Cheltenham drives, specifically
Why Cheltenham drives need a gentler hand than most.
Cheltenham isn't a one-surface town. Drive through Montpellier, Lansdown and Pittville and you're looking at gravel carriage drives sweeping up to Regency villas, with natural stone aprons and setts that were laid before anyone owned a pressure washer. Push out to Up Hatherley and Warden Hill and it's suburban block paving and imprinted concrete from the eighties and nineties. The mistake most cleaners make is treating all of it the same — turning up with one lance and one pressure setting and blasting whatever's in front of them. On a period drive that's how you scatter shingle into the borders and pit soft limestone for good.
The town's setting makes the cleaning more about damp than dirt. Cheltenham sits in a basin with the Cotswold escarpment to the north and east, and the affluent plots below Cleeve Hill and through Prestbury sit under heavy tree canopy. A drive that barely sees the sun stays damp for weeks, and permanent damp is what algae and moss colonise. So the calls we get from the smarter roads are rarely "it's filthy" — they're "it's gone green and slippery under the trees," or "the stone's tide-marked," or "the sealer we had done five years ago has gone patchy." Different problem, different fix.
Then there's the natural stone itself. The period villas around Montpellier, Tivoli and Bayshill often have Cotswold limestone or York stone at the front, and that stone is porous and soft. Greening and tide-marking sit in the surface, and the temptation is to blast it off — but high pressure opens the stone up so it soaks in more dirt next time and looks worse in two years. We treat stone with low pressure and a soft biological wash so the growth lifts without scarring the surface. The whole job, on a Cheltenham period drive, is restoring it sympathetically — getting it back to how it should look without leaving it raw.
The other recurring call is the previously-sealed drive that's gone wrong. A lot of the higher-value drives around Lansdown, The Park and Charlton Kings were sealed years ago, and a cheap or badly-timed sealer breaks down — it goes patchy, milky, or flakes off in sheets and traps dirt underneath. That's a strip-and-reseal job, not a quick wash, and we'll always tell you which one you're actually looking at rather than putting a fresh coat over a failing one. It's the difference between a drive that looks finished and one that looks worse a year later.
