Your Seasonal Exterior Cleaning Calendar: What to Clean and When

A thoughtful exterior cleaning checklist turns home maintenance from a scramble into a calm seasonal rhythm. Windows, gutters, patios, render, driveways, soffits and fascias all weather at different speeds, yet each affects how the whole property feels. By planning what to clean and when, you can keep the exterior bright, protect vulnerable surfaces and avoid discovering blocked gutters or green paving only when guests are due or heavy rain arrives.

An exterior cleaning checklist for the whole year

The best exterior cleaning checklist follows the seasons. Spring is for lifting winter grime and preparing outdoor spaces. Summer is for maintaining glass, patios and garden-facing areas while the home is in full use. Autumn is for leaves, gutters and drainage. Winter is for prevention, watching for overflow, damp staining and slippery surfaces.

Not every task needs doing every month. Regular window cleaning might run every four to eight weeks, while gutters may need one or two scheduled clears a year. Patios and driveways often benefit from annual jet washing, with extra attention where shade or tree cover causes algae. Render and roof staining may be handled through soft washing when organic growth becomes visible.

The aim is to create a cycle that suits your home's setting, not a generic list that ignores exposure.

Spring: reset the exterior after winter

Spring is the season of renewal, and the exterior usually needs it. Rain, wind, moss, algae and grime can leave surfaces looking muted after winter. Start with the windows. Pure water window cleaning removes dirt from glass, frames and sills, leaving a spotless, streak-free finish without chemicals.

Next, look at patios, paths and driveways. If paving has turned green or slippery, professional jet washing can restore colour and improve grip. For block paving, fresh kiln-dried sand should be brushed back into the joints afterwards.

Spring is also a good time to inspect render, painted masonry and roofline details. If walls are green with algae or mildew, soft washing may be the right answer. If white uPVC has gone grey, green or yellow, soffit and fascia cleaning can restore a clean, even white.

Spring checklist

• Clean windows, frames and sills
• Jet wash patios and paths before outdoor furniture returns
• Check driveways for algae, tyre marks and moss
• Inspect render for green or black staining
• Clean soffits, fascias and uPVC frames where needed
• Check gutters for winter debris

Summer: maintain the areas you use most

Summer is when the exterior becomes part of daily life. Garden doors stay open, patios host meals, and windows are seen in stronger light. Fingerprints, dust, pollen and garden debris become more noticeable.

Regular window cleaning is particularly valuable in summer because bright sun reveals smears and haze. Pure water cleaning keeps glass, frames and sills fresh without chemical residue. Patio areas may need sweeping between professional cleans, especially after barbecues, plant watering or heavy use.

Soft washing may also be helpful in summer if shaded render or painted walls have greened over. Treating algae and mildew at the source helps surfaces stay clear for longer than pressure washing alone.

Summer checklist

• Keep windows on a four to eight week rhythm
• Sweep patios and remove fallen petals or berries promptly
• Watch shaded walls for algae
• Rinse garden furniture feet and pot bases to prevent staining
• Check drains after storms
• Arrange soft washing for render or walls before staining spreads

Autumn: prepare for rain, leaves and blocked gutters

Autumn is the most important season for gutters. Leaves, moss and roof debris can gather quickly, especially on homes near mature trees. Blocked gutters may overflow during heavy rain, staining walls, windows, fascias and render.

Ladder-free gutter clearing using a high-suction SkyVac system is a practical way to remove debris from the ground. Willow Alexander clears the whole run in one pass, fully insured, helping rainwater move properly before winter.

Autumn is also a good time to clear patios and driveways of leaf matter. Wet leaves can stain paving and encourage algae. If a driveway is already slippery, arrange jet washing before colder weather makes the surface more unpleasant.

Autumn checklist

• Clear gutters after leaf fall or before heavy rain
• Check downpipes for blockages
• Remove leaves from patios, paths and driveways
• Inspect roof moss and black streaks
• Clean fascias affected by overflow
• Book jet washing if surfaces are slippery

Winter: prevent small problems becoming larger ones

Winter exterior care is about vigilance. You may not be spending as much time outside, but rainwater, wind and damp are testing the building. Watch how water moves during heavy rain. Gutters should run cleanly into downpipes, not spill over the edge. Paving should drain rather than hold standing water for long periods.

Windows can still be cleaned in winter. In fact, regular cleaning prevents grime from building up and keeps interiors brighter during shorter days. Light rain should not spoil a pure water clean because the glass has been rinsed with deionised water that dries clear.

Avoid letting winter become a blank space in your maintenance calendar. A small intervention now can prevent staining and heavier work in spring.

Winter checklist

• Observe gutters during rain
• Check for damp staining beneath rooflines
• Keep windows clean for better winter light
• Watch for slippery algae on paths and steps
• Note render or roof staining for spring soft washing
• Keep drains and gullies clear of debris

How often should windows, gutters and hard surfaces be cleaned?

Windows are the most regular task. Many London and Kent homes benefit from professional cleaning every four to eight weeks. Busy roads, large glazing and exposed elevations often require a shorter interval.

Gutters usually need clearing once or twice a year, with autumn being the key moment. Homes beneath trees or with heavy roof moss may need more frequent attention.

Patios and driveways often benefit from annual jet washing, usually in spring. Shaded or heavily used areas may need a second clean or targeted attention. Render, painted masonry and roofs should be soft washed when algae, lichen or mildew becomes visible, rather than on an unnecessarily fixed schedule.

Why different surfaces need different methods

A good exterior cleaning checklist should not treat every surface the same. Glass needs pure water. Gutters need suction clearing. Render and softer materials need low-pressure soft washing with plant-safe biocides. Hard surfaces such as driveways, paths and patios can often be jet washed, with pressure matched to the surface.

Using the wrong method can cause damage or short-lived results. Pressure washing render may strip the finish. Ignoring gutter blockages can undo fresh window cleaning. Jet washing block paving without re-sanding leaves the job unfinished.

The right method protects the material as well as improving appearance.

A calm routine for a well-kept exterior

The value of an exterior cleaning checklist is not just organisation. It helps you see the home as a connected system. Roof moss affects gutters. Gutters affect walls and fascias. Trees affect patios and windows. Clean glass changes the feel of rooms inside. When each task is placed in the right season, maintenance feels less reactive and the property stays consistently cared for.
