Half an hour up the Wye valley. Older property, softer materials, and the most careful work we do anywhere on the patch.
Older buildings need the gentlest method.
Lime mortar, soft local stone and slate do not tolerate pressure. Opening up a joint lets water into a wall that has been fine for two centuries.
If your property is listed or in the conservation area, say so when you enquire.
Up the A466 through the valley
Including Wyesham and the surrounding villages
On the older town-centre property
Stone, render and roof moss
JPM Exterior Cleaning is based in Tutshill, just outside Chepstow, and covers Monmouth and the surrounding area including Wyesham, Overmonnow, Redbrook, Llandogo, Tintern and St Briavels. We clean patios, driveways, block paving, render, gutters and roofs for homes and local businesses.
We are Checkatrade approved, AEM CPD certified and fully insured. Quotes across Monmouth are free and fixed before any work starts. Call 07947587517.
Why Monmouth is different is work
Monmouth sits where the Monnow joins the Wye, and much of the town centre is genuinely old. That changes almost everything about how a job is approached compared with an estate driveway in Caldicot.
Older walls here are bedded in lime, which is deliberately softer than the stone so the wall can move and breathe. Pressure strips it out, and once water is getting into the wall the problem is no longer cosmetic.
Slate resists growth better than concrete, but it gets brittle and the nails fatigue with age. The moss lodges in the laps and along the ridge rather than across the face.
The Monnow and the Wye both run through the town, and the low-lying parts hold damp well into spring. North-facing stone stays green for months.
Monmouth is not one kind of housing, and the job changes noticeably depending on where you are.
Painted render, soft stone and narrow access. Some of these properties have no vehicle access to the rear at all, which affects the price more than the area does.
This is the gentlest work we do. Everything is tested on a discreet area first.
A broader mix — some Victorian terracing, some post-war and later housing with concrete tile roofs and block paving. More conventional work than the centre.
Indian sandstone patios and modern render, the same as anywhere else built in the last twenty years. Indian sandstone cleaning →
Scattered, often older, and under heavy tree cover along the river. Gutters here fill quickly and roofs on shaded pitches carry a lot of moss.
Nothing costs more because of where you are. What changes is what the property needs.

Proof, not claims
Both frames from the same position in the same light. We do not put up a page about a place we have not actually worked in.
CONFIRM-19: one photographed local job before this page goes live
Monmouth is about thirty minutes up the valley, and we are there regularly rather than occasionally. There is no travel charge, but it is worth booking a little further ahead than for Chepstow itself.
If a neighbour wants work doing at the same time, say so when you get in touch — two jobs on one trip costs less than two separate visits, and it usually means a sooner date.

Common questions
We clean them, and we do it with low pressure and careful testing. What we do not do is anything that alters the fabric.
If a property is listed, check whether consent is needed before any treatment goes on historic stone. We will always flag it if we think that applies rather than pressing on.
No. Lime mortar is intentionally softer than the stone around it, and pressure strips it out of the joints. Once water is getting into the wall itself, the problem stops being cosmetic.
These walls get low pressure and the right chemistry. More on soft washing
Yes. Slate is far less porous, so it holds much less growth across the face — the moss tends to lodge in the laps and along the ridge instead.
It is also brittle with age, and Victorian slate often has nail fatigue. Careful handling matters more than pressure. Roof cleaning
Yes — Llandogo, Tintern, Redbrook, St Briavels and the rest of the valley are on the same round as Monmouth.
Tree cover along the river is heavy, so gutters there need looking at more often than most places we work.
A little further than for Chepstow, simply because it is thirty minutes each way and we group valley work together where we can.
