Fire Barrier


My husband and I are installing a new bath tub and surrounding tile. Last night we ripped out all the old tile and noticed something pretty disturbing. The pipes that come up from the basement run up along some studs. On the studs the wood has turned black. It looks like the hot water in the pipes was so hot that is actually started burning the wood! Before we put up new walls and tile we want to put in some sort of fire/heat barrier between the pipes and wood. Any suggestions on what we should use?

Thanks a lot,
Kris

hot water pipes could not have gotten hot enough to burn the wood. If this is actually a burned area, is there a soldered joint close by? Often a plumber will not use the proper shielding blanket when soldering and burn the surrounding wood.


the other thought just to be sure: it's not mold, right?

the one other though is there was a fire in the house at one time. Is the area contained to just near the pipes?

Thanks for the quick replies.

The house is from 1891, as far as we know there was no fire, but obviously with a house that old you never know for sure.

The burned wood area is contained. It is just behind the pipes. We have not seen any other fire damage in the house.

We are sure it is not mold, looks exactly like charred wood. The plumber error sounds very plausible, since we found out that most of the bathtub area was done on the cheap. (The old tile was laid on top of regular drywall, so I would not be surprised if they cut corners when installing the pipes).

SCUBA_DAVE...the pipes are for heating. It's two pipes (I assume one hot, one cold) that come directly from the basement and meet where the faucet to the bathtub attaches. Then there is another pipe that goes up from the meeting spot up to the shower head.

Now that I think about it, the wood is black behind both pipes. Assuming one is hot and one is cold, it does not make sense that the wood would be charred behind a pipe carrying cold water. So the plumber error that NAP mentioned makes even more sense.

it is very common to find such charring. While the plumbers seem to think nothing of it, I see it as a lack of concern for quality and appearance of a job. Generally it causes no harm.

Also common in older homes for slightly charred wood to be re-used

I'd say that's from soldering the pipes

Thank you for the picture, it helps keep my post numbers down by not guessing repeatedly........ lol.

p.s.- smack the drywall screws with a hammer instead of unscrewing them.

Be safe, Gary

Probably too late but that metal strap on the left in the picture should be replaced with copper or other. It will react with the copper over time and could cause a failure.
