Construction claims: experts for defects, sites and structures

A claim with many possible payers

Unlike a burst pipe at home, a construction problem often involves several parties: the owner, the main contractor, subcontractors, designers, suppliers and their respective insurers. Contractors' all-risk cover, professional indemnity, latent defect or decennial-type insurance and the owner's own property policy may all be relevant, each with different triggers and time limits.

The first technical question is therefore not only how much the repair will cost, but what caused the damage and at which stage of the project it originated. That answer determines which policy responds.

Topics covered in this family

The guides below cover the situations most often met by owners and builders.

• Construction defects discovered after handover, such as leaks, failing finishes or faulty services
• Accidents and damage on building sites during the works
• Long-term liability for structural defects after completion, where such regimes exist
• Cracks, settlement and structural movement in existing buildings
• Construction insurance programmes and how their covers interact

Experts on the insurer's side and on yours

Insurers typically appoint a building surveyor or engineer to investigate the cause and scope of the damage. An owner can commission an independent structural engineer, building surveyor or policyholder-side claims expert to check the diagnosis, the proposed repair method and the costing. In litigation, a court may appoint its own expert, whose report often carries considerable weight.

Typical grounds for dispute

Disagreements usually concern the origin of the defect (design, workmanship, materials or normal wear), whether the damage affects the strength or usability of the building, the extent of the repair needed, and whether a cheaper patch repair is acceptable instead of a full replacement. Deadlines for notification and for bringing a claim are another frequent battleground.

Finding the most relevant guide

If works are still ongoing, start with the building site guide. If the problem appeared after handover, read the construction defects page, then the long-term liability guide where your country has such a regime. Cracks in an older building usually belong to the structural damage page, which also discusses ground movement. Each topic has a matching page on the cost of hiring an independent expert.

Records that strengthen a construction claim

Keep the contracts, plans, specifications, handover documents and any snagging lists. Photograph the damage with dates and measurements, and avoid destructive repairs before the experts have seen the evidence unless urgent safety work is required.

Timelines that shape construction claims

Construction disputes often run for months or years, because the cause must be established before anyone accepts responsibility. Investigations may require opening up walls, testing materials, monitoring cracks over several seasons or reviewing design calculations. Meanwhile, the building may need temporary protection or partial use.

Insurers and contractors sometimes agree on a joint expert to avoid duplicated testing, which can save time and cost if the mandate is clearly defined. Owners should still make sure the questions put to that expert cover their own concerns, including consequential costs such as relocation or loss of rent. Recording every deadline in a single timeline, from handover date to notification and limitation periods, is one of the simplest and most effective protections.
