How Much Does Foundation Piering Cost?

Foundation piering is priced per pier, not per house. Steel and hybrid piers run $600 to $1,000 each installed, so what a piering job costs is your pier count multiplied by that per-pier figure. Two numbers and one multiplication. Every reason one quote reads several thousand dollars under another on the same house traces back to one of those two numbers moving, and the one that moves is almost always the count.

That is also why no company can price your house over the phone. The per-pier figure is knowable before anyone shows up. The count is not, because it comes off a survey of your actual floors.

One scope note before the arithmetic. This page is about piering itself, the underpinning. The whole Texas picture across every repair type, drainage correction and crack work included, lives in the foundation repair cost guide. Repair cost on a pier and beam foundation, which is a different structure rather than a different repair, has its own page, and so does what slab repair runs.

What one pier costs and what moves it

The $600 to $1,000 range covers a pier installed. That means the excavation, the pier driven down to load-bearing strata, the bracket that transfers the weight of the house onto it, the hydraulic work, and the backfill afterward. A pier is not a part you buy off a shelf. It is a hole, a drive, and a load transfer, and labor is most of it.

Four things decide where a given pier sits in that range.

Access. A pier at the front of a house with the truck parked twenty feet away installs faster than the identical pier in a narrow side yard behind a locked gate, where every shovel of spoil gets carried out by hand. Same hardware, more hours.

Depth. Piers go down until the ground stops taking sections, and that point is set by where competent soil sits under your lot. A drive that refuses early and a drive that keeps swallowing sections use the same crew and the same hydraulics, but one runs longer and consumes more pier material. What sets that depth is walked through in how deep foundation piers go.

Interior versus perimeter. A perimeter pier is dug from the yard. An interior pier means either breaking out a section of slab inside the house and patching it afterward, or reaching the spot from outside. Both cost more per pier than working at the edge.

Tunnelling. Where interior support is needed and the floors need to stay intact, a crew tunnels under the slab to reach it. Tunnelling is priced by the foot on top of the piers, it is its own line item on an estimate, and it has its own page in under slab tunneling cost. On some jobs the work gets reached without tunneling at all.

What sets the pier count

The count is the bigger lever, and it does not come from the square footage of your house. It comes from how much of the perimeter actually moved. A 2,400 square foot home with one settled corner takes fewer piers than a 1,200 square foot home with two failing sides.

The survey identifies which wall runs read low and trending. That affected footage gets divided by the standard beam spacing and rounded up, and an affected corner gets support on both intersecting runs. The full derivation, with the spacing rule and worked counts by house size, is in how many piers a house needs.

Two things raise a count above the plain footage math. Two-story sections carry roughly double the load above them and sometimes need tighter spacing. A severe drop occasionally takes an extra pier purely as a lifting point. Neither of those is a sales decision. Both show up on the elevation map, and you should be able to see them there.

A worked example at eight piers

Say your survey comes back with eight piers along one settled side. The arithmetic looks like this.

• Eight piers at the low end of the range, $600 each, is $4,800.
• Eight piers at the high end, $1,000 each, is $8,000.

That spread is the same house and the same eight piers. What separates the two ends is everything in the section above, access, drive depth, and whether any of those eight sit inside the house.

This is an arithmetic example, not a quote. Your house may read as four piers or as fourteen, and the only document that settles it is your own elevation survey. If you want to try the math against your own floor plan, the pier calculator does it interactively.

Why a lump sum with no pier count is not comparable

A quote that gives one number for foundation repair and no pier count has hidden the only variable that matters. Put two of those side by side and you cannot tell whether the cheaper one found less movement, proposed fewer piers for the same movement, or plans to stop short of load-bearing strata.

Ask every bidder for three things in writing. The pier count. The pier locations marked on a plan. The elevation readings those locations came from. With those three, two bids become comparable in a minute, because you are dividing the same arithmetic two ways. Without them you are comparing one sales number to another. What a complete estimate actually contains is laid out in our foundation repair estimate example, and how many to collect is covered in how many estimates you should get.

The cheapest bid usually has the fewest piers

When homeowners bring us three quotes, the low one is rarely the one with a better price per pier. It is almost always the one with the smallest count. That is not automatically wrong, because sometimes the low bidder read the survey correctly and the others padded. But it is a difference in scope rather than a discount, and scope differences get paid for later. Supporting half a moving wall and leaving the rest unsupported tends to crack the house at the seam between them.

The opposite deserves the same scrutiny. A bid that piers an entire perimeter when only the rear reads low is also a scope decision, and it should hold up wall by wall against the elevation map. Ask which reading puts a pier on each wall. A wall that measures level does not need one. The mechanics of what underpinning does and does not accomplish are in foundation underpinning, and the difference between the two pier systems we install is in steel piers vs hybrid piers.

The first number worth getting is a measurement

Price is the second question. The first is how much of your foundation moved, and the answer is sometimes none. About a third of our inspections end with no repair needed, which means that for a real share of the people reading this, the correct cost of piering is zero. Clay here moves with the seasons, and cracks and sticking doors that look alarming often read inside normal range once the floors are measured. If you are still wondering what you are looking at, start with the common signs of foundation problems.

Our ICC-certified inspectors shoot the floor elevations, map the slab, and hand you the affected footage and the pier count that follows from it. The inspection is free, and so is the written count, the one document that makes every other bid comparable. When piers do go in, they carry a lifetime transferable warranty, and we come back for a performance follow-up inspection each year to confirm the floor is holding where we left it.
