The cost of commercial building washing depends on factors like building size, condition, and accessibility. On average, prices start at $249 for buildings up to 80 sqm and increase based on square footage and complexity.
Factors such as surface material, dirt level, and whether additional treatments like moss removal are needed can also affect the price. Bundling services, like window or roof cleaning, can offer additional savings.
Understanding these variables helps businesses plan their maintenance budget and keep their property looking its best.

What’s Included in Commercial Building Washing?

A professional commercial building washing service includes several essential steps to ensure a thorough clean.
Here’s what’s typically included:
1. Soft Wash or Pressure Wash
The method used depends on the building’s surface. Soft washing is used for delicate materials like painted surfaces, while pressure washing is applied to more durable materials like concrete and brick.
2. Removal of Dirt, Mould, Mildew, & Grime
The cleaning process targets all buildup that can degrade the appearance and structure of your building, including dirt, mould, mildew, and grime.
3. Eco-Friendly Cleaning Solutions
We use safe, eco-friendly chemicals that effectively clean without harming the environment or your building’s surfaces.
4. Safe Methods for Staff & Customers
The process is designed with safety in mind, ensuring minimal disruption to your business while maintaining a clean and safe environment for both employees and customers.
5. Professional Equipment & Trained Technicians
We use professional-grade equipment and experienced technicians to ensure the job is done efficiently and effectively.
Factors Affecting Commercial Building Washing Cost

Several factors influence the final cost of commercial building washing. Here’s what you need to consider:
1. Building Size
The size of the building is the primary factor. Larger buildings require more time, equipment, and cleaning solutions, leading to higher costs. The bigger the building, the more work involved in cleaning it properly.
2. Accessibility
If the building is hard to access—such as high-rise or with restricted entry points—the cost can increase. Special equipment, like scaffolding or extended ladders, may be required, adding to the overall cost.
3. Surface Material
Different materials require different cleaning methods:
- Concrete and brick: Can withstand pressure washing.
- Wood and painted surfaces: Require softer cleaning methods to avoid damage.
The surface material determines the type of cleaning needed, which can affect the cost.
4. Level of Dirt and Staining
Buildings with heavy dirt, grime, or mould will need additional treatments, such as mould removal or stain treatment, which increases the overall cost. The cleaner the building, the less intensive the work required.
5. Location and Region
Depending on your location, pricing may vary. For example, in Auckland, the minimum service charge is higher, reflecting local operational costs.
Bundle With Other Services for Better Value
Many commercial clients find that bundling multiple exterior cleaning services offers better value and efficiency. Here’s how combining services can help save you time and money:
1. Commonly Bundled Services
- Building Washing: The core service, focusing on exterior surfaces like walls and facades.
- Window Cleaning: Often bundled with building washing to ensure a complete clean.
- Concrete & Car Park Cleaning: Keeping parking areas clean enhances the overall look and safety.
- Gutter Cleaning: Regular gutter cleaning helps prevent water damage and blockages.
- Roof Treatment: Helps extend the life of your roof and prevents long-term damage from moss and debris.
2. Why Bundle Services?
- Cost Savings: Bundling multiple services typically offers a discount compared to booking each service separately. You benefit from reduced labour costs and a more comprehensive service.
- Convenience: Scheduling all your exterior cleaning needs at once saves you time. You only need one visit for all services, reducing the hassle of multiple appointments.
- Thorough Maintenance: Bundling ensures your property is well-maintained in all areas, from the roof to the driveway, improving both appearance and functionality.
Why Regular Commercial Building Washing is Important

Regular commercial building washing is crucial for maintaining your property’s appearance, functionality, and longevity. Here’s why you should invest in regular cleaning:
1. Enhance Curb Appeal
A clean building makes a great first impression on clients, customers, and employees. Regular washing removes grime, dirt, and mould, keeping your property looking fresh and professional.
2. Prevent Long-Term Damage
Dirt, mildew, and mould buildup can cause long-term damage to your building’s exterior. Regular cleaning helps prevent decay, corrosion, and staining, extending the lifespan of your property and saving on future repairs.
3. Maintain a Safe Environment
Accumulated dirt and grime can make surfaces slippery, increasing the risk of accidents. Regular cleaning removes hazards and ensures your building remains safe for staff and visitors.
4. Comply with Health and Safety Standards
For businesses in industries like food, healthcare, or retail, keeping the exterior clean is essential for maintaining health and safety standards. A well-maintained building helps reduce the risk of pests, mould, and allergens.
5. Improve Property Value
A well-maintained building is more attractive to potential tenants or buyers. Regular washing boosts your property’s value by preserving its condition and enhancing its appeal.
How Often Should You Schedule Commercial Building Washing?

The frequency of commercial building washing depends on various factors, including the building’s location, exposure to dirt and weather, and the type of business you operate.
Here’s a guide to help you decide how often to schedule this essential service:
1. Annual or Semi-Annual Cleaning
For most commercial buildings, washing once a year or twice a year is sufficient. This ensures that your property maintains its appearance, prevents dirt and grime buildup, and preserves the integrity of the exterior surfaces.
2. After Severe Weather
Buildings exposed to heavy storms, rain, or winds may need washing more frequently. Post-storm cleaning removes debris and prevents long-term damage caused by accumulated dirt, leaves, and moisture.
3. High-Traffic Areas
If your commercial building is located in a busy area with a lot of foot or vehicle traffic, you may need cleaning more often. High-traffic locations collect dirt and pollutants faster, which can impact the building’s appearance and cleanliness.
4. Industry-Specific Recommendations
Certain businesses, like restaurants, healthcare facilities, or retail shops, may need more frequent cleanings due to higher hygiene standards. For these industries, consider scheduling cleaning every 3 to 4 months to maintain a professional and safe environment.
Conclusion
Commercial building washing is an essential service for maintaining your property’s appearance, safety, and long-term value.
Whether you need cleaning for aesthetic reasons, to prevent damage, or to meet industry standards, regular washing ensures your building stays in top shape.
