Weather, pollution, moss, algae and other deposits can discolour a façade over time. With an appropriate cleaning method, the original appearance can often be largely restored.
Looking for a professional façade cleaning company? Nu-Isoleren provides exterior façade cleaning services throughout Flanders and Wallonia. We assess the wall material, condition of the pointing and type of contamination before selecting a suitable approach. This helps us clean your exterior walls while taking care to protect the existing surface.
Dirt affects appearance and can retain moisture. Proper cleaning also makes it easier to assess the actual condition of the façade.
Professional façade cleaning can reveal the original appearance of brick or stone again and often provides a good preparation for repairs or hydrophobic treatment. The aim is to clean effectively without unnecessarily damaging the substrate.
Depending on the substrate, atmospheric pollution, algae, moss, soot and general staining can be addressed.
A façade is exposed for years to rain, dust, traffic pollution, moss and algae. Soiling is not only cosmetic; deposits can also hide small defects. We therefore assess the wall material, pointing and existing finishes before selecting a cleaning method.
Professional façade cleaning requires an approach suited to the building material and type of contamination. For brick façades, we consider factors such as brick condition, pointing and the presence of moss, algae or atmospheric deposits.
Natural stone, render and porous finishes may be more sensitive to water pressure or cleaning products. We therefore assess the surface before determining an appropriate cleaning method and intensity, aiming to remove contamination without unnecessary damage.
Not every façade is immediately suitable for thorough cleaning. Loose pointing, damaged bricks, cracks or fragile surface finishes can increase the risk of damage.
In these situations, we assess whether repairs are needed first or whether a more suitable treatment is possible. The actual condition of the façade determines which work can be carried out safely.
Cleaning can be a stand-alone service or the first step in broader façade renovation. Once clean, cracks, pointing defects and damage are easier to assess.
Depending on the facade, subsequent steps may include repairs, the application of a water-repellent treatment (hydrofuge), or another type of finish. Cleaning ensures that any follow-up work can be planned on a clean surface that is suitable for inspection.
After cleaning, a suitable mineral façade can sometimes receive a water-repellent hydrofuge treatment. Read more on our hydrofuge page.
After cleaning, a suitable mineral façade can in some cases be protected with a hydrophobic treatment. A clean substrate helps the impregnation penetrate more evenly. Cleaning and hydrofuge are separate steps and are only combined where technically appropriate.
We adapt the method to the substrate.
We begin with a visual assessment and then choose the most appropriate technique. During the work we monitor both cleaning performance and the response of the substrate. Afterwards we can assess whether repairs or an additional protective treatment would be useful.
We assess materials, joints and contamination.
The technique and intensity are matched to the substrate.
Contamination is removed systematically.
We evaluate whether repairs or further treatment are useful.
The cost of professional façade cleaning depends on the total surface area, wall material, level of contamination and the cleaning method required.
Accessibility also affects the price. Taller buildings, difficult access or the need for scaffolding or lifting equipment may increase the work involved. Preparatory repairs or additional façade treatments can influence the final cost.
As every façade is different, we do not publish a fixed price per square metre. Would you like to know how much cleaning your exterior walls will cost? Request a free, no-obligation quote for an estimate tailored to your property.
The result of façade cleaning depends on the wall material, type of contamination and condition of the surface. Explore our projects to see how professional cleaning can improve the appearance of an exterior wall.
Answers about pricing, cleaning methods, sensitive substrates and hydrofuge.
Not every façade should be cleaned in the same way. Nu-Isoleren examines the façade material, type of contamination and condition of the surface before choosing an appropriate cleaning method.
There is no universal price per square metre. The total area, contamination level, accessibility and required cleaning method all affect the final cost. Nu-Isoleren therefore prepares a quotation tailored to your property.
This depends on the type of finish and the condition of the surface. Render and certain natural stones may be sensitive to particular cleaning methods. We therefore assess the façade before deciding which treatment is appropriate.
Yes. Where the façade is suitable, cleaning can be followed by a water-repellent treatment. The surface is first cleaned and prepared before the protective treatment is applied.
