Waterproof Your Chimney Now to Avoid Costly Repairs Later

You may have never thought about exterior chimney maintenance unless you’ve had a problem, but because chimneys come up above the roof line, they are more susceptible to harsh weather than any other part of your home. That’s why spending a little time and money to waterproof and protect the area can save you thousands of dollars and plenty of potential headaches down the road.

If you plan on waterproofing your chimney, the first thing you’ll have to do is measure the surface area. Take care to measure all sides and add the measurements together to find the total surface area. This will help you to determine how much material you will need.

Now, it’s time to clean. Your chimney will most certainly have mold, dirt, rust, and stains on it, and you’ll want to remove them before starting the waterproofing process. I like Chimney RX Safer Brick and Masonry Cleaner which you can use instead of muriatic acid for the same cleaning power without the harsh fumes or risk of burns. Applying the solution is easy: just use one part cleaner with four parts water and apply to the area with a pump sprayer. You can then either scrub the surface or use a power washer to remove the debris. Let everything dry for at least 24 hours before moving on to the next step.

Next, you can start to prepare the area for any potential repair work. You don't want to damage your roof and shingles when waterproofing your chimney, so use a canvas drop cloth to cover the area as plastic can get very slippery. Make sure to cover over any windows or skylights that are in reach as well. Once waterproofing overspray has been applied, it will be incredibly difficult to remove.

If you have minor cracks in the chimney, now is the time to fill them. Chimney RX makes a Masonry Crack and Joint Sealant that works really well on small cracks up to one-eighth of an inch. It simply paints on and then dries a milky white color. However, if you have larger cracks or if you need any part of the chimney rebuilt or tuckpointed, I highly suggest calling a professional to manage the repair.

Once minor work has been completed, you’re ready to apply the waterproofing agent. Again, ChimneyRX makes a great product for the job. No matter what you use, be careful. Most people don’t realize that there is a difference between water repellent and sealant. A sealant will form a hard surface, trapping water inside and making the area susceptible to leaks, whereas a repellent will still enable the porous bricks to breathe and move the way they are supposed to.

Applying the sealant is as easy as the cleaning step - all you’ll need is a pump sprayer with a fan nozzle. The product that you use will give instructions for the amount that you’ll need, so just go by your surface area and the directions provided. I always suggest starting from the base and working your way up, applying heavy coats using a side to side spraying motion. Unlike painting, it’s a good idea to apply a “flood coat” first and then top it up with a second coat within just a few minutes to even it out. For areas that feel oversaturated, have a soft bristle brush handy. Also, be sure you’re working in good weather - while waterproofing products do dry quickly, you’ll want to give them a good six hours in the sun to fully set before a bout of bad weather.

Finally, just like any job on a roof, please make sure you’re comfortable with heights and working from a ladder before you tackle this project. The last thing we want us a trip to the emergency room from a nasty fall. When in doubt, always hire a pro to tackle the job.

Don't Be the Coldest House on the Block This Winter

I love winter. You’ll often find me skiing, playing ice hockey on one of our local ponds, and hiking in the snow over the next several months. But for all the fun that winter has to offer, one thing I can’t stand is coming home to a cold house.

During this week’s delayed winter weather, I got tons of calls from people all over town asking what can be done about their drafty, cold homes. They are also concerned why their houses are so hard to heat and their energy bills are through the roof. The answer to their question is easy because the problem can be found in three-quarters of the homes I work on in our area. The culprit of cold is a major lack of insulation.

Insulation is a cotton-looking fiberglass material bundled in pink or yellow colored rolls that you may have seen in your attic or behind the wall of new construction. It also comes in what we call “loose fill” which can be blown into harder to reach areas. Contractors use insulation between walls, in attics and in basements to retain heat in the house in the winter and keep the heat from getting into the house in the summer. The amount of insulation needed for a home is measured by its R-Value, which equates to its resistance to heat moving through it. Simply put, the higher the R-Value, the better the insulating properties.

Back 50 years ago when many of the homes in Central Connecticut areas were built, R-Value wasn’t a popular unit of measurement. Instead, the industry kept it simple and measured insulation by its thickness in inches. When a home was constructed, the contractor would put about three inches of insulation into the attic, if any was used at all. Three inches of insulation would give that homeowner an R-Value of about R-10. According to EnergyStar, homes in our area should be fitted with insulation that measures between R-49 and R-60. So if you have a home from the 1950s or early and have never upgraded your insulation, your home is definitely not equipped to handle our harsh Connecticut winters.

Do yourself a favor and take a trip up into your attic. Chances are your insulation isn’t up to scratch and it’s probably time for an upgrade. As a general guideline, insulation with an R-Value of between R-49 and R-60 will sit at between 19 and 22 inches thick when settled. How does your insulation stack up to that? If it doesn’t, you don’t have to worry - a contractor can install it in less than one day and insulation has one of the highest resale values of any home improvement job.

With any proper insulation job also comes ventilation, which allows air to move through the attic, preventing over and under heating and reducing the risk of mold buildup. We will talk about that in detail next week.

Don't Leave Roof Leaks To Wreak Havoc on Your Home

When rain comes like the forecast says it will, my phone starts ringing off the hook with calls to fix people’s leaky roofs. We had a dry autumn thus far, but as soon as the skies open up, the rain finds its way right into people’s homes, causing dark, damp spots on their ceilings and down their walls. With more rain in the forecast for this coming week, I wanted to address this common problem for homeowners and give you some advice to follow before the real wet and wild winter weather arrives.

If you find a leak, have it checked right away. Leaks show themselves in the walls and ceilings but it’s not always easy to find the source of the problem. Roof leaks generally only surface during bad weather and won’t cause issues when the sun is out, unlike pipe leaks can appear anytime.

To know for sure, grab a flashlight and head up into the attic. You can remove the insulation around the spot where the leak is staining the ceiling. Then look up at the pitch and see if you can see any holes or light shining through. Popular roof leak sources include valley flashing, gaskets around vents, or cracks and crevices around your chimney or utility entrances, but it’s tough to know without jumping up on the roof for an inspection which I’d leave to a professional.

If you call a contractor, he or she will want to thoroughly inspect the roof and the ceiling to find the cause of the problem. Often times they will find corrosion or lifted shingles, but in these conditions where we had a lot of leaves fall in a very short period of time, the problem could simply be coming from rainwater that can’t drain due to clogged gutters. Once the water path into the house is detected, a repair can be relatively simple, inexpensive, and might be fixed on the spot.

While many repairs are minor, it’s very important not to ignore the issue. Water traveling from the roof to the inside of your home has a lot to get through to finally appear in your ceiling, including layers of shingles, wood, and insulation. If the water sits stagnant, it becomes a breeding ground for mold growth which can deteriorate the materials that help your house stay strong. Mold can also be dangerous for your family to breathe in every day, and having it circulating through your home as you begin using your heating system can cause both short and long-term health issues, especially for young children and people with asthma.

Simply put, a roof leak isn’t something to mess with and even if it is a major issue, getting someone to give you options for dealing with it will help you plan for the work that may be inevitable. With more rain in the forecast this coming week and with winter on the way, it’s a problem that’s better for you to deal with now before it has the opportunity to get worse.
