I recently had a SS flex liner installed inside my existing chimney clay liner, there wasn't enough room to insulated the SS liner. It hasn't been really cold and the draft seems fine. The chimney is on the outside of the house. They also extended the chimney hight to get it up to code. Will I be alright, or did I get ripped off because it cost quite a lot of money to get this done.

It’s a little hard to say if you got ripped off, or will you be fine with the info given.

Typically you would want an insulated liner. It’s very hard to verify that a chimney has the required clearance to combustibles like house framing. Insulating the liner is a way around this step of verification. Often they need to break out the clay liner to make room for the insulation.

Insulation also helps keep creosote formation down as the liner stays warmer and water with creosote forming soot particles is less likely to condense onto them.

Labor and stoves are expensive, the cost goes up quickly.

Better if insulated but the real importance of the insulation is protection from chimney fire. Regularly sweep/inspect that chimney and you drastically decrease that risk.

Yeah they should have removed the old clay liner for insulation. They did clean the old clay liner before installation. I should have done more research, hindsight always 20/20. Should I call them to come back and do this correctly?

The chimney was in use until this past spring without issue, if that's any help.

I suppose I will be alright for now? maybe next year buy a pre-insulated 6" liner that would fit? Will I have any issues with heating up any residual creosote?

Sorry for all the questions, im just concerned. I intend on cleaning the chimney every year at minimum.

Good that flue was cleaned before install of current liner.
Regarding residual creosote- there is hopefully only minimal creosote that was missed by the cleaning this time around, so that temp from liner doesn’t ignite a fire. Cleaning near the old damper can be easily missed or done incompletely and perhaps targeted for inspection/cleaning if you re-install insulated liner in future. If so, I’d advocate they remove the old metal damper to allow access to tight spots in order to make sure clean.
 
No worries, I should have mentioned that in the first place. I just feel stupid for not doing my homework, I was in too much of a hurry to get my wood heat back before the cold hits, like it has today.
Grew up in Cincy. Are you in the city proper or the burbs? I grew up West of the city just a bit. I miss my hometown! What sort of temps are you looking at? We're at the the mid fifties with a cool off on Tuesday morning to the high 20's.

I grew up right down the street from Price Hill Chili, so if you're a west side or you're familiar with that.

I now live about five miles west of there, definitely out in the suburbs with six acres of land. In total I'm about 10 miles from downtown Cincinnati.
