Insulation Is For All Seasons

April 30, 2014

It's a beautiful Friday afternoon, unfortunately for me, a fairly uneventful one as well. I'm thinking of calling it a day and heading home early for the weekend; besides I'm just getting in the way of all the contractors! We're expanding our head office you see and are in the midst of a major renovation project; the building is infested with contractors, and they're crawling all over the place.

All this renovation work has got me thinking (this happens every now and then); a lot of you will soon kick-off your spring/summer home renovation projects. Some of you are probably thinking of renovating the deck/patio, adding a new pool or backyard Jacuzzi and some of you are probably even drooling over the thought of brand new granite kitchen countertops!

The last thing on your mind right now is an insulation retrofit, especially after you consider the abnormally mild winter and this beautiful spring weather we're having. Besides... how important can insulation be anyways?

Actually, an insulation retrofit is probably the single most important home renovation investment you can make and it yields one of the highest return on investments when compared to other home renovation projects! Yikes, I know kind of salesman-ish but what else would you expect me to say? In all seriousness consider the following facts:

If you haven't heard already, the provincial government has approved a 12% rate hike to hydro bills which will take effect this May. Just in time to cash-in on the normal summer hydro consumption spike (worth noting: Environment Canada predicts temperatures this summer, will be above average). Add in the HST and the new green' tax, and your hydro bill could jump by as much as $300 by the end of the year!

Remember insulating, not only helps to keep warm air in during the winter, it also helps to keep warm air out during the summer. A professionally completed insulation retrofit will help decrease your energy consumption by nearly 30 percent. The air conditioner won't have to run at full blast, which will help decrease your energy consumption and prolong the life of you're a/c unit.

If you read the recent post, then you know that you could save nearly $360 per year with a professionally completed insulation retrofit. It seems like a no-brainer to me; you decide: an extra $300/year in hydro bills? Or savings of $360/year?

Just a little something to mull about over the weekend. Have a good one!
