Keeping Records That Support a Render Warranty Claim
When a defect shows up in render years after handover, the first question is what went on the wall. Without records, nobody can answer it with confidence. Claims slow down and costs get argued over.
Good records take little effort at the time. They make any later claim far simpler for the builder, the contractor and the owner.
Record the system
Write down exactly what was applied:
- Manufacturer and system name
- Product names for each coat
- Texture and colour code
- Substrate for each elevation
This is the foundation of any claim. Product and workmanship warranties usually depend on the right system being used on the right substrate.
Keep delivery dockets
These show which products arrived and when. Some products carry batch numbers. If a product fault is suspected, the manufacturer will ask for these details.
Take stage photos
Photograph the work before it gets covered:
- Substrate ready for coating
- Mesh and base coat, especially at openings and corners
- Finished wall on each elevation
Label photos by lot, elevation and date. A photo with no label is hard to use in a claim.
Note the weather and dates
Record the dates each coat was applied. If there was rain or extreme heat around those dates, note it. Curing conditions come up often when a coating fails early.
Record site changes
If a detail changed during the job, write it down and mark it on the drawings. Changes at openings or control joints are especially important.
Handover information for the owner
Give the owner simple care instructions. Tell them how to clean the walls, what to avoid and who to contact if they see cracking or staining. Owners who report problems early usually get simpler fixes.
Report defects promptly
Most warranties expect defects to be reported within a reasonable time. Delays can make a small repair bigger and can complicate cover. When a defect is reported, photograph it straight away.
When a claim comes in
When an owner reports a problem, act quickly. Visit the site, photograph the defect and note its size and position. Pull the records for that lot before calling the contractor or the manufacturer.
With the system details, dates and photos in hand, the cause is often clear after one visit. Without them, everyone starts from guesswork and the claim drags on.
Store it where you can find it
A folder for each lot, kept for the life of the warranty, is enough. Make sure someone other than the site supervisor knows where it is.
