Cracks in Your Walls – Causes and Solutions

Noticing Cracks in Your Drywall?

Cracks typically form on the walls of a house due to settling. The causes of the settlement can vary. Whenever a crack appears on the drywall in a home, it is safe to assume that the walls lack the proper support. The good news is that a trained professional should be able to identify what is causing the cracks with a little investigation, along with the best solution.

If you suspect your home is settling due to cracks in the walls, the next step is to identify what is the cause of these cracks. Depending on the type of foundation your home is supported on, the repair methods vary.

Here are the Top 10 Causes of Cracks in your Walls:

  1. The foundation is settling
  2. The floor supports, aka piers, are settling
  3. The main girder beams are sagging or bowing under the weight of the home
  4. The floor joists are sloping
  5. The beams or joists are crushing under the weight of the home, aka ‘Compression’
  6. The house was designed improperly, without adequate beams under the walls
  7. The partition walls were installed between floor joists
  8. The walls were installed “mid-span” without extra support underneath
  9. The house is shrinking due to a decrease in moisture
  10. The house is swelling due to an increase in moisture

Since there are many causes of wall cracks in a house, it’s important to accurately access the conditions. An abundance of crawl space moisture is usually obvious to the untrained eye but an accurate assessment of the structure is necessary to identify the true source of the cracks.

Depending on the precise supports directly underneath the walls with cracks, you would want to apply the correct solutions. Since there are many causes of drywall cracks, there are many solutions that could be used to prevent the cracks from worsening

Here are Some Great Solutions to Stabilize and Stop Cracks from Getting Worse:

  • For cracks on exterior walls, push piers are the most reliable way to stabilize the foundation
  • For settling piers, new footings and crawl space floor support jacks work great
  • For sagging beams, new footings and floor supports work great OR steel reinforcement
  • For sloping joists, new beams and floor supports or joist sisters are ideal
  • For compressed beams and joists, eliminate moisture and sister the joists
  • For under-supported walls, add more support
  • For walls between joists, add more joists or install “ladder blocking”
  • For walls situated “mid-span”, add new beams and floor supports
  • For shrinking houses, adjust your dehumidifier to a higher humidity setting
  • For swelling houses, control the moisture under your home (various solutions).
