Windows, doors, shingles and siding - Favourite contractos in calgary?
 

As some of you know, I'm living in a house that was built around the time of WWII, and it's in need of some renovations. Just wondering if anyone on here has contractors that they have worked with recently and would reccomend.
Project that are under consideration, but possibly not all this year, are:
Shingles
Gutters
Siding (something that will increase the insulation value preferably)
Windows (ours don't seal well at all)
Doors (wind whistles in all winter, brrrrr!)

I'm looking for a way to cut down on the number of phone calls I have to make. There must be fourty window contractors in the yellow pages!
