A Finish Worth Doing Right
When you are renovating, it can be tempting to cut costs on finishes, but plastering is one area where quality pays you back. A properly layered plaster finish strengthens walls and ceilings, helping them stand up to everyday wear for decades. It is also easier to maintain than many other finishes because it holds its shape and resists knocks and movement. On top of that, plaster is flexible, letting you achieve clean modern lines or more detailed decorative looks depending on your style. Add in soundproofing where you need it, and the space feels better to live or work in.
If you're planning a remodel or extension, have a look through our gallery to see the kind of transformations we deliver. Reach out when you're ready, and we'll help you choose the right finish for your project.
Frequently Asked Questions
How do plasterers match new plaster to existing walls during a renovation?
Matching is about more than filling a gap. Plasterers check the thickness of existing sheets, the type of cornice or moulding and any current textures or paint build up. They may feather joins wider than usual so the transition disappears once painted. In older homes, extra prep is often needed to stabilise brittle areas before new plaster goes on. The goal is a finish that looks continuous, not like a patch.
What hidden issues can affect plastering on extensions or remodels?
Renovation plastering can be slowed down by uneven framing, movement cracks, moisture damage or older materials that are no longer straight. Ceilings may sag slightly over time, so new work has to be set to the right line to avoid a visible step. Older walls can also hide previous poor repairs that need fixing before fresh plastering starts. If these issues are spotted early, the plastering plan can be adjusted without blowing out the schedule. It is normal for renos to need a bit more problem solving than new builds.
When is soundproof plastering worth including in a renovation?
Soundproofing is most useful when layouts change or rooms sit back to back, like bedrooms near living areas or home offices next to kitchens. Adding sound rated plasterboard or acoustic systems during a reno is easier and cheaper than retrofitting later. It can noticeably reduce noise transfer, especially in two storey homes and open plan extensions. Homeowners often choose it for media rooms, nurseries or shared walls. It is a practical upgrade that improves comfort straight away.
