We would like the improve the exterior of our vinyl-sided Colonial home by installing some shutters and window headers. Since our vinyl siding is pretty old and the weather is getting cooler, I am concerned about potential damage to my siding during installation. The siding contractor that will be installing them does not think the age of the siding or the temperature will be an issue as long as it is above freezing when the work is done. I wanted to get some more opinions on this issue before we proceed since I do not want to do anything that would potentially damage my siding. Temperature this time of year is generally in the 50s during the day and mid 30s at night. Would it be okay to install them in this type or weather or should we postpone this project until the weather is warmer?
