        Black discoloration from studs behind drywall Sign In/Join 
        posted
        I have two attic bedrooms that was re-done in 1996 (new sheetrock, insulation etc...) For the last year in the larger of the two bedrooms there are black lines on the ceiling and walls that match the stud locations lengths and widths. The area on the drywall between the lines are clear and not discolored. The smaller bedroom does not show any of this. I have never seen or heard of anything like this. Has anyone ever seen this before and can offer suggestions as to what this is and how to fix it?

        It is called "ghosting". Do you burn candles in these rooms? Is there a combustion device in this area, like a gas furnace or a fireplace?

        Here is an article on the subject. Link is a pdf.

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        Thank you for your reply. Your reply seems to have hit the nail on the head so to speak. She does burn candles. I also followed your link and the condition is covered in it. There is another issue. In the same room there is an 8 bulb track lighting fixture with 50 watt bulbs that came with the fixture. There is what may be ghosting circles above each light bulb. These bulbs are also very hot. Could the problem be one and the same except for the heat emanating from the bulbs?

        a sticker should be affixed to the part of the light fixture where you screw in the bulb,,,it will tell you the max bulb size to use
        i have a shop light above my reloading bench, it has a plastic shade on it.
        i put a 100 watt bulb in the lamp and it burnt the shade....

        Get some LED bulbs for replacements (they continue to come down in price and sometimes very reasonable off ebay). Or spiral fluorescent bulbs if nothing else. Either would would save both energy cost and heat. BTW, the wax, battery candles are what we have switched to (no soot or fire danger).
