Ventilation is Key To Your Home's Health

I’m not shy about educating my readers on the importance of proper insulation in a house. But even if you’re one of only 20 percent of homeowners I meet with the right amount of insulation, chances are you’re still missing a key piece of the puzzle. The critical component is ventilation and not enough of it can be harming both your home and your personal health in more ways than you think. 

In the winter, we crank up the thermostat, sending more heat into our homes than any other time of year. We all know that heat rises, which means a lot of what we’re pumping into the house will quickly find its way through the ceiling and into the attic. Think about when you’re in a car and the windows fog up. What do you do? Usually, you’ll increase the airflow either by using the vents or just cracking a window. A house works much the same way, except that if you don’t have air flowing inside the attic, the heat and moisture just gets stuck there. If the attic is very warm, that moisture will develop into mold and mildew which can feed on your insulation and rot the wood. If the attic is cold enough, the moisture will freeze into little domes or even icicles until the temperature rises enough for the water to thaw and then be absorbed into all the places that it shouldn’t. Neither is a good scenario.

So what’s the best way to protect your home? Start by investing in a humidity gauge that measures water vapor in the air. A comfortable humidity reading is 30%-60%, but 45%-55% is an ideal level to maintain. If you’re seeing higher than 60% humidity in any area of your home, it’s going to be susceptible to mold, mildew, and bacteria growth.

Remember, attic ventilation allows your house to “breathe” so you want to balance your intake and exhaust to ensure that what is coming in is going out equally. The best ventilation system will include soffit vents that are installed underneath the overhang of the roof and take in the air and ridge vents that are installed at the top of the roof for the hot air to escape. For this method to work efficiently, all louvered vents must be sealed off and you have to ensure that your insulation isn’t blocking the airflow. Believe it or not, most roof manufacturers will void the warranty if a proper ventilation system is not installed. Luckily, new roofing technology enables contractors to add intake ventilation directly into the roof as opposed to using soffit vents, so if you’re in the market for a new roof, be sure to ask for that option. 

It’s important to note that homes have different characteristics and what works well for one may not work well for another. With the right balance of air, homeowners can optimize their roof and maintain the overall health of their home and their families. Remember, it’s always a good idea to get advice from a professional before taking on a big remodeling project.

Keep Winter Energy Bills in Check With These Tips

Outdoor lights, Christmas trees, and colder temperatures mean that December is usually one of the most expensive months in terms of utility bills. But with the holiday season behind us, January is a great time to take a closer look at how much energy you’re using and address the issues in your home that are causing high and unnecessary costs.

One resource that not enough people take advantage of is an energy 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. I’m happy to see that home inspections have resumed and inspectors are abiding by all COVID-19 safety protocols. 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 warmer 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. 

Happy New Year Everyone! Here’s to a warm, healthy and safe 2021!

Be Aware of Ice Dams After a Major Winter Storm

With our first official storm in the books, now is a perfect time to talk about how dangerous winter weather can be for your house. We all know that major snowfall, freezing rain, and sleet make for icy conditions on sidewalks and in your driveway, but what about on your roof? Sure, icicles might look pretty, the ice dams creating them can result in major leaks in your attic, ceiling, and interior walls.

An ice dam forms when heavy snow blankets the roof, forming an extra layer of insulation. As warm air rises from your house and up through your attic, it causes the layer of snow closest to the roof to melt and the water to slide down into the gutters. This would normally be a good thing, but because so many homes in our area aren’t properly insulated, what often happens is that the melting water hits the cold eaves of the roof, freezing again instead of draining off through the gutters. This forms an ice blockage. As that ice grows and grows, the water has nowhere to go so it starts to move under your roof shingles and eventually into your insulation and drywall. This is when you’ll start to see the leaks in your ceiling and walls.

The best way to avoid this problem is by taking preventative measures. I get calls from homeowners to remove ice dams after every winter storm, and for many, it is too late and they are already facing thousands of dollars worth of damage. But if you’re lucky enough to catch an ice dam before it fully forms, it’s a smart idea to get rid of it as quickly as possible.

Firstly, when you’re clearing snow from your driveway and sidewalks, think about your roof too. Removing snow from the house is the best way to protect your home against ice melting and refreezing in the gutters and up the roof. If you already have an ice dam forming, you can use a hammer and chisel to get rid of it, but be very careful as roof shingles are more delicate and brittle in cold conditions. One safe home remedy is to fill a pair of pantyhose with ice melt and lay it across the ice dam so the water will melt into the gutter. If you’re not comfortable on a ladder, call a professional to help you get rid of the ice dam quickly and safely.

These, of course, are just stop-gap measures. The only way to prevent ice dams from forming permanently is to have your home properly insulated and ventilated. More than 75% of homes in our area are under-insulated which causes the heat from your home to shoot right through the roof. Having appropriate insulation and ventilation will keep your home free from ice dams and will keep you much more comfortable in both the winter and the summer. You’ll feel the difference immediately, and you’ll see the benefit in your energy bills too. 

To all of my readers, may you have a wonderful Christmas and holiday season. I look forward to seeing you in the New Year.
