What is balcony cleaning?

Balcony cleaning involves thoroughly cleaning the balcony floor, the railings, and the balustrade, including the drain and the edges. Balcony cleaning removes dirt that accumulates outdoors and cannot be removed with a broom and a bucket of water.

A balcony is exposed to rain, wind, and birds all year round. This results in a stubborn layer of green deposits, moss, bird droppings, and fine dust on the tiles and concrete. This layer makes the floor slippery—and therefore unsafe—and, over time, damages the grout and the coating. Cleaning the balcony regularly prevents this damage and keeps the outdoor space usable.

Our Approach: How Our Specialists Clean Your Balcony

Every balcony requires a unique approach. Our specialists determine, on a case-by-case basis, the method that will deliver the best results safely and efficiently.

Removing Green Growth from the Balcony

Green growth on a balcony is a living layer of algae and moss that adheres to pores and joints. Simply hosing it off leaves the roots behind, causing the growth to return within a few months. Our specialists clean the surface and then treat it to keep the growth from returning for longer.

Hygienic Removal of Bird Droppings and Pigeon Droppings

Bird droppings contain bacteria and can be corrosive to concrete, paint, and aluminum. Our specialists loosen the buildup and then disinfect the surface. If you’re experiencing a persistent problem with pigeons or seagulls, read more on our page about removing bird droppings from your balcony.

Large Roofs and Systems

Is your system located on an industrial building, a warehouse, or the flat roof of a distribution center? If so, we’ll use aerial work platforms or roof safety equipment, and our VCA-certified team will work in accordance with your site’s safety regulations. We can even handle a roof with hundreds of panels. We’ll coordinate the schedule with your business operations so that your processes can continue as usual.

Balustrades, Fencing, and Balcony Glass

Cleaning the balcony railing is a standard part of the service, including the underside of the railing and the mounting points. Glass balustrades and balcony glazing require a different technique than metal. For streak-free glass, we combine the service with our window cleaning.

Cleaning a Balcony by Surface Type

The subfloor determines the pressure and the product to use. The wrong combination will permanently damage the floor.

Cleaning a Concrete Balcony

Cleaning a concrete balcony requires caution when using pressure. Concrete is porous, which means dirt penetrates deep into the surface, and excessive pressure can expose the cement matrix. Our specialists clean the concrete floor using a pressure level tailored to the condition of the concrete, ensuring that the top layer remains intact. In the case of a coated or cracked concrete floor, we first assess whether cleaning is appropriate.

Tiles, Natural Stone, and Grout

Tiles are easy to clean, but the grout is fragile. Loose grout washes away under too much pressure, allowing water to seep under the tiles. We clean each tile individually and treat the grout separately.

Wooden decking and artificial turf

Wood should be cleaned in the direction of the grain; otherwise, splinters may form. Artificial turf should be brushed and rinsed without flattening the fibers. We use a lower pressure setting for both than we do for stone.

Who We Clean Balconies For

Our specialists work for clients with a single balcony as well as for complexes with hundreds of balconies. Our approach scales accordingly, while the quality remains the same.

  • Homeowners' Associations and Property Management. Regular cleaning of all balconies in a complex, coordinated through a single point of contact.
  • Housing Associations. Cleaning in cases of overdue maintenance, tenant turnover, or resident complaints.
  • Landlords and real estate agents. A presentable balcony at the time of move-in, during a showing, or at the time of sale.
  • Commercial buildings and restaurants. Balconies and rooftop terraces that are visible to guests and visitors.
  • Residential customers. One balcony, fixed price, completed at a time that’s convenient for you.

If you combine this service with facility cleaning for your building, a single point of contact will handle all maintenance.

How often do you have your balcony cleaned?

For most balconies, one thorough cleaning per year is sufficient. Balconies facing north or located under trees require two cleanings, as green growth returns more quickly there due to shade and moisture. We clean balconies in complexes affected by pigeons more frequently, usually two to four times a year. We’ll advise you on a cleaning schedule that suits the location and use of the property.

How much does it cost to clean a balcony?

The cost of cleaning a balcony can vary depending on the situation. The size of the balcony, its accessibility, and the extent of the dirt and grime all play a role. At 12B Clean, you’ll receive a clear quote for the work upfront. That way, you’ll know exactly what to expect and won’t face any surprises afterward.

Cleaning it yourself may sometimes seem like a simple and cost-effective solution—for example, using a rented pressure washer. However, this does carry certain risks. Water can end up on balconies or facades below, and improper techniques can damage joints, coatings, or other surfaces.

12B Clean has the right equipment, cleaning products, and expertise to effectively tackle various types of dirt and grime. We take into account the materials used in the balcony and the surrounding area to ensure that the cleaning is performed safely and carefully.

Are there multiple balconies within the same apartment complex? If so, we can prepare a customized project quote.

Clean a concrete balcony using low to medium pressure and a cleaning agent suitable for porous surfaces. Excessive pressure exposes the cement matrix, causing the concrete to attract dirt more quickly and eventually crumble. Treat the surface after cleaning; otherwise, the green buildup will return within a few months.

For a balcony, use water mixed with a cleaning agent suitable for the surface: an alkaline cleaner for concrete and tiles, and a neutral cleaner for wood and artificial grass. Chlorine is not recommended for balconies, because it can flow through the drain onto your downstairs neighbors’ balcony and damage their plants.

Yes. The fencing, handrails, and balustrades are included as standard in the service, including the undersides and mounting points. We clean glass balustrades using the same technique we use for window cleaning.
