What Does Impregnation Actually Cost?

1. Prices per m²

Facade cleaning (depending on method)

• Steam cleaning: 5 – 10 euro per m²
• High-pressure cleaning: 8 – 15 euro per m²
• Sandblasting / Wet blasting: 12 – 22 euro per m²
• Chemical cleaning: 15 – 20 euro per m²

Impregnation (after cleaning)

• Impregnation separately: 6,50 – 10 euro per m²
• Is almost always only carried out after cleaning and possibly grouting.

2. Combined price (cleaning + impregnation)

When both activities are carried out in one process, the price per m² is more favorable than when the activities take place separately.

• Steam cleaning + impregnation: 15 – 18 euro per m²
• High-pressure cleaning + impregnation: 17 – 22 euro per m²
• Sandblasting + impregnation: 20 – 30 euro per m²
• Chemical cleaning + impregnation: 21 – 28 euro per m²
• Mist blasting + impregnation: 21 – 28 euro per m²

3. Examples of total costs

Terraced house – 60 m² facade (high pressure):

• Cleaning + impregnation: 60 × 20 = 1,200 euros

Corner house – 100 m² facade (sandblasting):

• Cleaning + impregnation: 100 × 25 = 2,500 euros

Detached house – 150 m² facade (mist spraying):

• Cleaning + impregnation: 150 × 24 = 3,600 euros

4. Factors that influence the costs

1. Surface area of the facade
2. Degree of pollution (light deposit or heavy moss/soot)
3. Accessibility (scaffolding or aerial platform needed?)
4. Chosen cleaning method
5. Combining with other work such as renewing joints

5. Why impregnate after cleaning?

• Protection against moisture and frost
• Reduced risk of moss and algae
• Longer lifespan of the facade
• Dry walls insulate better

An impregnated facade stays clean much longer than an untreated facade.

Conclusion

In 2025, the combined costs for facade cleaning and impregnation will be between approximately 15 and 30 euros per m², depending on the cleaning method and the condition of the facade. For an average corner house, this means an investment of approximately 2,000 to 3,000 euro.
