How often should you clean your driveway or patio?
Most Teesside driveways and patios need professional cleaning every one to three years. Shaded, north-facing surfaces and coastal properties sit at the frequent end; sunny, south-facing block paving can stretch to four. A biocide treatment after cleaning, and sealing on block paving, are the two things that reliably stretch the gap.

The honest starting point
There is no single schedule, but there is a reliable pattern: every one to three years for most Teesside properties, decided by aspect more than anything else. A south-facing block-paved drive in Yarm that dries fast after rain might look decent for four years. A north-facing drive behind a 1930s semi in Acklam, shaded by the house all winter, can be green again within eighteen months of an untreated clean. The surface barely matters compared to how long it stays wet.
What sets your schedule
Aspect and shade
North and east-facing surfaces, and anything shaded by the house, trees or fences, stay damp longest and grow algae fastest. This is the single biggest factor, and on Teesside's damp air it is unforgiving. If your drive or patio is shaded through winter, budget for the frequent end of the schedule or for treatments that stretch it.
Distance from the sea
Coastal properties in Redcar, Seaton Carew and around Hartlepool's marina get salt spray that keeps surfaces moist and feeds algae year-round. Expect to clean on a shorter cycle than the same surface inland, or to lean harder on biocide and sealer.
Trees and planting
Overhanging trees drip, drop leaves that stain and rot into the joints, and shade the surface. A patio under a mature tree can need attention annually regardless of aspect. Autumn leaf clearing is free and genuinely extends the life of a clean.
Surface type
Block paving traps growth in its joints. Indian sandstone is porous and hosts black spot lichen. Concrete slabs sit in between. Porcelain is nearly non-porous and the slowest to colonise, though its joints still grow weeds. Imprinted concrete holds up well until its sealer wears, then it ages quickly.
Maintenance between professional cleans
Three cheap habits stretch every professional clean: sweep or blow leaves off before they rot in autumn; spot-treat algae films with a patio-safe biocide wash each spring rather than waiting for a full clean; and keep gutters and downpipes from overflowing onto the surface, since a constantly wet stripe of paving greens up first. None of this replaces a proper clean, but together it can turn a two-year cycle into a three-year one.
When sealing is worth it, and when it is not
Sealing block paving after cleaning and re-sanding costs roughly £5 to £8/m² on top of the clean, so £200 to £400 on a typical Teesside drive. What it buys: the jointing sand hardens and locks, weeds struggle to root, algae is slower to establish, oil sits on the surface longer before soaking in, and the blocks themselves weather more slowly, which matters near the coast.
Worth it: shaded drives that green up fast, block paving you have just paid to restore, and any drive where oil drips are a fact of life. Usually not worth it: tarmac and plain concrete, where sealers are cosmetic and short-lived; paving you plan to replace within a few years; and any drive where the ground underneath is moving, because no sealer fixes a sinking sub-base. If sealing is quoted, expect two coats on dry paving in a settled weather window, spring to autumn on Teesside, and expect it to want renewing every three to five years.
A sensible Teesside calendar
Spring: the classic full clean, winter growth off before the garden gets used. Early summer: sealing and decking oiling, when dry spells are reliable. Autumn: gutter clearing after leaf fall, algicide on slippery decking before the wet season, and leaves off the paving. Winter: soft washing still works in frost-free spells, and quotes are often keenest, but sealing and oiling wait for spring.
