We just had a chimney sweep come to clean our chimney. Before they even did anything they wanted me to go up on the roof and "look". They said I would see that my chimney needed relining. When I made it clear I was not interested in them doing an immediate repair they just left without even cleaning the chimney. There are no signs of dark soot from the chimney or anything else I can see. What signs should I be looking for? Relining is expensive and I do not want to contract for repairs I do not need.

Are you referring to a chimney for a fireplace or a heating system? The signs would be loose and crumbling clay liner on the interior of the chimney. There wouldn't necessarily be visible clues from the exterior.

Did the sweep tell you he was sure the chimney would need relining even BEFORE looking at it? Did he see any evidence from the ground that the claimed to be a problem?

I am not sure if he actually looked. He acted as though he had: he said he wanted me to get up there and look. Since I would not have the faintest idea what I was lookijg for, I said no. I have thought I might get someone else to assess the situation, an expert with no monetary incentive to arrive at a particular conclusion--assuming I can find someone who fits the bill. Any suggestions on that score would be welcome.

Wow, do your mechanics there tell you to look into your exhaust pipes also?
Would you have any idea what you were looking at?, probably not, which is what these scam artists rely on.
Alfred hit a few points, fireplace or furnace? Clay or metal?
Newer furnaces produce exhaust that is cooler,which has a tendency to give up the moisture in it before exiting the house.This moisture is acidic(byproduct of combustion) and will eat at the morter on clay stacks.This is a problem in chimineys on the outside of houses,generaly not a stack that runs in the middle of the house(insullated from cold air).
Fireplace, do you have "sandy" material directly below the chiminey?
I would call a trusted/recommemded heating and air company,possibly two if the work needed is extensive, to inspect the problem
