Summer Humidity Can Cause Problems in the Home

Even with all this rain, it won’t be long before summer weather is in full swing.

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

Many 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 a much smarter option.

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 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 likely help regulate the rest of the house.  

One way to know if your house holds 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. 

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.

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 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. Also, 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.

Finally, if you have a dehumidifier, be sure to keep the filter clean. Dust, dirt, and debris can build up, 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.

Mold in the Home: A Common Problem in Spring 4-4-24

Mold is an issue that most homeowners have to deal with at one time or another. It’s the damaging by-product of excess moisture that can wreak havoc on your home, and more importantly, your health. With spring in full swing, now is a good time to inspect your house for mold and get rid of it before it does any kind of serious damage. 

You might be familiar with mold or mildew from your shower or bathtub. Since the shower is often wet and the tiles are waterproof, water can sometimes seep into the grout. If the grout is old and can’t handle its repelling duties properly, it becomes a breeding ground for mildew which can generally be cleaned with a good scrub. But what happens when mold starts to grow in the places you can’t clean as easily – places like your ceiling, inside your walls, or in the attic? You’re probably saying, “Not in my house”. Well, guess again.

At least half the homes I visit for remodeling projects have a major mold problem and the owners don’t even know it. How? Because mold generally grows in places that you can’t see – like inside the walls and in the attic. What most people don’t realize is that mold reproduces by releasing spores that you’re breathing in day after day.

How common is this? If you’ve ever had a leak, you’ve most likely had a mold problem. So what can you do about it? You can prevent mold by ensuring your home stays dry. Here are my top tips:

1. Keep your gutters and downspouts clean and clear so water can drain away from the foundation of your house. 

2. Make sure the ground around your house doesn’t slope inward towards the foundation where water can idle.

3. Don’t let a leaky roof go unfixed.  Get it patched up immediately and ask your contractor to inspect for any mold growth.

4. Inside the house, beware of any discoloration on the ceiling.

5. Ensure high moisture areas like bathrooms are well-ventilated with good ceiling fans that don’t vent into the attic.

6. If a leak happens in a carpeted area, don’t just leave it to dry. A damp area can attract mold in less than 48 hours.

7. Ensure large appliances such as refrigerators and washing machines have a catchment tray in case of a malfunction.  

8. If you think your house or basement is susceptible to high moisture, consider purchasing a dehumidifier to regulate the humidity and remove any excess moisture from the air.

If you’ve had a mold problem that you’ve tried to control by scraping, cleaning, and repainting the area, don’t make the same mistake twice. If the mold keeps coming back, that means the issue runs deeper than the eye can see. It’s time to call in the pros.

Protecting Your Home From Attic Moisture

If your attic holds a lot of moisture, it can cause a lot of problems for the health of your home. Last week we took a deep dive into the most common culprits of humidity and this week we’ll be talking about how to remedy those issues. To get rid of moisture in your attic, you'll need to identify and address the underlying causes. Here are some steps you can take:

1. Find the source: If your attic humidity level is high, first determine what is causing the excess moisture. The most likely culprits are inadequate ventilation and insulation, roof leaks, or a plumbing issue.

2. Improve ventilation: Most houses that I visit do not have enough ventilation. It’s truly the best way to reduce moisture buildup and keep the temperature in your home more regulated year-round. 

3. Look for air leaks: Check for any gaps, cracks, or openings that might be allowing warm, moist air from your home to enter the attic. Seal these leaks with caulk or weatherstripping to prevent the transfer of moisture. It will also help if critters tend to find their way into the attic.

4. Insulate properly: Insulation helps regulate temperature and prevent condensation. Ensure your attic is adequately insulated to minimize temperature differences between the interior and exterior. Insulation is not just helpful for the winter months, it’s actually crucial year-round.

5. Assess for roof leaks: Inspect your roof for any signs of leaks or damaged shingles or if you’re not comfortable on a ladder, contact a professional. They will inspect both in interior and exterior of the home and be able to advise on appropriate repairs or replacements.

6. Address plumbing issues: If there are plumbing pipes or HVAC ducts running through your attic, check for any leaks or condensation. Repair any leaks and insulate the pipes or ducts to prevent moisture buildup.

7. Control humidity levels: Excessive humidity in your home can contribute to attic moisture problems. Use dehumidifiers in areas with high humidity, such as basements or bathrooms, to control moisture levels. Additionally, ensure your kitchen and bathroom vents are properly vented to the exterior, not into the attic.

8. Monitor and maintain: Regularly inspect your attic for signs of moisture or mildew. If you notice any issues, promptly address them to prevent further damage.

Attics are always tricky because they are so rarely occupied. However, if humidity levels increase the moisture will become a mold problem very quickly, which is hazardous to both your home’s health and yours. When in doubt, always contact a professional for guidance. A licensed contractor will be able to help remediate any problems both in the short and long term.
