Subsidence: why you should always book a Building Survey
This wonderful house you’ve just bought was partly based on the beautiful ambiance provided by the surrounding oak trees. You’ve become a little worried though, because you’ve recently spotted a little crack in the rear wall – is that just settlement or, please let’s hope not, a sign of subsidence?
What causes subsidence?
Tree roots are the main culprit and Which? has estimated that they are the root of the problem in 70% of cases. When they are combined with shallow foundations, clay subsoil and dry weather, you can have a toxic combination.
A crack doesn’t always mean there is subsidence and could just be settlement in the property. However the clear advice is, if you’re thinking of buying a property and you view a crack, you should get a RICS Building Survey to establish whether your surveyor suspects this to be subsidence or simply a little bit of movement.
Can the problem be fixed?
The good news is that subsidence can generally be fixed and only around 10% of subsidence affected properties require underpinning. The cost of underpinning ranges between £5,000 and £80,000 depending on the condition.
There are alternatives to underpinning such as Jet Grouting; this fills void areas or can even inject chemical to turn the soil into solid aggregate. There are also supportive systems using piers, piles and jacks but all of this will depend on the properties location and the severity of the subsidence.
