A client recently contacted us after noticing signs of timber decay within their property and wanted our opinion on what it may be.
A photograph of the top of the radiator was run through AI to see what it would identify, and it said that this was “rust and surface corrosion on a central heating radiator, not dry rot spores.”
A leaking valve can certainly cause rust and staining. However, the material we found was not simply surface rust, and AI did not consider the full picture of the conditions on site. During our inspection, we found significant cuboidal cracking to the affected skirting boards, along with fungal strands across the rear of the skirting.
This is where AI has its limitations. A photograph can provide useful information and help point towards possible causes, but it cannot replace an onsite inspection and professional assessment of the wider evidence. The material on the radiator could be wiped away with a finger. That’s a physical observation that simply cannot be made from a photograph alone.
AI can certainly have its uses, but when something as important as identifying the cause of timber decay is involved, it raises an important question, if an AI assessment gets it wrong, who is responsible for the consequences?
If you're concerned about damp, mould or timber decay, don't leave it to guesswork. Get an independent professional opinion. That’s what we’re here for. We can help you understand what is happening and what to do next.
