Small cracks in your plaster aren't just unsightly; they can cause much bigger problems down the line. Problems that can end up costing you a lot of money. Get repair tips in this guide, or find out when it's best to hire a handyman.
Handyman ServicesSmall plaster repairs are one of those household jobs that seem minor. Until you live with them every day. Hairline cracks above doors, screw holes from old shelves, dents behind furniture or crumbling plaster around sockets can quietly make a room feel tired and neglected. While they may not look serious at first, poorly repaired plaster can lead to uneven walls, flaking paint and recurring damage if the underlying issue isn’t addressed.
The good news is that most small plaster problems can be fixed quickly and cleanly when they’re done properly. This guide explains the most common types of plaster damage, why quick fixes often fail, and when it makes sense to find a handyman who can carry out repairs that last.
Not all plaster damage is the same, and knowing what you’re dealing with helps determine the right repair approach.
Hairline cracks are common in older homes and newer builds alike. They’re often caused by natural movement, temperature changes or minor settlement. While many are cosmetic, repeated cracking in the same place can point to poor previous repairs or movement that hasn’t been stabilised.
Old shelves, curtain rails and TV brackets leave behind holes that are rarely invisible once removed. Even small screw holes can stand out badly after repainting if they haven’t been properly filled and sanded.
Furniture knocks, door handles and general wear and tear can dent plasterboard or knock chunks out of traditional plaster. These areas need more than surface filler to restore strength and shape.
Areas around windows, doors or damp-prone walls sometimes lose adhesion and begin to crumble. Simply skimming over the surface won’t solve the problem if the plaster underneath has failed.
Plaster repairs are frequently underestimated. Many people assume they’re a quick DIY fix, but the results often tell a different story.
One of the most common mistakes is filling a crack or hole and painting over it the same day. Without proper drying time and preparation, the repair shrinks, cracks or becomes visible again within weeks.
Even when the hole is filled, poorly sanded areas or incorrect materials leave a visible patch once painted. Light catches uneven surfaces far more than people expect.
If a crack keeps returning, there’s usually a reason. Movement, loose plaster or vibration needs addressing before any cosmetic repair will hold.
A professional approach focuses on longevity, not just appearance.
Loose plaster must be removed, edges stabilised and the area cleaned before any filler or plaster is applied. Skipping this step guarantees repeat work later.
Different repairs require different products, from fine surface fillers to bonding plaster and mesh reinforcement. One filler does not suit every job.
Good repairs are built up in layers, allowed to dry fully and sanded flush with surrounding surfaces. This creates a seamless finish that disappears once painted.
A proper plaster repair leaves the surface smooth, stable and ready for paint — without sinking, cracking or flashing through later.
