Rendered walls are designed to protect your home from the British weather, but even the best render systems require periodic care. Lancashire properties face constant rain, damp air and temperature changes, which means regular maintenance helps extend the lifespan of your render and prevents issues such as cracking, staining and water ingress.

How Often Should You Check Your Render?

• Every 6 to 12 months carry out a simple visual inspection. Look for hairline cracks, algae growth and patchy discolouration, especially on north facing walls.
• Every 2 to 3 years gently wash the render with warm water or a low pressure rinse to remove dirt, grime and green algae build up.
• Every 5 to 10 years consider a professional assessment to ensure the system is still watertight and properly bonded.

Why Maintenance Matters in Lancashire

Homes in Preston, Chorley, Blackburn and the wider North West experience harsh winters and consistent moisture. Without upkeep, small issues can quickly escalate into costly repairs. Silicone render requires less maintenance, but even modern systems benefit from occasional cleaning and inspection.

When to Call a Professional

• Visible cracking even small cracks can allow moisture behind the surface.
• Loose or hollow sounding areas which indicate failed adhesion.
• Heavy staining or algae that does not wash off easily.
• Previous poor workmanship from older or low quality render systems.

With routine care, your render can last decades and keep your home looking clean and protected. Regular checks help ensure durability while preventing unnecessary repair costs.
