Wood Rot

Hello everyone from the Philippines!We have a problem with our wood flooring. I wasnt here when the house was built but according to my parents narra wood was used for the flooring.I tried google image to see if there was something similar to what is happening to our wood but i havent found anything similar to it.Can anyone identify was is happening to the wood and what could be the cause? I guess some parts can still be restored but some are just too rotted beyond repair.Any help or info will be appreciated. Thanks everyone!

I am not an expert remotely in this issue, but I suspect (and may well be incorrect) that what is happening is some form of wood rot. That is a fungal attack, due in part perhaps to the atmospheric humidity conditions in your part of the world.

I found a reference Fungal Decay | Australian Building Inspection Services which may help explain, what perhaps is occurring to your flooring. Again perhaps it too, or similar articles may give advice as to how to treat and repair your floors.

I'd vote for dry rot (called dry rot as it doesn't need water contact, just a humid atmosphere).

Rip it all out, check the bearers and joists underneath and replace as required, and while you are underfloor, add sufficient ventilation to (hopefully) stop it happening again. Check to see what timber treatment options are available to you, such as boric acid or copper napthenate (sp??) to discourage re-occurrence.

Thank you, at least we're getting somewhere.
We really need to move fast because the rots are developing in different parts of the house.

I'm not sure what the building regulations (or the enforcement thereof) are like in the Phillipines, but here, any subfloor areas need to meet minimum ventilation requirements. Youi'll find them here:
