Domestic FAQs
Domestic — common questions
Do I need a structural engineer?

We provide advice for homeowners, purchasers, architects, contractors, developers and commercial clients across a wide range of project types.
Can you help before I buy a property?
Yes. We regularly undertake pre-purchase structural inspections for prospective purchasers seeking reassurance regarding the condition of a property or concerns raised by surveyors, lenders or insurers.

Commercial — common questions
Do you undertake commercial projects?

What’s the difference between a structural engineer and a surveyor?
Surveyors provide a broad assessment of a property’s overall condition, whereas structural engineers specialise in the performance, stability and integrity of structures. Surveyors will often recommend further investigation by a structural engineer where structural concerns have been identified or where specialist advice is required.
