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.

Sealing Your Attic Hatchway

Most homeowners don’t realize that the pulldown attic stairway is one of the biggest heat loss culprits in the house. Many of us don’t go up into the attic very often other than to get holiday decorations from storage or maybe grab the suitcases for an upcoming vacation. Because we don’t access the attic all that much, we often don’t realize how much the temperature up there fluctuates and how much heat and air conditioning we are losing through the space. 

I can’t tell you the number of times that I have gone into an attic to find frozen water droplets on the tips of the roofing nails. Because homes are underinsulated and underventilated, the attic gets very hot in the summer and below freezing in the winter. Condensation and moisture can become a major problem, causing rot in the wood and mold on soft surfaces. 

But then of course there is the heat loss issue. We all know that heat rises and because most Connecticut homes are majorly underinsulated, we end up losing tons of warm air through the attic hatch. Plenty of people use draft strips and different kinds of sealant on doors and windows, but this entry point is almost always overlooked even though it’s the most important. The same goes for whole-house fans.

One of the common solutions we always recommend is installing an insulated box to cover the attic entryway or a built-in house fan. An insulated box is made from heavy-duty insulation and sealed with expanding foam. The box sits on top of the stairs when they are folded inside the attic, creating a barrier that still allows the homeowner to access the space as they need to. This simple structure reduces the amount of heat loss seeping from the living space of the home, making for a much more comfortable and energy-efficient environment. 

I always recommend that homeowners have their insulation and ventilation checked to keep their homes healthy, reduce their energy bills, and live more comfortably. While insulation is a very cost-efficient and easy home improvement, an insulated box is an excellent solution to achieve some of the goals of an insulation-optimized house for just a few hundred dollars. You’ll be shocked at the difference it makes.

Get Your House Ready for Winter

With the forecast settling into chillier temperatures, it’s time to talk about getting our homes ready for the cold before the thermometer drops below freezing. After all, there’s nothing worse than not being ready when the first proper snowfall comes our way. So without further ado, here are my top five tips for pre-winter preparation at home:

Take a picture of your roof.

We’ll start with an easy one. Go outside and snap a photo of your roof from each direction. Wondering why? When we get a massive snowfall, I usually recommend that people get their roofs shoveled. Removing the snow helps to reduce the risk of leaks and other damage to your home. But when the snow is very deep, it’s impossible to see the pipes, skylights, and other parts and pieces that stick up out of the roof. Keeping a picture of the clean surface is a great way to minimize the probability of an accident when you’re trying to prevent damage in the first place.

Stake the driveway.

Speaking of damage prevention, stop by the local hardware store and get some property markers. They are generally made of wood or metal and are sometimes painted in a fluorescent color. Use the markers to create an outline around your driveway. Just like your roof, when a blanket of snow hits, it’s impossible for a removalist to see where the driveway ends and where your lawn begins. Creating that parameter will help the plow truck driver know where to go, which should assist in keeping your curbs and grass intact.

Check your heat and air sources.

Don’t wait until you really need heat to make sure that everything is in working order. Clean or replace your HVAC filters and check the temperature gauge to make sure you can power up and down with no problems. If you haven’t already, now is definitely the time to remove those window A/C units and check and clean those filters too. While you’re at it, make sure your carbon monoxide detectors are working and change the batteries if necessary.

Seal up leaks.

I get calls all winter long from people who are wondering why their house is so drafty. If you have an attic hatch, install an insulated box to prevent the cold air from coming down into your living space. Check all your windows and doors for gaps and use weatherstripping, foam, or insulation to seal them tight. If you have a fireplace that you don’t use, get that covered too. Any passageways from the inside to the outside can act as wind tunnels when the frigid winter air comes calling.

Clean those gutters.

If your gutters are full of autumn leaves and debris, it will prevent winter water from flowing off the roof and down away from the foundation. If water has nowhere to go, it will refreeze in your gutters and at the base of your roof, resulting in dangerous ice dams and potential leaks. If you don’t want to do this dirty job yourself, schedule a pro to handle it for you. It will be worth it.

If you do just these five things, you’ll be in much better shape when the wicked weather decides to settle in. Plus it’s much more pleasant to get these jobs out of the way before it’s too cold and snowy to bother. Happy Thanksgiving!
