It is a good idea to check all windows and doors to be sure they are closed. Cars should either be put into garages, or moved as far as possible away from work area. Rugs behind doors should be pulled back a little in the event the threshold is not completely tight. If there are any areas of concern (areas that have leaked previously) this should be brought to the attention of the Franklin Cleaning Inc office, or at the least, the foreman on the job.
