Jase knows his stuff and is trustworthy to get the job done,his workmanship is top notch with reasonable prices. I have used Jase in the past as well and have chosen him this time as well to do this job since he is not some cowboy and he’s fair in his job quotes which fits in the budget. Definitely highly recommended and I will use him and his company for any future jobs.Thanks Jase Harder and CTS waikato for helping me get it done.

CTS Waikato are really awesome. They’ve taken care of our plumbing 3x now (all separate issues, and not related to any of their previous work). First job was an emergency and Jase came within a couple of hours and had everything sorted in no time. The team are super efficient and always try to get a good idea of the job before they arrive so they can bring the necessary parts to save time (and ultimately, my money). So glad we’ve found these guys. If you have any plumbing needs and want a fair price and a job done properly, I would 100% recommend Combined Trade Services Waikato.

Highly recommend Combined Trade Services!

They recently completed a full bathroom/ toilet renovation for me and I couldn’t be happier with the results. The team was fast, reliable, and incredibly trustworthy throughout the whole process. Their pricing was very fair, and the quality of their work really shows. It’s so hard to find trades you can count on these days, but CTS made everything smooth and stress-free. I’ll definitely be using them again for all future projects.

Jase is super knowledgeable and knows exactly what to check and where the fault is. He helped identify an issue with hot water supply at our rental property and fixed the issue super quick without mucking around. Highly recommended.
