Condensation on windows is a telltale sign of elevated humidity and poor ventilation in the home.   Excess humidity in the air in your home is looking for a cold surface.  Windows, especially metal-framed single-pane windows, are typically the coldest locations in your home – so that is one of the first places water condenses.

What is the cure?

Our home consultants will typically recommend the following upgrades

• Add insulation to walls and ceiling areas.
• Think of insulation as a warm down jacket for your home. 
• If you are seeing mold growth on the exterior walls of your home, especially down lower on the wall or behind furniture, this could be a sign that your indoor humidity is too high and your walls are uninsulated.
• Call us for a free evaluation. 
• We are also licensed insulation contractors and can provide you with insulation recommendations that will make your home warm and cozy, while reducing your energy bills – and reducing the chance for water to condense on your walls.

You can improve the ventilation in your bathrooms by installing a quiet and energy efficient bathroom fan. We also suggest adding a delay timer to the fan, and then running the fan after bathing for at least 30 minutes to remove excess humidity BEFORE it has the chance to increase your homes humidity

Unvented, or poorly vented, combustion appliances are not only a real danger because of toxic carbon monoxide, but these appliances also create water vapor that can add to the humidity load of the home.  We can test these appliances and make recommendations for simple upgrades that will make a real difference for your home.
Install and use a kitchen exhaust fan.  Cooking is one of the major contributors to excess indoor humidity. Removing this excess moisture with a properly sized and installed kitchen fan will reduce indoor humidity levels.
Older homes were built a bit like Swiss cheese. There are lots of holes in homes that are the result of plumbing and electrical openings.  These holes not only make homes drafty and less energy efficient, but they also allow water vapor in moist crawlspaces to migrate into your home.  Crawlspace vapors contain moisture, mold spores, dust, and odors that are best kept in the crawlspace. Our crawlspace remediation teams will recommend sealing gaps and penetrations, and other cost effective measures to improved crawlspace conditions to make your home healthier.
