Never Ignore These 15 Signs of Hidden Danger in Your Home

It’s amazing how many little issues can spring up when you own a house. Just when you think you’re caught up on bills, inevitably something breaks or malfunctions and needs a replacement.

Some of these repairs — such as a broken dishwasher — are simply irritating. But there are certain issues in your home that are more than just minor annoyances. Some problems can be dangerous for your whole family and can lead to serious injury or death.

Ahead, discover the warning signs of huge problems in your home that you should never ignore.

Even if you’re great at clearing the removable lint screen in your dryer, there could still be the potential for a dryer fire.

If you notice your clothes are taking longer to dry than usual, it’s time to investigate the dryer vent line, which can get clogged with excess lint over time. The heat from the dryer combined with flammable lint makes this a huge fire hazard. Close to 3,000 house fires per year can be attributed to improperly functioning dryers.

You might think bubbling paint points to moisture damage, but that’s only true some of the time. It could also mean a termite infestation.

Mud tubes, shredded wings that look like little fish scales, blisters in flooring, hollow sounding wood, or visibly damaged wood are all signs that termites have taken up residence. Never ignore these small signs, as termite activity often goes undetected for years and could completely destroy your home.

When you start noticing puddles in rooms with a lot of moisture, such as bathrooms, it’s a clear indicator there’s not enough ventilation. Left unchecked, you could develop a mold problem that will trigger allergies, asthma, or worse.

One of the first signs of structural damage comes in the form of foundation cracks or deterioration. Pooling water can be another indicator, but it’s often hard to see because it could be happening below the surface.

To avoid this, be sure to clean your gutters and change downspouts every season and situate water drainage at least 6 feet away from the house. Regrading the soil may require the help of a professional.
