Understanding Indoor Air Quality During Winter

As winter tightens its grip, homeowners often seal their residences to keep the cold at bay. While this practice conserves heat, it can inadvertently compromise indoor air quality, leading to discomfort and potential health issues. Understanding the challenges and implementing effective strategies can ensure your home's air remains fresh and healthy throughout the colder months.

Understanding the Winter Air Quality Challenge

During winter, increased use of heating systems and reduced ventilation can lead to a buildup of indoor pollutants. Common culprits include dust mites, pet dander, mold spores, and volatile organic compounds (VOCs) emitted from household products. Exposure to these pollutants may cause symptoms like headaches, dizziness, and respiratory issues, often referred to as "sick building syndrome."

Effective Strategies to Enhance Indoor Air Quality

1. Regular Ventilation: Even in cold weather, it's essential to allow fresh air to circulate. Briefly opening windows or doors can help disperse indoor pollutants. Utilizing exhaust fans in kitchens and bathrooms further aids in expelling contaminants. 

2. Maintain Optimal Humidity Levels: Aim to keep indoor humidity around 50%. Excess moisture fosters mold growth, while overly dry air can irritate respiratory passages. Using humidifiers or dehumidifiers as needed can help maintain this balance.

3. Regular HVAC Maintenance: Ensure your heating system is serviced annually. Clean or replace filters every 1-3 months to prevent dust and allergen accumulation. Consider having your air ducts inspected and cleaned to remove any built-up debris that could circulate throughout your home.

4. Consider Using Air Purifiers: Air purifiers can be a powerful tool in maintaining indoor air quality during winter. Look for models equipped with HEPA (High-Efficiency Particulate Air) filters, which are designed to capture small particles like dust, pollen, and pet dander. Many purifiers also include activated carbon filters to remove odors and VOCs from the air. Placing a purifier in frequently used spaces, like the living room or bedroom, can significantly reduce airborne pollutants and help create a healthier home environment.

5. Incorporate Indoor Plants: Certain houseplants can naturally purify indoor air by absorbing toxins and releasing oxygen. Plants like sansevieria (snake plant) are known for their air-cleaning properties and can be a beneficial addition to your home with very low maintenance needs.

6. Use Natural Cleaning Products: Traditional cleaning agents can emit VOCs, degrading air quality. Opt for natural or eco-friendly cleaners to minimize chemical exposure. Additionally, store chemicals safely and ensure proper ventilation when using them.

7. Monitor for Radon and Carbon Monoxide: Install detectors to monitor levels of these colorless, odorless gases. Regularly test and maintain these devices to ensure they function correctly, safeguarding your household from potential hazards.

8. Keep Your Home Clean: Regular dusting and vacuuming can significantly reduce indoor pollutants. Using a vacuum with a HEPA filter ensures that dust and allergens are effectively captured and not redistributed into the air.

9. Be Cautious with Scented Products: Air fresheners and scented candles can emit VOCs. Opt for unscented or naturally scented alternatives, and ensure proper ventilation when using them.

By implementing these strategies, you can maintain a healthy indoor environment during the winter months, ensuring that your home remains comfortable and safe.

Save On Energy Costs with This Home Improvement

With the leaves falling and winter weather knocking on our doors, there is no better time to start preparing the house for what will probably be a very expensive winter if your house isn’t insulated.

I’ve been in the attics of thousands of homes in this area and I can tell you that 75 percent of them aren’t insulated the way they should be. Insulation acts as a barrier, helping to keep warm air inside the house by slowing the flow and stopping the heat from getting outside. The problem is that most homes, especially older ones, do not have enough insulation to keep up with our cold winters. In fact, many homes around here have barely enough insulation to withstand the cold months in Florida. 

So, how do you know if you have proper insulation? You’ll need to find out where you currently have (or don’t have) insulation, what type of insulation is installed, and what its “R-value” is. The R-value is the materials’ resistance to heat flow, so the higher the R-value, the greater the insulating properties. Once you have this information, you can determine how much additional insulation you need, which will be dependent on our Connecticut climate, your house size, and what kind of heating you have. This analysis can either be done by a qualified contractor or you can do it yourself if you’re comfortable working in the attic.

Once you determine what you need, there are two popular ways to get insulation into your home. A licensed contractor can either blow loose fiberglass under the floor in the attic or batts can be laid between the floor joists. There are pros and cons to each option and they depend on the size of the house, the clearance space, and what the attic is used for. I install insulation both ways and one is just as effective as the other - the best method is the one that works for your home.

The bottom line? The United States Environment Protection Agency says that with proper insulation, the average home in our area can save approximately 16 percent in total heating and cooling costs. For older homes, that number skyrockets to nearly 50 percent. What’s even better is that insulation almost always recoups its value when a house hits the real estate market.

So is it worth taking a look at insulation? If you like keeping more dollars in your wallet, I’d say yes.

Warped Siding is a Common Problem

A question I get from readers time and time again is about vinyl siding that looks “wrinkled” even when it’s new. Many people think warped siding is an environmental problem and that too much sun and heat or even the contrasting winter cold is what’s creating the damage. Little do they know that warping has very little to do with the weather and a whole lot to do with how it’s put on the home.

Let’s start with the real name of the problem. Siding that is wrinkling or warping is actually called “oil canning” or “stress buckling” and it happens when the siding isn’t installed properly.

All homes are made of natural materials such as wood, which expand and contract with seasonal changes. People love vinyl siding because it’s very low maintenance and offers fantastic curb appeal, but a DIY or inexperienced install can actually make a house look much worse, even with very new siding. 

Every house needs to expand and contract. While it might seem logical to nail vinyl siding tightly to make sure it doesn’t come loose, doing so will actually cause the panel to buckle because it can’t “breathe” with the house. That’s why most vinyl siding panels come with longer nail slots instead of small holes. It gives everything room to move and shift. 

Another possible siding installation pitfall is leaving too much overlap between panels. While you might think this creates a stronger bond, it actually restricts movement, causing the siding to stretch and then buckle in the same way.

Back to my reader’s question. Is there ever a time when the sun might cause siding to warp? The answer is not really, although I have seen damage from sunlight reflecting off an adjacent window. The only other thing that could cause an issue is your gas grill, so keep it far away from the house.

Once oil canning happens, the siding has to be replaced. Because the issue is installation, the product’s warranty is worthless and the manufacturer isn’t going to be responsible for the defect. While removing panels is pretty straightforward, it can be tough to get a color match if the siding is a bit older. 

These are all the reasons why it’s so important to work with a contractor who knows what he or she is doing. If you’re going to tackle this job on your own, make sure you do your research and know all the common mistakes that can be made. You don’t want all that hard work to result in a home aesthetic that’s anything less than perfect.
