In the Northeast, we all know that with hot summer temperatures comes high humidity, but too much humidity in your home can cause mold growth, along with being just plain uncomfortable. The ideal relative humidity level is 30-60%. If you notice condensation on interior glass, mold spots, a musty smell, damp walls, or water stains, your humidity level is too high. Here are some things you can do to fix your problem!

1) Turn off your humidifier or vaporizer and use a dehumidifier

When you notice the signs of excess humidity, turn off your humidifier—and don’t turn it back on until your humidity level is under control.

A dehumidifier can help you the most. Place your dehumidifier in a basement or in a bathroom with closed windows and doors, and place them away from walls and furniture to ensure proper ventilation. We can also install a whole-home dehumidifier that works with your central air system.

2) Place house plants outside

House plants release moisture, and the moisture from the soil can evaporate and add to your humidity problem. If you have a lot of houseplants, consider keeping them outside until your humidity is under control.

3) Store fresh-cut firewood outside and away from the house

Freshly cut firewood still contains moisture that needs to evaporate. Until your firewood is completely dry, storing it away from your house can prevent the moisture from the evaporation of the water in the firewood from further contributing to excess humidity issues in your home.

4) Check your moisture barrier

When your moisture barrier is compromised, your humidity increases and can cause problems. If you have a crawl space, make sure the dirt floor is completely dry and covered in a polyethylene ground cover. If your soil isn’t completely dry, you can use fans to dry it out before putting on that ground cover.

5) Install ventilation fans

In kitchens and bathrooms, ventilation fans can solve your humidity problems. Cooking foods—especially on your stovetop—creates more condensation. You can either cover your food while cooking it, or make sure to use your exhaust fan!

6) Seal air leaks

Another cause of excess humidity might be an air leak. To test for one on your own, take a lit incense stick or smoke pen and hold it in front of where you think the air leak might be. Places that commonly have air leaks are windows, doors, electrical outlets, and attic hatches. You’ll know you’ve found the air leak when the smoke travels horizontally. To remediate this, you can seal the leak with caulk on your own.
