We're finishing a basement as part of an addition, and our contractor initially said he would insulate the basement. We have had a slight moisture problem on the bottom 3 courses of block, but we solved it between a dehumidifier and 3 coats of Drylok. Now, the contractor is saying we don't have to insulate because the basement stays at a constant 55 degrees year-round, and if we insulate, we'll roast in the winter (we have baseboard heaters going in). I've also learned that there are mold/mildew concerns when insulating walls that have shown to be damp from time to time. So, the QUESTION: How do you know when it's best to insulate or not insulate your basement, and given the set of circumstances I laid out, would you do it if it was your house? THANKS FOR ANY HELP YOU CAN GIVE ME!!!

"Now, the contractor is saying we don't have to insulate because the basement stays at a constant 55 degrees year-round, and if we insulate,"

Long gone are the days when you just opened the window if it got too hot in the winter and let the furnacne run full tilt.

If you insulate you won't roast, the thermostat will shut them off.


Now I am concerned about what was the cause of your moisture problems.

The RIGHT way to cure that is to keep water way in the first place and that is down from the outside.

Look at this for details of insulating a basement.

If you look around you will find lots of other usefull information.
