How much does foundation repair cost?

More detail

Foundation quotes vary widely and much of the variation is legitimate, so the useful skill is knowing what drives the number. Typical ranges in this market. Push or helical piers at $1,200 to $2,500 each installed, with spacing determined by the design and most settlement jobs needing somewhere between four and a dozen. Carbon fiber straps at $600 to $1,200 per strap, spaced by engineering, so a single wall is often four to eight straps. Steel I-beam reinforcement at a similar or somewhat higher per-unit cost. Wall anchors at $700 to $1,400 each installed including the yard excavation. Crack injection at $400 to $900 per crack. Crawl space support posts and beam work at $1,500 to $6,000 depending on span and access. What legitimately moves a quote. Access, since a pier installed in a tight crawl space costs more than one in an open yard. Depth to competent bearing soil, which is site-specific and not knowable precisely until installation. Whether the scope includes lifting or only stabilizing. Interior versus exterior pier placement, since interior work means breaking and repairing slab. And restoration of drives, patios, and landscaping. What should prompt a question. A per-pier price far below the market range, which usually means shallower piers or wider spacing than the load calls for. A bid with no engineered design behind it on a significant job. A fixed price quoted over the phone without a site visit. And any pressure to sign the same day, which is common enough in this trade to be worth naming. On financing and insurance: this is generally not an insured loss (see the separate question on coverage), so it is an out-of-pocket capital expense, which is exactly why a second opinion on a five-figure recommendation is proportionate rather than paranoid.
