Although pier and beam foundations have dropped in popularity over the years there are still many crawl space foundations in north Texas. There remains crawl space home that date back a hundred years or more. There is also a trend toward modern homes that have been built over the last twenty to thirty years. 

The problem is that  crawl space construction has evolved over the years and "one repair procedure fits all" does not work anymore, in fact it never did.  There have been changes in design and with  the materials that have been used. This includes: from the type of piers used to  support the floor to the type of materials used for the perimeter support.

The one constants seem to be the fact that the soils support the perimeter and the underfloor piers, and if the soils shift the foundation shifts, then cracks appear and the floor tends to become uneven. Add to that moisture problems in the crawl space, around the perimeter, with the air vents and under floor wood deterioration. These are a few of the problems that must be dealt with when foundation problems become evident..

While many may claim to know how to deal with pier and beam movement  fewer and fewer companies or individuals really understand, how to work on, or want to work on crawl space construction. Those that do work on them often don't address the actual problem... most anyone can stick a jack under a floor, jack it up and slip some support between the ground and the wood under the floor and this can show a temporary improvement. But it takes years of experience to understand the cause and effects of the many different types of crawl space construction and the many aspects of getting it right.. They must understand the soils, the moisture, the type of floor supports, the type of perimeter supports, the amount of venting required, the best way to access. There is a lot to properly repairing a failed pier and beam foundation. And many just don't get it right!
