I was understand that it is only a ten minute job but here is the scenario
you sweep you're chimney and unexpectedly while using it you haveba chimney fire.
you call the insurers and they send out the assessor who look at it and then asks to see the certificate from when bitbwas last swept. if you can't provide ba current one they say they claim is void asbit has not been swept tonan approved standard
thats the thing will insurer's they take you're cash but when you want it back if the paper work is not right they say no
