Construction Defect Investigation

When a building problem traces back to how it was designed or built, documenting the defect clearly matters — for repair planning, and for any dispute that follows. A construction defect investigation identifies what went wrong and how it happened. This is more thorough than a standard construction inspection — we compare as-built conditions against plans, codes, and manufacturer requirements.

Common signs

  • Problems appearing shortly after construction or renovation
  • Water intrusion at multiple similar locations
  • Components installed contrary to manufacturer specifications
  • Recurring failures despite repairs
  • Discrepancies between plans and as-built conditions

Potential causes

  • Design errors or omissions
  • Installation not matching manufacturer requirements
  • Code or standard-of-care deviations
  • Incompatible material substitutions
  • Inadequate quality control during construction

What we test and document

  • Site investigation and documentation
  • Comparison against plans, specifications, and manufacturer guidelines
  • Material and assembly testing
  • Photographic and written documentation suitable for review

What you receive

A written report comparing observed conditions against plans, codes, and manufacturer requirements, documenting the defect and its likely cause.

Investigator vs. contractor

A contractor is often right when the source of a problem is already known. An independent investigation is worth it when the source isn’t clear, a previous repair didn’t work, or you need documentation you can rely on before spending money on repairs.


Common questions

Is this the same as a home inspection?

No — a construction defect investigation examines installation against plans, codes, and manufacturer requirements to determine whether a defect exists.

Can this support a claim against a builder or contractor?

Documentation is prepared to be clear and defensible. Let us know upfront if a dispute or claim is anticipated.

Do you work with attorneys on these investigations?

Yes — field investigation and documentation for construction defect matters, including support for attorneys, is part of what we do.
