A warranty claim arriving eighteen months after a job is not a memory contest you will win. Whatever was recorded at the time is the only version of events that still exists — and if nothing was recorded, the customer's account is the only one on the table.

Documentation is what decides the argument
A warranty claim arriving eighteen months after a job is not a memory contest you will win. Whatever was recorded at the time is the only version of events that still exists, and if nothing was recorded, the customer's account is the only one on the table.
This is not about distrusting customers. Most claims are honest, and good records resolve those faster and more generously than bad records do.
Photograph the condition you inherited
The single highest-value habit in this trade is photographing the existing condition before touching anything. Pre-existing damage, prior workmanship, moisture staining, whatever is already there. It takes two minutes and it settles a category of dispute that would otherwise be unwinnable.

The work nobody will ever see again
Anything that gets covered — connections, fasteners, flashing, substrate, anything behind a wall or under a finish — should be photographed before it is concealed. When a claim arrives, this is the evidence that matters, because the alternative is opening the assembly to find out.
Record what you installed
Product, model, batch or lot where it exists, supplier and date. Manufacturer warranties depend on it, and a material defect claim you can push to the manufacturer is a claim that does not come out of your margin.
Written scope and exclusions
Half of what gets called a warranty claim is a scope disagreement. A signed scope naming what was included and, more importantly, what was not, converts most of those into short conversations. Verbal exclusions do not survive eighteen months.
Close the job formally
A walkthrough at completion with the customer, photographs of the finished work, and a signature or written confirmation that the work is accepted. That moment is where the responsibility line gets drawn, and it is free.
Keep it where you can find it
Records that exist on a technician's personal phone do not exist. Everything should land in one place organized by job, and it should survive that technician leaving. The most common documentation failure is not a missing photograph, it is a photograph nobody can locate.
When the claim actually comes
Pull the file before you respond. Read the scope, look at the photographs, and answer from the record rather than from memory. Respond quickly and factually — speed and specificity together defuse most claims before they escalate.
Where to start
Photograph the existing condition, photograph everything before it is covered, record the products installed, get the scope and exclusions signed, close with a documented walkthrough, and store it all by job somewhere that outlives the person who took the pictures.
Two minutes of photographs settles a category of dispute that is otherwise unwinnable.
We help service businesses build the documentation habits, the scope language and the storage that make warranty claims short conversations instead of arguments.
Frequently asked questions
What should I photograph on every job?
Three things. First, the existing condition before touching anything — pre-existing damage, prior workmanship, moisture staining — which takes two minutes and settles a category of dispute that would otherwise be unwinnable. Second, everything that will be concealed: connections, fasteners, flashing, substrate, anything going behind a wall or under a finish. When a claim arrives, that is the evidence that matters, because the alternative is opening the assembly to find out. Third, the finished work at the completion walkthrough. Alongside the photographs, record the product, model, batch or lot, supplier and date for what you installed.
How long should I keep job records and where?
Long enough to cover your warranty period and any statutory exposure in your jurisdiction, and in one place organized by job rather than on individual phones. Records that live on a technician's personal device do not exist, and the most common documentation failure is not a missing photograph but one nobody can locate. Make sure the storage survives that technician leaving. When a claim does arrive, pull the file before responding, read the scope, look at the photographs and answer from the record rather than from memory — speed and specificity together defuse most claims before they escalate.
