Waterproofing Your Chimney

With recent summer rainstorms bringing unexpected downpours, homeowners need to pay extra attention to their chimneys. A chimney can be a hidden source of leaks and damage if not properly maintained. Waterproofing your chimney is essential to protect your home from moisture damage, ensuring it remains safe and sound throughout the year. Here’s a step-by-step guide to help you waterproof your chimney effectively.

Why Waterproof Your Chimney?

Chimneys are exposed to the elements year-round, making them susceptible to water damage. Bricks and mortar can absorb water, leading to deterioration over time. This process can cause cracks, spalling (flaking of the brick surface), and even structural damage. Waterproofing your chimney not only prevents these issues but also extends its lifespan, saving you money on potential repairs.

Assess the Current Condition

Before you begin waterproofing, inspect your chimney for any existing damage. Look for cracks, loose mortar, or spalling bricks. If you find significant damage, it’s best to have a professional mason repair these issues before proceeding with waterproofing. Minor cracks and gaps can be filled with a high-quality chimney sealant.

Clean the Chimney

A clean surface is crucial for effective waterproofing. Remove any dirt, moss, or debris from the chimney using a wire brush and a garden hose. For stubborn stains, a mild detergent solution can be used. Ensure the chimney is completely dry before applying any waterproofing products.

Choose the Right Waterproofing Product

There are various waterproofing products available, but not all are suitable for chimneys. Opt for a breathable, water-repellent solution designed specifically for masonry. These products allow water vapor to escape from the brick while preventing liquid water from penetrating the surface.

Apply the Waterproofing Solution

1. Preparation: Wear protective gloves and eyewear. Cover the surrounding area to protect it from overspray.

2. Application: Using a pump sprayer or a paintbrush, apply the waterproofing solution evenly across the entire chimney surface. Start from the bottom and work your way up to ensure complete coverage. Be generous with the application, but avoid over-saturating any area.

3. Second Coat: After the first coat has dried (usually within a few hours, depending on the product), apply a second coat for added protection.

4. Drying Time: Allow the chimney to dry thoroughly. Check the manufacturer’s instructions for specific drying times, but typically, it takes about 24-48 hours for the solution to cure completely.

Regular Maintenance

Waterproofing is not a one-time fix. Inspect your chimney annually, especially after heavy rainstorms, to ensure the waterproofing is intact. Reapply the waterproofing solution every 5-7 years, or as recommended by the product manufacturer.

Waterproofing your chimney is a straightforward task that can save you from costly repairs and headaches down the line. However, this project should only be done if you’re completely comfortable on a roof and using a ladder. If this kind of home maintenance task isn't something you do regularly, it’s a good idea to call a professional. No home improvement job is worth a trip to the emergency room.

Tackling Summer Window Condensation

You’ve probably noticed those pesky water droplets forming on your windows as summer humidity rises. It’s not just an eyesore—it can also be a sign of underlying issues within the home. 

Condensation occurs when warm, humid air comes into contact with a cooler surface—like your window glass. During summer, the air inside your home is usually cooler (thanks to your trusty air conditioner) while the air outside is hot and humid. This temperature difference causes moisture to condense on the cooler inside surface of your windows. Here are a few reasons why you might see more condensation:

1. High Humidity Levels: Summer air can hold a lot more moisture, especially in places like Connecticut where it's humid in the summer and dry in the winter.

2. Poor Ventilation: Without proper airflow, moisture has nowhere to go, leading to higher humidity inside your home.

3. Inefficient Windows: Older or single-pane windows might not provide the best insulation, causing the inside surface of the glass to get cool enough for condensation to form.

Why is condensation a problem? While a bit of condensation might seem harmless, it can actually lead to a few issues, such as:

• Mold and Mildew: Excess moisture can create the perfect environment for mold and mildew, which can damage your home and harm your health.

• Damage to Windows and Frames: Prolonged exposure to moisture can warp or rot wooden frames, damage seals, and reduce the lifespan of your windows.

• Reduced Visibility: Condensation can make it difficult to see clearly through your windows, affecting your view and natural light.

Now that we know what’s causing the problem, let’s dive into some solutions. Here’s how you can reduce and even prevent condensation on your windows:

1. Improve Ventilation: Make sure your home has good airflow. Use exhaust fans in kitchens and bathrooms, and consider a dehumidifier if humidity is a persistent problem. Opening windows when it’s not too humid outside can also help.

2. Upgrade Your Windows: If you’re still dealing with single-pane windows, it might be time to upgrade. Double or triple-pane windows with insulating gas between the panes can significantly reduce temperature differences and condensation.

3. Seal Leaks: Check for and seal any leaks around your windows and doors. This can help keep humid air outside where it belongs.

4. Use Blinds and Drapes Wisely: While it’s tempting to keep blinds and drapes closed to block out the sun, this can actually trap heat and humidity. Try to keep them open when possible to allow air to circulate.

5. Maintain Indoor Plants: Houseplants are great, but they can add to indoor humidity. If you have a lot of plants, consider moving some outside or to a well-ventilated area.

6. Regular Maintenance: Keep your windows in good shape by regularly checking seals, cleaning them, and ensuring there’s no damage to the frames or glass.

Remember, a little attention goes a long way in keeping your windows—and your home—in great shape. Stay cool and dry this summer!

Keep Your Home Cooler with These Tips

When the weather gets too hot to handle, many homeowners simply crank up their air conditioning to stay comfortable. But what people may not realize is that the combination of cold air and high humidity could lead to leaks. So what can you do to stay cool without putting your home at risk? Here are some tips: 

Keep the filter clean. 

A dirty filter can cut your air conditioner’s efficiency in half, so be sure to replace or wash it at least once a month during the summer. Not only will a clean filter enable more cold air to come through the unit, but it will also decrease the amount of pollen, dander, and even mold that you could be breathing in. Many people don’t know that air conditioning units are rated by their MERV, which stands for minimum efficiency reporting value or, more simply, the effectiveness of the filter. MERV ratings are between one and 20, with most home air conditioning units rating between one and 12. If you’re in the market for a new filter, choose one at the top of the scale as it can trap smaller particles and protect your home from mold spores, dust mites, and other nasty contaminants. 

Make sure your windows are leak-free. 

Window A/C units are tough to fit and often result in large gaps where the hot air outside can come in. Make sure all the space around the air conditioner is sealed up tight with foam for bigger gaps or simple foil tape for smaller areas. The materials you’ll need can all be found at the local hardware store and you’ll be shocked by the difference in air temperature by just plugging up those holes. 

Run the unit on a timer.

There is no point running your A/C on high when you’re at work or away for the weekend. A digital timer will lower the unit’s output when you’re not at home, and then bring the house to a comfortable level by the time you walk in the door. By programming a timer to your preferences, you can lengthen the life of the unit and lower your energy bills without noticing a difference in the level of comfort. If you don’t rely on Alexa, you can buy a smart plug for your outlet to control your A/C from your phone.

Up your insulation.

If your attic isn’t properly insulated, it’s going to be a sauna up there. You don’t even need to go up to check - you can tell simply by touching your ceiling. If it feels hot, then imagine how hard it is for a window unit or even central A/C to compete. A well-insulated and ventilated attic will ensure that hot air can escape while keeping cool air circulating in the living areas of the home. Plus, proper insulation comes in mighty handy during the cold months of the year. 

Watch for leaks. 

Central air conditioning units are notorious for leaks for three reasons: a cracked or broken drain pan, a clogged air filter, or a plugged-up condensate line. If water can’t drain properly, it will end up in your ceiling or walls which can cause serious and expensive damage. If you see even the smallest leak, shut down the unit and inspect these three areas. A simple fix might save you thousands in damage if you act quickly.
