Each night I hear crackling noises in my walls and ceilings? I live in San Diego where the temp gets pretty warm in the day and at night it cools down. Are the crackling noises a result of the wood expanding due to the different temps? The noises only happen in a new edition we built about 10 years ago. Is this something I should be concerned about? It happens both in the walls and in the ceiling.

Happening in only the new addition is good evidence that you are right: that it's just the newer materials still expanding and contracting, "settling in" as it were.

thanks for the note. I'm surprised the noises are still occuring even though the "new" construction was built 10 years ago. Seems like a long time. Thanks!TJ

I'm a bit surprised, too...and was tempted to ask if you've heard these sounds the whole 10 years.

But there are so many variants involved between the weather, the ground and the materials that the new addition was added onto, I realize it very likely is just what we think.

i put in the insulation spacers in my roof rafters (the styrafoam ones). i still haven't insulated, but as the roof heats up it starts to sound like rice krispies. i'm hoping that will be muffled by the insulation and drywall.

just a thought..

tjpapa

sounds exactly like rice krispies. As for insulating, the people who built the addition did not cut out an entry way to the attick in the ceiling. Don't know why but looks like I'll have to cut one out myself to add insulation, if they haven't already but how would I know since I can't get up there. :-)

RickJ

It would be worth knowing...just don't cut into the ceiling until you know what size and style of access panel/cover/door you will use.

Decide that first, then cut the appropriate sized hole.

good idea, thank you.
