Why Nanaimo Homeowners Choose Green Tech

The Green Tech Method: Soft Washing, Not Surface Damage

The old-school approach to exterior cleaning in Nanaimo was to blast everything with a 2,500+ PSI pressure washer. That approach strips paint, forces water behind the siding and under the shingles, blows the gutter seams apart, and leaves zebra-striped concrete. We do it differently:

  • Soft washing on siding, roofs, and gutters. Low-pressure application of biodegradable cleaning solutions kills moss, algae, and mildew at the root instead of just knocking the visible growth off. Surfaces stay cleaner longer, and nothing gets damaged.
  • High pressure only where it belongs. Concrete, brick, and stone get proper pressure washing with rotary surface cleaners for even, thorough results.
  • Eco-friendly cleaning agents, always. Every product we use is biodegradable and safe for your family, pets, gardens, and the waterways we all share. We’ll tell you exactly what we’re applying for and why before we start.
  • Property protection as standard practice. We cover landscaping, protect delicate surfaces, and do a full site cleanup before we consider any job finished.
  • Assessment before action. Every property is evaluated first. Cedar shakes, vinyl siding, stucco, asphalt shingles, and painted wood all require different handling, and get it.

Frequently Asked Questions

How often should you clean the exterior of your house?
Most homes should receive a thorough exterior cleaning at least once a year. In damp coastal areas such as Nanaimo, surfaces may need more frequent attention because moss, algae, mildew, and lichen grow quickly. Roofs and gutters should also be inspected between annual cleanings.
Soft washing is generally the safer option for siding, roofs, painted surfaces, and other delicate materials. It uses low pressure with appropriate cleaning solutions to remove organic growth. Pressure washing is better suited to durable surfaces such as concrete, brick, and some types of stone.
Spring and fall are popular times for exterior cleaning, but professional services can be scheduled whenever weather conditions allow. Spring cleaning removes winter buildup, while fall maintenance helps clear leaves, debris, and organic growth before wetter weather arrives.
Many residential exterior cleaning jobs can be completed within several hours, while larger properties or projects involving multiple services may take longer. Roof moss removal, extensive gutter cleaning, and heavily soiled surfaces can also affect the timeframe.
Professional exterior cleaners should take steps to protect gardens, lawns, and landscaping throughout the job. Green Tech Property Care uses biodegradable cleaning agents and protects surrounding areas before cleaning begins.
Algae thrives in damp, shaded areas, which is why it commonly appears on north-facing walls and surfaces with limited sunlight. Nanaimo’s wet coastal climate can encourage recurring growth, especially when siding remains damp for extended periods.
High-pressure washing is generally not recommended for roofing materials. Strong pressure can damage shingles and remove protective granules. Professional roof cleaning typically involves careful moss removal and treatment without blasting the roof with high-pressure water.
A green driveway is usually caused by algae or moss growing in damp conditions. Shaded concrete can stay wet for long periods, creating ideal conditions for organic growth. Cleaning the surface can improve its appearance and reduce slippery areas.
