RB Thomas Ltd is a family-owned, fully certified building company proudly serving the Waikato. Founded by Jake and Faye Thomas, we deliver high-quality construction and renovation services with honesty, clear communication, and a commitment to completing every project on time and within budget. As members of the New Zealand Certified Builders Association (NZCB), we offer exceptional workmanship backed by industry-leading protection. Our clients receive complete peace of mind through two powerful guarantees:
A 10-year implied warranty under the Building Act 2004
Access to Halo — the comprehensive 10-year residential guarantee available exclusively through NZCB

This dual guarantee ensures every renovation and build is protected long after the work is complete. RB Thomas Ltd specialises in full home renovations, kitchen renovations, bathroom renovations, and outdoor renovations. Our team also delivers commercial builds, barn-style home construction, and detailed non-invasive building inspections. Our inspection reports cover the property’s exterior, interior, subfloor, roof spaces, site, and drainage — giving buyers and homeowners clarity before making important decisions.

We proudly work across the Waikato region, including Hamilton, Cambridge, Matamata, Te Awamutu, Ōtorohanga, Waitomo, Te Kuiti, and Tokoroa. Whether you’re renovating, building new, planning a commercial project, or needing a professional inspection, RB Thomas Ltd offers trusted craftsmanship, transparent service, and long-lasting results.
