So, you’re finally getting around to preparing your home for the winter. Great!
Fall is an excellent time to be doing outdoor work. Not too hot, not too cold, and with the days getting shorter, darkness will force you to quit your tasks at a more reasonable hour, placing you safely in your slippers so that you may be fed and couch bound with a beer in your hand, well in time to catch the start of the hockey game.
What is the task at hand? To bolster our home’s system of defense. Who is the enemy? The demon is well known, and is the same, notorious culprit that’s been slowly destroying homes for years, that being water. It’s form? Rain, snow, sleet, or basically anything that pours or puddles. Strategy? To seal by means of a paint, caulking, or mastic (roofing and foundation cements), anything that resembles or what might be described as a crack.
There are a lot of products that form the exterior shell of the home, and the cracks are usually found where one of these products, such as your windows and doors, butts up against a foreign product, such as a brick or vinyl siding. The products themselves are usually fine, whereby the inherent design of a window, or the manner in which brick or vinyl siding is installed, are by themselves perfectly functional in diverting the elements. However, the challenge to the builder is joining two products such as these to form a watertight seal. Achieving this goal will require the installer using various membranes and flashing products, with the finishing touch to this assembly being a bead of caulking. Over time, it’s the bead of caulking that’s going to shrink and crack, which leaves the homeowner with no other choice but to re-caulk this important first line of defence.
Start by examining the roof (binoculars will help) specifically where the roofs flashings contact either the roof vents, or the side of the home, and make note of where the deficiencies, or problem areas are. Follow the same procedure for all windows and doors.
Although the fall weather provides a comfortable working atmosphere, the challenge at this point will be the falling temperatures. Caulking, paints or stains, and mastics, install better and more easily when the temperatures are at least 5 degrees Celsius. When the mercury drops below this basic user line, you risk the product not sticking properly to the surface it’s being adhered to. When caulking doesn’t stick, it won’t seal, which will mean having to follow this process over again next season.
Basic step number one, remove the paints, caulking, or mastic products from the car and put them somewhere in the house as soon as you get back from the building supply center. Don’t leave them in the garage, or forget them in the trunk of the car overnight. When caulking and mastics are left in temperatures that are close to freezing, they don’t squeeze out of the tube so well. When a cold caulking is moving slowly up the spout, the novice user will become impatient, and inevitably begin to over-squeeze the caulking lever, which usually results in the caulking blowing out the bottom of the tube. A caulking backfire has yet to result in serious injury, but the resulting gooey hands, and loss of what was a perfectly good tube of caulking, will be frustrating.
Next, watch the weather reports, and choose your time accordingly. You’ll want to install the caulking or mastic (roof repairs) while the temperatures will be in the 5 degree Celsius range for two to three hours.
If you’re hoping to do some fall painting or staining, or if the foundation is in need of parging, then you’ll require a 24-hour window of plus temperatures, due to these water based products taking longer to cure. So, if frost is expected overnight, you’ll have to wait until the next warm spell before proceeding.
