sudden events such as a burst pipe are treated differently. Ask the insurer before assuming.

How long does foundation repair last?

A properly designed pier system is meant to be permanent, with a warranty. The warranty terms matter more than the headline number.

Can I just seal the crack?

Sealing is right for a stable cosmetic crack. If the crack is widening, uneven or the floor slopes, sealing hides the symptom. Get a diagnosis first.

How long does foundation repair take?

Pier jobs are often a few days on site, plus curing and inspection. The schedule depends on the pier count, access and permits.
