Recording Evidence for a Screed Floor Dispute

As soon as a defect is noticed, photographs with a visible scale reference and date, alongside a written description of location and symptoms, form the baseline record. Any existing documentation, the original screed specification, drying schedule, moisture test certificates and handover sign-offs between trades, should be gathered and preserved rather than left with individual contractors.

Where testing is needed to establish the cause, using a consistent, standards-based methodology and recording exactly how and where each reading was taken avoids the record being dismissed later as unreliable or unrepresentative.

Because a screed defect can originate at any point from substrate preparation through to floor covering installation, a chronology listing which trade was on site, what work they completed, and on what date, is one of the most valuable pieces of evidence a dispute can draw on. Cross-referencing this timeline against weather conditions, heating commissioning dates, and any known site incidents (a leak, a delayed handover, an early occupation) often narrows down where the problem most likely started.

Where trades overlap or handover documentation is incomplete, noting the gaps explicitly, rather than glossing over them, is more useful to a later investigation than a chronology that looks complete but omits uncertain periods.

One of the most common mistakes is allowing remedial work, such as lifting a failed floor covering, to happen before the condition has been properly documented and, where relevant, independently assessed. Once disturbed, some evidence (such as the exact bond condition or moisture distribution at the time of failure) can be lost.

Keeping a simple chronology of which trade completed which stage, and when, alongside the evidence gathered, makes it much easier for whoever is assessing the dispute, whether that's an insurer, a court, or the parties themselves, to reach a fair view of where the problem originated.

A dispute is far more likely to be resolved efficiently where the evidence is presented as a single, organised file, photographs labelled by date and location, test results referenced against the standard used, and a written summary tying the chronology to the physical findings, rather than as a loose collection of documents handed over piecemeal. Numbering photographs and cross-referencing them to a simple floor plan helps anyone unfamiliar with the site understand exactly where each piece of evidence relates to.

Where technical readings are involved, a short plain-language summary alongside the raw data helps non-specialist parties, such as an insurer or a homeowner, follow the reasoning without needing to interpret standards documents themselves.

Where more than one trade is potentially involved, or where the value of the dispute is significant, commissioning an independent surveyor to review or repeat key tests adds a layer of objectivity that self-gathered evidence alone cannot fully provide. Independent input is particularly valuable where the parties disagree not just on responsibility but on the underlying facts, such as whether a moisture reading was taken correctly in the first place.

Bringing in independent expertise early, rather than only once a dispute has escalated to formal proceedings, is generally the more cost-effective route, since it can sometimes resolve a disagreement before legal costs become a significant factor in their own right.
