Will pressure washing damage my render?

Yes, in most cases. Pressure washing can crack render, blow sections off K-rend and monocouche, and strip texture from sand-and-cement. We only soft wash render, using biocide and low pressure instead.

How often does render need cleaning?

It depends on aspect and exposure — shaded, north-facing or coastal-exposed elevations tend to need attention more often than sheltered, south-facing ones. Most properties do well with a clean every couple of years, sometimes longer.

What causes the green staining on my walls?

That's usually algae, which establishes on damp, shaded render and brick. It's cosmetic rather than structural, but it does spread if left, which is why we treat the growth with biocide rather than just rinsing the surface.

My render has cracks — can you still clean it?

We'll look at the cracking before we start. Minor hairline cracks aren't usually a problem for a soft wash, but we'll flag anything that looks like it needs attention beyond cleaning rather than working over it.

How much does render cleaning cost?

It varies with render type, property size, growth level and access, but typically runs from around £150 for a single elevation up to £650 or more for a full detached property. We'll confirm an exact figure with a quote.

Do I need to be home while you work?

No, as long as we can access the areas being cleaned and there's water available. We'll leave the site tidy and can send before-and-after photos if you're not around.

A lot of people assume render cleaning means pressure washing, the same as a patio or driveway. It doesn't, and treating render like a hard surface is how cracking, staining and blown coatings happen, especially on thin monocouche and K-rend systems.

Whether it's a rendered new-build estate, a pebbledash semi from the 1960s–70s, or an older brick terrace with lime mortar, properties in Guisborough each need a slightly different approach — modern monocouche is thin and can be damaged by pressure, while old lime-pointed brick needs low pressure for a different reason: the mortar itself is soft.

If render or brickwork in Guisborough has gone green, black-streaked or lichen-covered, we'll soft wash it back to a clean, even finish — no pressure washer near the render coat, ever.

Steam cleaning for brick and stubborn staining

Steam is used where black streaking or ingrained staining on brick needs extra lift beyond what biocide alone will shift. It works at high temperature rather than high pressure, which suits older brick and mortar that wouldn't take forceful water well.

The biocide and methods behind a proper render clean

The core of a proper render clean is the biocide treatment — a professional-grade solution applied to kill algae, lichen and the black fungal growth that causes streaking, rather than just washing the surface growth away.

We're biocide trained (2024), so application rates and dwell times are matched to the render type and how bad the growth actually is, not a standard spray-and-rinse. Steam is used where black staining on brick needs extra lift, and low-pressure rinsing finishes both render and brick without disturbing the surface underneath.

Shaded render and brick under trees

Render and brick under tree cover or on permanently shaded elevations in Guisborough stay damp longer after rain, and that's exactly the condition lichen and green algae need to take hold — these walls are often the worst-affected on a property even when the rest of the house looks fine.

We give shaded elevations a longer biocide dwell time where the growth is established, since a quick treatment on heavily lichen-crusted render or brick rarely shifts it in one pass.

Homeowners

Protecting the value of your home

Left untreated, algae and lichen on render don't just look bad — trapped moisture behind established growth can eventually affect the render coat itself, and black streaking on brick can mask early signs of pointing that needs attention. Regular soft washing keeps growth from reaching that point, which is cheaper than dealing with render or repointing repairs later.

What affects the price

Two similarly sized properties can price differently depending on render type — monocouche and K-rend usually cost a little more to treat properly than sand-and-cement, since they need more careful handling — and on how much scaffolding or platform access is needed for higher elevations.

Terraced house, front elevation	from around £120–£180
Estate house, all elevations	typically £250–£350
Large detached / high elevations	typically £500–£750
Commercial unit (per elevation)	POA depending on scale

Access on site

Most render and brick cleaning jobs just need reasonable access to an outside tap or our own water supply, and enough room to set up equipment near the elevation being cleaned — tight side passages or gated access are worth mentioning when you book so we can plan for it.
