The Top 10 Ways to Reduce Humidity in Your Home

It’s never a good sign when humidity starts taking over your home. From condensation on the windows, to mouldy spots, musty odors and water stains, humidity can wreak havoc if you’re not careful. The best way to ensure humidity doesn’t damage your home is having a strong foundation, but there are also some easy changes you can make to banish humidity inside.

Here are the top 10 ways to reduce humidity in your home.

1. Resistant Siding

Investing in siding that’s resistant to water damage and humidity is one of the best steps you can take to protect your home. Quality vinyl siding like Gentek’s selection should hold up no matter the climate, and Sagiper siding is known to excel in high humidity areas. Make sure your home is equipped with the best products to save you hassle in the long run.

2. Storm Windows

Although storm windows themselves can sometimes have condensation, they reduce condensation on the interior windows. By adding a storm window, you protect your home by adding another layer of glass and increasing thermal insulation. Check out more benefits of storm windows on Gentek’s site here.

3. Ventilate

Make sure you have exhaust fans in the kitchen, bathroom and laundry rooms and check that they vent to the outside. If you don’t have exhaust fans, open a window to dry out the air. Ceiling fans and box fans also help to increase ventilation.

4. Invest in a Dehumidifier

If you want to rid your home of humidity, a dehumidifier will reduce humidity levels and odours, reduce irritation to your skin and respiratory system, and lower energy costs by helping your air conditioner run more efficiently.

5. Place House Plants Outside or in One Room

Plants release moisture into the air, so if you’re a plant fanatic this could be the reason for the humidity in your home. Concentrate your plants in one room, or keep them outside for a while until the humidity goes away.

6. Take Colder, Shorter Showers

When you take long, hot showers you increase the moisture in the air. Switch to cold, shorter showers to reduce humidity.

7. Be Mindful of Your Home’s Temperature

The relative humidity in your home will decrease if you raise the indoor temperature, so it’s beneficial to set your heat a few notches higher. Also note that if the temperature difference is too big between indoor and outdoor, humidity will increase inside.

8. Check Your Gutters

Don’t forget to check your gutters. Ensure your gutters are clean so water can leave your home efficiently.

9. Use a Slow Cooker

While stove-top cooking produces a lot of moisture, slow cookers result in less humidity in the air. If it’s not possible to use a slow cooker, make sure to turn on exhaust fans, but think about investing in a slow cooker as soon as you can.

10. Run Washers When Full

If your dish washer or clothing washer isn’t full, refrain from running a load. This will help decrease unnecessary humidity and will also reduce water waste.

If your home is showing signs of humidity, use these tips to clear the air.

Worried about window condensation?


All air contains humidity, and in your home, especially in winter months, you tend to notice that there is more humidity on the inside of your windows.

It’s often referred to as sweating.

Indoor humidity can result from everyday activities such as showers, cooking, your furnace and even mopping your floors… it’s very common. When water vapour comes in contact with a cold surface like a mirror or window, the vapour turns into water droplets called condensation.

So why do your new energy-efficient windows show more condensation than the old ones? It’s simple. Your old windows were not air-tight and allowed heat and humidity to escape, but your new windows come with a tighter seal and the extra moisture in your home is now not able to escape.

But don’t worry. After a few weeks of heating, your home should dry out – reducing if not eliminating condensation.

The table below shows the recommended or comfortable levels of indoor humidity during the winter months.


-20˚F                                                   15% – 20%

-10˚F                                                   15% – 20%

0˚F                                                    20% – 25%

10˚F                                                    25% – 30%

20˚F                                                    30% – 35%

(Indoor humidity can be measured with a humidistat or psychrometer.)

Here are a few ways you can help reduce humidity in your home:

  • Use kitchen, bathroom and laundry room exhaust fans after humidity-producing activities
  • Air out your home periodically, it helps get rid of stale, moist air
  • Adjust your humidifier to the recommended setting for your home
  • Make sure air circulation is adequate in your basement and attic
  • If troublesome condensation continues, see your heating contractor
