In the next week or so I will be installing a new Therma Tru fiberglass door. The enrty has a single concrete step into the house on to a concrete four season front porch. Everything is stable and has not moved in the last 40 years. When the original door was installed, some 40 to 80 years ago, the threshold was 1/2" out of level. It also dips down almost an inch on the porch side. I am wanting to bring this up to level. My first thought is to use self leveling cement that I have used before when I put in a heated tile floor. Not sure how this would hold up, warm on one side and outside elements on the other. Any other ideas? Thanks, Mark.

I actually addressed this not too long ago and got some great feed back as to the cause.........since then I have come across some rather confusion information and thought I would run this buy the forum. First I have read where contacting Anderson is almost impossible. I have the standard flip up 28x13 basement casement windows, they face the south and sometimes I suspect when the sun in the winter his them, some condensation will form.....not allot but something that concerns me. My original thought was to install a storm on the outside, something that would take the wind chill and temper it abit; actually wondered if Anderson made an insert with glass like the screen. Some see to think this is a waste of money, the air gap formed between the window and the screen will do very little if anything. Any thoughts? Then I read someplace where the real solution is a quilt cover, one that can be made as a curtain or actually affixed on the window frame itself with velcro...........this will keep the warmer temp in the basement off the outside glass and eliminate the condensation. This was new to me; any thoughts as whether this is the correct way to handle condensation? Basement is not heated, temp in the finished basement in the winter probably drops to maybe 57 during Dec-Feb. Would love some feed back, I suspect some have had similar issues and have found resolved either with storms or an inside solution.
