Just tell the customer that there is no acceptable way to splice or extend data cables. So moving an IT closet shouldn't be taken lightly. Some damn customers think like women rearranging furniture. The only real way is to rerun the drops that can't be pulled back to reach the new location.

I also get this from time to time from customers who move into a new space and want to re-use the old crap that was left there from the previous tenants. I just tell them that I have to run new runs as well as charge them to pull out the old stuff that the landlord should have made the old tenants do.
