Pressure washing is an essential maintenance technique for commercial properties and is crucial for preserving the building's aesthetic appeal and structural integrity. This method uses a high-pressure spray of water to remove dirt, grime, mud, mold, and other stubborn stains from surfaces and objects like buildings, vehicles, and concrete.
In this blog, we'll explore the fundamentals of pressure washing, detailing its benefits, appropriate techniques, and safety measures to help property owners make informed maintenance decisions. Let's dive in!
What is pressure washing?
Pressure or power washing involves using a high-pressure water spray to blast away unwanted substances from hard surfaces. The power generated by a pressure washer can vary significantly; residential models typically exert between 750 to 3,000 psi (pounds per square inch), whereas commercial pressure washers can go much higher, offering deep cleaning capabilities that are much more effective than conventional cleaning methods.
This method is particularly effective for large surfaces found in commercial settings, like parking lots, sidewalks, and exterior walls. Pressure washing is capable of handling various types of dirt and debris, including:
- Built-up dirt and mud
- Stubborn stains from oil or grease
- Graffiti and other unwanted paint markings
- Mold, mildew, and algae growth, which are particularly common in humid climates
Benefits of pressure washing for commercial properties
Enhancing the property's curb appeal
First impressions are vital in any business, and your property's exterior often serves as your company's face. Regular and professional pressure washing can dramatically improve the appearance of commercial buildings, making them more inviting to clients, customers, and employees. Clean, well-maintained exteriors reflect positively on a business's values and professionalism.
Preventing damage and costly repairs
Over time, build-ups of dirt, algae, and other substances can cause substantial damage to building surfaces. Bird droppings are especially acidic and can weaken roof materials or paint if not cleaned regularly.
Similarly, algae and mold can eat away at siding and roof shingles, potentially leading to costly repairs. Regular pressure washing prevents these build-ups, protecting the building's materials and delaying the need for repairs and replacements.
Contributing to a healthier environment
Pressure washing removes potentially harmful substances such as pollen, pollutants, dust, mold, algae, and bird droppings, all of which can affect the health of those who use the building. By eliminating these substances, pressure washing can help limit the risk of respiratory problems and other health issues for employees and visitors, contributing to a healthier workplace environment.
Extends the lifespan of building materials
Pressure washing can significantly extend a building's exterior surface lifespan by removing harmful elements that can accelerate aging and decay. Regularly cleaning surfaces like brick, concrete, and other facade materials removes corrosive contaminants such as salt, industrial pollutants, and bird droppings, which can cause deterioration over time. By maintaining these surfaces regularly, businesses can defer expensive restoration work and extend the longevity of their properties.
Enhances safety and reduces liability
Slippery substances such as algae, mold, and mildew can pose serious slip hazards, especially in high-traffic areas like walkways, entryways, and parking lots. Regular pressure washing of these areas helps to remove such hazards, thereby reducing the risk of slips and falls. This protects customers and employees and reduces the property owner's liability and the potential for costly lawsuits due to accidents.
Environmental compliance
In many areas, businesses must maintain specific cleanliness standards as part of environmental regulations, particularly concerning stormwater runoff. Pressure washing can help manage waste and pollutants that might otherwise enter storm drains and affect local waterways.
By using environmentally friendly cleaning agents and proper water recovery methods, businesses can ensure they meet local environmental standards while maintaining their premises.
Increases property value
For commercial properties, the first impression can also impact property value—a clean, well-maintained exterior appeals to potential renters, buyers, or investors. Regular pressure washing can enhance the property's curb appeal, making it more attractive in the competitive commercial real estate market. This could directly influence the property's valuation, yielding a higher return on investment regarding lease or selling.
Saves time and effort
Compared to traditional cleaning, pressure washing is an efficient and effective way to clean large surfaces quickly. This is particularly beneficial for commercial properties with extensive exterior surfaces that need regular cleaning to maintain their appearance and integrity. Pressure washing reduces the labor-intensive efforts required and can be scheduled during off-hours, minimizing disruption to daily business operations.
Choosing the right pressure washing equipment
Pressure washers come primarily in two types: electric and gas-powered. Each has its specific applications and benefits:
- Electric Pressure Washers: These units are quieter, lighter, and generally easier to handle than their gas counterparts. They are ideal for light to moderate cleaning tasks and small commercial environments with minimal noise levels.
- Gas-powered Pressure Washers: Known for their power and mobility, they offer higher psi (pounds per square inch) and GPM (gallons per minute) ratings, making them suitable for heavy-duty cleaning tasks on more significant commercial properties. They can also operate independently of a power source, adding to their versatility in various settings.
Pressure washing techniques for different surfaces
Delicate surfaces require careful handling to avoid damage:
- Lower Pressure Settings: Use the lowest effective pressure setting and a wide-angle or fan nozzle to distribute the water's force over a broader area.
- Soft Washing Techniques: For extremely delicate surfaces like stained glass or intricate metalwork, consider soft washing, which uses lower water pressure and specialized cleaning solutions to remove dirt gently.
Removing tough stains requires a more aggressive approach:
- Hot Water Pressure Washing: Hot water can break down oil and grease more effectively than cold water, making it ideal for these stains.
- Specialized Cleaning Agents: Use detergents or degreasers designed for pressure washers to help break down tough grime and graffiti. Always choose environmentally friendly chemicals that are effective yet do not harm the landscape or local waterways.
Safety precautions when pressure washing
Safety is paramount when operating high-powered machinery:
- Personal Protective Equipment (PPE): Operators should wear goggles, gloves, ear protection, and non-slip shoes.
- Secure The Area: Use barriers or signs to keep pedestrians at a safe distance from the cleaning area to avoid accidental injury from flying debris or slips.
Environmental protection should be considered during pressure washing projects:
- Water Runoff Management: Implement measures to prevent contaminated water from entering storm drains. Water reclamation mats or barriers should be used to collect and dispose of wastewater according to local regulations.
- Responsible Chemical Use: To minimize environmental impact, choose cleaning solutions that are biodegradable and non-toxic. Always follow local guidelines for chemical use to protect wildlife and water quality.
Maintenance tips to extend the benefits of pressure washing
Proper maintenance following a pressure washing treatment can prolong the cleanliness and preservation of your commercial property's exterior. Here's how to keep the benefits going long after the initial wash:
Routine cleaning schedules
Consistency is vital in extending the effects of pressure washing. Establishing a routine cleaning schedule helps in several ways:
- Prevents Build-up: Regularly scheduled pressure washing prevents the accumulation of dirt, grime, pollutants, and organic growths like mold and mildew, which can be harder to clean if allowed to build up over time.
- Seasonal Considerations: Adjust the frequency of pressure washings based on seasonal needs—more frequent in autumn to clear leaves and debris and after winter to clean off salts and melted snow residues that can damage surfaces.
- Visual Inspections: Include regular visual inspections to catch issues early. This proactive approach ensures that stains or damages can be addressed promptly before they become more severe or costly.
Post-cleaning care for different surfaces
After pressure washing, different surfaces may require specific care to maximize the longevity of the cleaning:
- Sealing Surfaces: For materials like concrete and stone, applying a sealant after cleaning can protect the surface from moisture penetration, staining, and wear. Sealants also help block UV rays that can degrade surfaces over time.
- Protective Treatments: Wood surfaces may benefit from oils or stains that enhance their appearance and provide a protective layer against weathering and UV damage.
- Regular Assessments: Monitor treated areas for signs of wear or re-soiling. Prompt attention to these areas can help maintain the integrity of the cleaning and the material underneath.
Gentle cleaning methods between pressure washings
In between major cleanings, maintaining surfaces with gentler methods can extend the life of the pressure washing and prevent the need for frequent high-pressure treatments:
- Soft Washing: For delicate areas or just for maintenance, soft washing—which uses less pressure and more detergents—can keep buildings looking their best without the wear and tear of high-pressure water.
- Sweeping and Rinsing: Regular debris sweeping and gentle rinsing with a garden hose can keep surfaces clean and inspectable, delaying the need for another pressure wash.
