Most cladding sales conversations are steered by the supplier — colours, finishes, how nice it’ll look. Fair enough, that’s the fun part. But the questions that actually protect you from a bad decision fifteen years from now rarely come up unless you ask them yourself. Here they are.
1. What’s the actual warranty, and what does it exclude?
Ask for the document, not a verbal summary. Every warranty has exclusions — the question is whether they’re reasonable (impact damage, unauthorised installation) or whether they quietly cover almost nothing (see our full warranty breakdown for what a fair one should look like).
2. Is this panel fire-tested, and can I see the certificate?
Not every cladding material handles this the same way, and it’s not always volunteered upfront. A supplier confident in their product will have the test certificate ready to show, not promised for later.
3. Who’s actually doing the installation, and does that affect my warranty?
Some warranties are voided by unauthorised installation, which matters a lot if a contractor offers to install a supplier’s panels at a discount outside their official installer network. Ask this before you save money on installation and lose your coverage doing it.
4. What does routine maintenance actually involve, honestly?
“Low maintenance” gets said about almost everything. Ask specifically: does it need recoating, resealing, or any periodic treatment beyond a basic wash? The answer tells you a lot about the real 15-year cost, not just the installation cost.
5. How does this material perform against water, specifically at joints and corners?
The panel material itself is rarely where water problems start — it’s almost always at joints, corners, and window returns. Ask how those are detailed and sealed, not just whether the flat panel is waterproof.
6. What happens if a panel gets damaged years down the line — can it be replaced individually?
A modular panel system should allow a single damaged section to be replaced without redoing the whole wall. Confirm this is actually how the system works before you need it.
7. Can I see a real installation that’s several years old, not just a fresh one?
Fresh installations always look good. A facade that’s three, five, or eight years old tells you far more about how a material actually ages in real conditions than a showroom sample or a day-one photo ever will. A supplier with genuine confidence in their product should be able to point you to one.
Why these questions matter more than the finish catalogue
The colour and texture decisions are reversible in the sense that you’ll live with them happily either way, most likely. The answers to these seven questions are the ones that determine whether you’re dealing with a genuine 15-year investment or a five-year regret with a nice-looking day-one photo.
FAQ
Should I ask these same questions of a paint contractor too?
Some translate directly — ask any contractor about warranty, what maintenance actually involves, and whether they can show older completed work, regardless of material.
Is it reasonable to ask a supplier all seven of these before even getting a quote?
Yes, and a supplier who takes these seriously rather than brushing past them is generally a good early signal about how the rest of the process will go.
What’s the single most important question on this list?
Probably the warranty exclusions one — it’s the question most likely to reveal a gap between marketing promises and what’s actually covered.
