Iím getting married next month. My parents wish to arrange the function at our hometown. My fatherís family is very big consisting of more than 100 members . They are settled in different parts of the world and couldnít always find much time for a family reunion and we havenít met for years so my marriage will be an occasion for us to meet together after long years so we are planning to arrange the function at our ancestral home. Itís a very old building and was unoccupied for years so the property should be cleaned before the function. We have consulted some local workers for getting the work done. All other works except the window cleaning is done . The windows are too old and the glass panes are completely covered with dust. The efforts put on cleaning them was worthless. Workers suggested me to replace the windows but I donít wish to ruin the beauty of the building by replacing them. Iím sure I couldnít find such beautiful ones so Iím planning to consult a professional agency for getting the windows cleaned . My friend Cathy provided me with a website of a window cleaning agency ( http://www.rbcclean.com ) but Iíve no previous experience with them so I need advises from experienced people here. Please help me to solve this issue.
