Exterior cleaning in Ashmore is mostly about restraint. Plenty of the buildings are older than the pressure washer by a couple of centuries, and on those the honest answer is often a treatment left to work, or a gentle soft wash, not a clean with force.

On buildings like these in Ashmore the trouble sits in the gutters, underfoot and on the roof. Gutters and valleys that have filled with leaf litter off the surrounding woodland and are now running down the face of the wall. Paths, paving and steps that have gone green and genuinely slippery, which up on this ground lasts most of the year, not a few weeks. And a roof carrying enough moss that lumps of it are coming off into the gutter and down onto the path.

What we do about it is the same order every time. The site visit is free, and on a building of any age it is the important part: we look at the mortar, the state of the render and what the roof covering actually is before anybody talks about method.

Where a surface is doubtful we put a small test area somewhere out of sight and let you see how it behaves. Then you get a written itemised quote with the method named against each surface, including the surfaces we are recommending you leave alone and why.

The work

What can and cannot be cleaned on an old Ashmore building

Old roof coverings. There are twenty six entries on the national list in and around this village, and plenty of unlisted buildings of a similar age beside them. Where a roof is hand made clay tile or stone slate, no pressure goes near it at any setting.

Old clay is porous and softer than it looks, and a lance drives water under the lap, lifts tiles off their nibs and takes the weathered face off in strips. Moss is lifted off dry by hand and by scrape, the ridge is checked, never scrubbed, because the mortar under it is usually lime and already tired, and treatment is used sparingly. Lichen on old clay is a different question. It is slow, largely harmless and part of how the roof looks, so we will say when a roof clean is simply not worth buying.

Flint, soft brick and lime mortar. Where a wall is flint panels and lime rather than brickwork and cement, the joint is softer than the stone either side of it. Force does not clean that surface, it excavates it: mortar comes out of the joints, water is driven into the wall behind, and the damage does not show until the following winter. That work is a low pressure rinse and a brush, sometimes a treatment and nothing else. Limewashed and lime rendered elevations are the same argument, since the coating is meant to weather and wash off slowly.

Not everything in Ashmore is old. The later houses round the village carry concrete tile, pebbledash and painted masonry, and they get the ordinary handling: moss off dry, biocide on to kill the spore, and a soft wash at low pressure on the walls.

The gutters in Ashmore, many of them still cast iron, fill with leaf and seed off the trees as much as with moss, and clearing them is a separate job worth doing before any wall is washed. Old stone flags delaminate under force, so they get low pressure and a treatment for the black spot lichen, while block paving on the newer drives takes a wash and fresh kiln dried sand back into the joints. Anything shaded and sloping is done first, because that is where somebody actually slips.

How it runs

Cleaning old walls and roofs in Ashmore, gently

Older surfaces need a lighter touch: soft brick, flint, lime pointing and limewash all come off under a pressure washer. Thomas looks at each surface, tests how firm the growth and the face are, and prices it himself. Method, access and disposal are priced separately for each surface, which makes the written quote easy to hold against another. You keep one point of contact for the whole clean.

On a roof we scrape the moss off by hand and apply a biocide, never a jet wash. Walls are washed at low pressure, or given a soft wash and biocide, and paths and drives get what the surface can take. Where the run-off goes is on the quote, because it must not reach a drain or a watercourse, which is a pollution question. We park where the lane allows and leave the site clean. If a slipped tile or loose pointing turns up, you see a photo and a separate price.

Washing a wall is maintenance and needs nothing. Changing how it looks is another matter: taking off limewash or a historic finish, or putting a coating, paint or sealer on afterwards, can need listed building consent on a listed building. If a conservation area covers your house, which the council can confirm, appearance matters there too. The Planning Portal page on external walls sets out where the line falls.

Cost

What decides the price of a clean on older buildings

Age decides the price more than area does. A cottage with a hedge between the road and the wall, a farmhouse with a long low roof and no level ground for a tower, and a newer house you can pole from the drive are three different jobs before any water moves.

The surface. Soft brick, flint and lime need a low pressure or soft wash and more time. Modern block paving and concrete tiles can take more.

The growth. Heavy moss on a north facing roof is scraped off by hand, then treated with biocide, which keeps working for weeks. Lichen on stone is slow to go and should not be scrubbed off hard.

Access. Reach poles do part of it, the rest wants a tower, and the work at height rules decide which. Soft or sloping ground makes a tower slower to set up safely.

Water and run-off. A long hose run, and collecting the washings away from a drain, both add time to the job.

Ask what is treated and what is only rinsed, what pressure is used on soft brick or flint, whether a second visit is included, and where the run-off goes.

If there is a date

A sale, an inspection or a deadline to meet

Exterior cleaning is rarely urgent in the way a leak is. The deadline is usually a sale, an inspection or scaffold due to come down. Phone us with the real date instead of using the form.

Ashmore is 19.7 miles out, so village work is planned into a run of days, and we will say honestly if the weather on the Chase makes the date unrealistic. A biocide keeps working for weeks, so a roof treated late will still look green on the day. Scheduled cleans take place Monday to Friday, 8am to 6pm, and a call we miss is returned as soon as we can.

Worth knowing

The conservation area changes what a clean is allowed to do

Everything inside the Ashmore conservation area is looked at for how it affects the character of the place, and that includes the outside of buildings that are not listed themselves. For cleaning, the line is usually easy to find once somebody points at it. Taking dirt, moss and algae off a surface and leaving the surface as it was is maintenance, and nobody needs to be asked. Changing the surface is not.

Removing a limewash or an historic finish, taking the weathered face off old brick or stone, or following a clean with a coloured coating, a paint or a masonry sealer all change the appearance, and on a listed building that can need consent from Dorset Council in its own right. The number of listed entries around this village means the odds of that applying to you are far higher here than in a modern village down on the greensand.

What that should change for you as a buyer is what you ask for. Get the method in writing per surface, not a single line saying the house will be cleaned, and be wary of anyone who offers to clean and seal an old wall in the same breath, because a sealer on a solid lime built wall traps the water it is supposed to keep out.

Ask for a test panel somewhere nobody looks. And do not be talked into a full roof clean because the roof looks old: on hand made clay a good deal of what is being sold as dirt is weathering, and weathering is what has kept the tile alive.

Questions

Questions about exterior cleaning in Ashmore

Does the conservation area stop a straightforward wash?

Cleaning is maintenance, so Ashmore Conservation Area does not stop it. What the designation controls is appearance, and that bites the moment a wash turns into a change: a coating over old tiles, a fresh colour on render, a slate swapped for something modern. We keep what we do reversible. If you want the finish altered rather than simply cleaned, that is a conversation with Dorset Council before anyone starts.

Much of the village is old. Is jetting ever used?

Not on anything old up here. Ashmore has twenty six listed entries and a good deal of stone and lime mortar alongside them, and a lance drives water into an open joint and blows the binder straight out of it. We work at low pressure with a biocide and let it do the job over the following weeks, which is slower to watch but leaves the joints where they belong.

Ashmore is a long way out. Is that a problem?

It is roughly twenty miles up onto the Cranborne Chase, so we group work out that way and agree a booked date with you. The visit to price it is still free. In practice the lanes and the gateways matter more than the mileage, and Thomas checks where the van and the water can safely stand.

The lane is under trees. Does that change the clean?

It changes how soon the green comes back. Beech and hedgerow on the Chase keep the walls and roofs beside them shaded and damp, so a treated north face under trees in Ashmore will green over again sooner than an open one. Leaf in the runs and valleys is a gutter clearing job. The run off out here has nowhere to go except the verge and the ditch, so treatment is kept light and the debris is bagged.

What can I check myself before you visit?

Look at the wall below the gutter after heavy rain. A dark stripe down stone or render, or a green streak running from one joint, tells you where it is going over the front edge. Look along the ridge line too, and at the top of any chimney. On the older Ashmore properties growth on the north face is ordinary, but a slipped stone slate is not.
