Foundation Cracks, Sticking Doors and Uneven Floors: What They Can Mean

Almost every house has a few cracks and a door or two that sticks. Most are harmless, and a few are early signals of something that needs attention. The trick is telling them apart. This guide covers the common signs, what they can mean and how to keep track of them before deciding what to do.

Reading the Cracks

• Thin, hairline cracks in drywall or paint are often cosmetic, especially in a newer home that is still settling.
• Stair-step cracks that follow the mortar lines in brick can suggest movement, particularly if they are widening.
• Cracks wider than a pencil line, or with one side higher than the other, deserve a closer look.
• Horizontal cracks in a below-grade wall can point to pressure from the soil outside and are worth having checked.

Doors and Windows

A door that sticks only in humid weather is usually just swollen wood. A door that has started to rub, latch poorly or leave a visible gap at the top corner, and does it year-round, can be a sign that the frame has shifted. The same goes for windows that are suddenly hard to open or have gaps around the trim.

Floors That Feel Off

Place a marble or a ball on a hard floor in a few rooms. If it rolls the same direction every time, the floor may slope. Some slope is normal in older houses. A change that appears over months is more important than a slope that has always been there.

Track It Before You Decide

Movement over time tells you more than a single look. A simple routine helps:

• Photograph each crack with a ruler beside it and write the date on the back or in the file name
• Mark the ends of a crack lightly in pencil with the date
• Recheck every few weeks and after heavy rain or a long dry spell
• Note whether the symptoms cluster on one side of the house

Other Explanations

Humidity, temperature changes, a new house settling in and ordinary wear can all cause the same symptoms. That is why a pattern of several signs together, or signs that keep growing, matters more than any one of them.

When to Call

If cracks are widening, doors and windows are misaligned in several rooms or the floors are visibly sloping, it is reasonable to ask a local pro to take a look. Bring your photos and notes, since they make the visit more useful.
