As a Tucson Home Inspection company, we recommend you seal up any and all cracks in your Tucson Home as a precautionary measure against water seepage and insect penetration.
Cracks in poured concrete or concrete block, Stone, or Brick foundation walls can result from shrinkage, differential settlement, lateral pressure on the wall by the soil, or poor workmanship. It is not uncommon to find short cracks in the foundation and walls of your Tucson home. Crack can be a result from movement over a period of time and can result in destabilizing the structure.
Cement block, brick, and stone foundations have a greater chance of water seepage than poured concrete foundations due to the numerous joints. Since it is not possible to determine from a single visual inspection whether the cracks differential settlement is active or dormant, the wall should be checked for incremental movement over a period of time, usually over several months or years.
It is certainly possible for you to look around your Tucson property yourself for any cracks in the walls and foundations and to seal them upon locating them. However, having a licensed and experienced home inspector perform a thorough inspection is your best course of action.
