Undersink water damage

[momdidit]

I have water damage under my kitchen sink from a slow leak and I need to repair the wood damage myself. The house was built in the 1970s and is not like the module construction you find in new houses today. Has anybody got tips on how to fix this or a source book I can get from the library? Thanks

only advice i can give is you must first find out how much water damage has been done by taking out a small section of the bottom of the sink base on the inside under sink.....but if their is floor damage under the sink base you will need to take out the complete unit and repair floor as needed.
''''''''''''''''''''''''''''with the limited info you posted i am only speculating that the base is rotted from the water damage....only then should you consider cutting out a small section of the floor base of cabinet to inspect the actall floor under and that is only if you cannot view this from a basement or craw space......;;'''''''''''''''''''''''''''''''''''

First of all is the water leak fixed?
Upon removing the cabinet bottom, what color is the floor? Gray or green or black? If it is osb does the wood look like it expanded? Does it readily give way under pressure - press on it with your thumb and see.
If it feels "punky" then you'll probably have to replace it. If it seems solid then try an application of "PENETROL" sealant. This is a solvent based oil which is supposed to rejuvinate dry rotted wood.

If the water leak is now repaired and the damaged is localized to be mainly inside the sink base cabinet then repair the cabinet base (by adding a 1/4" or 1/2" shelf). As long as the leak is fixed and the damage is not structual then removing the cabinet to repair OSB or other sub flooring seams a little drastic considering the fact that it is under the cabinet.

The very first thing you need to do is to fix the leak, then tackle the rotted area.

If the entire bottom is water damage, cut it out by cutting a straight line down the middle, with a skill saw, or a jig saw...http://www.alhomerepairsyourself.com
