Choose the repairs you have been told about and see what published references say they cost, added up. It shows ranges built from verified, dated figures, because no honest number can be given without seeing the house.

The interactive calculator needs JavaScript. You can still read how it works below, and the cost guide lists published prices in tables.
How the range is calculated
For each repair, we collected the low and high figures that published references print for it. All figures were checked against the publishers' own pages on October 28, 2026.
The calculator range is the middle (median) of the published low figures to the middle of the published high figures, rounded to the nearest $5. With two references that is the halfway point between them; with one reference it is that reference's own figures, and the repair is marked single reference.
Your total adds up the range for each repair you select, multiplied by the quantity for repairs priced per pier or per crack.
Nothing else is added. The calculator leaves out cosmetic repairs, landscaping restoration, financing costs and anything the references do not price. Its figures are not adjusted for state, ZIP code or inflation.
The references are different kinds: marketplaces that connect homeowners with contractors, repair companies describing their own work, and media or cost sites. The References list below says which is which and gives each one's date. Repairs that rest on a single reference are marked in the calculator.
Common questions
Is this a quote?
No. It adds up price ranges that other publishers have printed. It does not know your house, soil, access, local labor prices or what the work will actually involve. Only a written bid after an inspection is a price.
Why doesn't it ask for my state or ZIP code?
We found no reliable published adjustment by state or ZIP code to apply, so the calculator does not pretend to one. See the cost guide for what drives local price differences.
Why are some ranges so wide?
Because the references describe different jobs and do not say how they were measured. A wide range is an honest answer to a question that cannot be answered from a distance.
How many piers will I need?
HomeGuide says an average house uses 8 to 10; only an engineer's survey of your house can say how many you need.[6]
