Hi, just finished sheetrocking, drop ceiling, electrical and plumbing, all the trim work is next... How high off basement cement floor should I install baseboard moulding? I plan on either putting carpet, or vinyl tile over floor after moulding and painting is done.. Alos, should I paint the walls, then install moulding or install moulding and then paint walls and moulding? Thanx for an help you can give me...

my calgary, alberta home is 10 years old and we have started to build out our basement. we decided to pull down the insulation to check all walls b4 we began. behind the insulation was a vapor barrier from the basement floor up to about 2 feet from the ceiling. behind the vapour barrier was moisture on the walls. Where there wasnt a vapor barrier it was dry. Is this normal? Where there was moisture we applied some type of sealant - crystal coating over the walls. It called for a few applications and to dry between applications. Was this a good idea ? We also found some hairline cracks in the walls and 2 very long ones starting at the bottom edge of the basement window and leading down to the floor. Are hairline cracks normal or is that a sign that its time to move? We drilled the cracks a little bigger and then cemented them back up. Was this a good idea? The basement is 800 sq ft. how many heating vents and cold air returns do you recommend? What is the best type of carpeting to lay on a basement foor and is a underlay recommended or will that hold the moisture in and eventually mold?
