Render Cleaning Timperley

Most people don’t really notice the state of their render until it’s too late.

One day it looks fine, the next there’s a patch on the side of the house you can’t stop looking at. Green, red, grey, dull brown, sometimes a bit of all four.

Doesn’t mean the property’s been neglected. It’s what happens over time. Damp and growth set in, and bit by bit, the exterior starts to look off.
Then comes the decision:

Leave it and hope it doesn’t get worse,
Or sort it properly.

This isn’t the kind of job to put off. Longer the marks are left to settle, the deeper they go. Doesn’t take much to ruin the look of a good home or building. And it’s not the sort of thing that shifts with a hose or something from the garden centre. It’s a job that needs a proper approach. Anything else is asking for trouble.

The Problem

The thing is, dirty render doesn’t make you a bad homeowner. It happens to literally everyone.

Exterior Cleaning Pros has been render cleaning in Timperley village and the wider Altrincham and Manchester area for years.

We know what it takes to clean it properly without damaging the surface underneath. That’s the bit most people don’t realise. Render might look tough, but if it’s cleaned the wrong way, it can:

Too much pressure, wrong product, not enough rinse—before you know it, there’s a bigger problem than a bit of green.

More often than not, we’re called in after someone’s had a go and realised it’s not as simple as it looks. Not ideal—but it happens. The truth is, there’s a skill to getting render clean and keeping it that way.

Our job’s to get in, clean the surface thoroughly and evenly, and leave it looking how it should.

No harsh blasting, no patchy results. Doesn’t matter if it’s a single wall at the back of a terrace or a full detached property—every bit gets treated properly. If it’s got marks, streaks, algae, or any sort of staining, we sort it.

What you’ll get is your render brought back to a clean, solid finish. Not sparkling white unless it’s meant to be white, not artificially bleached—just clean, level, and right.

The results can be pretty dramatic.
We cleaned a house on Thorley Lane last month where the owner was convinced their render was beige.
Turned out it was actually white—they’d forgotten what colour it was supposed to be.
That’s how much difference a proper clean makes.

Our Proven Render Cleaning Process

We arranged for our render cleaning specialist to assess the property and develop a tailored cleaning plan. Our goal: to remove the staining, undo the poor work left behind, and return the render to a uniform, like-new appearance.

High-Quality Detergent Pre-Treatment

We began by applying a specialist detergent to break down grease, oil, and airborne pollutants. This step ensures the surface is properly prepared and ready for deep cleaning.

Low-Pressure Steam Cleaning

Using our advanced steam cleaning system, we gently but effectively cleaned the entire rendered area. Unlike high-pressure washing, which can damage render, our method safely lifts grime and biological growth without harming the surface.

Render Cleaning Chemicals – Manufacturer Approved

As manufacturer-approved applicators, we applied our specially formulated render cleaning chemicals to target the red and green algae that had built up over time. These chemicals are designed specifically to kill algae spores at the root, preventing quick regrowth.

Final Steam Rinse

After the treatment, we performed a second round of low-pressure steam cleaning to rinse the surface and reveal a beautifully clean, consistent finish.

The transformation was incredible—the patchy, algae-stained render now looked fresh and uniform. The customer was over the moon, especially knowing the job was done correctly and with care.

Cost

We don’t deal in vague estimates

Most of the render cleaning in Timperley is done by using soft-wash systems or low pressure washing, depending on what the surface needs. We’ve got the equipment and the right kit for awkward spots—high gables, narrow alleyways, extensions boxed in on all sides.

We’ve worked on flats, bungalows, school buildings, end-terrace homes, shops, newer developments with coloured render—you get the idea. It’s second nature to us now. You don’t need to know what product does what or how long it needs to sit—we take care of all that.

What you do need is someone who turns up on time, gets on with it, and clears off without leaving a mess behind. And that’s how we work.

You won’t find us disappearing halfway through a job or changing the quote after we’ve started. We don’t deal in vague estimates. Once we’ve seen the property, we give you a clear price. That covers everything, including the clean-up. If anything’s unclear, we sort it out before we begin.

Our process

Safe, Soft wash render cleaning process

Initial Survey & Patch Test

I will visit, or you can send clear photos on email. I always carry out a small test patch in a discreet area. This shows you the result, and it shows me how your render will react. You see there is no guesswork is involved.

Protection and First Treatment

We cover plants, protect windows and soak surrounding areas. I apply the first biocide treatment to break down the green film, black lichen and red algae. We let it dwell. This does the cleaning, not pressure.

Gentle Rinse & Second Treatment

I rinse with low pressure, at a controlled temperature. For stubborn black spots I apply a second, targeted treatment. You will see the colour return as we work, without any damage to the render surface.

Final Walk-Around and Aftercare

We pack away, rinse paths and leave the site tidy. I will show you the completed work and give you simple advice to keep it looking good. For most homes, a light maintenance wash every 18 months keeps it perfect.

What do you get with me

What I will never do is risk damaging your render.

High-pressure washing forces water into your walls, causing damp. I use a controlled soft-wash method that cleans deeply without the damage.

I hold PA1, PA6 and PA6AW City & Guilds certificates.

Many render cleaners skip this. I don't. It ensures the biocides used are legal, safe, and effective for your specific property type.

I treat your home like my own.

I know inviting a contractor onto your property is a leap of faith. That's why I pride myself on punctuality, tidiness, and respect for your space.

My methods are designed for the North West climate.

Damp and shade encourage algae. My treatment plan accounts for this, ensuring your render stays cleaner for longer despite the weather.

Benefits

People often ask how long the results last.

Truth is, that depends on the surface, the area, and how exposed the walls are. What we can say is: if it’s done properly the first time, you shouldn’t be worrying about it again for years.

And if there’s anything else that might affect it—dodgy guttering, blocked downpipes—we’ll point it out. No hard sell, no pressure, but it’s worth knowing.

We’ve always said render cleaning should be simple: turn up, get the job done, and leave the place looking better than it did. That’s the standard. It shouldn’t feel like a gamble every time you call someone out.

We’re not the cheapest and we’re not trying to be. But we’re solid, and we’re fair.

We’re properly insured, obviously. Seems daft to mention it but you’d be amazed how many cowboys work without insurance. If anything goes wrong (it won’t, but hypothetically), you’re covered. We’ve got all the health and safety certificates too. Point is, we do things properly.

That’s probably why most of our work comes from word of mouth. People call us back when they move. Neighbours ask for a quote after seeing a job we’ve done. And trades who’ve seen our work recommend us to their own customers.

So if your rendered surface is looking tired, marked, or you’re unsure whether it’s even worth cleaning, doesn’t cost anything to get an opinion. And we’ll be honest about what needs doing—and what doesn’t.

FAQ

Render Cleaning FAQ's

Will soft washing damage my K-Rend?

No. This is why you hire a specialist. K-Rend, Weber and other manufacturers advise against pressure washing. My system uses pressure lower than a garden hose. It cleans by killing the growth, not by blasting the surface.

How long will my render stay clean?

In South Manchester, a full soft wash and biocide treatment will typically keep your render clear for three to four years. North facing elevations may need a light top-up sooner. I offer a maintenance plan for this.

Is the chemical safe for my garden and pets?

Yes, when applied by a certified user. I hold PA1 and PA6 qualifications for safe application. I pre-wet all plants, cover sensitive shrubs, and neutralise the area after.

Can you remove the black spots completely?

The small black lichen dots are the hardest part of render cleaning. My treatment kills them at the root. They usually fade completely over two to four weeks after we leave, as the wind and rain clears the dead growth. I will show you this on the test patch.

Do you need scaffolding?

For most two storey homes, no. I use professional water-fed poles and low level access equipment. For three storey townhouses in the city centre or awkward areas, I can arrange a cherry picker and it will be included in your quote.

Is render cleaning worth it compared to repainting?

In the majority of cases, yes — significantly. A professional render clean typically costs a fraction of a full repaint, and on a render in good structural condition the result is comparable in terms of appearance. We can advise honestly on this during the assessment.
