What is a Pre-Purchase House Inspection & Report? Why do I need one?
How and why is a Pre-Purchase Inspection conducted by a Member of New Zealand Institute of Building Inspectors
- All houses have the potential to leak depending on their build and the climate conditions
- An initial visual evaluation is done on the property at first glance
- What is the pitch of the roof – How is water diverted from the roof – What is the condition?
- What cladding materials are used – How are they fixed – What is the risk of the cladding system and what condition is the cladding in – What is the height between the cladding and the ground?
- What style of joinery is used –How are the windows flashed and junction joints sealed?
- Are the penetrations –junctions-capillary breaks-Mechanical flashings all water tight?
- We then use the design principles - 4 D’s to access the risk
- D1 – Deflection -Check claddings and flashings for deflection (Aimed to keep water out)
- D2 – Check for drainage paths to the outside if water gets inside the building envelope
- D3 - Drying and diffusion through the walls and ventilation
- D4 – Durable materials for the conditions (How they work)
Deflection is achieved through a number of ways to protect the dwelling from water ingress issues
Once we have established the risks we will check the entire dwelling using the NZS-4306-
2005 Standards - NZIBI
