Render Repair Solutions: How to Fix Cracked and Damaged Render

Cracked, peeling, or damaged render is one of the most common issues we see on Melbourne homes. Not only does it look unsightly, but damaged render can also lead to water infiltration, structural damage, and costly repairs if left untreated.

The most common causes of render damage include: ground movement and settling (causing structural cracks), thermal expansion and contraction (causing hairline cracks), impact damage from objects or weather events, poor original application (incorrect mix ratios, insufficient preparation), and age-related deterioration.

Hairline cracks (less than 1mm wide) are usually cosmetic and can be repaired with a flexible filler and paint. However, larger cracks, bulging, or hollow-sounding render indicate more serious issues that require professional attention.

Professional render repair involves several steps: First, we assess the damage and identify the underlying cause. Then, we remove any loose or damaged render back to a solid substrate. The area is cleaned, prepared, and primed. New render is applied using the same system and technique as the original, and finally, the repair is colour-matched to blend seamlessly with the surrounding surface.

At Probuild Rendering, we specialise in render repairs across Melbourne. Our team can match virtually any existing render colour and texture, ensuring your repair is invisible. We also address the underlying cause of the damage to prevent it from recurring.
