Sources Of Humidity In Your Home

In order to control the level of humidity in your house, you need to start by knowing where it comes from. There are several main sources of moisture you can get a hold of right away.

First on the list are rooms or areas where ventilation is poor. From attic to basement, trapped humid air can be very damaging. Also, bathrooms, kitchens and closets may contain damp air, favorable for mildew growth. Be careful with your fireplace, if it’s unused and air doesn’t circulate within. This allows water droplets to infiltrate in the masonry and walls. Mold can grow inside it without you noticing it.

Next, uninsulated surfaces that also make way for condensation. As the warm, humid indoor air reaches a cold surface, moisture turns into water droplets. Responsible for the humid air are factors like cooking or having wet clothes to dry inside. Add washing dishes, bathing or unvented heating appliances. You may start to understand how they are all connected. If your home walls or windows are not insulated, in winter, they are the cold surfaces we were talking about. In summer, condensation finds its way on the cold water pipes, for example. The issue is not a small cold window, it’s more about the large surfaces that communicate with the outside.

Crawl spaces and leaking pipes are one more worrying aspect. If you live in a region with heavy rain, there is a risk that rain seeps into the foundation. If gutters are often stuck or your crawl space is not insulated, look out for imminent damage. Excess water can weaken the resistance structure. Not to mention that it creates conditions for airborne particles to flourish.

Benefits Of Using A Moisture Meter

Before you make the decision of buying a moisture meter, you need some good reasons to convince you. Among the most relevant details that we can provide you with are some of the benefits such a device comes with.

  1. Efficient wood burning

If you have a traditional chimney and your main source of heating is wood burning, you know wet wood is not good. It can lead to heavy soot deposits that turn into fire hazards. Not to mention, the wood’s heat output is drastically reduced when it’s damp.

  1. Safe renovations

When you are building or reconditioning some area of your house, you know time is precious. The level of moisture in the air dictates if you can advance to the next step or not. From concrete to wood, construction materials need specific levels of humidity. For the best results and to avoid wasting time or resources, you can track it.

  1. Better health

Unbalanced levels of humidity can impact your health and lead to unwanted problems. While high humidity may be easier to spot even without a meter, lower levels can be a threat hidden in the dark. You can adjust it using various methods. But a moisture meter is the best tool you can use to know if you are really facing a problem or not.

  1. Budget-friendly investment

Before you jump to conclusions and spend money on (de)humidifiers, you have to be sure. A moisture meter gives you an accurate number as reference. It can save you from throwing money on the window, buying some large device that proves less useful.

Most Important Features Of A Moisture Meter

As many other household items, moisture meters come in a variety of shapes, sizes and models. Getting to know better the main features that you should look for helps you make the right decision. Below, you can find a list of criteria that you can check to ensure you get a moisture meter adequate for your needs.


Considering the purpose you want to use the moisture meter, you may need a model with a wider range. For example, those who work with wood usually have to monitor the extent of the drying process. Dried lumber, compared to freshly cut wood, has a different moisture level. Most woodworking involves a range of 6% to 15%. If you plan to use wood only for burning, accuracy is not something that relevant for you. But for professionals using it to build furniture or wooden floors, precision is key. The more accurate, the better, as the level of moisture influences wood processing. The majority of moisture meters have a working range going up to 50%.


Construction work, renovations versus wood burning involve various levels of access to a surface. Pinless moisture meters allow you to measure up to 3/4 inches deep, while pinned models go up to 3/16 inches.


On average, meters are suitable for measuring wood. Some models work great on concrete and drywall too. Latest models provide a more detailed insight on their display. They can even reflect the average values for a specific type of material.


Investing in a moisture meter should not bring you a headache when you put it to work. Search for a model that is easy to use and has a clear display, that will not give you extra-trouble. Pinless meters, for example, scan wider areas without causing any damage. Pin meters may require several rounds of poking to get a reliable average.


Depending on your budget, you can find moisture meters at a very affordable price (less than 50$). You can also explore the more high-end versions that can reach up to 300$ in price.

Informed buying decisions make space for more questions. And a topic like moisture meters is no exception. We brought together answers for the most common concerns. Check this section to elucidate the mystery around the most frequently asked questions.

What is relative humidity?

Relative humidity reflects the amount of moisture in air, at a specific temperature. The lower this factor is, the less moisture problems exist in your home.

What is the ideal level of moisture in summer?

On average, a 50% level of moisture is usually considered adequate for the summer. As humidity increases in winter due to condensation, the ideal value for the cold season is lower. Around 25% is preferable.

How do moisture meters work?

Pin moisture meters assess the electrical resistance between the two pins (as electrodes). Electricity flows easier where moisture is present within the wood. As expected, while wood becomes dryer, its resistance to the electrical flow increases.

Pinless meters feature an electromagnetic sensor pad. This comes into contact with the wood surface, without needing to cause any damage. These devices can measure moisture content from the surface down to 0.2 inches. For deeper measurements, they can reach up to 1.5 inches.

How do I know if I have too much humidity in my house?

The most common signs that you have too much humidity in your house are rather visible. Condensation on windows during the winter is one of the most frequent. Adding to this, mold can grow on kitchen or bathroom surfaces. Paint can start to peel or crack both on the inside and outside. Any signs of allergies can be on the list too, due to overflowing dust mite infestation.

Can moisture meters detect mold?

Moisture meters can be of great help to detect mold infestation risks. Once mold is visible on walls or cabinets, that may be already too late. Moisture meters can scan and flag areas with excessive humidity within a surface. That is where mold spores flourish, so finding it in time can save you time and resources.

Does static electricity affect meter readings?

Cold and/or dry climates are where static charges can impact the meter readings ranging under 8 %. The analog meter pointer may “jump” all over the scale. If you have a digital display meter, the numbers may flash out of order. You can reduce the effect of static, with some simple measures. First, place the electrode pins into the wood with the device turned off. Turn the meter on after you are ready for the reading. Place your hands on both sides of the pins to help discharge the static. Pass over the board’s surface with a damp cloth before driving the pins.

What are the best ways to reduce moisture on a budget?

Control the common sources of moisture, such as cooking or bathing. Cover the pans often, increase ventilation indoors. Open the windows or keep doors open to improve the airflow, even during the winter. Insulate cold-water pipes where condensation tends to happen. Seal the cracks and put at least a plastic cover in your crawlspace, to stop the cold moist of the soil from coming up. Install some venting fans in the bathroom or kitchen, for better air circulation.

How can I improve humidity levels when it’s too low?

Consider adding a green corner to your space. Plants release oxygen, improving the quality of the air you breathe. But they also emit some moisture, which can contribute to your comfort. If you don’t want to invest in a humidifier, plants can be the most accessible, eco-friendly solution.

How to keep a moisture meter working properly?

Usually designed to last for a few years, moisture meters don’t need much maintenance. Try to store the meter in a clean, dry place and replace the batteries and pins whenever needed. Check the user’s manual for any specific recommendations from the manufacturer.
