The Cost of Home Foundation Repair

The cost of home foundation repair varies of course, depending on what your problem is. If the foundation problem is due to flooding then the first thing you will have do is get a sump pump. Buying a suction or jet pump on average costs $400 and up. Installing a submersible pump costs $800 or more. 

If broken pipes cause the flooding then you are looking at having to replace them. If this is what you are in for then you can expect to pay about $2000 for one floor of the house if the problem is widespread and affects a lot of pipe. This price is for new copper galvanized piping. 

If you need to do anything to the basement floor including adjusting its underpinnings so that it slopes towards a central drain to avoid flooding then you can expect to pay a private contractor anywhere from $150 to $300 per square foot to fix it. To repair a minor crack in a poured concrete foundation caused by flooding costs between $400 and $800. 

If your foundation walls need rebuilding most contractors will charge you between $30 and $40 a foot. On top of it all you will probably have to pay for sealants and rubber wall membranes to keep water out if you live in a flood prone area or an area where there is a lot of erosion and the soil is known to retain water. This can add thousands of dollars to your bill so you need to have a contingency for these little extras in case the contractor springs it on you.
