Modular Building Warranty: What’s Covered and How Aruva’s 7+1 Warranty Works

If you’re investing in modular accommodation—whether it’s for workforce housing, essential services, mining, government, or remote infrastructure—there’s one question that comes up nearly every time:

“What’s the warranty?”

It’s a fair and practical question.

You’re making a capital investment. You need to know how long it’s protected, what’s covered, and where the responsibility sits if something goes wrong.

This article breaks it down in plain terms. No spin. No sales talk.

Just a straight answer to a question that anyone buying modular buildings should be asking.

How Do Warranties Work on Modular Buildings in Australia?

Speaking purely from what we see in the market, warranty terms can vary significantly across modular suppliers.

Broadly speaking, most warranties split into two categories:

• Major Defects Warranty – covers things that affect the building’s structural integrity. If something happens that makes the building unsafe, unstable, or seriously compromised, this is the warranty that applies.
• Minor Defects Warranty – covers finishing touches and operational details. These are issues that don’t affect the building’s ability to function but still need fixing. Think cracked cornices, loose door handles, or minor alignment issues.

Under Australian law, major defects are typically covered for six years, and minor defects for about one to two years, depending on the state. More information on these statutory warranties can be found at the Master Builders Association.

That’s the minimum.
But we’ve observed that not all modular buildings meet the same standards—especially with reports circulating about lower-cost imported products that don’t always perform as expected.

This has led to a growing number of complaints from asset owners facing premature failures, warranty headaches, or costly repairs.

That’s why it’s absolutely reasonable—and smart—to ask exactly what warranty coverage looks like when assessing modular building suppliers.

What Warranty Does Aruva Provide on Modular Buildings?

Every modular building supplied by Aruva comes with the following:

• 7 Years – Major Defects Warranty
  Covers the backbone of the building—structural components, framing, roof, walls, subfloor systems, and anything that affects the safety and stability of the structure.
• 1 Year – Minor Defects Warranty
  Applies to the smaller stuff that tends to show itself in the first 12 months of use. Cosmetic finishes, fittings, minor movement cracks, loose joinery, or adjustment-type items.

This warranty applies across the board, no matter the project size or type—whether it’s a mining camp, government facility, emergency accommodation, or remote workforce housing.

It’s one of the reasons why managers who are smart about their investments in the people they’re providing for—whether that’s staff, community members, or clients—pay close attention to warranty terms when choosing modular infrastructure. It’s not just about the building; it’s about long-term performance and avoiding unexpected downtime.

What Is a Pass-Through Warranty on a Modular Building?

Not everything in a modular building is built by the builder.

Some components—like air conditioning systems, roofing materials, specialist cladding, or appliances—come from third-party manufacturers.

These items carry their own manufacturer warranties, which pass directly to you as the building owner.

For example:

• An air conditioner might come with a 5-year compressor warranty
• A roofing product might have a 15-year manufacturer warranty against corrosion
• Certain cladding systems might carry warranties for fade resistance or weather performance.

These warranties are independent of the builder’s warranty but run in parallel. If a cladding manufacturer offers a 20-year product warranty, that’s on top of Aruva’s 7-year structural cover.

What’s Not Covered in a Modular Building Warranty? (The Common-Sense Stuff)

Every warranty has boundaries. It’s designed to cover product defects—not the wear and tear of normal life or damage from external events.

Here’s what generally isn’t covered:

• Misuse or neglect. If the building isn’t maintained, misused, or altered in a way that causes damage, it’s outside the warranty.
• Extreme environmental damage. Floods, cyclones, fires, or other disasters aren’t warranty issues; that’s what insurance is for.
• Unauthorised modifications. If structural or functional changes are made after delivery without approval, coverage doesn’t apply to those areas.
• Normal wear and tear. Things like fading paint, worn flooring, or cosmetic deterioration over time.

The full warranty document spells out the details, but in short—it’s based on fair use under expected conditions.

Why a Modular Building Warranty Matters for Your Investment

If you’re managing assets, this isn’t about whether things might go wrong—it’s about knowing that if something does, you’re covered.

A strong warranty is about risk management. It means:

• You have protection against manufacturing or construction faults.
• You avoid unplanned costs from structural failures.
• You maintain uptime for the assets you rely on—whether that’s worker accommodation, emergency housing, or remote infrastructure.

It’s one of the reasons why property managers who prioritise the wellbeing and performance of their teams tend to look closely at not just the upfront cost of modular buildings, but the long-term reliability, support, and protection that comes with them.

From what we can speak for, warranty claims on Aruva buildings are extremely low.

These buildings are engineered for Australian conditions, built to high standards, and designed to perform reliably over time. When systems are designed right and built right, they deliver what’s expected—and our claims history reflects that.

At the same time, we’re aware of growing concerns in the market about cheaper imported modular units that don’t always meet expectations. We won’t comment on the specifics of other suppliers, but it’s a reminder of why due diligence around warranty and quality should be part of every procurement decision.

The Straightforward Breakdown of Aruva’s Modular Building Warranty

Here it is, boiled down:

• 7 Years – Major Defects Warranty
  Covers the structure: walls, floor systems, roofs, frames, and key load-bearing elements.
• 1 Year – Minor Defects Warranty
  Covers cosmetic issues, minor hardware faults, or anything that crops up in the first year.
• Pass-Through Manufacturer Warranties
  Applies to components like air conditioning, roofing, cladding, and specialist systems. These are honoured according to the individual manufacturer’s terms.
• Exclusions apply, as expected – misuse, abnormal environmental events, unauthorised changes, and normal wear aren’t covered.

It’s a formal commitment that covers the real-world outcomes expected from the materials, construction methods, and processes used. It also aligns with Aruva’s approach to delivering buildings that perform over time in Australian conditions.
