Render Cleaning Techniques for Plymouth Exterior Walls

Maintaining the appearance and longevity of your home’s rendered surfaces can be straightforward when you choose the right techniques for cleaning. Render, the external plaster that covers many homes, can accumulate dirt, stains, and algae over time, leading to a tired and less desirable look. It’s therefore essential to carry out regular maintenance to keep your home looking its best. One of the popular render cleaning techniques for Plymouth is Softwashing, which uses low-pressure water and specialised cleaning solutions to remove unwanted grime without damaging the delicate surface of the render.

A good Plymouth render cleaning company will have expertise in Softwashing, along with steam cleaning and manual scrubbing techniques, so bear these in mind when you make your choice of tradesman.

Understanding the nature of the stains on your render is key to choosing the correct render cleaning approach. For more stubborn stains, such as those caused by atmospheric pollutants or organic growth, you might require a more intensive render cleaning method. Whichever technique you choose, it’s important to ensure that it will not deteriorate the render’s integrity or appearance. Consistent maintenance will help in preventing the build-up of dirt and the proliferation of unsightly stains, keeping your render clean and your home’s exterior aesthetically pleasing.

Understanding Render and Its Common Issues

Before you tackle cleaning your render, it’s important to understand the materials you’re working with and the common issues that can arise over time. By being informed, you can address problems effectively and maintain the aesthetic integrity of your building.

Types of Render

Cement Render: This traditional mix typically consists of sand, cement, and lime. Cement render is known for its durability but can be susceptible to cracking over time due to its rigidity.

Acrylic Render: This is a more flexible type of render that includes acrylic resins. Acrylic render is less prone to cracking and can be pre-coloured.

Monocouche Render: A through-coloured render, which means it won’t need painting. It is breathable and water-resistant, reducing the risk of damp issues.

Silicone & Silicate Renders: These renders are highly breathable and offer excellent water-repelling properties, making them less likely to encourage organic growths like algae.

Common Render Problems

  • Stains and Discolouration: Various factors, like weather conditions and pollution, can lead to unsightly staining on your render.
  • Algae and Moss: These organic growths are common in damp, shaded areas and can cause green, red, or black discoloration.
  • Dirt Build-up: Render can accumulate dirt over time, detracting from the building’s appearance.
  • Growth of Vegetation: Roots from plants and vegetation can cause physical damage and cracks.
  • Cracks: Structural movement or improper application can result in rendering cracks.
  • Damage: Physical impact or environmental wear and tear can cause chunks to break away.

By being mindful of these issues and choosing the correct render cleaning techniques, you can preserve the quality and appearance of your render for years to come.

Fundamentals of Render Cleaning

Before you choose a Plymouth render cleaning company to freshen up your home’s exterior, understanding the basics of render cleaning is crucial. It’s about using the right approach to enhance your property’s look without causing any harm.

Assessing Render Condition

Firstly, inspect the condition of your render. Look for cracks, stains, algae growth, and other signs of wear and tear. This examination determines the extent of cleaning needed and identifies areas that require particular attention. Take note of the render’s age and previous maintenance history, as these factors influence your choice of cleaning method.

Choosing the Correct Cleaning Method

Pressure washing can be effective but requires a careful approach. Use a low-pressure setting and avoid aiming directly at cracks or joins to prevent damage. Conversely, soft washing is a gentler option using low-pressure water combined with a specialised cleaning solution to lift dirt and organisms like algae without risking the render’s integrity.

For areas needing more focused cleaning, a chemical cleaning solution may be necessary. Opt for a gentle, non-abrasive product that won’t compromise the render’s surface.

Another technique to consider is render steam cleaning for Plymouth properties. This is an eco-friendly technique

By approaching render cleaning thoughtfully and selecting suitable techniques, you’ll achieve a pleasing aesthetic without compromising the render’s longevity.

Effective Cleaning Techniques for Render

When considering cleaning techniques for the exterior render on your property, the goal is to achieve a clean, attractive finish without causing any damage. Here’s a rundown of methods you can use to restore the appearance of your rendered walls.

Pressure Washing: Pros and Cons


  • Efficient: It’s a fast way to clean large areas.
  • Water-based: Only water is used, making it an eco-friendly option.


  • Potential Damage: Too high pressure can erode the render.

Softwashing Explained

Softwashing is a gentle alternative to pressure washing. It combines low-pressure water with a cleaning solution to effectively remove grime.

This method minimises the risk of damage while still being effective against dirt and pollutants.

Chemical Cleaning Methods

Chemical cleaners can target specific kinds of dirt and staining.

Manual Cleaning and Brushing

For small areas or delicate render, manual cleaning with a brush can be effective. This method offers control over the scrubbing force, making it safer for the render.

Steam Cleaning

High temperature and low-pressure steam cleaning in Plymouth effectively remove dirt and kill biological growths.

Key Points:

  • Non-abrasive: No harsh scrubbing required.
  • Sanitising: High temperatures kill algae and fungus.

Steam cleaning is a good option for dealing with stubborn stains and sanitising surfaces. Choosing a Plymouth render cleaning company that has expertise in steam cleaning can be an excellent choice.

Render Protection and Preservation

Proper maintenance not only enhances the appearance of your rendered walls but also extends their lifespan and integrity. The application of sealants and the adoption of preventive measures are key to minimising future damage to your render.

Sealants and Protective Coatings

To guard the surface of your render, consider applying a protective coating. These coatings are designed to protect against a variety of external factors, such as water ingress, which can cause cracks and erosion over time. When selecting a sealant, make sure it allows your walls to “breathe”, maintaining their durability without trapping moisture.

  • Water-Repellent Sealants: Provide a barrier against rain and moisture.
  • Breathable Sealants: Allow trapped moisture to escape, preventing internal issues like mould growth.
  • Anti-Graffiti Coatings: Make cleaning easier should your walls be vandalised.

Preventative Measures for Minimising Damage

Taking preventive actions can vastly reduce the need for repairs and preserve your render’s integrity.

  • Regularly inspect your walls for cracks or signs of damage.
  • Gently clean your walls with appropriate methods—avoid high-pressure washing to prevent damage.
  • Trim back any vegetation that could grow against render surfaces, which might lead to moisture retention and possible damage.
  • Ensure good air circulation and prevent excessive moisture by addressing issues such as poor guttering or downpipe leaks promptly.

Cost and Value of Render Cleaning

When considering render cleaning, you’re looking at both the immediate costs for the service and the long-term value it adds to your home. It’s not just about the aesthetic uplift; regular maintenance can prevent expensive repairs down the line.

Evaluating Cleaning Costs

The cost of professional render cleaning can vary based on factors like the size of your home and the extent of the cleaning required. For an average 2-bedroom terraced house, prices might range from £300 to £400. A larger 3-bedroom semi might set you back between £500 and £600. It’s worth noting that these are just estimates and actual prices can vary depending on the cleaner you choose, the condition of your render, and your location in the UK.

  • 2-bedroom terrace house: £300 – £400
  • 3-bedroom semi-detached house: £500 – £600

Remember, trying to save costs by attempting DIY could lead to damage, ultimately pushing up costs with repair bills.

Improving Curb Appeal and Property Value

Investing in professional render cleaning can enhance your home’s curb appeal significantly. A clean facade not only makes your home stand out but may also increase its market value. As a homeowner, the cleanliness of your property has a direct impact on first impressions and, potentially, on how much you can sell it for in the future.

  • Curb Appeal: Enhanced attractiveness of your property from the street.
  • Property Value: Potential increase in sale price due to improved appearance and upkeep.

By maintaining a clean exterior, you’re not just keeping up appearances, but you’re also investing in the longevity and value of your property.

DIY Render Cleaning vs Professional Services

Professional services are advisable when:

  • Complexity: The building is tall or the render is heavily soiled.
  • Safety: Access issues exist that require specific equipment like scaffolding.
  • Quality: You’re seeking a deep clean without risking damage to the render.

Professionals come equipped with the right tools and expertise. They can provide tailored solutions, including biocide treatments, that last longer and protect the render. Plus, risking personal injury or property damage is never worth the potential cost savings of DIY attempts.
