How Many Estimates Should You Get for Foundation Repair?

How many estimates should you get for foundation repair? Two or three, from companies that measure. Not one, because a single bid gives you nothing to check it against. And not five, because drive-by quotes multiply noise, not knowledge. Two or three real assessments, each built on a floor elevation survey, give you independent measurements of the same house, pier plans you can lay side by side, and warranty terms you can read against each other. That is everything comparison shopping can teach here. The rest of this article covers the part that matters more than the count: what to compare across those bids, why pier counts differ so wildly on the same slab, and when a second opinion does more for you than a third estimate ever will. The point of multiple estimates is not price shopping. It is evidence shopping.

Why two or three, and not more

The standard consumer advice holds here: the Texas Attorney General's home improvement guidance says to get more than one written estimate, and one is genuinely dangerous in a trade where scopes are elastic. But foundation estimates are not roofing quotes you collect by phone. A real one costs you a scheduled visit, a walk-through, and an hour or two of your attention, and its value depends entirely on whether the company measured. Past the third measured bid, you stop learning. The elevations do not change with the fourth visit; only the sales pitches do. Worse, quote-collecting past that point tends to select for the companies with the slickest close rather than the best evidence. Cap the exercise: two bids if both arrive with maps and the maps agree, three if you want a tiebreaker or the house is complicated. Then compare properly, which is the next section.

Only count estimates that come with measurements

Before comparing bids, disqualify the ones that are not bids at all. An estimate produced without a floor elevation survey is a guess wearing a price, whatever the letterhead. The survey is the instrument of the whole trade: readings across the slab in tenths of an inch, mapped, so the repair plan can point at the problem it claims to fix. The engineering literature backs this as the minimum standard; guidance from the American Society of Civil Engineers (ASCE) frames underpinning decisions as following from an analysis of cause, movement, and structure, never from a walk-around. So the first filter is binary. Did this company measure my floor and show me the numbers, or did it look at my cracks and name a figure? If your three estimates include two guesses, you have one estimate.

What to compare, in order

Lay the bids side by side and work down, leaving price for last. Scope: what does each company say is moving, and do their elevation maps roughly agree? Two honest surveys of the same house should tell the same story. Pier count and placement: not the number, the map. Every pier should sit on a reading that justifies it. Depth spec: what does the bid commit to? “Driven to refusal with the pressure logged on each pier” is a verifiable promise; “to stable soil” with no log is a vibe. Warranty terms: who backs it, what voids it, what it costs to transfer, and whether the company's history suggests it will exist to honor it. Exclusions: the quiet paragraph where low bids get low. Plumbing testing after the lift, permits, landscaping repair, re-lift terms if the house moves again. Only after those five match does the bottom line mean anything, and by then it usually is not close. The ten contractor questions give you the script for filling any gaps, and our cost guide supplies the published Central Texas ranges to benchmark totals against.

Why pier counts differ so wildly

The spread that shocks homeowners is rarely the price per pier; it is eight piers versus twenty on the same house. Some of that is honest. Companies weight interior readings differently, methods reach refusal at different depths, and reasonable inspectors disagree about where slow movement stops mattering. The rest is pay structure. In much of this industry the person scoping your repair earns commission on what you sign, and pier counts stretch easily when nobody demands the map. You can arm yourself with arithmetic: piers along a moving wall run about six feet apart, so affected footage divided by six is a sanity check, and our free calculator runs that math against your own sketch before anyone visits. When a bid lands far above your arithmetic and the map cannot explain why, you are not looking at a difference of engineering opinion. You are looking at the pattern we documented in is foundation repair a rip-off.

When a second opinion beats a third bid

There is a smarter move than adding estimates, and it fits exactly where people usually reach for bid number three. When two bids disagree hard, or one bid feels padded, or the pressure was high and the evidence thin, what you need is not another seller. It is another measurement, taken by someone who has read the first scope and is willing to argue with it in numbers. That is a second opinion, ours is free, and it works because you bring the first bid: we re-measure, lay our elevations against their pier plan, and say plainly which parts the numbers support. Sometimes that means confirming a competitor's scope, and we do, because the map says what it says. Sometimes it means a smaller job, a drainage fix, or no repair at all. Either way you exit the estimate treadmill with a verdict instead of a fourth opinion. Collect your two or three, compare them in the order above, and if the winner is not obvious by then, make the next appointment a measurement, not a pitch.
