Property inspections & testing you can trust.

Your peace of mind is our priority.

Buying or selling a property is one of the most significant financial decisions you’ll make. Residential, commercial, or industrial having a clear understanding of a property’s condition is essential for peace of mind. A professional inspection ensures there are no hidden surprises, helps you make informed decisions, and can streamline the sales process by reducing uncertainty for all parties involved.

At BT Advisory Ltd, our experienced Master Inspector conducts thorough non-invasive inspections of both the exterior and interior of the property, in accordance with NZS 4306:2005 guidelines. Each inspection covers all key structural and maintenance aspects of the building, identifying potential risks, defects, or areas requiring attention.

Following the inspection, you will receive a comprehensive written report, complete with clear reference photos and easy-to-understand recommendations. This report gives purchasers the confidence to proceed with their purchase and provides vendors with an independent document to support the sale, often reducing purchaser due diligence time.

Whether you are a first-home buyer, a seasoned investor, or preparing your property for market, our pre-purchase and pre-sale inspections give you the knowledge and assurance you need to move forward with confidence.
