Churchdown drives, specifically
One Churchdown drive is rarely one surface — and that's the whole problem.
Churchdown sits in the gap between Gloucester and Cheltenham, under the wooded bulk of Chosen Hill, and it grew up in pieces. There's the old Brookfield village core with its 1960s and 70s poured-concrete drives, the post-war estate streets laid in tarmac, and decades of later infill in block paving. Knock on three doors in a row and you'll find three different surfaces — and more often than not, a single drive that's a concrete apron at the garage running into block paving at the gate, with a strip of tired tarmac down one side.
That mix is exactly why so many Churchdown drives get cleaned badly. A contractor who only owns a pressure lance treats the whole lot the same: full pressure on the lot, zebra stripes across the block paving, the surface torn off the old concrete, and the chippings blown out of the tarmac into the border. It looks worse than when they started, and within a few weeks the sand has washed out of the block joints and the weeds are back. The surfaces are different, so the method has to be different — and that's the bit we get right.
The hill makes it all worse. Chosen Hill rises straight out of the village to 510 feet, its broadleaf-and-conifer flanks throwing long shade across the streets that climb it — Parton, the upper end of Pirton Lane, the slopes towards Chosen Hill itself. Drives on the shaded north and east side barely dry out from autumn to spring, and damp concrete, damp tarmac and damp block paving are all exactly what algae, moss and lichen colonise first. The same picture carries straight on into Innsworth, Hucclecote and Brockworth, which is why we're somewhere in GL3 most weeks of the year.
It's worth being clear about what each surface is actually suffering from, because the cure is different for each. The old poured concrete around Brookfield doesn't grow weeds — it goes black, with a film of algae and patches of lichen baked into the brushed texture, and the temptation to scour it off at full pressure is exactly what ruins it. The block paving doesn't really stain so much as lose its joints: the kiln-dried sand washes down over the years, the gaps open up, weeds and moss root in the bare joints, and the blocks start to rock. The tarmac just oxidises and greens — the bitumen fades grey in the sun and the shaded sections grow a slick of moss that's genuinely slippery underfoot. Treat all three as one job and you'll fix none of them properly; that's the trap most Churchdown drives have already been put through at least once.
