Rain, Rain Go Away - Protect Your Home From Moisture

Chelsea O'Donnell

With all the rain we’ve been getting plus warming temperatures, humidity in the house is going to be a major problem for many homeowners this coming season. While we all love summer, not dealing with moisture early can make your home and uncomfortable and unhealthy place to live.

Most people combat humidity by using air conditioners, and while they can reduce the moisture in the air to some degree, this is by no means their primary function. An air conditioner works by sucking the air from your home, cooling it, and blowing it back into the house. That process does reduce the humidity slightly, but pairing your air conditioner with a dehumidifier is the best way to cool down your home so you can sleep more comfortably at night.

 A dehumidifier works by pulling the moisture out of the air and storing the excess water in a holding tank. Many people keep dehumidifiers in their basement all year long to control the dampness that can often be felt in these underground areas. This is a great idea because controlling the humidity in the dampest part of your home will very likely help to regulate the rest of the house.  One way to know if your house is holding a lot of moisture is to purchase a simple five-dollar humidity gauge, called a hygrometer, from the local hardware store. Ideally, you want the humidity level to be under 50%. If it’s higher, you might want to consider using a dehumidifier in the main part of your home, especially on hot summer days and in areas where you spend the most time.  

In addition to cooling the air and decreasing moisture, running a dehumidifier during the hottest parts of the hottest days can also prevent mold and mildew growth, eliminate musty odors in the home, and prevent old pipes from sweating. Plus, you can use the water collected in the tank to give your outdoor plants a good drink! Dehumidifiers generally run on about half the energy of an air conditioning unit, so as long as you don’t run them all day, using one shouldn’t affect your energy bill. Just be sure to keep windows and doors closed when you run your unit, and only switch the power on during the most humid time of the day, or when the air is above 50 percent humidity.

Be aware that dehumidifiers by nature are drying, so try not to run them while you’re occupying the room over a long period of time, like when you’re sleeping at night. Also, be careful about using dehumidifiers in conjunction with an attic fan. I see people do this all the time and they unintentionally throw the excess moisture from their home or basement up into their attic, where it has no place to escape. 

If you’re thinking that a dehumidifier might be a good solution for you, they come in different sizes and can be used for residential or commercial purposes. Generally, a unit will come in 25, 30 and 40-pint models, and on average a 25-pint unit will be sufficient to operate in a 1,000 square foot area.

Finally, if you have a dehumidifier, please be sure to keep the filter clean. Dust, dirt, and debris can get caught in the filter, preventing air from flowing freely and potentially circulating mold spores throughout the home. A simple wipe down with a damp cloth and spray bottle will do the trick to keep you breathing freely and ensure a longer life for your appliance.

April Showers Bring Roof Mold

Chelsea O'Donnell

Warmer temperatures and rain can only mean one thing this time of year. It’s roof mold season. My phone rings off the hook for cleanings in April and May when moisture and humidity kick into high gear, giving mold and mildew the perfect opportunity to thrive. So what’s with the black, streaky stains popping up on everyone’s houses and what can you do to get rid of them?

Stains on the roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until they have enough moisture, heat, and humidity to grow and spread. Now don’t be too alarmed, algae isn’t necessarily going to ruin your roof immediately, but it does affect the curb appeal of your home and the problem could end up damaging and pulling up your shingles if not dealt with for a long period of time.
An interesting fact is that copper, zinc, and lead are toxic to algae, and many newer roof shingles contain copper granules, which act as a barrier against any mold growth. Homes with older roofs won’t benefit from this technology, but it explains why you won’t see algae where metal flashing has been installed. If you’re susceptible to algae and in the market for a new roof, be sure to inquire about this type of shingle.

So now that we know what it is, how do we get rid of it? The easiest way to rid your roof of algae is a good cleaning solution, which can be picked up at the hardware store, applied using a pump sprayer and rinsed with the garden hose. One tip is to give any plants below the roof a good drink of water beforehand so they don’t absorb the solution. If you’re not comfortable on a ladder, call a professional to help you complete this task. A clean roof isn’t worth a trip to the hospital, and a local area home improvement specialist will be able to complete the job in just a few hours.

Once the roof has been cleaned, you might want to do something to prevent the mold from coming back again. As I mentioned, copper, zinc and lead-coated sheet metal are toxic to algae, so installing a strip of flashing will help stop that nasty fungus in its tracks. Choose a strip that’s at least six inches wide, and have it installed at the roof peak to ensure that the metal molecules wash down with the rain and protect the roof from mold build up.

Winter Basement Leaks - A Common Problem To Look Out For

Chelsea O'Donnell

I often talk about the importance of proper attic ventilation to prevent leaks but as the winter peaks, the basement takes center stage as the place in the house where water damage will most likely occur.

The temperature often rises after a big storm, making moisture a huge problem for homeowners. Standing water can find its way into your basement through non-structural cracks in poured concrete walls or deteriorated joints in masonry walls. Poorly fitted or old basement windows, as well as utility openings, can also let water in.

The best line of defense against a wet basement is to make sure that the water is directed away from the foundation. Inspect your gutters and downspouts to see if they are working the way they should be and also check to see that the ground right around the house is higher than the rest of the yard. Having the yard grade at its highest around the perimeter of the foundation will ensure water drains away from the house instead of into it.  

If you think your house is susceptible to leaks, you can also use a waterproofing membrane or coating to seal the foundation or basement area. However, if you have regular leaking problems, you may need to have a drainage or sump pump system installed by a professional.

Even if you don’t have a leak problem, the basement can get pretty damp from now through April, which creates the perfect environment for nasty mold and mildew to grow and fester. To get rid of the excess water, I always like to run a dehumidifier in the basement as the weather warms up. A dehumidifier works by pulling the moisture out of the air and storing the excess water in a holding tank. Many people keep dehumidifiers in their basement all year long to control the dampness that can often be felt in underground areas, but I find it especially useful this time of year.

You can find out if your basement is holding a lot of moisture by purchasing a simple five-dollar humidity gauge from the local hardware store. Ideally, you want the humidity to be under 50%. If it’s higher, a dehumidifier might be a good solution. Generally, a unit will come in 25, 30 and 40-pint models, and on average a 25-pint unit will be sufficient to control the moisture in a 1,000 square foot area.

One last word of advice - if you have a dehumidifier or plan on getting one, please be sure to empty it regularly and keep the filter clean. A simple wipe down with a damp cloth and spray bottle will do the trick to keep you breathing freely and ensure a longer life for the appliance.
