Things to consider in foundation repair
The foundation repair industry is responsible for providing competent, accountable installation of engineered solutions for the damage, and/or failure, of load bearing components of buildings and homes. These problems are generally caused by poor or changing soil conditions. Structures are built on foundation footings which are typically concrete pads designed to accept the weight of the structure and transfer that weight onto the soil beneath. If the soil is not compact enough, is filled with tree removal stumps and other unstable debris, or if it changes in density due to dry/wet conditions, then it will not accept the weight of the structure in a consistent manner.
The results can be brick veneer cracks, windows and doors not operating cleanly, chimneys leaning away from homes, cosmetic cracks on interior walls, interior doors not operating properly, water penetration through foundation walls, damaged and/or failing foundation walls as well as potential structural damage all the way up to the roof of the structure.
It is extremely important that competent, qualified contractors, using industry certified products, repair such damage. There is no controlling authority for this type of work other than by the NC state engineering board which mandates that all foundation repair work must be designed and certified by licensed professional engineers. The only oversight of the actual repair work is through the building and inspections permit process administered through the NC state insurance division. Most building inspectors have a very limited understanding of these types of repairs; however, as long as a professional engineer has approved of the design solution, the building inspectors will generally approve also.
So, consumers need to understand that choosing a company to repair damaged foundations needs to include serious consideration for an experienced contractor (preferably a licensed contractor), industry approved products, a certified, engineering design stamped with the engineers seal of approval and a building permit issued by the local building and inspections department.
