Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
About our external mastic in Leith
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. Common call-outs are for sealant pulling away from one side of the joint and joints with sealant missing in places, on façade panels, concrete & block and copings & trims.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Leith, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access. Inside a flat in Leith, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.

How to prepare
- Let us know about earlier repairs to the joints

What external mastic looks like in Leith
Leith is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Leith School of Art, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Ninians Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Leith is about 3 miles north-east of Edinburgh, in Edinburgh. Jobs in Leith get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Leith is one of 175 places in Edinburgh where we work.
Jobs for external mastic in EH6, EH5 and EH1 works the same way as everywhere else we cover. You will find streets such as Fyfe Lane, Haig Lane and Mill Lane. Close by, we work in Timber Bush (1 mile south), North Leith (1 mile south-west), Bonnington (1 mile south-west), Newhaven (1 mile west) and Victoria Park (1 mile west). Within a short drive, we also cover Edinburgh (3 miles south-west), West End (3 miles south-west), West Coates (3 miles south-west), Sciennes (3 miles south), Merchiston (3 miles south-west) and Newington (3 miles south). As one of the bigger places in Edinburgh, Leith has every kind of property, from flats to offices.

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. For landlords in Leith, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Your questions about external mastic in Leith
Is external mastic in a coastal place like Leith any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Edinburgh Waverley station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Where do you work from?
We work from Crawley. We cover Leith and the rest of Edinburgh, along with the rest of our area.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.

Do you need external mastic in Leith?
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The most common problems we see are:
- Plants rooting in failed movement joints
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Failed seals between different materials
Rented homes near Edinburgh Waverley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether they seal over old material or remove it
- Who turns up on the day
- What insurance they hold
- How the colour is chosen
