About Builders Waikato
South Waikato's Trusted Extension Builder
Ben started Builders Waikato because South Waikato homeowners were being let down: quoted low, hit with undisclosed variations, and left to deal with non-compliant structural work. We built this company on a different model: one Licensed Building Practitioner, one phone number, the same person on-site from the first conversation to the final Code Compliance Certificate.
- Licensed Building Practitioner (LBP)
- Written Estimates with Itemised Line Items
- South Waikato Locals
Our Guarantee
Three Explicit Promises. No Fine Print.
The 10-Year LBP Structural Warranty
All Restricted Building Work is completed under Ben's LBP licence to NZS 3604.
The 12-Month Post-Completion Walkthrough
Exactly 12 months after handover, Ben personally returns to inspect and fix any settlement adjustments.
No Unapproved Variations
If unexpected work arises, we stop, document it, and present a written variation. Nothing proceeds without your approval.
Client Feedback
What Our Clients Say
"We have used plenty of builders over the years and the difference with Builders Waikato is the follow-through. Issues get sorted, calls get returned. The extension looks amazing and we have had a dozen compliments from neighbours."
