A defect notice (notice of defects) is the client’s formal notification to the contractor that a delivered work does not conform to the contract. It describes the defect concretely, demands rectification within a reasonable deadline and secures the client’s warranty rights.
What must a defect notice contain?
- Concrete description of the defect — what, where, to what extent (symptoms are enough; finding the cause is the contractor’s job)
- Exact location — building element, floor, room, ideally with a markup on the drawing
- Photo documentation with date
- A reasonable deadline for rectification
- Provable delivery — receipt must be verifiable
The most common mistakes with defect notices
In practice, warranty claims rarely fail on the law — they fail on documentation: the defect was only reported by phone, the photo cannot be attributed, the deadline was never set in writing, or the sequence (notified → reworked → defective again) cannot be proven.
A defect notice without provable receipt and without located photo documentation is worth little more than a phone call in a dispute.
Notifying and tracking defects digitally
With defect management in XBuild the court-proof chain builds itself: capture the defect with photo and pin on the drawing, assign it to the trade with a deadline (automatic, provable notification), track the status — and every step lands in the tamper-proof activity log. At acceptance you generate the complete defect protocol in one click.
Frequently asked questions: defect notice
What deadline applies to a defect notice?
The defect should be notified without delay after discovery. For rectification, a reasonable deadline is set — typically 1–4 weeks depending on scope.
Does a defect notice have to be in writing?
For evidential reasons: absolutely. What counts is provable receipt by the contractor — e.g. via documented digital delivery.
What is the difference between a defect notice and a notice of defects?
The terms are used largely synonymously; both describe the formal report of a defect to the responsible party.
