Foundation crack injection typically runs a few hundred to just over a thousand dollars per crack. A handful of push or helical piers for localized settling often lands in the low-to-mid thousands. A full perimeter pier system on a larger home can reach five figures. Crawl space encapsulation and concrete slab leveling are usually priced by square footage. Every job here starts with a free, written, itemized quote — these are ranges to set expectations, not a substitute for a real inspection.
Why Foundation Repair Cost Varies So Much
Ask five different companies "how much does foundation repair cost" and you'll get five different answers, because the honest answer is: it depends entirely on what's actually wrong. A single sealed crack and a full perimeter pier system on a settling three-bedroom house are both "foundation repair," but they're not close in price. The real cost drivers are how many piers or injection points are needed, how deep piers have to go to reach stable soil, how accessible the work area is, and whether there's water intrusion complicating things.
Foundation Crack Repair
A single epoxy or polyurethane injection repair is the least expensive category here, typically a few hundred dollars up to a little over a thousand per crack depending on length and whether it's actively leaking. See our foundation crack repair page for how the two injection methods differ.
Push Pier & Helical Pier Installation
This is priced per pier, and most localized settling jobs need somewhere between a handful and a dozen or more piers depending on the size of the affected area. A small corner settlement might only need a few piers; a full perimeter system on a larger home addressing more significant movement can run into five figures. Our foundation repair page covers how piers are engineered per job rather than sold as a flat package.
Crawl Space Encapsulation
Encapsulation is typically priced by square footage of crawl space, since the vapor barrier material and labor scale directly with size. Add-ons like a dehumidifier or structural joist repair are priced separately on top of the base encapsulation. See crawl space repair & encapsulation for what's included.
Basement Waterproofing
An interior perimeter drain system with a sump pump is generally priced by linear footage of wall being addressed, which is why a partial-wall fix costs meaningfully less than a full-perimeter system. Our basement waterproofing page has the detail on what a system includes.
Concrete Slab Leveling
Polyurethane foam leveling for a sunken driveway, walkway, or patio slab is typically the fastest and least expensive concrete-related fix on this list, priced by the square footage being lifted. See concrete slab leveling for how it compares to a full replacement pour.
How to Get an Accurate Number for Your House
Every range above is exactly that — a range. The only way to get a real number is a free, on-site inspection where we measure what's actually happening and give you a written, itemized quote before anything is scheduled. If you're comparing quotes from multiple companies, the FTC's guide to hiring a contractor has solid general advice on what to look for beyond just the bottom-line number — licensing, warranty terms, and getting everything in writing matter as much as the price itself.
