Attic Moisture Can Lead to Major Damage

As summer humidity begins to ramp up, it’s important to pay special attention to one of the most neglected areas of the home. Your attic can hold a lot of moisture and if it’s not insulated and ventilated correctly, that means major issues for you, the homeowner. In this two-part series, we’ll discuss how moisture can accumulate in the attic and what you can do to protect your home from serious damage. Let’s kick things off with a list of the major moisture-conducting culprits:

1. Insufficient ventilation: Without proper airflow, moisture from the living spaces below can become trapped in the attic, leading to condensation and elevated humidity levels.

2. Roof leaks: Damaged or deteriorating roofing materials can allow water to enter the attic during rain storms or snowmelt. Roof leaks can be caused by missing or cracked shingles, damaged flashing, or compromised roof seals.

3. Plumbing leaks: Plumbing pipes that run through the attic can develop leaks over time. Even a small drip or a slow leak can contribute to moisture accumulation in the attic.

4. Inadequate insulation: As hot and cold air collide, they will condensate or freeze. Without proper insulation and temperature regulation, it’s much easier for moisture to accumulate.

5. Blocked vents: Blocked or obstructed attic vents can impede proper airflow, preventing moisture from escaping. This can result in increased humidity levels and potential condensation problems.

6. Misdirected exhaust fans: If bathroom or kitchen exhaust fans are not vented directly outside, they can introduce warm, moist air into the attic space. This can cause condensation and moisture-related issues.

7. Poorly sealed attic access points: Gaps or insufficient sealing around attic access points, such as doors or hatches, can allow humid air from the lower floors to enter the attic, leading to moisture buildup.

8. Insufficient vapor barrier: A vapor barrier is a layer designed to prevent moisture from passing through walls and ceilings. If there is an inadequate or damaged vapor barrier in the attic, it can allow moisture to penetrate and cause problems.

It's important to address any water issues in the attic promptly to decrease the chances of mold growth, wood rot, or structural damage. Because most people access their attic infrequently, problems often don’t go detected until water starts showing up on the ceiling. Next week we will highlight several ways to protect your home from moisture before it's too late.

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.

Window Condensation? A Common Spring Problem To Resolve

This week a reader asked a great question, “My windows are constantly fogged up and I’m not sure why. How can I fix them?”

Window condensation is such a common problem and it happens in homes with too much humidity. If your house is old or new, it doesn’t matter. When the humidity inside the home is higher than the humidity outside, your glass windows and doors will start to show condensation, especially at this time of year when evening temperatures hover around 40 degrees.

Homes should be at about 50 percent humidity. When they are higher, the glass in your home will act as a dehumidifier and the excess moisture will collect on it in an attempt to get rid of the water from the air. Newer homes are built tightly, which makes it harder for moisture to escape. Older homes can let too much moisture from the outside in. This is why condensation doesn’t discriminate. It can happen to any house.

So what can you do to either prevent condensation or get rid of a problem that you already have? Step one is to purchase a hygrometer which is the instrument to measure humidity. As I said, 50 percent humidity inside the home is what you’re aiming for, but anything from 45 to 55 percent is fine. If your hygrometer is measuring 60 to 70 percent or higher, you’ll want to take immediate action. While condensation on windows is unsightly and annoying, mold and mildew growth is much worse.

If you have condensation, here are a few ideas to get rid of it quickly and effectively.

Turn Down Your Humidifier. If you’re using one, it’s working! By releasing less moisture into the air, you’ll reduce your condensation problems.

Buy a Dehumidifier. If your house is constantly damp, a moisture eliminator is going to be crucial. Lots of homeowners run dehumidifiers in their basement all the time but keeping one going upstairs might be necessary. If you are running slightly more humid in rooms such as the bathrooms or the laundry room, try a refillable moisture absorber such as DampRid.

Use Your Fans. Bathroom and kitchen fans are there for a reason. Cooking a dish that lets off lots of steam or taking long showers both create tons of extra water. Extractor fans can help to remove that moisture. Let them run for 10 minutes after use.

Open the Windows. Air circulation is key, so open up those windows and make good use of ceiling fans. Also, make sure you check the humidity in the attic, as heat tends to rise. You may find that your first and second floors have entirely different humidity levels and need to be treated independently.

Insulate! Because condensation is caused by heat and moisture, it’s a good idea to make sure your home is insulated to make the air easier to control. Insulation can be as simple as weatherstripping and door sealing depending on the level of wall and attic insulation in your home. If you’re not sure how much insulation you have, call a contractor to give you an assessment and free quote.

Spring and summer are much wetter seasons than fall and winter, so be sure to check your moisture levels often. As the humidity rises outside, a house that doesn’t “breathe” properly will be susceptible to a number of problems. Consider foggy windows as a warning sign and take action right away to avoid potentially expensive repairs and hazardous breathing conditions in the future.
