What sort of contractor should repair a cinderblock foundation wall?
Building trades for a problem like this usually require an estimate or two. Reliable masons will be more than happy to provide you with references that you can call or visit to check. It is in your best interest to get a fully licensed and bonded contractor to do this job. Yes the price will not be cheap, and the lowest estimate is not always the best. Get at least two or more and if they are very much different ask why. The more questions you ask of them the better the result will be. Remember the professionals make the job look easy and the quality will reflect in their work. Ask the one you select if there is previous work you can go see and check references.
