Found a leak under my bathroom floor where water was running down the outside of the commode pipes whenever the commode was flushed. Approximately a one foot section of the Support beam under the commode was water soaked and black on both sides of the beam. Turned off the water to the commode and used a fan under the house for several hours to dry the support beam.

The beam seems to be solid and does not appear to be damaged. but is still black Will be getting a plumber to fix the bathoom leak problem.

Any ideas on what caused the bathroom leak? What should I do and who should I call to make sure the support beam is sound, and to prevent mildew/mold? Also, is there any way to remove the black color from the beam that was caused by the water leak?

Help! Thanks.

 

Leak could be from a bad wax ring.

 

spray the mildew with bleach, or you could spend extra and pay for a cute bottle at the hardware store which will be about 90% bleach anyway. Sounds like a wax ring, you will be wanting to check the condition of the wooden subfloor also. Jim

 

Jab the beam, joists and flooring with a screwdriver.
If the wood is solid, it shouldn't penetrate more than 1/4", which will be O.K.
You can do a Search above on repairing bathroom floors, if necessary.
