Attic Storage

JBricks27JBricks27 Member Posts: 678
Will storing my LEGO in my attic over the summer have some unpleasant consequences? I live in northeastern US, and the temperatures probably reach over 90 degrees F up in there. Most sets are still unopened in their boxes but I also have some broken down sets in ziplock bags.

    Short answer, no, there shouldn't be any major consequences of doing this. Long answer, there are many variations or temps, storage methods and storage locations to take into consideration.

    If you do some exploring around here there are other threads that at least mention a lot of this info, perhaps one of the mods can direct you right to one of them.

    Good Luck!

    90 degrees should not effect the bricks, however the hight temperature and the temperature/humidity fluctuation will likely effect the seals on the sets as well as the stickiness of any sticker sheets.

    I stored #6990, which was used a lot and put back in original box, in the rafter space over the garage in Phoenix AZ area. Once during that time it hit 122 deg F at the airport, and the attic was hotter than that. It probably got close to freezing in the winter on occasion. Fifteen (15) years later I got it out gave it a wash and built it. Only effect, some of the 1x4 light grey pieces connecting the tracks were brittle and broke. Monorail still works, light still blinks, stickers are fine. Can't speak to humidity, however, that wasn't an issue. image

    My intuition attic is not a healthy place for bricks! I do store empty boxes up there though, I stack them (smaller into bigger), then wrap them in cling film good few layers, and up they go. I haven't had much experience yet on how they fare over time, but I think they should be fine once protected from humidity.

    I'm in the NE US as well. During a period of construction on our house and for sometime afterward (probably about a year and a half), I had most of my collection in the attic (not finished/insulated), but grew nervous that the fluctuations in temps would affect the pieces in adverse ways. They were all sorted pieces in various plastic small parts organizers or large tubs as well as some sets still in-box. I noticed a VERY slight loss of clutch power on maybe 5% of the pieces when I set about to reconstruct my Winter Village collection about a year ago (which was the impetus for getting them OUT of the attic).

    So, I would say it's probably not the best environment in which to store LEGO.

    I store my boxes in the attic as well. Try to get most of them into my storage bins, but the rest I just put on top of my storage shelve. I do not, nor would recommend you store Lego under such conditions as you so stated.
