Repointing rubble stone and brick in West Lulworth

Deep irregular joints raked back to sound lime by hand, filled in lifts, and struck behind the face so the stone reads and the mortar does not.

On a West Lulworth rubble stone wall the mortar is not a line between units, it is most of what you see and all of what holds the wall together. It is due for repointing when it has gone sandy, stones are loosening, or damp shows inside after rain, and the job is raking back to sound material by hand and filling so the mortar finishes just behind the face of the stone, never proud of it. A wall that has bulged needs rebuilding first.

Walls in West Lulworth fail first on the seaward side, then at the faces and the old cement. Joints on the seaward side gone hollow, far enough through in places that you can see daylight in a boundary wall. Faces flaking off brick or stone near the ground, or up where water sits on the top of a wall. Or pointing put on at some stage in a hard grey mortar that now stands out from the stonework like piping on a cushion, with the stone behind it going soft.

None of that needs a wall taken down. The free site visit in West Lulworth is a survey, not a glance: we walk every elevation, scrape joints at the top and the bottom because they are rarely in the same condition, tap for anything hollow behind, and find out what the original mortar was before anybody talks about what replaces it. You get it back in writing, elevation by elevation, with the seaward and the sheltered faces priced separately, because on a house here they are almost never due at the same time. The visit and the itemised written quote are free.

The work

Pointing stone, and the brick that goes with it

Rubble stone is bedded in lime. Much of older West Lulworth is rubble stone with brick used at the quoins, over the window heads and in the chimneys, and every bit of it was bedded in lime because lime is the part that is meant to give.

Behind the face a West Lulworth wall is solid throughout, with no cavity anywhere in it. The beds in a rubble wall are deep, wide and irregular, so we rake by hand back to sound mortar rather than to a set depth, and neither a disc cutter nor an angle grinder goes near it. The joint is damped down and then filled in lifts, each one pressed in and left to take up before the next, because a deep void filled in one go shrinks, cracks and drops out inside a year.

The brick that runs through it. Quoins, window heads, arches and stacks in West Lulworth are brick, not stone, and they are usually laid in a finer mortar with a narrower joint. Pointing them at the width and the strength that suits the rubble around them loses the detail and reads badly from the road. We specify those separately and say so on the quote, usually an NHL lime or a lime putty gauged finer than the rubble mix, and struck to whatever profile the brickwork already carries: flush, recessed, weather struck or bucket handle.

Taking hard cement back off. Where somebody has pointed a West Lulworth wall in sand and cement the damage shows in the masonry rather than the joint. The wall cannot dry through a sealed joint, so it dries through the stone and the fired brick instead, and the face shells off. The tell is spalling faces under a joint that has gone crumbling and friable at its edges, and penetrating damp showing on the inside of the same wall. Cutting a cement joint out of soft rubble without taking stone with it is patient work with hand tools and it is priced on hours, not area.

Boundary walls, which take more than the house does. There are a great many of them in West Lulworth, and they are wet from both faces with no roof over them. The coping is what saves one, so a loose or missing coping stone gets rebedded before anything else, off a tower where the wall is low enough, and then both faces are pointed rather than the side you can see from the road. Half a wall pointed is a wall still taking water from behind.

Faces that have already blown. A West Lulworth brick that has lost its face comes out whole and a matched replacement goes in, sourced against a sample held on the wall. Filling the hollow with mortar leaves a patch that never matches and is out again in two winters. On stone it is the same principle: replace or turn the unit rather than model a new face in mortar.

Stacks. A West Lulworth stack takes weather from every side with nothing warming it, so its joints run years ahead of the walls below. Raking and repointing above the roof line, renewing the flaunching that beds the pots and making good the top courses is scaffold work and it is a priced line of its own rather than something added at the end.

How it runs

Repointing stone and brick in lime, done properly

Thomas comes out to West Lulworth and picks at a handful of joints to find out what the old mortar is and how far it has eroded, then prices the work himself. The written quote gives access, raking out, the mortar mix, the area of each elevation, any brick or stone to replace, and disposal their own lines.

West Lulworth walls this near the sea were mostly built in lime, and lime is what goes back in. Cement pointing on soft stone or brick keeps water in the face, and the next frost spalls it off. Soft stone is raked out by hand. Before the whole wall is done we point a small test panel, so you can judge the colour and finish. Chimneys and gables are worked from scaffold, garden walls from the ground. Fresh joints are protected from sun, wind and rain while they cure. Sheets go down, the ground is swept daily, and cracked stone or a loose lintel found along the way is photographed and priced before we touch it.

Putting back the same mortar and the same joint is upkeep and needs no application. On a listed building the mortar counts as part of the fabric, so listed building consent comes first. A change of colour or joint also matters if the house turns out to be in a conservation area, which is worth confirming with Dorset Council.

How far back the joints have gone. Shallow wear takes a light rake. Joints washed back deep on the south west face, where the weather off the sea hits hardest, need more raking out and packing before the finishing coat goes in.

What the mortar should be. Lime mortar is slower to mix, slower to lay and needs protecting for longer while it cures. It is the right choice on most older stone and brick here. Cement is quicker and cheaper, and the wrong choice on soft material.

The face of the wall. Spalled bricks and broken stone faces need cutting out and replacing, and matching them is part of the cost. Most old walls have some; Thomas tells you how many he can see.

Height and where the platform stands. A chimney stack or a gable takes scaffold. A boundary wall does not. Work at height rules make the platform a priced line, and the lanes decide where it can go.

Before choosing a firm, ask: what depth are the joints raked to, and by hand or disc? What mix, and was it matched to what is there? Are replacement bricks or stones counted in the figure?

If water is getting in

Please phone instead of using the form. If you miss us, we will call back as soon as we can. Open joints let driven rain reach the inside face of the wall, and on a chimney the water gets behind the flashings.

The first visit finds where it is getting in. If the weather is bad we sheet the worst area or point it temporarily, then price the whole elevation once the wall has dried enough to see what is sound. Tell us which side of the house the damp is on; here it is often the face toward the sea. Planned repointing runs Monday to Friday, 8am to 6pm.

Worth knowing

Why the joint has to finish behind the face of the stone

The commonest thing done wrong to a wall in this village is not the mix, it is the profile. Somebody butters mortar out across the face of the stones and trowels it flat, so the finished joint stands slightly proud with a hard edge to it.

It is quicker than filling a deep irregular joint properly and it looks tidy for about two years. Then it starts holding water on the top edge of every stone instead of shedding it, the bond behind it is thin because the joint was never filled to the back, and it comes away in sheets with the surface of the stone attached.

A rubble joint wants pressing in until the void is genuinely full, then taking back so it finishes a shade behind the face, with the stone reading as the surface of the wall and the mortar sitting quietly between. It sheds water, it lets the wall dry, and it is how the wall looked when it was built. There is a second reason to care about it here. In a conservation area a wall repointed as a proud grey band has visibly changed from the road, and that is the sort of change the designation exists to control. So if you are collecting quotes, ask what the finished profile will be and whether the mortar will sit proud, flush or back from the face. Anyone who has pointed rubble stone before will have an answer ready.

Questions

Questions about repointing in West Lulworth

The pointing on our cottage stands proud of the stone. Does that matter?

Pointing that stands proud of the stone does matter, and it is the fault to look for first on West Lulworth stone. A proud joint holds water on the top edge of each stone instead of letting it run off, and it is usually a sign the joint was buttered across the face instead of filled to the back.

It tends to come away in sheets and bring the surface of the stone with it. Taking it off and pointing back behind the face is the repair.

Should the seaward and the sheltered walls be done together?

Rarely: on a house here the south west face is normally a decade ahead of the sheltered side, so doing all four elevations at once usually means paying to point walls that did not need it. We price them separately and tell you which are genuinely due. Where the access covers more than one face anyway, it can be worth doing them together, and we will say so.

What lime goes into a stone wall this close to the water?

A natural hydraulic lime graded to sit under the strength of the stone, with the sand matched to what came out. The point is that the mortar has to be the escape route: salt and moisture come back out through a breathable joint and do nothing worse than leave a bloom you can brush off. A dense mix, or anything painted on to seal the wall, forces that out through the stone.

Will taking the old hard pointing out damage the stone?

Not if it is done with hand tools and time. That is exactly why no disc goes near a soft wall: a cutter follows a straight line and rubble does not, so it bites into the stone either side. We cut cement out with a chisel and a hacksaw blade, work in short lengths, and leave anything that would take stone with it until we can get behind it properly.

Does the conservation area stop us repointing?

No, it controls how the work looks, not whether you can do it. Putting the same mortar back with the same joint profile is upkeep and needs nothing from anybody. A different colour, a proud profile or a change of material on an elevation that reads from the road is a change of appearance. If your building is listed the mortar itself is covered and consent comes first.
