Eco-Friendly House Washing Solutions: What Ontario Homeowners Should Know

As homeowners become more environmentally conscious, questions about the chemicals used in exterior cleaning services have become more common. What goes on your home's siding eventually rinses into your lawn, garden, and potentially local waterways. Here's what you need to know about eco-friendly house washing.

Common House Washing Chemicals

Traditional soft washing uses diluted sodium hypochlorite (bleach), surfactants to help solutions cling to surfaces, and sometimes specialty cleaners for particular stains. When properly diluted and applied, these products are effective at killing biological growth. However, concentrated bleach runoff can damage landscaping and harm aquatic organisms if drainage reaches natural water features.

Environmental Concerns

The primary concerns with house washing chemicals are: runoff affecting garden plants and lawn, chemicals reaching storm drains that discharge to local streams, and residue affecting pets that access treated areas before rinsing. Responsible contractors pre-wet landscaping before application, rinse thoroughly after treatment, and use the minimum effective concentration needed for the job.

Biodegradable Alternatives

Newer biodegradable surfactant-based cleaners can be effective for moderate mold and algae without the environmental impact of bleach-based solutions. These products work on the biological membrane of organisms, causing cell death without persistent toxic residue. For light maintenance cleaning, they can match bleach-based solutions. For severe established growth, some situations still require traditional products for effective results.

Protecting Plants During Washing

Professional house washers protect landscaping by: thoroughly wetting plants with water before applying cleaning solutions (dilutes any overspray), avoiding product application in winds that could carry chemicals to garden beds, rinsing plants again after treatment, and using low-pressure application that minimizes overspray drift. Communicating with your service provider about sensitive plants or vegetable gardens before the service starts ensures they take appropriate precautions.
