A number of residents have received calls or visits from the Lysco Chimney Maintenance and Repair company saying that they are in the area and asking if homeowners would like their chimneys cleaned. The Lincoln Police warn that this company has a long list of complaints against them for being very aggressive on the telephone and then, if the homeowner agrees to have them clean the chimney, wanting to perform other costly repairs that do not need to be done and are not done properly. They are using a white van with the words Lysco on it. If you have concerns or have had Lysco come to your home, please call Officer Surette at (781) 259-8113.
