Protect your home from the winter freeze!

Over the next 10 days the temperature in the area is going to be a high of freezing most days. It is time to hunker down and enjoy the warmth of your home when possible. So fire up those logs and pull out the extra blanket – winter is here. I have written a lot of blogs over the last 14 years about saving energy, making your home more comfortable, and reducing your monthly electric bills. However, 10 days of cold will test any system and all levels of protection. So here are a few home updates to get you through the freezing weather.

Take advantage of the sun and protect against heat loss through windows. Close your insulated curtains on the north side of your house over the next few days and on the south side when you are not getting heat gain from the sun. If you have storm windows make sure they are closed up tight. If you feel air coming through the windows, a temporary fix is to put plastic over the windows. This is not attractive and should not be a long term solution, but it works in a pinch.

Make sure your exterior heating unit is cleared of any snow so it can breathe and make sure the inside filter is clean so it can work efficiently. Most heating units can work 10 degrees and better outside temperature but might struggle on these really cold nights to keep up. If you have gas or electric back up heat your bill could grow quickly. So reduce the set temperature inside when you can and add a blanket to your bed.

Frozen Pipes are a huge problem when temperatures stay below freezing for multiple days in our area. This can happen at an exterior hose connection or just pipes in an outside wall. Read more about what to do to prevent frozen pipes and what to do if you have frozen pipes in this blog “Freezing Pipes: Should I be worried?” Open up the kitchen and bathroom cabinets if they are on an outside wall and keep the door open to those rooms if possible. If you have exposed pipes in your crawl space and it is not insulated (which is should be) then make sure the vents are closed. You need to protect the crawl space in this weather.

Make sure your attic access has insulation over it. In so many houses the attic access insulation was never installed or moved and never put back in place. This is a huge hole in your thermal envelope and should be corrected immediately. Don’t let this one go without checking. If you want to take it an extra step, the attic access is a door and should be weatherstrip sealed to prevent air leakage.

Make sure your attic has the right amount of insulation and is completely insulated. Code minimum has moved to an R60 minimum. I honestly think R30 is economically and functionally all you need – so that is your minimum if you are adding it yourself. However, you want to make sure you don’t block any soffit ventilation if you have a vented attic – this could lead to more problems. If you have ductwork in the attic you really should insulate the entire attic.

Air leakage is a huge concern for comfort on cold days. Leaks around light fixtures, electrical outlets, doors, windows, and even at the top and bottom of walls cause heat loss and energy waste. Make sure your storm door is closed tight and the garage door is down.

Finally, as you start melting away any snow tomorrow, be sure to protect your concrete. Here is a guest post by Phyllis Friesen on the topic.

As they say, this too shall pass – it will be spring soon and there is a whole new list of household tasks that will need attention. I hope you have done the prep needed to be warm this winter but if you have not, make a list so you can get it done before next winter!
