Keep Humidity Away From Your Home This Summer

With a very hot start to the week followed by cooler temperatures, it probably won’t be long before summer weather is in full swing.

With New England's heat comes humidity, which is something every homeowner needs to keep in check. While we can’t control the weather outside, moisture in the house can be a major problem, contributing to mold, mildew, and overall dampness, especially in the attic and basement.

A lot of homeowners combat humidity by using air conditioners in their houses, 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 basements 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 part of your home that holds the most water 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 from the local hardware store. Ideally, you want the humidity to be under 50 percent. 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 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 filled with a cleaning solution will do the trick to keep you breathing freely and ensure a longer life for your appliance.

What’s Growing In Your Attic

This past week’s brutal temperatures had plenty of people thinking about the heat in their homes. While high energy bills, drafty windows, and cold floors are the obvious issues, what most homeowners don’t see is what’s causing the biggest problems in their homes. 

Most of the houses in our area are underinsulated and not properly ventilated. We all know from high school science class that heat rises, right? In a house, that means a good amount of heat makes its way up to the attic where it’s usually pretty cold. When warm and cold air collide, it creates moisture or condensation, which is the last thing you want up there. As an attic collects moisture, it adheres itself to any surface, which in an attic’s case is usually wood. That moisture becomes an ideal home for mold spores, which eat away at the plywood, causing it to rot. 

An attic that has enough insulation and ventilation allows air to flow through and temperature to regulate, which creates a healthy atmosphere and keeps a home warmer in the winter and cooler in the summer. A home without proper insulation and ventilation is susceptible to mold infiltration which will create rot, roof leaks, and can even become a potential health hazard in your home, especially for folks with asthma or allergies. 

So how do you know if your home has enough insulation and ventilation? A roofing contractor will be able to help you identify exactly what you need, but a good place to start is insulation. Insulation is measured by its R-Value, which is the level at which heat can penetrate it. According to EnergizeCT, the recommended R-Value for a home here in Connecticut is R38 to R60, which is roughly 12 inches thick at the low end of that range. If you can access your attic, you’ll be able to get an idea of your insulation situation. More than 75% of homes I visit don’t come close to an R-Value of 38, in fact, homes built before 1940 didn’t require insulation at all. Those built in the decades after usually have enough to be suitable for winter in Florida. 

A warm, energy-efficient, and healthy home always starts at the roof. Ensuring your home has enough insulation and ventilation is the best way to prevent bigger problems such as leaks from happening in the future. Plus, getting your home insulated and ventilated properly offers both tax credits and will immediately make a big difference in those energy bills. Don’t forget your family’s health as well. Illness from long-term exposure to mold is not something anyone wants to deal with.

Keep an Eye on Winter Energy Bills

Holiday lights, Christmas trees, and colder temperatures mean that December is usually one of the most expensive months in terms of utility bills. Add all of this to power company rates on the rise and you can see why it’s a great time to take a closer look at your energy usage. 

One resource that not enough people take advantage of is an audit by Energize Connecticut. For a fee, a home energy consultant will come to your home and conduct a full assessment, covering your furnace and water heater, air ducts, windows, doors, and more. Plus they can offer rebates for upgrades and repairs. To apply, visit the EnergizeCT website and choose your service provider. 

If you’re not interested in an assessment but would still like to enjoy some serious home energy savings, here are the top five spots I always check for air leaks and heat loss. 

1. Windows. Believe it or not, hanging heavy fabric drapes can help you retain up to 25% of the heat in your home. This is especially true with large glass doors that aren’t being used in the winter months. Also, be sure to check for gaps. Wooden window frames get warped with age and can lead to serious air leakage. For cracks that are smaller than a quarter of an inch, a silicone caulk will work to plug up areas where heat is escaping. Also, if you feel air coming right through your single panes and the glass rattles with the wind, beef them up with some shrink film. This product can be found at any home supply store and can be cut to size. 

2. Doors. We don’t often open the windows in the winter, but doors are a different story. They let lots of air escape, but they can’t be sealed completely because we need to use them. I always suggest inspecting your door sweep to ensure it’s not damaged and replacing it if the bristles have come loose. A door snake or seal can also come in handy, which can be purchased at any big box store or even made at home with an old pair of stockings and some rice, beans, newspaper or another filling.

3. Attic. Those of you with an attic hatch are likely losing a ton of warm air through its frame. We all know that hot air rises, so seal up that hatch with heavy duty plastic, or build yourself an insulated box to fit over the entryway if you still need access to storage. 

4. Water Heater. Insulate your water heater’s tank and pipes with fiberglass. For the tank, fit a fiberglass blanket using foil tape, but be sure not to cover any valve or pipe openings. For the pipes, you can use fiberglass wrap or foam insulation. By adding a layer of insulation to your water heater, you’ll keep the warmth from escaping into the air and you’ll protect the machine from condensation in the summer months. 

5. Insulation. Most homes simply do not have enough insulation in the walls and attic, which is probably the number one contributor to sky-high energy bills. Insulation acts as a barrier against heat flow, helping to keep the warm air inside the house by slowing the flow and stopping the heat from getting outside. The United States Environmental Protection Agency says that with proper insulation, the average home in our area can save approximately 16 to 50 percent in total heating and cooling costs depending on the age and condition of the home. Plus it’s one of the highest rated home improvements in terms of real estate resale value.
