Patio Cleaning Altrincham
Your patio is supposed to be the usable bit of your garden – where you put the BBQ, outdoor furniture, maybe a few pots if you’re into that sort of thing.
But over time, it stops being usable. It gets slippery, unevenly coloured, patchy in places, and frankly, looks like a neglected corner of a park.
In Altrincham, this happens faster than you’d think. Our climate – with its generous rainfall, shade from trees (if you’ve got them), and general foot traffic means your patio turns into a biological experiment.
Moss, algae, lichen – they all thrive in this climate. The result? A surface that’s 90% plant life, 10% original stone (or concrete, or whatever it’s made of). Nobody wants to host a garden party on a surface that looks like a damp forest floor.

The Problem
Why You Can’t Just Hose It Off
You can’t just sweep it away or rinse it with a hose. This stuff has established roots. Dust and pollution particles don’t just make your patio look grey – they bond chemically with the surface material over time.
On brick or concrete, this creates an ugly, rough texture that can’t be swept or hosed away. It’s not dirt; it’s a chemical reaction that’s altered the top layer of your material. This isn’t aesthetic; it’s degradation. The rougher the surface, the more it holds onto future dirt, the faster it deteriorates.
Leaf litter and bird droppings aren’t just messy – they’re acidic. When they break down, they lower the local pH around your paving. This isn’t a problem on granite (which is inert), but most patios in Altrincham are built from more reactive materials. Acidic conditions accelerate weathering of concrete, erode mortar, and stain natural stone irreversibly.
So what does this mean for you? It means that every year, without maintenance, your patio loses integrity. The joints widen, the slabs destabilise, the colours fade or darken unevenly.
You might get away with it for five-six years. By year seven, you’re looking at £3,000-£5,000 of remedial work (new slabs, re-laying, drainage fixes) that could’ve been £300-£500 of regular cleaning over that same period.
Re-laying a typical 20m² patio in Altrincham can cost around £1200-£2400. Our service extends that lifespan by 5-10 years, for a fraction of the cost.
The average Altrincham homeowner deals with this in one of three ways
- They ignore it. The patio gets progressively grim until it’s basically unusable. You stop having friends over, stop putting the bins out there because you don’t want to walk on the slippery bits, and eventually it just becomes “that part of the garden we pretend doesn’t exist”.
- They try to clean it themselves. You buy a stiff brush, some bleach from B&Q, and spend a Saturday morning on your hands and knees scrubbing. Result? You get tired, your back hurts, and it still looks pretty awful. Bleach isn’t magic – it kills some stuff, but the root cause (embedded dirt, organic growth) stays put.
- You’re left with a half-clean patio that looks like you’ve made an effort, but really haven’t solved the problem. They call patio pressure washing and cleaning company in Altrincham. At Exterior Cleaning Pros, we’ve seen and worked on enough patios across South Manchester and North Cheshire to know exactly what the problem is, and exactly how to fix it.

Trained, Insured, and Respectful
Our technicians are uniformed, trained, and fully insured. We turn up when we say we will, get the job done without cutting corners, and leave the space cleaner than we found it — no half-finished work, no mess left behind.
Each job begins with a proper assessment of the surface and its condition. Is the staining organic or chemical? Is there existing sealant? Are there signs of movement in the paving or broken joints? Once we’ve identified what the surface actually needs, we clean accordingly.
Where black spot and lichen are present, we don’t rely on water pressure alone. We use targeted treatments with the correct dwell time to break them down before they’re removed. This prevents unnecessary erosion from over-washing and gives longer-lasting results.
When a patio is cleaned properly — not rushed through, not overblown with pressure — it doesn’t need constant attention. One deep clean, done right, puts the surface in a maintainable state. From there, simple upkeep keeps it looking sharp without needing constant intervention.
Exterior Cleaning Pros Difference
We Solve the Root Problem, Not Just the Appearance
Most patio cleaning services in Altrincham offer a ‘pressure wash and go’. That’s because it’s quick, it’s visual, and it’s cheap for them to deliver. What they don’t tell you is that jet washing alone makes the problem worse long-term.
Here’s why: When you blast high-pressure water (typically 150-200 bar) at your patio, you do dislodge surface dirt – great.
But you also:
- Drive water into those existing micro-cracks, accelerating freeze-thaw damage
- Strip away the top sealant (if your patio was ever treated properly)
- Compact moss/algae deeper into the surface pores (it’ll come back faster next time)
Our approach is different because we actually understand what’s going on beneath the surface, not quick fixes. We start by identifying what your patio is actually made of (not all stone is the same; not all concrete is either).
Then we select the right pre-treatment (not just water; often a pH-neutral biocide that kills organic growth before we touch it with water). Only then do we use a low-pressure, hot water extraction system that lifts dirt without forcing anything into the surface. We don’t stop there.
After cleaning, we offer (not insist on, offer) a breathable, UV-stable sealant tailored to your patio material. This isn’t to make it look ‘wet’ or ‘new’ – it’s to slow down the entire deterioration process we talked about earlier. A properly sealed patio sheds water, reduces organic growth by 70-80%, and makes future cleanings 50% faster (and cheaper).

Fixing the Mistakes of Previous Work
Some patios we clean have been previously sealed using the wrong product. This often results in patchy discolouration, peeling, or uneven wear.
These coatings need to be properly stripped before any new treatment is applied — not simply cleaned over. We identify these issues before starting and advise on the correct next steps.
In some cases, the best action is to clean and leave the surface unsealed. In others, resealing with the right product improves performance. Either way, we don’t push unnecessary treatments or cover up problems.
Unlike most setups that rely on rented gear or domestic pressure washers, we’ve invested in industrial-grade systems that deliver consistent, surface-safe results.

FAQ
Patio Cleaning FAQ's
Will jet washing damage my concrete?
No. Damage is caused by holding a zero-degree nozzle too close to the surface. I use the correct fan, the correct distance and a surface cleaner that spreads the pressure evenly.
Do you make a mess with slurry?
No. I control water flow, I contain run-off from commercial sites, and I rinse all adjacent areas before I leave. On domestic jobs I protect lawns and borders.
How long will it stay clean?
On a domestic path, with the biocide applied, you can expect eighteen months to two years before significant regrowth. On a busy commercial yard with heavy traffic, an annual clean maintains standards.
Can you work at weekends?
Yes. I work at your convenience can I can work overnight cleans for commercial clients across Manchester and Cheshire.
Do you remove oil stains and chewing gum?
Yes. I use a hot water system with a specialist degreaser for oil. For chewing gum I use steam at 150 degrees. I will test a small area first and show you the expected result.
