About our external mastic in Carluke
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with sealant that has lost its bond to the brick or render and hard, crazed mastic that has stopped moving, we can help.
Harled walls are common in Scottish towns like Carluke, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Rooflines take their share of the weather as well.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Why it’s worth doing now in Carluke
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Scottish weather finds any gap, and in a town like Carluke, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

- A sealant colour to suit the surroundings
- Domestic, commercial and hotel work

External mastic in Carluke: local notes
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Historic houses like Cambusnethan House (about 4.6 miles west) are a reminder that the area around Carluke has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Carluke High School, its movement joints, gutters and trims need looking after like any other building’s. Cambusnethan House, about 4.6 miles west, is one of the historic houses in the wider area around Carluke.

When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that is blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer

Aftercare tips
A little care helps the new joints last. We recommend:
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Carluke questions
Is there a guarantee on external mastic in Carluke?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
I let a flat near Carluke station. Can you help?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.

What we are called out for in Carluke
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Water getting into walls through failed joints
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
Rented homes near Carluke station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- What insurance they hold
- Whether you can choose the colour
- How hidden problems are handled
- Which sealant they’ll use, and why
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
