so i have had my hampton insert for a year and a half now and am thinking about how i am going to clean the chimney...it has a 6 inch ss insert all the way up....instead of paying somebody a bunch of money to clean it can i just go buy some brushes and rods and do it myself? it doesn't seem like rocket science....on that note, my annual inspection should include what? fire bricks inspection? where does one get chimney cleaning tools and is there anything more to it than starting from the top and brushing all the way down to the firebox?
