Stainless steel liner in furnace flu?

Hi,
I recently purchased a house that was built in 1958. There are two flus, one for the fireplace and one for the hot water furnace in the basement. I have had four different estimates/opinions on the condition of the furnace flu and whether I need to shell out $3,000 for a stainless steel liner. Two chimney sweeps have said there is significant deterioration and I need to have this done or else I risk a fire or CO2 emissions in my house. Two others have said it is fine as is, and have confirmed there are no terra cotta pieces or debris at the bottom of the furnace, and also that the draft is adequate to expel all gases and emmissions. I have attached pictures I took yesterday after climbing on the roof and looking down the furnace. Note that the first joint in the picture is about three to five feet below the furnace top and is not adjacent or contacted to the house. I'd like opinions as to whether this work needs to be done and if so if there is anything I can do myself to save the money?

Thanks.

Dan

It looks OK to me except that top tile, and the gap that is there. The tiles should sit ontop of each other and or have a mortar joint.

Is that top tile joint above the roof line? Are the other joints the same? ( I cant tell from the pics.) I guess the flue gas can get sucked back into the airspace between the tile and outside masonary.

Another thing a liner installed with labor in PA should not be more then $800 to $1000. Thats NJ prices anyway and PA should be cheaper.

It would seem someone is trying to make money off you.

Thanks Mike for the reply.

The top tile joint is above the roof line. The other joints do not appear to be in much better shape than the top joint.

That being the case is your opinion to go with the liner or do you think it is ok since it is above the roof line?

Well are all the other joints the same as the top one with that big gap?

If so it would be my opinion that it was not installed correctly and would pose a health and saftey hazard.

I would want a chimney line.

Wait for others to chime in. But this is how it should be all the way down.

I think I paid like $1300 for my chimney liner. Height does play a roll. You can always DIY.
