Cracks in walls: Repairs and causes

Wall cracking happens for a reason. Sometimes that reason is nothing to worry about. Other times, it points to serious foundation damage.

Here are several interior wall crack types, and what they mean:

  1. Non-structural settlement cracks
    Plaster wall cracks that appear in the upper corners around your crown molding, as long as they are small and don’t grow or change, are usually nothing to worry about. It’s the same with small vertical cracks.All foundations settle to some extent as the weight of your home puts pressure on the soil below. This shift puts some pressure on load-bearing walls, manifesting in minor settlement cracks which appear at weak spots along your walls—such as around windows, doors and upper corners. Usually, these cracks will run diagonally from the corner of a door or window jamb, or appear in a web-like pattern.

    Once the initial settlement is over, those cracks should remain dormant. If, however, you notice them growing in width, then it could be a sign of active structural shift, which can lead to serious foundation problems and structural damage.

  2. Serious structural cracking
    Horizontal cracks mean trouble, especially when coupled with bowing walls. Horizontal cracking can indicate a lateral shift in the wall, due to excess pressure placed on your foundation from the surrounding soil. Or, it can indicate a buildup of hydrostatic pressure. Or active structural shift.The point is, if you notice a horizontal crack it is absolutely time to contact the professionals.

When you’re unsure about the cause of your wall cracking, it’s a good idea to have an expert take a glance. If this sounds like your situation, schedule a free consultation with us today.

I had three companies give quotes on waterproofing my basement. Helitech was by far the best choice. Mark Keleher, the Home Care Specialist, was extremely knowledgeable. He explained everything in great detail including all of our options. I felt I was making a well-informed decision specific to my home not just being “sold” a one size fits all package. The crew did a great job! They were courteous and answered any questions we had during the project. I trusted Helitech with my home and am so happy with the results.
