Questions to Ask Your External Plasterer in Auckland Before Starting a Job

Published on

October 6, 2025

When it comes to having a flawless finish on your home’s external cladding, exterior plastering delivers the right result. Whether you're building new, embarking on a home renovation, or repairing weather damaged walls, choosing the right plasterer in Auckland can make all the difference. But how do you know you're hiring the right professional?

At West & Sons Construction, we’ve worked across hundreds of homes in Auckland, and we know what separates a quality job from a costly mistake. We have been plastering for over 100 years, passing the skill down for four generations through the West family. We like to think we are good at what we do. Here are the top questions you should ask your plasterer in Auckland before any work begins, especially if you're investing in exterior plastering, plastering and rendering, or exterior plastering repairs in Auckland.

Read our latest blog for more information on Why Professional Plastering Services Are Essential for Auckland Renovations.

Are You a Licensed Building Practitioner (LBP)?

This is the first and most important question to ask. In New Zealand, certain types of building work, especially those affecting the structure or weather tightness of a home, must be carried out or supervised by a Licensed Building Practitioner (LBP).

If your project involves external plastering or exterior plastering repairs in Auckland, hiring an LBP ensures the work meets the New Zealand Building Code and is legally compliant. It also gives you peace of mind that your plasterer has the qualifications, experience, and accountability to do the job right. We are Licenced Building Practitioners across several trades and are committed to ongoing, life long learning.

For examples of Restricted Building Work (RBW), where a Licensed Building Practitioner is required, please read our recent blog; Restricted Building Work, Why you Need a Licensed Building Practitioner.

What Experience Do You Have with Exterior Plastering in Auckland’s Climate?

Auckland’s coastal climate presents unique challenges for exterior finishes. High humidity, salt air, and heavy rainfall can all impact the longevity of your plasterwork. That’s why it’s crucial to hire a plasterer in Auckland who understands how to work with materials that can withstand these conditions.

Ask about:

The types of exterior plastering systems they use (e.g., cement-based, acrylic, or polymer-modified).
Their experience with plastering and rendering on different surfaces like brick, concrete block, or fibre cement.
How they handle waterproofing and drainage to prevent moisture ingress.

A seasoned Auckland plasterer will be able to recommend the best solution for your home and explain how their methods protect against the elements.

If your plastering and rendering project requires matching old and new finishes, read our recent blog to understand how this is tackled.

What’s Included in Your Quote, Are There Any Hidden Costs?

Not all renovation cost estimates and quotes are created equal. Some Auckland plasterers may offer a low upfront price but tack on extra charges later for scaffolding, materials, or site cleanup. To avoid surprises, ask for a detailed written quote that includes:

Labour and material costs
Surface preparation
Scaffolding or access equipment
Waste removal
Timeframes for completion
Payment schedule

Also, clarify whether the quote includes exterior plastering repairs if any issues are discovered during the job. A transparent Auckland plasterer will be upfront about potential costs and timelines.

What Maintenance and Warranty Do You Offer?

Even the best plastering and rendering work needs occasional maintenance, especially in Auckland’s variable weather. A good exterior plasterer should provide guidance on how to care for your new surfaces and offer a warranty on their workmanship.

Ask:

How long is the warranty?
What does it cover (e.g., cracking, delamination, water ingress)?
What maintenance is required to keep the warranty valid?

For exterior plastering repairs in Auckland, this is especially important.
