Why Good Insulation is Key in the Summer Months

With a week of heat like the one we are having, homeowners with air conditioning have most certainly relied on its luxuries. But for all the comfort that cold air provides, running the A/C constantly over long periods of time can do a number on your energy bills. This is especially true if you live in a home with poor insulation. 

Most people think about the benefits of insulation during the winter but the truth is that a well-insulated home will benefit you all year round. As many of us know from school science class, heat rises, which is why the top floor and attic are always warmer than the bottom floor of a house. When an attic has no insulation, it will become significantly hotter than the outside temperature. Go ahead and touch the ceiling. If it feels warm, you can just imagine what the temperature is like above it. 

When your home doesn’t have enough insulation, those air conditioning units have to do double duty to regulate the temperature. Whether you have central air or window units, they are working overtime to keep you comfortable. All that extra effort gets reflected in your energy bills at the end of the month. 

There are several places where a home can get a boost in the insulation department. The attic is the place for the biggest improvement because it has the largest square footage and sees the greatest temperature changes. It’s also a place in the home that we tend to ignore because we’re not in there very often. Insulation options run from blowing loose fiberglass under the floor to laying batts between the floor joists. There are pros and cons to each option and they depend on the size of the house, the clearance space, and what the attic is used for. No matter which way you go,  a well-insulated attic is a pretty inexpensive home improvement and it will more than pay for itself in both energy costs and overall resale value.

In addition to the attic, ensuring that windows and doors are free of gaps and holes will help to keep your cold air inside. Check your door sweeps to see if they need replacing and seal any windows with caulk or sealing tape. Again, this is going to benefit your home both now and in the winter when you’re trying to keep the warm air in. 

Finally, for those of you with window A/C units, be sure to insulate around them. You can do this simply by using a flexible foam to get a good seal on the top and bottom of the unit. Also, those side curtains aren’t there for nothing. Make sure they are tight fitting and screwed in. They are there to help anchor the unit and keep the sides nice and secure. A window A/C that’s dropped in with no insulation is effectively only running at half power since so much of the cold air goes right back outside, so it’s worth taking the extra steps to do it right.

Ceiling Cracks - A Simple Problem?

This question from a reader might resonate with many of you. “Dear Bob, I noticed a ceiling crack has appeared in my bathroom ceiling near my shower. What should I do?”

I am so glad the reader asked this question because it's incredibly common and can easily happen in any home. The reason ceiling cracks appear is because the bathroom usually holds the most moisture in the house. If the bathroom doesn't have proper ventilation, water and steam from the shower can get trapped in the ceiling, softening the drywall and eventually cracking the paint. An easy cosmetic fix could be to fill in the cracks and repaint the ceiling, but my advice is to first check to ensure no leaks or drainage issues are causing the problem in the first place.

I spend a lot of time in attics and I often see bathroom fans that have been disconnected or knocked off track. So while they sound like they are working, they aren't actually extracting the moisture properly. First-floor bathrooms can be even more susceptible to cracking because of the possibility of plumbing leaks inside the ceiling that originate from an upstairs bathroom. 

So what can you do? If you fix the crack, you don't want it coming back again. Start by making sure you have no leaks or damage in your plumbing. If the area looks wet and doesn’t dry out after using the shower, it is likely an issue coming from inside the ceiling itself, in which case you’ll want to call a plumber. If the ceiling dries after each shower, it’s probably just an extraction problem.

Now have a look at your bathroom fan to ensure that it's working properly. If the fan is old, it's probably worth having it replaced. Older fans or ones that aren’t working well are leaving moisture in the air, which will crack your paint. A good fan should extract moisture in 15 minutes and should be directed outside, not in the attic. 

Once you're ready to patch and paint, make sure the surfaces are very dry and use a water-resistant compound and paint to repair the ceiling. Ensure you give the compound plenty of time to dry before painting - I recommend one day or more. Finally, make sure you're preventing any excess moisture build-up in the future by running the fan during and for 20 minutes after each shower. 

I love hearing from my readers, so please keep those questions coming!

Be Aware of Ice Dams After a Major Winter Storm

With our first official storm in the books, now is a perfect time to talk about how dangerous winter weather can be for your house. We all know that major snowfall, freezing rain, and sleet make for icy conditions on sidewalks and in your driveway, but what about on your roof? Sure, icicles might look pretty, the ice dams creating them can result in major leaks in your attic, ceiling, and interior walls.

An ice dam forms when heavy snow blankets the roof, forming an extra layer of insulation. As warm air rises from your house and up through your attic, it causes the layer of snow closest to the roof to melt and the water to slide down into the gutters. This would normally be a good thing, but because so many homes in our area aren’t properly insulated, what often happens is that the melting water hits the cold eaves of the roof, freezing again instead of draining off through the gutters. This forms an ice blockage. As that ice grows and grows, the water has nowhere to go so it starts to move under your roof shingles and eventually into your insulation and drywall. This is when you’ll start to see the leaks in your ceiling and walls.

The best way to avoid this problem is by taking preventative measures. I get calls from homeowners to remove ice dams after every winter storm, and for many, it is too late and they are already facing thousands of dollars worth of damage. But if you’re lucky enough to catch an ice dam before it fully forms, it’s a smart idea to get rid of it as quickly as possible.

Firstly, when you’re clearing snow from your driveway and sidewalks, think about your roof too. Removing snow from the house is the best way to protect your home against ice melting and refreezing in the gutters and up the roof. If you already have an ice dam forming, you can use a hammer and chisel to get rid of it, but be very careful as roof shingles are more delicate and brittle in cold conditions. One safe home remedy is to fill a pair of pantyhose with ice melt and lay it across the ice dam so the water will melt into the gutter. If you’re not comfortable on a ladder, call a professional to help you get rid of the ice dam quickly and safely.

These, of course, are just stop-gap measures. The only way to prevent ice dams from forming permanently is to have your home properly insulated and ventilated. More than 75% of homes in our area are under-insulated which causes the heat from your home to shoot right through the roof. Having appropriate insulation and ventilation will keep your home free from ice dams and will keep you much more comfortable in both the winter and the summer. You’ll feel the difference immediately, and you’ll see the benefit in your energy bills too. 

To all of my readers, may you have a wonderful Christmas and holiday season. I look forward to seeing you in the New Year.
