  • Condensation Problems?

    In today's news we cover the silent intruder known only as "Condensation."

    Condensation, as we know it, is the change of the physical state of matter from the gas phase into a liquid phase. It can also be defined as the change in the state of water vapor to liquid water when in contact with any surface.

    What exactly causes Condensation?

    You might already be aware that water can form anywhere cold air meets hot air and you've probably seen this first hand on your window at home. This simply means that the cooler the room is, the less it's able to absorb water vapor, so heating the room decreases the potential for condensation. Even insulated walls or windows can experience condensation as a result of what is called a "cold bridge."  This is when a solid element from the cold air outside attempts to  transfer the cold into the warm air inside.

    You'll notice this effect most commonly on glass however, if you check around your home in the cold months for any cool flat surfaces like window sills you'll no doubt see a tad bit of condensation that's formed. The worst part about this seemingly harmless little process is that it accumulates into drops, which run down into the wooden components of the window, causing mould and rot. The solution for this problem can be reduced by adding storm windows or sheet plastic barriers to the outside of the window.

    Condensation in building construction

    Condensation in building construction can cause a real issue as it may cause dampness, mould health issues, wood rot, corrosion and energy loss in your home. In order to alleviate these issues you'll need to consider ventilating your space. This can be done in a number of ways, most of which are simple quick fixes fortunately. Let's take a look at the easy ones:

    • Opening windows,
    • Turning on extractor fans,
    • Drying clothes outside and
    • Covering pots and pans whilst cooking.

    If you have a larger condensation problem you may have to take it a step further. Consider using air ventilation systems as they will help circulate the air in your living space.

    Usually homes lacking damp proofing or insulated glazing are the most susceptible to this sneaky vapor.

    3 Ways to Control Condensation

    Proper Heating

    Dry heat reduces humidity which decreases the potential for condensation.

    Adequately Ventilating Your Home

    Unlike older houses, today's super-sealed and insulated homes are often airtight. This can create condensation problems by reducing air exchange. You've probably noticed that a lot of moisture is generated during hot showers and baths—and it goes straight into the air to await an opportunity to condense on an obliging surface. Installing or updating bathroom exhaust fans are relatively simple and constitute the front line in the battle against bathroom-related moisture problems. Another good one that can make your life easier is adding vents to your clothing dryers that lead outside.


    If high humidity is a problem that can't be overcome by heating or ventilation, use a dehumidifier to reduce the potential for condensation by directly removing the moisture from the air.

    Hints and Tips

    Proper Insulation

    Insulation that blocks and prevents ventilation in an attic can also result in condensation, creating a condition that fosters mold in the framing elements of the house. This can affect your home's structural integrity.

    Pipe Problems

    Pipes that don't have insulation pose potential problems. Warm air contacting cold pipes causes condensation to accumulate on the pipe. As it accumulates, it runs and drips, creating a moisture problem.


    A sealed fireplace can create condensation problems. If air can't circulate in the fireplace, condensation can accumulate on the walls and be absorbed into the masonry.
