Why These Exterior Pressure Cleaning Results Last (And How Glason Makes the Difference)
This residential pressure cleaning project in Springfield showcases how dramatically a property can be transformed with the right treatment. The home’s outdoor surfaces were suffering from a combination of built-up grime, stubborn mould, and lichen—common exterior surface contaminants that thrive in shaded, moisture-prone areas.
The driveway was heavily discoloured and patchy, the letterbox had lichen growth eating into the surface, and the back courtyard and side paths were dulled by years of exposure to weather and organic build-up.
Mould and lichen are more than just visual eyesores. Mould holds moisture and promotes decay, while lichen bonds tightly to surfaces and can cause long-term damage if not removed properly.
By combining high-pressure cleaning with targeted biocide treatment, Glason High Pressure Cleaning restored this home’s external areas safely and effectively—improving both the appearance and longevity of the surfaces.
Before & After - Front of House & Back Courtyard




What We Cleaned
This Springfield home had multiple outdoor areas affected by different types of surface contamination—each requiring its own approach. Years of exposure to weather, moisture, and everyday use had left visible signs of wear, with build-up varying from lichen and mould to general grime across different surfaces. A tailored, surface-specific cleaning plan was needed to restore the property safely and effectively.
Driveway
The exposed aggregate driveway showed clear signs of wear and discolouration. Years of traffic, organic grime, and lichen had caused dark patches, uneven shading, and a dull, weathered look. Lichen growth in particular had become embedded in the surface, especially in shaded sections closer to the garage doors.

Letterbox
The brick letterbox was visibly overrun with lichen—creating a patchy, light-green crust across the surface. While lichen may grow slowly, it bonds aggressively and can degrade masonry and painted finishes over time if not removed properly.
Side Paths
The narrow side paths, mostly shaded throughout the day, had accumulated a layer of organic grime and mild mould growth. These areas not only looked tired and dirty but were becoming increasingly slippery underfoot.
Paved BBQ Area
The paved BBQ area had lost its original colour due to a build-up of grime, natural dust, and general weathering. Being a high-traffic area used for entertaining, it needed a clean that not only restored its look but also made it safer and more welcoming underfoot.
Each of these areas required specific cleaning techniques based on the type of material and level of contamination—something Glason’s team is highly experienced in delivering.
Our Exterior Cleaning Process
To ensure a thorough and lasting result, we applied a multi-step cleaning process tailored to the specific surfaces and contaminants across the property.
- Detailed Site Inspection:
We began with a full inspection of the driveway, letterbox, paths, and courtyard. This allowed us to assess the surface types—primarily exposed aggregate and textured concrete—and identify the presence of lichen, grime, and mould. Understanding how these contaminants behave helped us determine the safest and most effective cleaning method for each area.
- Biocide Mould Pre-Treatment:
Before any pressure cleaning took place, we applied a commercial-grade biocide to all affected areas, especially the letterbox and driveway where lichen was present. This step is essential—it kills the growth at the root, making it easier to remove and helping to prevent regrowth over time.
- High-Pressure Surface Cleaning:
We used professional high-pressure equipment to lift and remove the dead lichen, ingrained grime, and embedded contaminants. Pressure settings were adjusted based on the surface to ensure a deep clean without causing damage. The aggregate and paved areas responded particularly well to this process, with a clear visual difference even after the first pass.
- Detail Work & Edging:
Once the main surfaces were treated, we cleaned edges, joins, and any remaining buildup in corners or along garden edges—areas that often get missed with DIY efforts. This attention to detail ensures a uniform result across the entire outdoor space. - Final Rinse and Inspection:
A low-pressure rinse removed any loosened debris, dead organic matter, and chemical residue. We finished with a final inspection to confirm the contaminants were fully removed and the surfaces were safely restored.
The Results of Our Exterior Pressure Cleaning
The transformation of this Springfield property was immediate and striking. What had once been weathered, patchy, and overrun with organic growth now looked clean, consistent, and well cared for.
Driveway
The driveway’s natural tone was restored, and all signs of lichen were removed. The surface no longer looked patchy or stained, and the overall brightness returned, significantly improving street appeal.
Letterbox
The letterbox, once mottled with light-green lichen, was fully cleaned back to its original brick finish. Removing the lichen not only restored its appearance but also protected the brickwork from further damage.
Side Paths
With the grime and mild mould removed, the side pathways now look refreshed and are no longer slippery—making them safer to walk on, especially after rain.
Paved BBQ Area
The BBQ area now looks sharp, warm, and ready for entertaining. Its colour has been revived, and it no longer feels neglected or dull.
The overall benefit extended far beyond appearance. The property now has increased visual appeal, improved safety underfoot, and longer-lasting surfaces thanks to the removal of contaminants that degrade materials over time.
