Maintaining the appearance of your apartment complex is a crucial aspect of being a property manager. Whether you’re giving tours to prospective tenants or trying to ensure tenant satisfaction, you may consider scheduling professional pressure washing. This is an effective way to remove debris from high-traffic areas and maintain the appearance of your complex.
While this exterior cleaning is a great way to boost curb appeal, you may worry about its impact on your landscaping. Caring for your landscaping is a costly and time-consuming part of property maintenance, and you don’t want this investment to be wasted. In this blog, we’ll discuss how exterior cleaning can harm landscaping and what our team does to ensure its safety through this essential cleaning service.
How Exterior Cleaning Can Harm Your Landscaping
Apartment complexes take great pride in well-maintained landscaping. Lush greenery, colorful flower beds, and trimmed shrubs create a welcoming environment for residents and significantly enhance the property’s curb appeal. However, exterior cleaning, particularly when performed without proper training or care, can put that beautiful landscaping at risk.
One of the most common ways landscaping is harmed is through chemical exposure. The detergents used in soft washing or power washing may contain harsh salts or chemical agents. If improperly applied, these chemicals can leach into the soil or come into direct contact with leaves and roots. This contact can result in dehydration, discoloration, and plant death.
Additionally, excessive water pressure from pressure washing can physically damage delicate plants. Overspray can uproot flowers, strip bark from trees, and compact soil, disrupting natural water absorption. In multi-unit buildings, such as apartments, where landscaping often surrounds sidewalks, building exteriors, and common areas, these risks are more concentrated.

However, the concern doesn’t end with the plants on your property. Landscaping includes mulch beds, irrigation systems, and decorative elements that can be displaced or damaged during cleaning. When exterior cleaning is done without care or training, the aftermath can require costly replanting or repairs.
That’s why understanding the method used and the training level of the crew matters so much, especially in apartment complexes. While maintaining a pristine property is essential, it is even more important to choose the right team for the job, as the wrong team can cost you much more than just your curb appeal.
Common Exterior Cleaning Methods and Their Impact on Plants
There are several common methods used for exterior cleaning, each with its own set of pros, cons, and impacts on your complex’s landscaping:
Pressure Washing
The use of highly pressurized water allows your cleaning team to cut through the toughest debris on your sidewalks, siding, and more. While this is a great way to clean your property, it is far too aggressive for the most delicate surfaces and nearby landscaping. Overspray can knock over flowers, dislodge soil, and cause erosion around tree roots. If chemicals are added to the water to tackle complex debris, mold, or mildew, there is a greater risk of runoff that can seep into flower beds or lawn areas, potentially harming or killing your landscaping.
Soft Washing

Soft washing is a gentler alternative that uses low-pressure water combined with cleaning detergents to break down mold, algae, and grime. However, in the hands of an untrained individual, it can still be harmful to landscaping. The detergents, while biodegradable, can have a high salt content, which may damage delicate plants if overspray occurs or runoff isn’t managed correctly. Without pre-treatment or protection, flowers, ground cover, and low shrubs can suffer from dehydration or discoloration, which is why it is so essential to work with a team of exterior cleaning experts.
Chemical Treatments
Some exterior cleaning projects involve the use of cleaning agents specifically designed for treating mold and mildew. If these chemicals aren’t carefully contained or rinsed properly, they can trickle down into plant beds and affect soil quality and plant life over time. When you work with a team that doesn’t have adequate training, you may notice more runoff than if you work with a team that specializes in protecting and maintaining your property’s landscaping.
How Cardinal Pressure Washing Protects Your Landscaping
At Cardinal Pressure Washing, our team takes landscaping protection incredibly seriously. Our team is trained not just in how to clean your apartment complex, but in how to do it without compromising the surrounding environment. Soft washing is an excellent tool in our cleaning arsenal, but we never underestimate its power and potential risks.
While our detergents are 100% biodegradable, they do have a high salt content once broken down. If used carelessly, they can dehydrate sensitive vegetation. That’s why we implement a multi-step protection process on every job. Before we begin any cleaning, we assess the surrounding landscaping and spray a plant-safe neutralizer when necessary.
This neutralizer helps prevent any adverse reaction from our detergents on leaves, roots, or soil. In many cases, we also apply the neutralizer again after cleaning is completed, especially when working around more delicate plants. In addition to chemical protection, we physically shield landscaping as needed, covering flower beds or redirecting runoff with temporary barriers.
Our technicians are trained in best practices to avoid overspray and runoff issues that could affect the health of your landscaping. Every Cardinal crew member is educated in both property and plant protection, so we’re not just cleaning surfaces across the complex; we’re safeguarding everything around them.
