Ashburton homes often mix older brick builds with renovated extensions—major defects can hide where new work meets original walls, roofs and subfloors, especially after years of moisture movement.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess cracking patterns to distinguish typical ageing from movement that may indicate footing issues, wall separation, or compromised load paths. This matters in Ashburton renovations where original masonry and newer extensions can settle differently and create stress points.
We check for sagging, rot, inadequate supports, water entry and ventilation issues that can lead to structural softness and long-term failure. Subfloor moisture problems can also accelerate timber decay and cause doors and floors to go out of level.
We inspect roof lines, flashings, valleys, gutters and internal roof space indicators for signs of water entry and structural weakness. Roofing defects matter because ongoing leaks can damage framing, ceilings and insulation before a stain appears inside living areas.
We look at bulging walls, displaced bricks, and stressed openings around windows and doors. Where rooms have been reconfigured, we flag indicators that a lintel or beam may be undersized or poorly supported, which can become a major safety issue.
We check bathrooms, laundries and kitchens for tell-tale signs of failing waterproofing such as swelling, lifted finishes, mould patterns and moisture impact to adjoining rooms. Persistent leaks can damage framing and subfloors and may require strip-out repairs.
While we don’t certify electrical or plumbing work, we identify visible signs that warrant urgent specialist review—unsafe wiring indicators, improvised connections, water pressure anomalies, and moisture around services. These issues can present real fire, shock, or water-damage risks.

A major defect is an issue that can materially affect structural integrity, safety, or the building’s ability to perform as intended. In Ashburton, that often includes significant movement cracking, compromised subfloor supports, ongoing roof leaks affecting framing, and alterations that appear to remove or weaken load-bearing elements. We document the indicators, explain the likely implications, and recommend appropriate specialist assessment where needed.
Yes. Renovations can conceal problems behind new linings, tiled wet areas, or ceiling bulkheads. Extensions can also introduce differential movement between original and new construction, leading to cracking, roof junction leaks, or unsupported openings. Our inspection focuses on the junctions and “change points” where defects commonly appear, and we note any access limits so you know what may need further investigation.
We look for visible signs consistent with footing movement, including stepped brick cracking, gaps at skirtings, uneven floors, and distorted openings. Where accessible, we also inspect subfloor conditions that can contribute to movement, such as moisture, drainage issues, or deteriorated supports. If the indicators suggest structural instability, we’ll recommend a structural engineer for confirmation and repair design.
They can be, particularly where mature trees, garden beds, and changed drainage patterns influence ground moisture levels around the home. Movement risk tends to show up as recurring cracks, sticking doors, and uneven flooring, especially after seasonal wet/dry cycles. We assess the building for movement indicators and note external conditions such as water run-off paths and moisture-prone areas that may be contributing to ongoing stress.
Yes. We prioritise findings so you can act on the items that pose immediate risk to safety or structural performance, and we separate those from defects that may be monitored or handled as planned maintenance. The report includes photos and plain-English explanations, plus guidance on when to bring in specialists (such as roofing, plumbing, electrical, or engineering) to quote accurately.
