The Importance of Exterior Building Cleaning
Before diving into the how-to, it’s crucial to understand why washing the exterior of buildings is so important for janitorial businesses. Cleaning a building's exterior:
1. Improves Curb Appeal: Clean buildings attract more customers and tenants, which is vital for commercial properties.
2. Extends the Lifespan of Building Materials: Dirt and grime can wear down materials over time. Regular cleaning helps prevent damage.
3. Promotes a Healthy Environment: Mildew, mold, and algae can accumulate on building surfaces, potentially affecting air quality and leading to health issues for those inside the building.
4. Protects Property Value: Routine cleaning and maintenance help maintain the building’s value and prevent costly repairs.
Step-by-Step Guide to Washing the Outside of Buildings
For a janitorial business, exterior cleaning typically involves a combination of pressure washing, soft washing, and manual cleaning depending on the type of surface. Here’s a step-by-step guide to ensure the job is done right.
1. Assess the Building’s Surface
Different buildings are made from different materials, which require different cleaning techniques. Common exterior surfaces include:
- Brick: Porous and prone to moss and mildew buildup.
- Concrete: Often found on commercial buildings and requires high-pressure cleaning.
- Vinyl siding: Popular for residential buildings, can be cleaned with low-pressure washing.
- Wood siding: Requires gentle cleaning to avoid damage.
Before starting the cleaning process, inspect the surface to determine its material, condition, and any areas that may require special attention (e.g., cracks or damaged areas).
2. Select the Right Cleaning Method
The cleaning method you choose will depend on the building’s material and the level of dirt or buildup on the surface. There are two primary methods for washing the outside of buildings:
Pressure Washing
Pressure washing uses high-powered water jets to clean surfaces, and it’s ideal for harder materials like concrete, brick, and stone. Here are some tips for using pressure washing effectively:
- Use the Right Pressure Setting: Higher pressure is required for harder surfaces like concrete, while softer materials like vinyl and wood require lower pressure.
- Maintain a Safe Distance: Holding the pressure washer too close to the surface can cause damage, so maintain at least 12 to 18 inches of distance.
- Work in Sections: Move the pressure washer in a sweeping motion and work in small sections to ensure thorough cleaning.
Soft Washing
Soft washing involves using lower pressure combined with cleaning solutions, making it ideal for more delicate surfaces like vinyl siding and wood. Soft washing is effective at killing mold, mildew, and algae without causing damage.
- Use Environmentally Friendly Cleaning Solutions: Opt for biodegradable and non-toxic cleaners to avoid harming landscaping and surrounding areas.
- Rinse Thoroughly: After applying the cleaning solution, be sure to rinse thoroughly to remove all soap and residue.
3. Prepping the Area
Before starting the cleaning process, it’s essential to prepare the surrounding area to protect landscaping, windows, and doors. Here’s what to do:
- Cover Plants and Shrubs: Use plastic sheeting or tarps to protect plants from chemicals and high-pressure water.
- Close Windows and Doors: Ensure all windows and doors are tightly closed to prevent water from seeping inside.
- Move Furniture and Decorations: If there are any outdoor furnishings or decorations near the building, move them to avoid damage.
4. Apply Cleaning Solutions
For most buildings, a cleaning solution will help break down dirt, grime, and algae more effectively than water alone. When applying cleaning solutions, follow these guidelines:
- Choose the Right Detergent: For janitorial businesses, it’s essential to use detergents specifically designed for exterior cleaning. Many are formulated to remove mold, mildew, and algae without damaging surfaces.
- Let the Solution Sit: After applying the cleaning solution, let it sit for 5-10 minutes to break down grime, but don’t let it dry on the surface.
5. Scrubbing and Spot Cleaning
In some cases, stubborn stains, mold, or dirt may require additional scrubbing. Use a long-handled brush with soft bristles to gently scrub problem areas. Avoid using abrasive materials that could damage the surface.
6. Rinse and Dry
After cleaning, it’s time to rinse the building. If using a pressure washer, switch to a lower-pressure setting for rinsing. Be sure to rinse from the top down, ensuring all soap and residue are removed.
Allow the building to air dry, or use a leaf blower to expedite drying in shaded areas.
7. Post-Cleaning Inspection
Once the building has dried, inspect the exterior to ensure no spots were missed and that all areas are clean and free from streaks or residue. If necessary, perform touch-ups.
