  • Good and bad techniques in insulating basement walls.

    The national building code requires a minimum level of insulation in a basement that reaches about two feet below the outside grade level. The objective is to make this storage space a heatable space. Hence some materials and techniques have developed that satisfy this minimum code requirement th...
  • Vapour barriers in basements

    One of our viewers is about to insulate his basement and he has been told that he should not run the vapour barrier all the way to the floor. Fact or fiction? You should run the vapour barrier wherever there is insulation to keep the moisture on the warm side of the wall. And in a basement insta...
  • BASEMENT: INTERIOR OR EXTERIOR INSULATION?

    It is always better to insulate on the outside of basements and crawl spaces, but usually more expensive and more trouble. Brick or field stone foundations must not be insulated on the inside for much more than one foot below ground level. The poor quality of the mortar in these foundations dete...
  • Full height basement insulation? An animation explaining why the answer is YES.

    An animation on a CD that I produced with the Reader's Digest several years ago showed clearly why you should insulate the entire wall all the way down to the floor. No, you won't freeze anything outside, as the important footings are below the frost depth anyway and there is always some heat los...
  • How do you insulate a basement wall that has a pony wall?

    Ron from Penticton, B.C. has a "stepped" foundation with a pony wall from the concrete to the ceiling above. This upper portion is insulated but not the concrete. He wants to insulate it all. He asks: "Does he have to remove the existing drywall, and does the vapour barrier need to extend over th...
  • How far down should you insulate on a basement wall?

    As you can see in the first graphic, the soil helps to insulate a basement so there is more heat lost on the top of the basement than on the bottom. That is why the National Building Code requires a minimum level of insulation in a basement that reaches from the floor boards above your head, down...
  • Tracing the source of nasty plumbing odours

    Evert from Brownsburg, Quebec has the problem of a sewer odour in his bathroom but isn't sure where it is coming from and whether or not he needs to change his toilet. It can in fact be difficult to localize the source of sewage odours and hence which fixture or drain is guilty.  One technique ...
  • How to clean aluminium and vinyl siding.

    A viewer caught our TV cameras in a renovation centre and asked about cleaning aluminum siding. An interesting fact about siding is that white aluminum siding and to some extent white vinyl siding both tend to "chalk". If you run your hand over it, you get a bit of a chalk like deposit on your h...
  • BBS: Raised Heel Trusses

      How do you get enough space above the wall and below the roof for both massive insulation and ventilation? One way in new construction, or even in the rebuilding of a roof, is what we call a Raised Heel Truss. This design forces the overhang of the house further out from the house, but does gi...
  • Truss Up-Lift -- that changing crack between the wall and the ceiling

      In all too many new houses, there is a seasonal problem where in the winter the ceiling actually lifts itself right off the wall in the centre of the house, and then settles down after the heating season.  Even in some older houses this goes on every year.  What causes this crack? Avoiding...
