Burnt Wood Floor Joist - Soldering Pipes

Burned wood floor joist from plumbers soldering copper pipes together isn't going to be that big of a problem, most of the time. In the picture above, there is relatively very little damage to the wood floor joist.

Could this have been prevented? Of course it could, with a little planning by the plumber. The plumber could have cut the pipe about 6 inches shorter and this would have put the plumbing connection that needed to be soldered in between the floor joist.

Another problem that could arise from plumbers soldering near wood floor joist, would be the potential fire hazard from the actual soldering. All plumbers should carry a fire extinguisher, especially when working under conditions like these.

There is something else that I would like to warn homeowners, do-it-yourselfers and even professional plumbers, about soldering near wood framing. There have been plenty of homes lost, simply because a plumber thought that the burned wood floor joist wasn't creating a problem.

Sometimes the embers in the wood floor joist from the soldering can remain for long periods of time, especially if there's a small breeze keeping them hot. The hotter these embers get, the better the chance of them starting a fire.

Things like this happen and you should be prepared for them. It wouldn't be a bad idea to spray some of these areas with water after you're done soldering.
