Testimonials

High standard and reasonably priced

This is to certify that Weldtec has been used extensively by myself for the installation of multiple Diesel Gensets in key infrastructure facilities at various South Island locations in the last 8 years.

The work assigned to Weldtec typically has involved the supply, fabrication and installation of EPA / Worksafe compliant diesel fuel systems and the fabrication/installation of often complex exhaust systems in both mild and stainless steel, as well as seismic fixing of large diesel engines and associated bulk fuel tanks.

As former National Sales Manager for GoughCat (Power Systems)  and more recently having been employed in a similar role with Allightsykes NZ, I can confirm that the work undertaken by Johno was in all instances of a high standard and reasonably priced. I would have no hesitation in recommending Weldtec to others or indeed using Weldtec for similar such works in the future.

3. John is excellent at what he does. 5 star!

A first class job!

I would recommend Weld-Tec Canterbury to anyone not only does Johnno do a first class job he puts his customers first which is hard to find in a contractor.
In our field, if the doors aren’t open we are not making money & we need to be able to rely on our contractor’s to ensure that we can service our customer’s needs.
Johno is not afraid to put in the big hours to get the job done and get it done right.
