What should I do if my chimney isn’t drawing properly?

The first step would be checking all of your damper controls inside/out to see what might be causing this problem.

If that doesn’t work, you might need a professional chimney sweep to come in and fix things up for you instead which is definitely more cost-effective than needing a replacement altogether so keep this step as the last resort since it’s much easier to have someone else do it without worrying about being injured or causing further problems from not knowing what exactly they’re doing either plus those trained professionals know how to deal with scenarios like these too so leave them be unless absolutely necessary!
