The Service
What pressure washing is actually for
Outside surfaces in this climate don't just get dirty; they grow. Damp, shade and mild winters give algae, moss and lichen everything they need, and within a couple of seasons a light path turns green-black, a rendered wall streaks, and decking becomes genuinely dangerous underfoot. That's organic growth bonded to the surface, and no amount of sweeping shifts it.
Professional pressure washing removes it properly: the growth, the ingrained dirt and the black weathering film, taken back to the actual colour of the material. The critical part is control. Pressure that's ideal for a concrete yard will scar soft brick, strip render, splinter decking and cut lines into paving. Matching pressure, nozzle, distance and technique to the surface is the difference between restoration and expensive damage.
We pressure wash paths, steps, walls, decking, yards, hard standing, garden walls and general exterior surfaces across North London and Hertfordshire, for homeowners, landlords and businesses alike.
Who it's for
- Homeowners whose paths and steps have gone green and slippery
- Anyone with decking that's become a slip hazard in wet weather
- Landlords and agents preparing a property for let or sale
- Businesses responsible for safe access across their frontage
- Households booking an exterior refresh before summer or before Christmas
When it's needed
- Green or black staining across paths, steps and paving
- Slippery surfaces underfoot after rain
- Streaked walls, render or brickwork
- Decking that's lost its colour and grip
- Before selling, letting, or an outdoor event
Why professional help matters
Domestic pressure washers cause a lot of the damage we're asked to look at: zebra-striped paving from an uneven pass, render blown off a wall, decking with the soft grain washed out, and pointing forced out from between bricks.
Water goes where you point it, too. High pressure aimed at the wrong angle drives water under thresholds, behind render, into airbricks and through vents. Knowing where not to point the lance matters as much as knowing how to use it.
What Happens If You Leave It
Green surfaces are a safety problem before they're a cosmetic one
People usually book pressure washing because the outside looks tired. The more serious issue is grip: algae on a wet path or deck is genuinely slippery, and it's most dangerous exactly where people walk most.
Slips and falls
Algae-covered paving and decking become skating rinks after rain. Steps and entrance paths are the highest-risk spots, and the people most likely to fall are the ones least able to take it.
Growth eats into the surface
Moss and lichen root into the pores of concrete, stone and timber. The longer they're left, the more they open the surface up and the harder they are to remove cleanly.
Water sits where it shouldn't
Moss holds moisture against the material. On timber that means rot; on masonry it means constant damp and accelerated frost damage in winter.
Frost damage in winter
Water trapped in a saturated, organically clogged surface expands when it freezes, spalling concrete and cracking paving.
The property looks neglected
The approach to a building sets the impression of everything behind it. Green paths and streaked walls read as neglect to buyers, tenants and customers.
Cleaning becomes replacement
Left long enough, timber rots and paving pits. At that point the cost stops being a clean and starts being a rebuild.
The mistakes that cost people the most
- Using maximum pressure on every surface regardless of material.
- Holding the lance too close, leaving permanent stripes and gouges.
- Pressure washing soft brick, old render or lime pointing at high pressure.
- Blasting decking across the grain and splintering the boards.
- Driving water under doors, behind render or into airbricks.
- Washing debris straight into drains and gullies and blocking them.
Our Process
The step-by-step system we use on every job
Survey and surface assessment
We look at the materials involved, their condition, pointing and joints, nearby drainage, plants and any vulnerable details, then agree the scope and a clear price with you before starting.
Preparation and protection
The area is cleared, loose debris removed, and doors, airbricks, planting and adjacent surfaces protected. Access and drainage routes are planned so water goes where we intend.
Pre-treatment where needed
Heavy moss, lichen and stubborn organic growth are treated first so they can be lifted with less pressure: less force on the surface, better result.
Controlled washing
Pressure, nozzle and distance are matched to each material and worked in consistent overlapping passes, which is what avoids the striping that DIY jobs are famous for.
Rinse and clear down
The surface is rinsed evenly, debris is cleared rather than pushed into gullies, and surrounding areas are left tidy.
Final walkaround and guarantee
We walk the area with you, explain anything that is permanent staining rather than dirt, and back the work with our service guarantee.
What You Get
Specific results, not vague promises
Safer underfoot
Removing algae restores grip on paths, steps and decking: the single most valuable outcome of the job.
The real colour back
Surfaces come back to the material's own colour rather than a weathered grey-green film.
No DIY damage
Pressure matched to material means no striping, no blown render, no splintered decking and no forced-out pointing.
Longer surface life
Getting growth and trapped moisture off slows rot, frost damage and pitting: pushing replacement years down the line.
Instant kerb appeal
The approach to the property is what people judge first, and it's the cheapest part of the exterior to transform.
Insured and guaranteed
£5m public liability cover, a service guarantee on every job, and the same father-and-son team on site.
In Detail
Surfaces, materials and how the approach changes
Pressure washing is one name for a lot of very different jobs. What we do to a concrete yard is not what we do to old brick or softwood decking.
Surfaces we clean
- Paths, footways and garden steps
- Concrete yards, hard standing and parking areas
- Decking and timber steps
- Garden and boundary walls, brickwork and render
- Bin stores, side returns and access alleys
- Commercial frontages, forecourts and service yards
Materials and their limits
- Concrete and concrete flags: tolerant of higher pressure but easy to stripe if passes are uneven.
- Natural stone: variable hardness; pressure kept lower and tested first.
- Brick and pointing: soft old brick and lime mortar need low pressure or they lose their face and joints.
- Render and painted masonry: cleaned carefully; high pressure removes coating along with the dirt.
- Timber decking: washed with the grain at controlled pressure to avoid raising and splintering the surface.
Situations we're called out for
- Slippery entrance paths and steps, especially at properties with elderly residents
- Decking that has turned green and lost its grip
- Streaked or algae-marked walls on shaded elevations
- End-of-tenancy and pre-sale exterior refreshes
- Businesses keeping frontages and access routes safe and presentable
- Post-building-work cleaning of dust, splashes and general mess
Residential vs commercial
At home, pressure washing is usually about safety and appearance: the path to the front door, the back patio, the decking the family uses in summer.
For businesses it's about safe access, presentation and consistency, which usually means a scheduled visit rather than a one-off. We work with both and can arrange timing that suits your day.
How often, and what helps in between
Shaded, north-facing and tree-covered surfaces green up much faster than open sunny ones. Many customers find an annual clean keeps things under control, while heavily shaded properties want it more often.
Between visits, keeping leaves swept off in autumn, keeping gutters clear so water isn't discharging onto walls and paths, and cutting back overhanging planting all slow regrowth noticeably.
Where we work
We cover North and North West London: Enfield, Barnet, Harrow, Edgware, Muswell Hill and Wembley, and all of Hertfordshire, including Watford, St Albans, Hatfield, Welwyn Garden City, Borehamwood and Potters Bar.
Exterior work is often booked together: pressure washing, driveways and patios, gutters and conservatory in one visit, which is usually the most cost-effective way to do it.
Questions People Ask
Pressure Washing: your questions answered
How much does pressure washing cost?
It depends on the area, the surface type, access and how heavy the growth is. Quotes are free: send us the rough dimensions, a photo and your postcode and we'll give you a clear price before anything is booked.
How long does a job take?
Most domestic areas are completed in a single visit. We'll give you a realistic time when we quote so you know what to expect for your day.
Will pressure washing damage my surfaces?
Not when pressure and technique are matched to the material, which is precisely why we assess first. Soft brick, lime pointing, old render and timber all get lower pressure and a different approach from concrete.
Can you clean decking without ruining it?
Yes. Decking is washed with the grain at controlled pressure. Excessive pressure raises the grain and splinters boards, and that's the most common DIY decking mistake we see.
Will all the staining come out?
Algae, moss, lichen and general grime come off well. Oil, rust, paint and deep mineral staining may only improve rather than disappear, and we'll tell you which is which at inspection instead of promising results we can't deliver.
Do you need to use my water and electricity?
Tell us what's available at the property when you enquire and we'll confirm the arrangements before the visit, so there are no surprises on the day.
How often should I have it done?
Shaded and north-facing areas green up fastest and often want annual attention; sunny, open surfaces last longer. Grip underfoot is the practical signal: when it feels slippery after rain, it's due.
Do you work with businesses?
Yes: frontages, forecourts, service yards and access routes, domestic and commercial, scheduled around your operating hours.
Are you insured, and is the work guaranteed?
Yes: £5 million public liability insurance and a service guarantee on every job, backed by 15+ years' experience and a 5.0 rating from 332 TrustATrader reviews.
Which areas do you cover?
North and North West London and all of Hertfordshire: including Enfield, Barnet, Harrow, Edgware, Muswell Hill, Wembley, Watford, St Albans, Hatfield, Welwyn Garden City, Borehamwood and Potters Bar.
