Why exterior maintenance matters
Your home's exterior is its first line of defence against the elements. Rain, UV radiation, wind, humidity, salt air and organic growth, including moss, lichen, algae and mould, attack every surface continuously. Without regular maintenance, these forces cause slow but cumulative deterioration that compounds over time.
The good news is that exterior maintenance is both straightforward and cost-effective when done on a consistent schedule. Prevention is far less expensive than remediation.
The key areas to maintain
1. Exterior walls and cladding
Cladding accumulates dirt, algae, mould and biological growth over time. Regular washing, typically every 12 to 18 months, removes this growth before it becomes embedded or causes surface damage. For premium cladding systems, soft washing (low pressure with specialist solutions) is preferable to high-pressure washing, which can force water into joints and cause damage.
2. Roof
Roofs are a major investment and require specific attention. Moss, lichen and algae growth should be treated before they cause physical damage to tiles, iron or membrane roofing. A professional roof clean and treatment every two to three years is a reasonable starting point, though the frequency depends on your property's environment, shade and roof material.
3. Gutters and downpipes
Blocked gutters are one of the most common causes of preventable building damage. Water that overflows from gutters can enter wall cavities, damage fascia timber, erode foundations and cause damp issues inside the building. Gutters should be cleaned at least annually, more often if your property has overhanging trees. Downpipes should be checked for blockages and correct drainage direction.
4. Decks and hard surfaces
Timber decks require regular cleaning to prevent slippery algae and mould growth, and to maintain surface integrity. Driveways and paths also accumulate organic growth and grime. Regular cleaning keeps these surfaces safe, attractive and in good condition.
5. Window and door seals
Perished seals around windows, doors and penetrations are a common weathertightness risk. Inspect these annually and arrange resealing where required. This is one of the easiest and most cost-effective ways to prevent moisture intrusion.
6. Minor repairs
Visible cladding damage, fascia deterioration, missing or damaged flashing, and rust spots on metalwork should be attended to promptly. Left unaddressed, minor issues escalate into major repair bills. A proactive approach, catching and fixing small problems during routine maintenance visits, is the most cost-effective strategy.
The case for a scheduled maintenance plan
The most effective approach to exterior maintenance is a consistent, scheduled plan rather than ad hoc reactive bookings. A scheduled plan ensures nothing is missed, maintenance is completed at the right time of year, and your property is consistently protected.
The Prevent Plan is designed precisely for this purpose. We assess your property, build a tailored maintenance schedule, and manage all bookings on your behalf.
