This is why, when the building has a problem with the foundation and it needs to be repaired, I found it to be so critical to hire the right foundation repair contractor so that the job is done correctly the first time.
When I hire contractors for most jobs, I take bids and consider all aspects of them, heavily weighting the price in that consideration. However, when I consider bids from foundation repair vendors, I often weight qualifications and reputation much more heavily than I do the bid price in making my decision about which contractor to hire.
I just feel that, when you are dealing with something that is as critical to the building is the foundation is - not to mention as difficult to repair as the foundation ends up often being - it is advantageous to hire the best and not just the cheapest.
