When buying a property, most buyers will instruct a survey for their own peace of mind and to satisfy the requirements of a mortgage lender.
Your structural survey relates specifically to the integrity of your walls, roof supports, foundations, drains and other major structural components that would significantly affect the durability and safety of your property eg retaining walls. These are major issues caused by either a lack of care, poor workmanship and could potentially cost thousands of pounds to put right. In the worst case these issues could lead to huge amounts of damage to your property.
A Structural Engineer can visit your property either during the due diligence phase for your own peace-of-mind to determine whether there are any structural issues with the property. Common symptoms of structural issues are:
Cracks in walls either inside or outside
Doors that are sticking
Windows that have buckled and no-longer open
Obvious bends or skews of door and window frames
