Facade cleaning: What does it cost?

On average, facade cleaning costs around €20 per square meter, with prices ranging between €5 and €35 per square meter, depending on the method and surface.

Homeowners often reach for paint and brushes too quickly when dealing with dirty or algae-covered facades. In many cases, a professional cleaning is enough to restore the facade’s appearance at a much lower cost.

For brick or clinker facades, which are not painted, cleaning is the only way to freshen up the exterior after years of dirt buildup.

Factors Affecting Facade Cleaning Costs:

• Size of the facade

• Type of facade

• Cleaning method

• Degree of dirt and algae growth

• Labor costs of the specialist company

• Additional costs (scaffolding or lifting equipment)

• Disposal of wastewater

Why Hire a Professional?

Most people don’t have the proper cleaning agents or equipment for a safe and thorough facade cleaning. A professional can assess the dirt level and choose the right cleaning method.

Moreover, a qualified cleaning company also takes care of wastewater disposal, which must not be released into the ground.
This typically adds €100–€150 in disposal fees.

Possible Additional Costs:

For facades higher than 10 meters, lifts or scaffolding are required:

• Lift: €100–€200 per use

• Scaffolding: €4.50–€15 per m² (for facades above 20 meters)

Common Cleaning Methods & Costs

1. High-pressure cleaning (simple):
€5–€15 per m²
Removes dirt and algae with hot water under pressure. No scaffolding is required for walls up to 10 meters.

2. High-pressure cleaning with impregnation/sealing:

• €5–€20 per m²
  Prevents damage from weather and moisture. Recommended for brick facades and other porous materials.

3. Sandblasting:
€20–€25 per m²
Used for stubborn dirt; requires care on delicate surfaces.

4. Dry ice blasting:
€90–€160 per hour
Most expensive but also the gentlest and fastest method.
No wastewater is produced, making it environmentally friendly and suitable even for historic buildings.
