How long does render cleaning take?

Most single properties take a few hours to a day, depending on size, growth level and access. Larger or commercial elevations can take longer — we'll give you a time estimate with your quote.

Can you clean K-rend?

Yes. K-rend is soft washed with biocide and rinsed at low pressure — never pressure washed, since the coloured finish is thin enough to be damaged by force.

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.

Do you offer a free quote?

Yes — send a few photos or ask for a site visit and we'll give you a proper quote based on render type, size and access, with no obligation.

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.

Do you clean commercial and industrial premises?

Yes, we clean render, brick and block on shops, offices and industrial units, usually scheduling around opening hours so it doesn't disrupt business.

Safe Render Cleaning for Thornaby Homes

Professional render and brick cleaning across Thornaby. Soft wash and steam methods protect your render while removing algae and lichen for good.

Brickwork gets the same care. Steam or soft washing lifts black streaking and algae without eroding old lime mortar joints, which is where a pressure washer does most of its damage on older brick properties.

Call Trevor on 07501 060609 for a quote based on elevation size, render type and access, or ask for a free look at the property first if you're not sure what you're dealing with.

We soft wash render and use steam or gentle low-pressure methods on brick, adjusting biocide dwell time and rinse pressure to what the surface can actually take.

Trained in the method that actually matters

Fully insured: Covered for peace of mind on every job we do.

Shaded render and brick under trees

Render and brick under tree cover or on permanently shaded elevations in Thornaby 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

Getting a property ready to sell or let

Render that's gone green or brick that's streaked black is one of the first things a buyer or tenant notices from the kerb, before they've even seen inside. A soft wash clean is one of the more cost-effective things you can do before photos or viewings — it lifts the whole look of the property for a fraction of what a repaint or re-render would cost.

How the process differs by surface

1
Render assessment
K-rend, monocouche, pebbledash and sand-and-cement each get treated slightly differently based on thickness and texture.
2
Brick and mortar check
Pointing condition is noted, especially on older lime-mortared brick, so pressure stays low enough not to erode it.
3
Biocide on render
Render gets a biocide soft wash with dwell time suited to how established the algae or lichen is.
4
Steam on brick
Brickwork with black streaking or ingrained staining often gets steam treatment for extra lift.
5
Rinse and inspect
Both surfaces are rinsed at low pressure and checked together before we finish up.

Protecting what's around the property

Before any biocide goes on, we cover or move planting, garden furniture and anything nearby that shouldn't come into contact with it. We're spill management trained, so runoff and unused product are handled and disposed of properly, not left to find their way into drains or beds.

What a finished render or brick clean looks like

A finished job means green and red algae gone, black streaking lifted, lichen removed, and the render or brick colour back close to what it was when the wall was first finished.

Because the biocide has actually killed the growth rather than just removed it visually, regrowth is slower than it would be after a quick pressure rinse. We take before-and-after photos of every job, so you can see exactly what changed.
