Can anyone give me an estimate on how much it would cost to enclose a cement slab patio with a full roof over head. The room would be 12X22. I would like about six windows and a sliding door. I live in Iowa, if that matters. I would like it insulated but I am not planning on doing anything with heat or air ducts. There is already electricity.

My patio door is not sealing properly anymore. It is about 12 years old. The door is square but I believe the house has moved some which is causing gaps. What are my options for getting this fixed?

A) Should I replace the whole assy, door and jam included?
B) Should I replace the jam only?
C) Is there a way to take the molding off the jam and re-adjust the door assembly so that it is square again?

Thanks.
This is not a sliding door.

Just got a new patio sliding door and I noticed that there is gap which can allow insects to creep in. The other door is okay but the one where the screen is located is not tight. I could have sworn my older patio door (1980) was tight to the gliding track. I purchased a Perma-Shield Gliding door by Andersen. What can I use besides a cotton drafter to prevent insects from getting in?

My patio door has been shot with a b-b gun, spider webbing the outside portion of the 2 pane glass. I need to replace just the sliding portion of the door unit, and I am not totally sure how to remove the sliding door and replace with new one. Where is it possible to buy just the sliding door and not the whole unit? Estimate?
