The last doors I had dipped cost me £15 each, I had 6 done and they collected and delivered them back.
Tips?
Try to get someone to recommend a good stripper, they can ruin the door if they are not careful.
Have them done in the summer
if we have one, as they will probably come back wet, and you will need somewhere to stand them out to dry.
Expect to do quite a bit of sanding, not all the finish will be gone and the stripping process will raise the grain.
Well worth the hassle though.
