Almost every survey turns up something — no property is perfect, and a long list of minor notes is normal. The skill is in telling the routine from the serious. Here are the red flags worth paying real attention to.
Structural movement. Cracks are common and most are harmless, but certain patterns — wide, diagonal, or worsening cracks, doors and windows that won’t sit square, sloping floors — can point to movement or subsidence. These need proper investigation before you proceed.
Damp and its causes. Damp itself is often fixable; the question is what’s causing it. Penetrating damp from a defect, rising damp, or condensation each mean different things. Persistent damp can also be a symptom of bigger issues like failed waterproofing or poor drainage.
Roof problems. The roof is expensive to put right, so signs of a tired or failing roof covering, problems with flashing, or evidence of leaks are worth weighing carefully into your budget.
Timber decay and infestation. Rot and woodworm in structural timbers — roof, floors, joists — can be significant and costly, particularly in older properties.
Dodgy past alterations. Extensions, removed walls or conversions done without proper consents or to a poor standard can cause structural problems and create headaches when you come to sell.
Japanese knotweed. This invasive plant can affect a property’s value and mortgageability and is expensive to deal with. Its presence is always worth taking seriously.
What a red flag actually means
A red flag isn’t necessarily a reason to walk away — it’s a reason to find out more, get costs, and potentially renegotiate. Plenty of properties with serious-sounding findings are perfectly good buys at the right price, once you understand what you’re taking on. That’s exactly what a good survey, and a good conversation about it, gives you.
