A Damp Basement

Sign 1: A Damp Basement

Most often, it is the basement that suffers from high humidity. Does your basement feel damp or have higher levels of humidity than the rest of your home? In some cases, there may be leaks because the pipes have become old and corroded.

In others cases, it can be because the faucets have been damaged, causing water to drip. If there are no leaks or other evidence of water intrusion, a dehumidifier may be the answer. Such dampness can be the case even if your house has a HVAC; heating ventilation air conditioning system.  

During hot and humid summer months, the air conditioner; HVAC may not recirculate the cool and dry (A.C. treated) air to the basement. Your basement must have a return vent to recirculate air. Even when the HVAC isn’t running during the fall and spring seasons, damp air can build up inside your basement. Unless your basement is well insulated, it’s natural that moisture will enter through the foundation.

There are other reasons for high humidity. One reason is the incorrect installation of glazed windows. A second reason may be insufficient insulation. Etc…

It’s a matter of your basement’s dew point. The dew point is the point at which air can’t hold more water in gas form in a room.  The excess moisture condenses and the basement becomes damp.

Sign 2: Condensation on Walls and Windows

As per the Environmental Protection Agency, the optimal indoor humidity range is 35-50%. A humidity level above 60% is generally considered too high. These conditions are uncomfortable. They’ll either be too cold and clammy, or too hot and sticky. They also allow for mold, which is harmful to your health.

Condensation is an expression of excess moisture. It leaves a layer of dampness on all surfaces, be it near a wall or a window. High humidity throughout your home is another warning sign. We can use smart thermostats to read humidity levels. 

An affordable humidity meter costs between $10 and $50 and can take readings. Continued exposure to high humidity can cause furniture to rot. This causes damage to other building materials like wood, paint, varnishes and metal wiring.

Paint peeling on the walls is noticeable. The presence of moisture can make a good environment for pests. Pest like carpenter ants and termites like moisture. These pests will eat into the wood and can be hard to get rid of. 

A portable dehumidifier placed in the right spot can pull unwanted moisture from the air. Condensation on windows and walls is a clear indicator that your home is humid. This moisture build-up occurs during winter months.

When outside temperatures plummet compared to higher indoor temperatures, moisture builds-up. Cold surfaces, including windows and insulated walls, cause water to condense indoors. If you notice this in your home, you can be sure that you have an indoor humidity problem.

A dehumidifier can remove the extra moisture and prevent the growth of new mold. If you notice mold growing in your home, you or your family members may start having health issues. You should consider getting a dehumidifier for your home.

Poor Ventilation

The environment can play a big role in your home’s indoor humidity. For instance, if you live in a place that is wet all year and your house lets in too much outside air, it will create increased moisture levels indoors.  

Apart from the general climate, drafty windows and doors are also culprits. Homes that have poor ventilation can create problems, but for a different reason. For instance, if your house is well insulated, it will hold onto excess moisture. Other sources of humidity in your home are:

  • Steamy showers in bathrooms without exhaust fans,

  • Poorly ventilated kitchens (with no vented hood system), and

  • Laundry rooms filled with wet clothes
