10 Common Defects We Regularly Find During New Build Inspections
Building a new home is an exciting milestone, but many homeowners are surprised to learn that brand-new homes can still contain defects. Construction involves multiple trades working across different stages, and issues can occur despite quality control processes.
At Inspecta Holmes, we carry out independent new build inspections throughout Wollongong, the Illawarra, Macarthur and South West Sydney. Our inspections regularly identify defects that may otherwise go unnoticed until after handover.
Here are 10 common defects we regularly find during new build inspections.
1. Defective Waterproofing
Waterproofing defects are among the most significant issues identified during construction and can be difficult and costly to rectify once tiling has been completed.
Common defects include:
- Tears or damage to waterproof membranes
- Inadequate coverage around floor wastes
- Poor detailing around shower niches and penetrations
- Membranes not extending to the required heights
If left unresolved, waterproofing defects can lead to water ingress, mould growth and ongoing maintenance issues.
2. Cracked or Damaged Roof Tiles
Roof defects are commonly identified before handover and can allow water to enter the roof space if not addressed.
Common issues include:
- Cracked roof tiles
- Loose ridge capping
- Missing pointing
- Poorly secured roof components
Early identification can help prevent future leaks and water damage.
3. Poor Paint Preparation and Finish
Painting defects are among the most common items identified during PCI (Practical Completion Inspection) stages.
Typical defects include:
- Paint runs
- Visible patching
- Poorly sanded surfaces
- Inconsistent paint coverage
- Marks and scratches to walls and ceilings
A quality finish relies heavily on proper preparation before paint is applied.
4. Inadequate Sealing and Caulking
Sealants play an important role in preventing water ingress and achieving a professional finish.
Common issues include:
- Missing sealant
- Gaps around fixtures and fittings
- Poorly finished silicone
- Inconsistent application
While often considered minor defects, inadequate sealing can impact both appearance and functionality.
5. Brickwork and Masonry Defects
Brickwork should be completed to an acceptable standard of workmanship and presentation.
Common defects include:
- Mortar smears
- Uneven mortar joints
- Chipped bricks
- Poor alignment
- Inadequate cleaning of completed brickwork
These issues can affect both the appearance and durability of the home.
6. Tiling Defects
Tiling defects are regularly observed during pre-handover inspections.
Examples include:
- Tile lipping
- Cracked tiles
- Hollow sounding (drummy) tiles
- Poor grout finishes
- Missing grout
Rectification is generally easier before the property is occupied and furniture is moved in.
7. Incomplete or Defective Roof Plumbing
Roof plumbing plays a critical role in directing water away from the home.
Common defects include:
- Disconnected downpipes
- Inadequate falls to gutters
- Leaking gutter joints
- Damaged flashings
Poor roof drainage can result in water damage, staining and long-term maintenance concerns.
8. Frame and Structural Defects
Some defects can only be identified during frame inspections before plasterboard is installed and conceals the structure.
Examples include:
- Damaged framing members
- Inadequate fixings
- Incorrect bracing
- Non-compliant framing details
Identifying these issues early allows defects to be rectified before they become hidden.
9. External Drainage and Site Issues
The way water moves around a property is just as important as the structure itself.
Common concerns include:
- Inadequate site falls
- Water pooling against the home
- Poorly graded landscaping
- Drainage not directing water away from the dwelling
Poor drainage can contribute to future movement, moisture issues and maintenance problems.
10. Incomplete Finishes at Handover
Many PCI inspections reveal items that have simply not been completed or require adjustment before handover.
These may include:
- Missing hardware
- Doors requiring adjustment
- Damaged architraves or skirting boards
- Unpainted areas
- Missing screws, caps or trims
While often considered minor, these items should be addressed before accepting handover.
Why Independent New Build Inspections Matter
Many homeowners assume a new home will be free from defects. However, even well-managed construction projects can contain workmanship issues that require attention before completion.
Independent inspections help identify concerns before they become hidden behind finishes or before the builder’s maintenance period expires. They provide homeowners with peace of mind and an opportunity to have defects addressed before taking possession of the property.
