What Should You Know Before Hiring A Plasterer?

Hiring a plasterer isn’t something you do every day. It’s a task that can transform the entire look and feel of your home, but it can also go terribly wrong if you choose the wrong person for the job. Over the years, I’ve seen plenty of Melbourne homes where the walls looked like corrugated iron under a fresh coat of paint — a result of hiring a cheap plasterer with little experience. 

When it comes to plastering, the difference between good and bad work is painfully obvious. This guide will walk you through the essential checks to make before hiring a plasterer, ensuring you get a flawless finish that lasts.

Why Choosing the Right Plasterer Matters

The Importance of Quality Plastering

Plastering isn’t just about slapping some mud on a wall and calling it a day. Good plastering is the backbone of any clean, professional interior. Get it right, and your paint will shine like a diamond; get it wrong, and you’ll see every lump, crack, and shadow — forever. I’ve worked on enough homes to tell you that poor plastering will haunt you long after the job is finished.

A perfect plaster job creates a flawless canvas for your paintwork. But when plastering is done poorly, every imperfection becomes glaringly obvious. Take it from me, the extra cost of a professional plasterer is worth every cent when you see the final result.

How the Wrong Plasterer Can Impact Your Home

The wrong plasterer can leave you with walls that sag, crack, and deteriorate far too quickly. I’ve had clients in Essendon who painted fresh plaster only to find it bubbling a few weeks later. They had hired a plasterer who rushed the job and didn’t let the plaster dry properly. Plaster needs time to cure in Melbourne’s damp winters, and shortcuts can lead to costly repairs down the line.

Essential Pre-Hiring Checks and Credentials

Licensing: A Must-Have for Large Jobs

Licensing is a crucial part of the plastering process in Victoria. Once your project involves work over $10,000 or for structural elements, the plasterer must be licensed. I’ve seen plenty of homeowners in areas like St Kilda and Richmond who didn’t even realise plastering required a licence until their building surveyor asked for it. It’s essential to verify the plasterer’s credentials. Don’t just take their word for it — ask to see their licence. A legitimate plasterer will have no problem showing it, while anyone who hesitates or avoids the question is a red flag.

Insurance: Protect Yourself

Accidents happen, and I’ve seen more than my fair share. Once, a ladder crashed into a brand new timber floor in a Richmond terrace. If your plasterer isn’t insured, you’ll be left picking up the bill. In Victoria, every plasterer should have Public Liability Insurance and Professional Indemnity Insurance. Public Liability covers any damage to your property or injury during the work, while Professional Indemnity covers the cost if their work turns out faulty later on. Ask for proof of insurance. A trustworthy plasterer will provide it without hesitation.

Experience: Why It Matters

Plastering is one of those jobs where experience counts for everything. I’ve been plastering homes in Melbourne for over 25 years, and it’s safe to say that I can tell within minutes if a wall is going to be trouble. That kind of instinct only comes with years of hands-on experience. Look for a plasterer with at least five years of work under their belt. Ask whether they specialise in interiors, exteriors, or heritage restorations — these areas require different techniques. For instance, a modern townhouse in Southbank might need clean plasterboard joins and square-set ceilings, while a heritage terrace in Carlton requires expertise in repairing lime plaster without destroying the building’s character.

Reputation: Word of Mouth Still Wins

In this industry, reputation is everything. The best plasterers get most of their work through word of mouth. Clients call me back year after year, or their neighbours see the work I’ve done and ask for the same finish. Online reviews can help, but look for detailed comments — something like “Great job” doesn’t tell you much. A reputable plasterer will have reviews that mention specifics like punctuality, the quality of the finish, and whether they stuck to the timeline. When it comes to plastering, a good reputation can’t be faked.

Understanding Plastering Services and Techniques

Core Plastering Techniques You Should Know

Not all plastering jobs are the same. Some plastering techniques are better suited for specific situations. Here’s a rundown of the most common methods:

Specialist Finishes That Make a Statement

If you’re after something more stylish, there are several specialist finishes to consider:

• Venetian Plaster: This polished lime plaster looks like marble and is often used in high-end areas like Toorak bathrooms. It costs around $180 per square meter, but the results are worth it.
• Moroccan Tadelakt: A waterproof finish that works wonders in wet areas like showers. I used this in a Brunswick East renovation where tiles weren’t an option, and it was a stunning success.
• Pebble Dash or Spatter Dash: A rougher finish often found on external walls of older homes. It’s highly durable and adds character.

Matching Service to Project: Why It Matters

The Right Technique for the Right Job

Choosing the right plastering technique isn’t just about aesthetics — it’s about performance. For example, skimming might be perfect for an old Federation wall, but if the plaster underneath is damaged or damp, it’s a waste of money. Rendering with the wrong mix can crack within a year, especially in Melbourne’s variable climate, with scorching summers and rainy winters.

Performance Matters More Than Looks

When you hire a plasterer, make sure they understand the Melbourne climate. The wrong plastering technique for the wrong job can lead to issues down the line. If your plasterer uses dry lining in a small terrace in Fitzroy, for example, you might lose a few millimetres of room space, which is crucial in smaller homes.

Managing Your Plastering Project: Key Questions to Ask

Preparation and Substrate Condition

A good plaster job starts with a solid foundation. Ask your plasterer the following questions:

• How will they clean and prime the surface? Will they remove old wallpaper, grease, and dust?
• If the old plaster moves or sounds hollow when tapped, will they remove it first?
• How will they deal with cracks, moisture, and damp?

The Plastering Process: Understanding the Method

Ask about their process and the technique they’ll use:

• How many coats will be applied?
• What smoothing method do they use? A pro should work in thin layers with consistent trowel action.
• How will they let the plaster dry? Ensure they use natural drying methods to avoid cracks.

Cost, Quotes, and Contracts: Protect Yourself

Understanding Factors That Affect the Cost

Plastering is not a one-size-fits-all job. Here are some factors that will impact the cost:

Getting Quotes: Don’t Rely on One

Always get at least three quotes and make sure the plasterer inspects the site in person. I had a client in St Kilda who was quoted cheaply over the phone, but once the plasterer saw the condition of the walls, the price doubled.

Managing Payments and Contracts

Never pay more than 25% upfront. For long-term jobs, agree on progress payments after certain milestones. The final payment should be made only once you’re happy with the finish.

The right plasterer can make or break your renovation. Don’t rush your decision. Take the time to find a plasterer with the right experience, credentials, and reputation to ensure you get the quality finish you deserve.
