About our external mastic in Brèibhig
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you are dealing with rain getting behind render or cladding at a joint and plants rooting in failed movement joints, we can help, on brickwork movement joints, joints between brick and frames and façade panels alike.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
Whatever the size of the job, it’s backed by our one-year guarantee in Brèibhig and across Na h-Eileanan Siar.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
What affects the quote in Brèibhig
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- What’s wrong with the joints now
- Any access issues, like height or stairs
- Roughly how big the job is
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.

When to call us in Brèibhig
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we’re asked about most:
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
If you look after a building such as Castlebay Community School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- How long to leave it before use
- How the surfaces are prepared before sealing
- How the colour is chosen
- Which sealant they’ll use, and why
When something else is needed
A few problems are outside what sealant work can do:
- Render that is blown, hollow or coming away
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Copings & trims
Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Outside joints around Brèibhig
Brèibhig 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Around Brèibhig, as everywhere, external mastic is only as good as the preparation behind it.

How do I get a quote for external mastic in Brèibhig?
Every job is different, so each one gets its own quote. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we do, step by step
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a place like Brèibhig, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about any water getting in
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit
