Modular Home Warranties Explained: 30 Days, 7 Years, and Beyond

Modular home warranties are an underrated buyer protection. Done well, they cover defects from the first day through years of normal living, with multiple overlapping protection periods. Done badly (read: at some builders), they are full of exclusions and exceptions that surprise owners at the worst time. Here is how Hi-Tech's warranty framework works in 2026 and what every modular buyer should ask their builder.

The Three Warranty Periods

1. Defect liability period (typically 30 days to 6 months)

The handover-to-settling-in period. Cosmetic defects, missing components, small issues you notice as you move in. Quick fixes by the builder.

2. Structural warranty (6 to 7 years in NSW)

NSW Home Building Compensation Fund (HBCF) and the Home Building Act both cover structural defects for 6 years (now 7 in some categories) from completion. Foundation movement, structural cracking, major waterproofing failures all sit here.

3. Non-structural warranty (typically 2 years in NSW)

Minor defects covered for 2 years. Plaster cracking from normal settling, paint, tile grouting, hardware failures.

Component Warranties

Inside the home, individual components carry their own manufacturer warranties: appliances (1 to 10 years depending on item), roofing (10 to 50 years), cladding (10 to 25 years), windows (10 to 20 years), solar panels (10 to 25 years). We provide a documentation pack at handover with all component warranties consolidated.

What Voids a Warranty

• Modifications by unlicensed trades
• Failure to maintain (e.g., never clearing gutters)
• Storm damage or vandalism (insurance, not warranty)
• Wear and tear from normal use

The Modular Advantage

Factory-built homes typically have fewer warranty claims than on-site builds because: same crew builds the same components every day, QA loop catches issues before delivery, materials are sourced and verified systematically, weather is not a variable during construction.

Questions to Ask Your Builder

• Are you licensed to issue HBCF cover?
• What is your defect liability period?
• Do you provide a consolidated component warranty pack?
• How do you handle warranty service requests after handover?
• What is your record of warranty claims?

Hi-Tech has been operating in NSW for 30+ years. Our track record answers most of these for you.

Pre-Loved Home Warranties

For pre-loved modular homes, original structural warranties may still be in force if the home is under 6 years old. We disclose the warranty status of every pre-loved home before purchase.
