Reliable fortnightly lawn mowing in Westerham from £25 per visit. Keltic Grounds is a family-run, fully insured grounds maintenance team covering Westerham, Brasted, Sundridge, Crockham Hill, and the surrounding TN16 villages
The blade goes up in summer heat, never scalped. In a Westerham summer on the exposed Greensand Ridge, lawns dry out faster than in the surrounding valleys — scalping is one of the quickest ways to stress already-dry grass. We mow to leave the lawn strong, not just short.
Every visit, not just the first. Clean edges are what separate a looked-after lawn from one that's just been mowed. We use proper edging shears, not a strimmer flail.
We collect every clipping and take it away. Your lawn isn't left with rows of cut grass to rot into thatch, and your patio isn't covered in green dust.
We blow down all hard surfaces after the cut — driveway, paths, patio, decking. The garden is left ready to use, not ready for sweeping.
Westerham sits on the Greensand Ridge, six miles north-west of Sevenoaks but meaningfully different in character. The town centre is higher, more exposed, and closer to the Surrey border — most lawns in TN16 sit on a mix of greensand and clay rather than the chalk-clay border you find around Sevenoaks proper. Greensand drains faster, dries out quicker in summer, and tends to be more acidic, which favours moss and sometimes encourages the wrong species of grass to dominate. We mow according to what's actually underneath, not just what's on top.Elevation matters more in Westerham than people realise. The town centre sits at around 180 metres above sea level — Sevenoaks central is closer to 100.
That's enough difference to push the spring start back by a week or two most years, and to bring frost into late April in cold seasons. We don't start the regular mowing run until the soil's properly warm, which the RHS recommends as around 6°C. In Westerham that's typically late March to mid-April, depending on the year.Wind exposure is the other thing that sets Westerham apart. Sitting on the ridge with the Downs to the north and open valley to the south means lawns here dry faster after rain than they do in Sevenoaks valley. That's mostly a good thing — we can often mow within hours of a shower where we'd have to wait a day in town — but it also means lawns can stress sooner in a dry summer. We raise the blade earlier in July and August on Westerham gardens than we would on lower-lying ones, and recommend leaving cuttings to mulch back during proper drought weeks rather than collecting them.Older Westerham properties — and there are plenty of them, especially around the Green and the village core — often have lawns that have been in place for decades. Mature lawns on greensand tend to develop thatch faster than younger ones on clay, and that thatch build-up is what causes most of the moss problems we see when we first visit a Westerham garden.
If your lawn feels spongy underfoot, looks more yellow-green than rich green, or has visible moss in spring, scarification is usually the answer.Like everywhere in West Kent, leatherjackets and chafer grubs are common, particularly in lawns that haven't been treated for a few seasons. If we spot signs — yellowing patches, soft turf, increased bird activity — we'll flag it during a visit and recommend treatment before it spreads.If you've inherited a tired lawn from a previous owner, or one that's never quite recovered from a thatchy build-up, we offer scarification, aeration, top-dressing and full lawn renovation as well as regular mowing. The same crew handles everything — we don't subcontract.
Transparent pricing. The figures below are starting points based on lawn size — every
garden is different, so we'll always confirm before the first visit.
We're based on the Sevenoaks/Orpington corridor and cover the full TN13, TN14, and TN15 postcode areas plus the surrounding villages. If you're nearby and not listed, ask — we may still be able to help.
