CZT Contractors Ltd isn’t a faceless building company. It’s a business built by Shaun Sanderson—a builder who started with nothing but tools, talent, and a passion for fixing things right.
Now, after 9 years in the trade and dozens of projects across Auckland, CZT has become a name locals trust for repairs done properly, without overcomplicating things.
We don’t just patch problems. We find the cause, fix it, and leave your home better than we found it. And because we manage all trades in-house, you won’t be left coordinating different contractors. One call to us—and it’s sorted.
Whether it’s old age, weather damage, or a previous bad reno job—we can fix it. Our most common repair services include:
Rotten Timber & Weatherboards – Especially common in Auckland’s damp conditions
Wall Cracks & Gib Repair – From small cracks to major movement fixes
Leaky Windows & Door Frames – We reseal and repair to keep moisture out
Decking Repairs – Replace broken boards, realign framing, or reinforce the structure

Not sure if it’s a repair or a full replacement? We’ll assess the damage and give you honest advice.
