Will No-Rot fix badly rotted timber?
No, and neither will any other preservative. Preservatives kill the fungus and stop decay spreading; they don't restore strength. Badly decayed timber has to be cut out and replaced, and if it's load-bearing that's a licensed tradesperson's call. They work best as a preventative and an early intervention — fungus growing in bathroom architraves, for instance.
Will it stop termites?
No-Rot controls termite and fungal damage in the timber it treats. But it's a localised treatment: it protects the timber it's applied to, not the colony or the wider structure. For an active infestation, contact a licensed pest control specialist.
I have mushrooms growing out of my bathroom timber, what can I do?
Mushrooms mean the fungus is well established and the timber has been wet for a while. Sort the water out first — ventilation, a failed seal, whatever is keeping it damp — or it comes back. Then treat the timber: NØ-ROT Gel brushed on where you can reach, or NØ-ROT Inject into architraves and joinery where a brush won't. Both help control the decay in the timber they're applied to. If the timber has gone soft, it needs cutting out.
Do I really need to use a timber preserver?
Timber costs more every year and good structural stock is harder to come by. Replacing a rotted bearer is the timber, the labour, and pulling apart whatever sits on top of it. Treating it while it's sound is a fraction of that — and it's the part of the job you still control. Protect it before you have to replace it.
