Moisture and Its Negative Effects on Your House

Home insulationHome insulation is often absent or lacking in older houses. From rotting siding to broken seals around windows, from a sticking patio door to bad attic ventilation, insulation is often the one that takes a hit when a house ages.


Lack of ventilation and lack of insulation both have one thing in common: the presence of moisture. Condensation is one of the culprits behind such problems. And you know what happens when there’s moisture: it’s never a good sign.

Condensation forms when warm air hits a cold surface. The cooler air surrounding the cold surface — say, window glass — cannot hold as much moisture as warm air does. So condensation forms. The resulting water vapor first appears on the cold surface, then when there’s enough moisture, it drips to the floor, on furniture, on the carpet, etc.

Water Damage

What all this leads to is water damage. Your appliances are affected, so is your furniture, your walls, floor, attic, and eventually the foundation. Enough condensation or leaks will bring rot from top to bottom of your house. When water enters walls, it may compromise the safety of your electrical wiring. For older houses or whatever house that you didn’t build from the ground up, TASCO, Inc. says an electrical wiring tracer is your only hope of finding areas within your walls that you’re supposed to check for moisture first.

Insulation & Ventilation

The best way to deal with this problem is to call your contractor and ask for assistance. If there’s rot or worse, repairs and replacements become inevitable as cleaning and drying cannot solve the problem permanently. Your contractor will likely check your attic and look at the vents. Your walls should be free from cracks and holes, as well. Your roof, doors, windows, and siding all play a role in making your insulation system work. The presence of moisture may encourage the growth of mold and mildew, which may cause additional problems with your health.

Don’t neglect the lack of proper ventilation and insulation. Bigger problems will happen eventually if your house has too much moisture.
