Choosing the right render cleaning company matters.
Your home’s exterior is one of its biggest investments, and poor cleaning methods can cause permanent damage to render. Before you pick up the phone, here are five things every homeowner should know before hiring a render cleaning company.
1. Not All Cleaning Methods Are Safe for Render
One of the biggest mistakes homeowners make is hiring a company that uses high-pressure washing on render. While this works for driveways or brickwork, it can crack render, strip coatings, and shorten its lifespan.
Instead, look for companies that offer:
-
Soft Washing – a low-pressure cleaning method that kills algae and mould at the root.
-
Steam Cleaning – gentle, effective, and safe for delicate render surfaces.
At Leeksons Render Cleaning, we specialise in both techniques to ensure your render is cleaned without risk.
2. Experience With Render Cleaning Is Essential
Render isn’t the same as stone, brick, or cladding—it’s a delicate surface that needs the right care. Make sure the company you choose has proven experience with different render types, including:
-
K-Rend
-
Monocouche
-
Sand & cement render
-
Painted render
Hiring a general “pressure washing” company without render expertise can be a costly mistake.
3. Ask About Biocide Treatments
Cleaning alone isn’t enough. If a company doesn’t use a biocide treatment, algae and moss will quickly return. Biocides kill spores and protect your render for months, sometimes years, after cleaning.
A reputable company will always include a professional biocide treatment as part of the process.
4. Check Insurance and Guarantees
Render cleaning involves ladders, equipment, and chemicals—so insurance is a must. Always ask:
-
Do you have public liability insurance?
-
Do you guarantee your work?
This protects both you and your property if anything goes wrong.
5. Look for Reviews and Local Reputation
Finally, don’t just take their word for it—check reviews on Google, Trustpilot, or Facebook. A reliable render cleaning company will have:
-
Positive reviews and testimonials
-
Before and after photos
-
Local case studies
This helps you feel confident you’re hiring professionals who care about quality.
FAQs About Hiring a Render Cleaning Company
1. How much does render cleaning cost in the UK?
The price depends on the size of your home, type of render, and severity of algae. On average, expect £300–£900 for a standard house, but always get a tailored quote.
2. How long does render cleaning last?
With soft washing and a chemical treatment, results typically last 3-5 years. Shaded or damp properties may need more frequent cleaning.
3. Can’t I just pressure wash render myself?
No. DIY jet washing can crack render and cause long-term damage. Soft washing is the safer choice.
4. Will render cleaning damage my home?
Not if done correctly. Professional soft washing is designed to clean render safely without removing coatings or damaging the surface.
5. Do I need planning permission for render cleaning?
No—render cleaning is considered maintenance, not building work. However, listed buildings may need extra care or approval for treatments.

Hiring the right render cleaning company makes all the difference between a long-lasting, safe clean and potential damage to your home. Always check their methods, experience, insurance, and reviews before you decide.
