Plasterer Brisbane: what to know before renovating an older home

2 days ago

6 min read

This guide is for Brisbane homeowners renovating a house built before the 1990s who want to know what to check before booking a plasterer. Type "plasterer Brisbane" into Google and you get pages of results. Very few of them talk about the problems older homes throw up.

We're MLR Plastering & Interiors, and we've been finishing walls and ceilings across Brisbane and South East Queensland for over 15 years. Older houses are where the hard calls get made. Picking the right plasterer in Brisbane for that kind of job comes down to one thing: who spots the problems before they cut into a wall.

What's usually behind the walls of an older Brisbane home

Brisbane's older housing is a mixed bag. A 1920s Queenslander, a 1960s brick lowset and a 1970s fibro house each need different handling, and plenty of homes have had two or three renovations stacked on top of each other.

Here's what we regularly find once the old linings start coming off:

Fibrous plaster ceilings held up by plaster wads or nails that have let go over the years, leaving a ceiling that dips in the middle of the room.
Hard set plaster over brick in post-war homes. It's solid, but it cracks along stress lines above doors and windows.
Fibro sheeting on walls, eaves and old wet areas, which may contain asbestos.
VJ timber walls in Queenslanders, where owners want plasterboard lining and the walls are rarely straight enough to sheet over directly.
Old water stains from leaks fixed years ago, with soft or crumbling plaster hiding behind the paint.

None of this is a reason to put off the renovation. It just means the quote should come after someone has stood in the room and looked, not after a two-minute phone call.

Does your older home have asbestos?

If your home was built or renovated before 1990, treat any fibro sheeting as possible asbestos until it has been tested. Asbestos was banned in Australian building products in 1990, with a total ban from 2003. Fibro walls, eaves and older wet area linings are the usual places it turns up.

For more detail, the Queensland Building and Construction Commission (external source) has a page on asbestos safety when renovating an older home. It covers where it tends to hide and how to get a sample tested.

A plasterer should raise this before quoting, not halfway through the job. If they don't bring it up, that tells you something. Book a licensed assessor, get the result back, then plan the plastering around it. A test costs far less than cleaning up a house full of fibres.

How do I check a Brisbane plasterer is licensed?

Search the plasterer's name or licence number on the QBCC licensee register. The name on the licence should match the business you're dealing with, and the licence class should cover wall and ceiling lining work. If someone can't give you a licence number on the spot, keep looking.

The Queensland Building and Construction Commission (external source) also explains how to find and check a licensed contractor, including what a licence history shows. Our QBCC licence number is 15533475. Look it up before you book us, we'd rather you did.

Matching old textures so the repair disappears

The worst result on an older home is a repair you can spot from across the room. New plasterboard set dead flat sits next to a ceiling that's been painted eight times and dropped a few millimetres. The line between them shows the moment the afternoon light hits it.

Good renovation and restoration plastering starts with reading the existing surface. On older jobs we look at:

The finish, whether it's a smooth hard set, a sand finish or something hand-textured decades ago.
The cornice profile. Plenty of older designs aren't stocked anymore, so they need sourcing or a very careful join.
How flat the existing ceiling really is, so new sheets can be feathered in instead of leaving a step.
How much paint is already on the wall, because heavy build-up changes how a patch reads once it's painted.

We match existing textures and finishes on renovation work so the new section blends in. Once the painter has been through, you shouldn't be able to point to where the old wall stops and the new one starts.

Should you patch or replace an old ceiling?

Patch it if the ceiling is firmly fixed and the damage is limited to cracks, small holes or a stain. Replace it if it's sagging, soft to the touch or pulling away from the joists. A sagging fibrous plaster ceiling can come down with little warning, so don't sit on that one.

Signs a ceiling has gone past patching:

A visible belly or dip in the middle of the room.
Nails popping through the paint in a straight line along a joist.
Cracks that come back a few months after they've been filled.
Plaster that crumbles under your thumb near an old leak stain.

Questions to ask before you sign a plastering quote

A quote tells you the price. These questions tell you how the job will actually go:

What's your QBCC licence number?
Has anything here been tested for asbestos, or do I need to organise that first?
Are you patching or replacing, and what made you decide that?
How will you match the existing finish and cornices?
How will you protect floors and furniture from sanding dust?
Will the walls be paint-ready when you leave?
What's the timeline, and how many visits will it take?

Anyone worth hiring will answer these without hesitating. When the answers are vague, the workmanship tends to follow.

Plasterer Brisbane FAQs for older homes

Can an old fibrous plaster ceiling be repaired instead of replaced?

Yes, as long as it's still firmly fixed. Cracked joins, small holes and old stains can be cut out and patched to match the surrounding ceiling. Once a ceiling is sagging or soft, replacement is the safer call.

How long does plastering take in an older home?

Most patch repairs take two or three short visits, because each coat of jointing compound has to dry before the next one goes on. Bigger renovation jobs get a clear timeline from us before any work starts, so you can line up the painter.

Do I need an asbestos test before plastering starts?

Yes, if your home was built or renovated before 1990 and the job touches fibro sheeting. Have a licensed assessor test it before anyone cuts or sands it.

Can you match the texture on my existing walls?

Yes. We match existing textures and finishes on renovation jobs, so the repaired section sits in with the rest of the room once it's painted.

Do you handle insurance plaster repairs on older homes?

Yes. We carry out insurance plaster repairs for water, storm and impact damage, and we can deal with your insurer directly where needed.

Publishing notes

Cannibalisation: the homepage and /plasterer-brisbane/ already target "plasterer brisbane". Keep this post on the older-home angle and let it pass authority to the homepage via the intro link. Do not retitle it as a general plasterer page.

Brief conflict: the brief caps internal links at 3, the DCB SEO standard asks for 8 to 10. Brief followed. Add more only if Derek approves.

Brief goal mentions event bookings and chapter visits. That line looks copied from another client brief. CTA uses MLR's real actions (call and quote form).
