Patio Cleaningin Reading
Reading's Victorian terraces, inter-war suburbs and newer estates give it every size of patio, from walled yards to wide suburban terraces. We plan access, protect the brickwork around the paving and clean each surface to suit it.
- Access planned at the visit
- Brick boundary walls protected
- Chiltern EverGuard™ applied
Our approach
Small yards and wide terraces need different plans
A narrow walled yard behind a terrace and a broad terrace behind a suburban semi share little beyond being paved. One is shaded by brick on three sides and may be reached through the house; the other is open and reached by a side gate. At a free site visit we look at the paving, how we will reach it and what is growing on it.
Reading homes
Victorian streets, inter-war suburbs and two rivers
Reading expanded rapidly in the Victorian period, and street after street of red and patterned brick terraces still define much of the town, many of them within its conservation areas. Edwardian homes, inter-war suburbs and modern developments fill out the rest, out towards Caversham, Tilehurst and Earley.
The town sits where the Kennet meets the Thames, and gardens close to either river, or under mature trees, dry slowly. In a terrace yard, high boundary walls add their own shade, so the paving at their foot can stay damp for most of the day, which is exactly where algae and black spot settle.
Getting there
Reaching a patio with no side access
Many terraced houses have no side gate, and some rear gardens open only onto a shared alley. That changes how equipment, hoses and water reach the patio, and it is the first thing we check at the site visit rather than something to discover on the day.
Where hoses must pass through the house, floors and doorways are protected and runs are kept tidy. Where there is rear access, we confirm it is clear and usable before the clean is booked.
Brick boundaries
Cleaning beside old brick walls
A walled yard puts the paving right against brickwork that may be well over a century old, with soft mortar and, in places, the patterned brick the town is known for. Uncontrolled spray along that base can wash out pointing and mark the wall.
We clean the paving up to the wall with the jet angled away from the masonry and the pressure set for both surfaces. The green band that forms where wall meets paving is lifted without turning the clean into an attack on the wall.
Black spot
Lichen marks on sandstone and limestone
Black spot is a living lichen that grows within the pores of natural stone, and in shaded yards it can spread across most of a patio. Pressure alone takes the top off and leaves the growth behind.
Our treatment works in two stages: a controlled combination of pressure and specialist application deals with the visible marks, then the Chiltern EverGuard™ Treatment works into the stone to target the live growth at its source. Heavily marked paving can take a second visit to clear.
Before a sale
Getting a garden ready for photographs and viewings
A green or blackened patio can make an otherwise well-kept garden look neglected in listing photographs. A professional clean ahead of a sale restores the paving's colour and definition and makes the space feel usable again.
We are clear at the site visit about what will lift and what will remain, so you are not relying on a result the paving cannot give. Allow the paving to dry fully after the clean before the photographs are taken.
Step by step
How a patio clean runs from start to finish
The stages are the same for a terrace yard and a large suburban patio. What changes is the access, the method and the effort each stage needs.
- 01
Site visit and access check
We identify the paving, its joints and the growth on it, and confirm how equipment and water will reach the garden, whether by side gate, rear alley or through the house.
- 02
Preparing the space
Furniture and pots are moved where practical, floors and doorways along any hose route are protected, and walls and planting are considered before cleaning starts.
- 03
Cleaning at the right pressure
The paving is cleaned at the lowest effective pressure for its material, with the jet kept off old brickwork and away from joints that are already weak.
- 04
Black spot and joint care
Lichen receives a specialist application, and washed-out joints are re-sanded where needed so the slabs stay stable and the patio is firm underfoot.
- 05
Rinse, review and Chiltern EverGuard™
After a final rinse and review, the Chiltern EverGuard™ Treatment is applied to slow regrowth, and anything that needs a separate repair is pointed out.
Before you book
What to expect, and what to leave to a builder
Cleaning restores colour, removes growth and makes paving safer underfoot. It does not rebuild what has failed, and in a shaded yard growth will return sooner than on an open terrace.
- Loose or cracked slabs need relaying
- Mortar washed from walls long ago needs repointing
- Deep historic stains may lighten without disappearing
Why us
Why it is worth asking us to look

Paving is cleaned right up to boundary walls without driving water into soft mortar or marking patterned brick.
Chiltern EverGuard™ applied
Every cleaned patio receives the treatment. Protection typically lasts between 12 and 24 months, depending on shade, moisture, the surface and upkeep.
Fully insured
Our operatives are fully insured, and we leave floors, doorways and gardens as we found them, apart from the cleaner patio.

Questions
Patio Cleaning in Reading: your questions
Can you clean a patio if we have no side access?
Yes. We check access at the site visit. Where hoses and equipment must come through the house, floors and doorways along the route are protected; where there is a rear alley, we confirm it is clear before booking.
Will cleaning damage the brick wall beside the patio?
No, provided the jet is controlled. We angle it away from the masonry and set the pressure for both the paving and the wall, so soft mortar and older brick are not washed out or marked.
Can you remove black spot from a shaded yard?
Usually, yes. Black spot is a lichen, so it is treated with a specialist application and the Chiltern EverGuard™ Treatment rather than with extra pressure. Heavily marked paving can need a second visit, and shaded yards may see it return sooner.
Do I need to move garden furniture before you arrive?
Only where it is practical. Clearing pots, furniture and small items lets us clean the full area, including the footprints under them. If something is heavy or awkward, tell us when you book and we will plan for it.
Is it worth cleaning the patio before selling?
Often, yes. Paving that has gone green or black can make a garden look neglected in photographs, and a clean restores its colour and definition. We will tell you at the site visit what will lift and what may remain.
How long will the Chiltern EverGuard™ Treatment last in a walled garden?
Typically between 12 and 24 months. A walled, shaded yard tends to sit towards the shorter end because the paving stays damp, while an open suburban terrace usually holds up for longer.
