I was REALLY hoping someone with more experience would answer this post. But (as those around here know), lack of experience hasn't stopped me from responding yet! :)

Actually I did try un-warping a door once, but it was NOT a heavy exterior door. And this was over 20 years ago--so my recollection might be, well, faulty.

I found that, using a cable with turnbuckles and putting something under the cable (like a 2x4), I was able to take SOME of the warp out.

I found that it was "easier said than done" trying to figure which way to attempt to unwarp it! Also, the warp might not be all that uniform. In my memory, it all was kind of hit-or-miss but I had some success.

And that was, again, NOT an exterior door. I think you're gonna have your hands full. I generally think that most exterior door work needs a professional.

Also, why did it warp in the first place--and what is to prevent it next time? You might consider putting up a storm door.

I did try some searches and found some links--hopefully they'll be more helpful than my post :) You might try some internet searches of your own, too....good luck!

Oh, and...I forgot to mention! Whatever method you use will take TIME! Don't try and take out all the warp at once!

Again, good luck!
