I am currently renting the house I am buying. The owner agreed to get the chimney swept (used to be oil boiler, changed to gas last year but soot coming through vent today. Ll arranged a chimney sweep who cane today. I was not prepared for the left over mess. The flu is in the kitchen diner but I thought he would clean up but I have washed the floors 3 times, its all Iver the doors, downstairs toilet, hallways etc where he has walked through and touched things. It's impossible to clean no matter how many times I do it. Is this normal? Are they meant to clean the area after so it looks relatively the same? Should it be all over the house like this? Any tips for getting it clean. I have hoovered, mopped twice and scrubbed on my hands and knees and it still isn't completly clean.
