Is Your Basement Floor Sinking?

October 16, 2018 1 Comment

Building a home takes skill. Your house was probably built by someone who created many of the homes in your neighborhood. Most every home has a basement. Many have finished basements. Some have finished areas, and room for storage and some homes have unfinished basements. Finished or unfinished, your basement floor is made of concrete and may be sinking as you read this!

How do you know if your basement floor is sinking?

Know the warning signs that indicate the basement floor needs repairing. Humidity levels rise in the summer and with that, wood swells making windows and doors hard to open. Not being able to open the doors in your basement is one indication that there may be a void under your floor. Take a look at areas where the walls meet your ceiling. Do you notice any gaps along that line? Evaluate the places where your baseboards meet the walls. Look for the same thing. Look for a gap between the baseboard and the wall. They will seem to separate. If you have visible support beams in your basement, you may notice the beam starting to pull away from the ceiling. When this happens, it also compromises the upper floor, which uses these beams to support their flooring. Another warning sign is the floor feels like it is sloping from one side to another. It may also be sloping to the middle of the room. If you pull up your carpeting and see cracks in the cement, that is a sure sign that your home’s concrete basement floor is sinking.

Why did the basement floor sink?

Concrete slabs sink because the earth beneath it begins to compress due to evaporating moisture in the ground. Lack of rainfall or snow can affect not only your basement but your garage floor, driveway, sidewalk, patios and steps. Your contractor is usually not to blame for your concrete slabs sinking into the ground.
