NZCB Certified
Waikato Builders
Renovations, restorations, recladding, new home builds, commercial work and building inspections — right across the Waikato.

Trusted builders for the whole Waikato region
RB Thomas is a family-run, NZCB-certified building company based in Te Kuiti. For more than 20 years we’ve been building, renovating and restoring homes across the Waikato — from the heart of Hamilton to the rural towns of the King Country and South Waikato. Whatever the project, our promise is the same one we’ve built our name on: projects on spec, on time, on budget. Every time.
We handle everything from a single bathroom renovation to a full custom new build, leaky-home recladding, commercial fit-outs and independent building inspections — and every residential job can be backed by the Halo 10-Year Residential Guarantee.

Why choose a local Waikato builder
The Waikato has its own mix of housing — from early-1900s villas and ex-state homes to lifestyle blocks and brand-new subdivisions. A builder who works here every day knows that stock, knows the local councils and their consent quirks, and has relationships with the merchants and trades that keep a project moving.
With RB Thomas you get builders who are genuinely local, genuinely certified, and genuinely accountable — the kind who answer the phone and stand behind their work long after the job’s done.
They said it, not us
“I have had the privilege of using Jake as a builder and project manager on numerous occasions. I can honestly say you will never find a more honest and genuine man. His workmanship is second to none and he communicates through every step of the build/renovation and makes sure you understand the process. I couldn't recommend him highly enough.”
