Don't Let Summer Mold Set Foot In Your House

This week I heard Meteorologist Bob Maxon say that this was the worst year for mold growth in Connecticut in recent memory. It’s easy to see why. Mold cannot live without water and the record rainfall we’ve had over the past few months means that our area is a veritable feast for fungus.

Mold is made up of thousands of microscopic spores that travel through the air until they land on a surface. They love to live in places that hold water, which is why you often see mold growing on trees, roofs, and other places that stay warm and damp. Indoor mold generally develops after being carried in from the outdoors and homes that tend to hold a lot of humidity are more susceptible to an infestation. Why is this a problem? Many people are sensitive to mold and mildew, especially children and the elderly. It can cause illness, asthma, and a host of other respiratory issues. The worst part is that mold grows and spreads incredibly quickly and cannot be contained without removing its food source.   

So how can you get rid of mold in your living space, or prevent it from making a home in yours? Here are my top tips.

1. Run a dehumidifier in your basement constantly. I have an air-tight finished basement and I still run a dehumidifier 24/7. The goal here is to keep your air humidity at or below 50%. When it’s raining, don’t be surprised if you have to dump the water hold twice a day.

2. Always use the extractor fan while showering or cooking. With so much water in the air from the weather, the last thing you want to do is add more inside your home. Be sure that your fans vent outside, not in the attic. Otherwise, you’ll just be redirecting the moisture to another part of the house.

3. Check your drainage. Gutters should be clean and in working order and your landscaping should slope away from the foundation so you don’t have standing water at the base of your home. Make sure your downspouts extend at least four feet out and away from the house.

4. An air conditioner is not a dehumidifier. Sure, it will remove some humidity but an air conditioner’s main function is to cool the air, rather than remove the moisture. If you find yourself running your A/C unit to control your humidity, you’re going to end up with an expensive energy bill and not too much to show for it.

5. Store soft goods in airtight plastic. People often put winter clothing and bedding up in the attic, which can be a breeding ground for mold if the area is not ventilated properly. Keeping the attic vented is key, good air flow can slow or even prevent mold growth.

In short, a house with high humidity is nothing to ignore. If you suspect that your home might be susceptible to mold, it’s worth purchasing an inexpensive humidity gauge called a hygrometer to find out. Remember, a mold problem can be a serious health risk to your family if not dealt with properly.

Replacement Windows for Less Maintenance and Energy Efficiency

If you swore that this past winter would be the last time you’d put up with drafty, old aluminum windows, this week’s column is for you. Around this time of year, I get calls from lots of people looking for advice and information on replacing their windows. Not only do old windows let lots of warm air out and cold air in, but they are also difficult to clean and maintain.

These days, many people are looking to replace their aluminum windows and sliding doors with a more durable option - something made from vinyl, wood or fiberglass that can withstand the test of time. There are lots of options out there and the one you pick will be based on four very important factors: the climate where you live, the amount of moisture and condensation your home is prone to, the kind of aesthetic you want for your home, and the maintenance required to keep them looking great. Keeping these four deciding features in mind, let’s go through the options.

When it comes to temperature, aluminum conducts heat and cold, which is why it’s a popular choice for cookware. Aluminum windows and doors are notorious for transferring the outside temperature in, which makes them very inefficient in both the winter and the summer. Wood fares better in the extreme seasons, but vinyl and fiberglass windows and doors are made for all weather and are built specifically to keep the warm air in and the cold air out. Remember that only 10 percent of the window is the frame, so investing in double pane energy efficient glass is your best option, no matter what frame you go with.

With our humid summers and damp winters, moisture is a major factor in deciding whether to upgrade your old windows and doors. Because aluminum transfers heat, it can attract condensation and moisture, which can lead to leaks, mold buildup, and rot inside your wall. The mold build-up I see around old windows would scare the life out of you, especially when you remember that you’re breathing those spores in every day! If you have signs of mildew or corrosion from your aluminum frames, it’s time to get them replaced.

Then there is the “look and feel” factor. Many people started replacing their aluminum windows and doors with vinyl so they could achieve a more contemporary look with the various finishes and designs that vinyl offers. Of course, aluminum products can be painted or powder coated to match the style of your home, but there will be maintenance to keep them looking great.

That brings us to upkeep. Be aware that any painted product will begin to chip and peel over time. The look of wood is elegant and timeless but it requires regular painting or staining, just like aluminum. Vinyl and fiberglass are very easy to care for and they don’t peel, fade or need to be repainted. These products are not prone to scratches, dings or dents and can give you a longer, hassle-free lifespan if you take care of them properly.

With summer in full swing, now is a good time to think about replacing old windows and doors for products with maximum energy efficiency and minimal maintenance. If your home still has aluminum and you’re experiencing some of the problems I’ve mentioned, it might be time for an update.

Help! I Can’t Keep My House Cool

After this past weekend’s mini heatwave, I had an interesting reader question pop up in my email inbox. She asked:

“Dear Bob, we live in a Cape Cod style home. This past weekend when the temperature reached almost 90 degrees, our second floor became unbearably hot. The second floor gets incredibly cold in the winter too. What can we do to help regulate the temperature so it doesn’t change with the seasons? - Nancy M., Bristol

Nancy, you’re not alone. This is a common problem in Cape Cod style homes that were built in the 1950s and 1960s. Back then, building codes were much more relaxed and energy efficiency was unheard of, so homes were built with very little insulation or ventilation.

What’s happening in your case is that the outside weather is coming in because there isn’t enough insulation to protect your home. To be even more specific, hot air is getting stuck in the attic and seeping down into the second floor because there is no ventilation to let it out. What’s worse is that the moisture in the air is also getting trapped; giving you a potential mold exposure problem that can easily go right from your attic into your lungs.

So what do you do? First, take advantage of a free insulation inspection from a local area remodeler to see how much insulation you actually have. If you haven’t had the house insulated since it was built, I can guarantee you don’t have enough. If you’ve recently bought your home, now is the time to pay close attention. 

Today, we measure insulation by its “R-Value” and the higher the R-Value, the better the insulating properties. In the 1960’s, R-Value wasn’t a popular unit of measurement and instead, most insulation was measured by its thickness in inches. To give you an example, if a typical 1960’s home was insulated at all, it was probably fitted with an R-10 value, which equates to a little over three inches of thickness. The recommended R-Value for Connecticut’s climate according to EnergyStar today is between R-49 and R-60 for an uninsulated attic and between R-38 and R-49 for a home with a few inches of pre-existing insulation. So as you can see, times they are changing.

If your house is the victim of extreme temperature changes, the easiest and best way to regulate it is to build that barrier of protection. A professional can tell you how much insulation you need and can also perform an assessment to see if any mold has formed in the attic and walls. It’s key to remember that adding insulation will change the way your home breathes, so make sure it is fitted with proper ventilation to allow for appropriate airflow. If you just experienced a cold and expensive winter in your home, this is a project to tackle now to stay comfortable all year long.
