Family-run, out of Te Kūiti
The crew behind the build
RB Thomas is a small, family-run outfit — started and still run by Jake and Faye Thomas. Small by choice: you deal with the people actually doing the work, decisions get made fast, and nothing slips through the cracks.
Straight-up advice, honest quotes, and a team that genuinely enjoys turning your place into something you love.
Reviews
Don’t just take our word for it
“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.”
Craig “Highly recommend! These guys were awesome, professional, clean, communicative and had a high standard of work. Worked within our budget, made suggestions around savings and provided a fixed quote, which they stuck to. We renovated a 1980s bathroom, toilet and shower area. Will definitely use again for our kitchen reno. 10/10!”
Ragan Clancy “Jake and his team did a fantastic 120sqm extension on our home in the Waikato. Jake & Faye are easy to deal with and listened to our requests and delivered exactly what was quoted & promised, to an outstanding quality and workmanship.”
Anton O'Connell “The whole process was so easy. All my questions answered, replies were never a day late and always updated all the way through. The workers were polite, kind, tidy and efficient. The work on my house is beautiful, I love it — definitely got my money's worth. So thank you to Jake and his team, made my first experience with builders a great one.”
Samantha Tata “We have been working with RB Thomas Ltd in various scenarios for a number of years and always find them great to work with. We can 100% recommend Jake & the team, we will have no hesitation in working with them again in the future.”
Smith & Sons South Waikato “RB Thomas Ltd in Te Kūiti is an absolute gem. Their team is professional, friendly, and genuinely committed to getting the job done right the first time. From start to finish, the service was prompt, efficient, and full of those extra little touches that make you feel valued as a customer.”
