Question 1

Why does my render wall turn green?

Accepted Answer

The green colouring on exterior render is algae, which thrives in Ireland's damp, mild climate. It is most common on north-facing walls with limited sunlight, walls near trees and hedges, and older pebbledash render that has a rougher surface where spores can settle.

Question 2

Is soft-wash safe for pebbledash and smooth render?

Accepted Answer

Yes. Our soft-wash method is appropriate for both smooth render and pebbledash finishes. We adjust the pressure to suit the surface. High-pressure washing can dislodge pebbles from pebbledash, which is why we use the low-pressure soft-wash approach.

Question 3

Can you clean painted walls without stripping the paint?

Accepted Answer

Yes. We select cleaning solutions appropriate for painted surfaces and apply at a pressure that removes growth without affecting the paint layer. On older or loose paint, we will advise you of any areas that may need attention.

Question 4

How long does wall cleaning last before the algae returns?

Accepted Answer

Without a coating, algae can begin to return within two to three years in a typical Irish environment, particularly on shaded or north-facing walls. Applying a wall coating after the clean significantly extends the clean period.

Question 5

Can you remove dark streaks and staining from render?

Accepted Answer

Yes. Dark streaks on render are typically algae or mould growth. Our cleaning solution breaks down and kills the organic matter, removing the staining. Mineral staining or paint discolouration may not be fully removable by cleaning alone.

Question 6

Is it necessary to clean walls before selling a house?

Accepted Answer

A clean exterior makes a significant first impression on prospective buyers. Green algae, dark streaks and stained render are common reasons valuers note the exterior as dated. A wall clean and coating is one of the most cost-effective improvements you can make before selling.

Question 7

Do you clean walls in Co. Clare and Co. Tipperary as well as Limerick?

Accepted Answer

Yes. We cover a 30-mile radius from Limerick city, which includes towns in Counties Clare, Tipperary and South Cork as well as across Co. Limerick. See our locations page for the full list.

Question 8

What causes lichen on exterior walls?

Accepted Answer

Lichen is a combination of algae and fungi that forms a crusty growth on damp, textured surfaces. It is particularly stubborn because it anchors itself into porous surfaces. A specialist biocidal treatment is required to kill lichen at the root before it can be removed.

Question 9

How much does wall and render cleaning cost?

Accepted Answer

Cost depends on the size of the property, the extent of growth and the surface type. We provide free, no-obligation quotes with transparent itemised pricing. Contact us for a quote specific to your property.

Question 10

Do you need a scaffold to clean walls?

Accepted Answer

For most standard residential properties we can reach all wall areas from safe ladders and reach equipment. For taller or awkwardly accessed elevations, we will discuss what access equipment is needed and include it in the quote.
