How to Lower Humidity in Your Home: A Damp Expert’s Opinion
A certain level of moisture in the air is essential for comfort and health, but when it rises too high, it can lead to many issues.
High humidity levels can cause discomfort, musty smells, or more serious concerns like mould growth, structural damage, and health risks. This can impact both your home and your quality of life.
Understanding how to control and lower humidity levels in your home will ensure you are more comfortable and prevent long-term damage to your property.
There are several strategies, from simple fixes to more advanced solutions, that you can use to reduce indoor humidity and create a healthier, more pleasant living environment. Explore more about them in this blog.
Why is high humidity a problem?
High humidity can create a lot of problems in your home. When the moisture level in the air rises above a certain point, it creates the perfect conditions for mould, mildew, and dust mites to thrive.
These can trigger allergies and respiratory issues such as asthma, particularly in children and elderly individuals. If you suspect your property might be having these, contact a specialist or book a free survey.
Excessive humidity also puts your home’s structure at risk. Walls, ceilings, and wooden fixtures can become damaged as the moisture causes warping, peeling paint, and weakening materials. If left unchecked, you may find yourself dealing with more costly repairs down the line.
The higher moisture content also makes the air feel warmer than it really is, leading to higher energy bills as you try to compensate with fans or air conditioning.
The ideal level of humidity
So, what’s the right amount of humidity for your home?
According to the Environmental Protection Agency (EPA), the ideal indoor humidity level should be between 30% and 50%. Anything above 60% is considered high and can lead to the issues we mentioned earlier.
Maintaining this ideal humidity range can improve your comfort, prevent potential health risks, and help protect your home from moisture-related damage.
Ways to lower humidity in your home
There are several steps you can take to manage and lower humidity levels in your home.
Some are simple adjustments, while others may require small investments or repairs. Below are some ways you can reduce humidity in your home:
Buy a dehumidifier
One of the most straightforward ways to lower humidity in your home is by using a dehumidifier. They reduce the overall humidity level by pulling the moisture from the air.
There are dehumidifiers of various sizes and capacities, making it easy to find one suitable for your space. For high-humidity areas like basements or bathrooms, a larger unit may be needed, but smaller rooms can benefit from portable dehumidifiers.
Running a dehumidifier regularly can help maintain a comfortable humidity level and prevent the build-up of moisture that can lead to mould growth and damp problems.
Improve natural ventilation
Natural ventilation is another effective method for reducing humidity. By increasing airflow throughout your home, you can help disperse moisture-laden air and replace it with drier, fresh air from outside. Opening windows and doors, especially during cooler parts of the day, allows trapped humidity to escape and improves air circulation.
For best results, consider cross-ventilation—opening windows on opposite sides of a room to create a breeze that pushes humid air out and pulls fresh air in.
Install extractor fans
Bathrooms and kitchens are common sources of humidity due to showering, cooking, and boiling water. Installing extractor fans in these rooms can help by drawing moisture out of the air and releasing it outside.
Ensure that the fans are vented correctly, as fans that simply recirculate air back into the room won’t reduce humidity effectively. Running your fans after showers and while cooking can make a big difference in controlling moisture levels.
Keep your home warm
It might seem counterintuitive, but keeping your home warm can help combat humidity. Warm air holds more moisture than cold air, so when your home cools down, that moisture can condense on surfaces, causing dampness.
By maintaining a stable, comfortable temperature, you can prevent this condensation from occurring. Central heating systems, radiators, or space heaters can help maintain a warm environment, especially during the colder months when humidity levels tend to rise indoors.
Reduce moisture production
Another way to lower humidity is to reduce the amount of moisture being produced in the first place. Simple habits such as covering pots while cooking, avoiding overwatering plants, and hanging wet laundry outdoors can help cut down on the amount of moisture released into the air. Have a look at our dedicated blog post on condensation in bathrooms.
Using lids on pots and pans during cooking, for example, can significantly reduce steam, while ensuring clothes dry outside or in a well-ventilated space prevents extra moisture from being added indoors.
Insulate your property
roper insulation can also help manage humidity levels. Insulation helps maintain a stable temperature inside your home and can reduce condensation, particularly in areas prone to dampness like basements or attics.
Double-glazing windows, insulating walls, and ensuring your roof is properly sealed can prevent cold surfaces from meeting warm, humid air, which leads to condensation. Insulating your home not only helps reduce humidity but also increases energy efficiency.
Tackle leaks or damp
Leaky pipes, cracks in walls, or poorly sealed windows can bring unwanted moisture into your home. If you notice damp patches on walls or ceilings, it’s important to address the source of the leak immediately. Ignoring leaks can result in prolonged exposure to moisture, leading to structural damage and an increase in indoor humidity.
Leaky roofs and damage to exterior walls can develop into penetrating damp problems.
Regularly check for any signs of leaks, especially in areas like basements, bathrooms, and kitchens, and have them repaired as soon as possible.
Moisture absorbing items
Another low-cost way to reduce humidity is by using moisture-absorbing products. Items such as silica gel packets, charcoal, or specialised moisture absorbers can be placed in areas with high humidity, such as closets, bathrooms, or basements.
These products work by drawing moisture from the air and trapping it, helping to keep humidity levels in check without the need for electricity or large devices. Just remember to replace them regularly for continued effectiveness.
How a professional can help
While many of the steps listed above can be done by homeowners, there are times when professional assistance may be needed. Particularly if you’re dealing with severe humidity problems.
Professionals, like ourselves, can conduct a thorough inspection of your home to identify the root causes of excess humidity, whether it’s poor ventilation, leaks, or insufficient insulation.
