Understanding Structural Movement in Properties
Structural movement affects approximately 15% of properties in Devon and Cornwall, with repair costs ranging from £5,000 for minor settlement to over £100,000 for severe subsidence. Early identification is crucial for minimizing damage and protecting insurance coverage.
Expert Insight from 30+ Years Structural Experience
Dr. Patricia Williams FRICS: "Most structural movement begins subtly and accelerates over time. The key is distinguishing between normal building settlement and progressive structural failure. Early professional assessment can save tens of thousands in repair costs."
Devon and Cornwall's diverse geology, from granite moorland to clay valleys, creates unique challenges for building foundations. Combined with climate change bringing more extreme weather patterns, understanding structural movement has become essential for all property owners.
Our analysis of over 2,500 structural surveys reveals that properties with monitored movement have 85% lower repair costs than those where problems go undetected until severe damage occurs.
