Modern new build house with pristine white rendered walls after professional render cleaning service

Rendered surfaces give homes a smooth, stylish look, but over time, they can suffer from discoloration, algae, and moss buildup. Maintaining clean render is essential for preserving your home’s curb appeal and protecting the surface from long-term damage. If you’re looking to clean your render and bring it back to its original beauty, this guide will show you how to do it yourself. And, if you want a professional finish, Mr Clever Clean is here with render cleaning services that deliver stunning, lasting results.


Why Clean Your Render?

Render is highly susceptible to the effects of weather, pollution, and organic growth. Cleaning your render not only keeps it looking fresh but also helps to extend its lifespan. Here are some of the main benefits of regular render cleaning:

  • Enhanced Appearance: A clean render instantly refreshes the exterior of your home, giving it a bright and well-maintained look.
  • Protection Against Damage: Moss, algae, and pollutants can break down render over time, leading to cracks and deterioration.
  • Improved Health and Safety: Mold and algae growth on render can contribute to damp issues inside the home and create slippery surfaces outside.
  • Property Value: Clean, well-maintained render adds to your home’s curb appeal and value.

DIY Render Cleaning: Step-by-Step Guide

If you decide to clean your render yourself, follow these steps to achieve the best results. Remember, cleaning render can be challenging and requires care to avoid damage.

1. Gather Your Supplies

  • Render cleaner or a solution of water and mild detergent
  • Soft-bristled brush or extendable cleaning brush
  • Garden hose with a sprayer attachment or low-pressure washer
  • Ladder, safety goggles, and gloves

2. Choose a Suitable Day

  • Pick a dry, overcast day for cleaning your render. This prevents the cleaning solution from drying too quickly on the surface and leaving streaks.

3. Prepare the Cleaning Solution

  • If you’re using a commercial render cleaner, follow the manufacturer’s instructions for dilution and application.
  • Alternatively, you can mix a mild detergent with water. Avoid harsh chemicals, as they can damage the render’s finish and nearby plants.

4. Apply the Solution to the Render

  • Using your brush, apply the cleaning solution evenly to the render. Focus on areas with visible stains, algae, or moss buildup.
  • Allow the solution to sit for 10–15 minutes to break down dirt and organic growth.

5. Scrub Gently

  • For more effective cleaning, use a soft-bristled brush to gently scrub the surface, paying attention to any spots with heavy buildup.
  • Avoid using hard brushes or high-pressure washing, as these can damage the render or strip off its protective coatings.

6. Rinse Thoroughly

  • Use a garden hose or low-pressure washer to rinse the render thoroughly, working from the top down to prevent streaking.
  • Be sure to rinse until all cleaning solution has been removed to avoid residue that can attract dirt.

7. Allow to Dry

  • Give the render ample time to dry. This usually takes a few hours, depending on the weather conditions.
