Dartmouth’s “City of Lakes” environment creates a specific set of challenges for your home’s exterior. With high moisture levels from the harbour and numerous inland lakes, algae and mildew grow rapidly on siding, decks, and driveways. This organic growth isn’t just a cosmetic issue; it traps moisture, which can lead to wood rot and premature wear on masonry. Left untreated, these surfaces become slick and hazardous, especially during the humid spring and fall months.
The damp conditions that cause roof moss in neighbourhoods like Portland Estates, Crichton Park, and Manor Park also impact your hardscape surfaces. Areas with heavy tree canopies or north-facing walls rarely get enough sunlight to dry out, making them hotspots for moss and black algae streaks. Professional pressure washing is the most effective way to remove these layers and restore your property.
