We also needed two fire bricks changing .
They cleaned and dismantled the stove. Went on the roof with a big weight that was covered in bristles and lowered it down the flu. after about 5 mins of going back and forth, he came back down and cleaned again.
finally fitting it all back together and doing a test fire to show us it wasn't smoking any more.
Total time spent, about 45 mins and cost around 250 tl. The new firebricks were included and cost around 75 tl each but he only charged for one.
Professional and tidy.
