External mastic for homes and businesses in Morningside
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you have movement joints filled with mortar instead of sealant and rain getting behind render or cladding at a joint, we can put it right.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Morningside, access is planned first, and shared parts may need the other owners to agree.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Signs you need external mastic in Morningside
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Common reasons people contact us are:
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
If you live in an older home near St Matthew's Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Which colour the sealant will be
- What happens if the job turns out different
- The length of the guarantee
- Whether VAT is included
What affects the quote in Morningside
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- The type of sealant required
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- If someone has resealed it before
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
If you are in Morningside and need external mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and you’ll get a clear quote before work begins.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours to a few days, depending on the length of joint and the access. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Morningside, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Tell us about any water getting in
How to get a quote

Why it’s worth doing now in Morningside
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a tenement flat in Morningside, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

- Anti-fungal sanitary silicone in wet areas
- We agree the colour with you first
- Full insurance on every job

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.

How long before the joint can be used?

Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Morningside buildings and the weather
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. The title deeds set out which parts are common. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Slateford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Iain Tomlin School of Music, larger buildings have long runs of movement joint that eventually need resealing.
