How we handle external mastic in Eòlaigearraidh
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on copings & trims, concrete & block and render & cladding joints, and the jobs we see most are movement joints with cracked, split or missing sealant and water getting into walls through failed joints.
Outside joints can only be sealed when they’re dry, so work in Eòlaigearraidh depends on the weather. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Movement that’s more than a sealant joint can take
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints

- Concrete & block

Common questions in Eòlaigearraidh
Do you cover smaller places like Eòlaigearraidh?
Yes. Eòlaigearraidh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Eòlaigearraidh affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Why it’s worth doing now in Eòlaigearraidh
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Around Eòlaigearraidh, water from a failed joint in an older stone home can soak into timber and plaster.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away.

Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Ask before painting over external sealant
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
External mastic in Eòlaigearraidh: local notes
Eòlaigearraidh is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Whether the job is in Eòlaigearraidh itself or nearby, the right material for each joint matters as much as a neat finish. In and around Eòlaigearraidh, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Eòlaigearraidh (Gaelic: Eoligarry) is in Na h-Eileanan Siar. From the centre of Eòlaigearraidh to the outskirts, external mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Our area takes in 87 places across Na h-Eileanan Siar, large and small.
