The joys of homeownership are as endless as our house “to do” lists. With so many visible distractions, like peeling exterior paint and leaking roofs, most homeowners don’t find or even think about, foundation cracks until long after they’ve first appeared. And once foundation cracks start, they only get worse and, in many cases, need the attention of a professional. This is especially true of cinder block foundation walls. Foundation cracks are cause for alarm because they allow water to leak into your basement. This water pressure pushes in causing the weakened wall to shift, thereby working the cracks open even more. Foundation cracks can also be a sign that parts of your house are sinking unevenly. Both are very serious! The key to keeping foundation cracks under control is to stay one step ahead of them. Below are some helpful tips for finding and identifying three kinds of foundation cracks so you can catch them before it’s too late. Where To Find Foundation Cracks Foundation cracks most often form where pipes enter walls, at windows, near-tie rods, and in long spans of the open foundation wall. Foundation cracks also commonly appear in corners, pour lines, and in-service holes. fouundation-repair-westchester-county-pa-sundahl-waterproofing-1 How To Identify Foundation Cracks There are three kinds of foundation cracks, that indicate varying degrees of significance.
