Without a solid foundation to stand on, the average American home would collapse — literally. That’s why, as a homeowner, it’s your responsibility to make sure your home’s foundation stays in good repair and is free of the basement cracks and leaks that can help foster water damage.

However, it can be tough to know how to detect signs of water damage — especially if you are a first-time homeowner.

If you’re not sure how to tell if your home is at risk for foundation damage and needs a basement waterproofing, check out these four common symptoms and indicators of water damage in a home’s foundation:

Basement cracks and leaks

If you notice visible cracks in the inner or outer walls of your basement — or that your basement leaks when it rains — then water damage has either already occurred or will do so soon. In this case, it’s best to seek out a foundation repair company for repairing foundation cracks before the problem worsens and becomes more expensive to fix — especially when significant water damage can cost an average of $3,000 to $5,000 to repair.

Drafty or musty air in the basement

Noticeably moist or drafty air in the basement is another sign that water damage is taking place. And when mold, a major health hazard, can begin growing in just 24 to 48 hours after entering a basement, it’s essential to make sure any moisture is prevented from entering your basement by investing in a repair procedure.

Doors and windows failing to latch or close

If your home’s windows and doors aren’t latching or closing properly, this may mean your home’s structure is warping due to a damaged foundation or moisture intrusion. Either way, it’s essential to get the problem fixed as soon as possible.

Creaky, noisy or “bouncy” floors in the upper part of the house

Noticing that your floors tend to creak or bounce when you walk around the house? This isn’t just an annoyance — it’s an indicator that your home’s frame is warped due to a damaged foundation. Your home may need extra structural support, in this case.

With the right foundation repair, you can instantly fix any basement cracks and leaks or other problems and increase the value of your home at the same time.
