Foundation Piering Cost in 2026

By the HomePriceFacts Research Team · Last updated: November 11, 2026 · Prices checked against published 2026 foundation piering cost data

Foundation piering costs $1,000 to $3,000 per pier — the one figure five published sources agree on — with most underpinning jobs landing at $10,000 to $30,000 and Angi's national average at $25,000. But this is the least-audited price in home services: no industry body, state agency or academic study publishes audited foundation repair pricing, the only big-brand piering page is about 580 days stale, and two duplicated spam domains sit in the exact-match top five. This guide prices each pier type from the sources that agree, shows job totals by pier count, and flags every spread the sources themselves cannot settle.

Start with what the job actually is, because the vocabulary is half the confusion. Piering — also called underpinning in every major cost guide — means driving steel, concrete or helical piers under a settled foundation down to stable soil or bedrock, then lifting and levelling the settled section onto them. The price is quoted per pier, and the pier count is set by the length of settled wall: piers are typically spaced every 5–8 feet (HomeGuide), and a typical job needs about 10 piers (Angi) or 7–10 (Today's Homeowner). Multiply the per-pier price by the pier count and you have the job — which is why the per-pier figure matters more than any national average. A quote for 6 piers and a quote for 14 piers are not two prices for the same job, even on the same street.

The second thing to know is how thin the evidence is. FoundationSelect, a compilation that documents the topic's pricing problem in unusual detail, states flatly: "No industry body, state agency or academic study publishes audited foundation repair pricing. Every figure below comes from either a home-services cost publisher, a lead-generation site, or a repair company." It also records that helical-pier pricing has "the widest disagreement of any method" — $1,500–$4,400 across sources — and refuses to reprint city-level figures because the two lead-generation sites publishing them "contradict each other by a factor of five in places." That is the honest starting point for this guide: the $1,000–$3,000 per-pier band is solid; almost everything else is a range with a reason behind it, and the reasons are listed below.

What the price normally includes

• The piers themselves — materials plus driving and installation, priced per pier by type (see the table below)
• Excavation and access work around the foundation, and lifting/levelling the settled section onto the piers
• Labour — about 80% of an underpinning job's cost on Angi's figures ($8,000–$24,000), at contractor rates of $100–$200 an hour; This Old House and HomeAdvisor both put the hourly rate at about $200
• NOT usually included: a structural engineer inspection ($340–$780, HomeAdvisor; $500–$1,000, This Old House) or a full geotechnical soil report ($1,000–$5,000, HomeGuide); permits ($75–$150 per Fixr, This Old House and HomeGuide — but $200–$1,000 per Angi, so budget the higher end until confirmed); landscaping restoration, interior crack repair, or drainage add-ons such as French drains ($2,000–$6,000, Today's Homeowner)

Piering cost by pier type (per pier)

Two rows deserve a note. First, concrete: Angi's ~$1,000 and Today's Homeowner's $2,000–$3,000 do not agree, and the gap is unresolved in the published sources — Angi is the fresher source (October 2026 against April 2025), so it leads, but a quote at the higher band is not automatically a bad quote. Second, helical: Angi's ~$3,000, HomeGuide's $2,000–$4,000 with a ~$3,000 typical, and Today's Homeowner's $2,500–$3,500 all bracket the same point, which makes helical the best-corroborated per-type figure in the topic. Segmented and spot piers rest on Today's Homeowner alone and are labelled as such. No major publisher prices "slab piers" as a distinct type — do not accept a quote that invents one; use the generic $1,000–$3,000 band. And one caution on independence: This Old House states its foundation figures are "based on cost data from Angi", so its $1,000–$3,000 per-pier band is the same dataset as Angi's, not a second vote.

Job totals by pier count

HomeGuide's helical table is the only published count-based breakdown, and the typical residential helical job is 5–10 piers. For underpinning generally, HomeGuide's own pages disagree with each other — its methods table says $10,000–$20,000 while its text says $10,000–$30,000 or more — and its standalone underpinning page (about 715 days old) prices 1 pier at $1,000–$3,000, 2–4 piers at $2,000–$12,000, 5–8 piers at $6,000–$25,000 and 8–10+ piers at $10,000–$30,000+. Today's Homeowner puts the typical job at $7,000–$30,000 with an average of about $16,000, at 7–10 piers — lower than Angi's $25,000 average, and the difference is partly its April 2025 date. For a settling or sinking foundation specifically, HomeAdvisor prices the job at $5,000–$25,000 and Fixr at $4,500–$25,000 — the two agree, and both are lower than a full underpinning job because not every settling foundation needs piers. If your quote is for a full foundation replacement instead, the comparison is $50,000–$100,000 (Angi) or $20,000–$100,000 (HomeGuide).

What drives the price up or down

Pier type

The table above is the driver: concrete at about $1,000 a pier, steel or push at about $2,000, helical at about $3,000 (Angi). Helical piers cost more because they are screwed into the ground with a hydraulic drive and can be installed in tighter spaces and deeper soil; concrete piers are the cheapest where the soil and access allow them. The type is not a free choice — it is set by soil, depth and load, which is why the engineer's report comes first.

Depth

Helical piers typically run 10–30 feet deep, and up to 100+ feet in bad soil (HomeGuide); Angi puts push piers to bedrock at usually under 40 feet and helical at about 20 feet. Extra depth costs $20–$25 or more per pier-foot beyond the standard depth (HomeGuide, single source). Depth is the reason two houses on the same street can hold quotes thousands apart: the pier goes until it hits load-bearing soil, and nobody knows how deep that is until the first pier goes in.

Soil type

Expansive clay — the soil behind most Texas and Midwest settling — means harder excavation, more piers and a higher bill; sandy soil is easier and cheaper (Angi, This Old House). No source puts a dollar figure on soil type alone, because soil is priced through depth and pier count rather than as a line item. If your quote mentions clay, expect the top of the per-pier band.

Access

Landscaping, trees, patios and tight side yards force hand-digging, and hand-dug piers cost $200–$500 extra per pier (HomeGuide). Angi and This Old House both flag limited access as a labour multiplier. Clear the work area before the crew arrives — it is the cheapest cost reduction in the whole job.

Foundation type

Pier-and-beam is the cheapest to underpin because the crawl space gives access; slab, basement and crawl-space foundations cost more because of excavation (Angi). Fixr prices foundation repair by type at $1,000–$10,000 for slab, $2,000–$15,000 for pier-and-beam, $2,500–$12,000 for crawl space and $2,500–$25,000 for basement — those are whole-repair ranges, not piering prices, but they show the same ordering. Our basement finishing guide prices the work that usually follows a foundation fix, and it assumes the structure is stable first.

Permits and engineering — the spread to budget for

This is where the sources openly disagree, and the honest move is to budget the high end. Permits: $75–$150 according to Fixr, This Old House and HomeGuide's foundation guide — but $200–$1,000 on Angi's underpinning page, and $600–$3,600 on HomeGuide's helical page. Engineering: a structural engineer inspection at $340–$780 (HomeAdvisor) or $500–$1,000 (This Old House), against a full geotechnical soil report at $1,000–$5,000 (HomeGuide) or $500–$3,000 for the soil report alone (This Old House). An inspection and a soil report are different products — ask the engineer which one your quote includes before comparing prices. Our concrete driveway guide covers the other concrete job most piering customers price in the same year, and our sewer line guide prices the underground work that often shares the same excavation.

Piering vs underpinning — same job, two names

In the major cost guides, piering and underpinning are synonyms: "piering or underpinning", "underpinning, also called piering". The only distinct comparison is traditional mass concrete underpinning, which pours concrete sections under the footing instead of driving piers. No two independent sources publish a per-section price for mass concrete, so this guide does not quote one — a single thin source puts it at $1,000–$3,000 per section, and a single Bay Area contractor at $2,500–$5,000 per pin, and neither clears the two-source gate. When a contractor says "underpinning", ask which method and which pier type the quote covers, and get the answer in writing before the pier count is set.

Why the sources disagree so much

Three reasons, all verifiable. First, the data is old: Today's Homeowner's piering page carries a 2026 title but was last updated April 9, 2025 — about 580 days before this guide was written — and its helical-piers sibling is about 538 days old. Second, the top of the search results is polluted: two duplicated spam domains carry word-for-word identical "Best Foundation Repair Contractors" articles reposting the same Angi and Forbes figures, and the long tail is thin lead-generation sites republishing 2022–2023 pricing as 2026. Third, the guides contradict themselves: HomeGuide's methods table says underpinning is $10,000–$20,000 while its own text says $10,000–$30,000+, and This Old House's figures are Angi's figures restated. The $1,000–$3,000 per-pier band survives all of that because five sources publish it independently. Everything else on this page is labelled with its source and its date, so you can see which numbers are fresh and which are not.

Ways to keep the cost down

• Get the engineer's report first — it decides pier type and count, and a $340–$780 inspection (HomeAdvisor) that prevents over-piering pays for itself.
• Fix the water first: gutters and downspouts ($1,000–$2,500, Today's Homeowner) and French drains ($2,000–$6,000) stop the soil movement that caused the settling — piers without drainage treat the symptom.
• Compare quotes per pier, not per job — same pier count, same pier type, same scope, or the totals are not comparable.
• Ask in writing whether permits and the engineer report are included: the permit spread alone runs $75 to $1,000 depending on the source.
• Clear access before the crew arrives — hand-dug piers cost $200–$500 extra per pier (HomeGuide), and a clear work area is free.
• Do not pay for piers you do not need: piers spaced every 5–8 feet (HomeGuide) is the check, and a second opinion is cheap against a $25,000 average job.
