About us

We are family

Established in 2015, RB Thomas Limited is a small family-run construction company run by Jake and Faye Thomas. Being small makes us nimble. We’re able to move more efficiently to deliver you awesome products and services, while keeping a lid on overheads, which saves you money. Rain or shine, we love nothing more than bringing your dreams to life and the smiles that accompany them.

Building your trust in us

Building’s not just about hammers and nails, it’s about relationships too. The best way we know to build trust is to always do what we say we’ll do. And always be straight up with you. We’ll tell you if something won’t work. We’ll look beyond your brief to get the right result. And we’ll stand by every quote, even if it costs us. That’s just who we are.

We’re New Zealand Certified Builders

Most people have only ever heard of Master Builders, because of all the TV ads. But we firmly believe the New Zealand Certified Builders Association (NZCB) is better for both you and the industry. What’s more, it’s the only builder association with strict entry criteria that include minimum qualifications and stringent background checks. So you can be sure your job’s in good hands.

Our 10-year guarantee

When you get us on the job, you get the peace of mind of knowing our work is covered by the 10-year implied warranty set out in the Building Act 2004. On top of this, our membership of NZCB means we can also offer you access to Halo – the comprehensive 10-year residential guarantee.

A great team around us

We work with suppliers and subcontractors who make us look good.
