External & façade joints in Achiltibuie, Highland
External mastic for Achiltibuie, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- White, clear, grey or another colour, product permitting
- 20+ years of sealant experience

External mastic in Achiltibuie, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. If you’re dealing with joints pointed up with cement by mistake and weathered mastic that no longer stretches, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job, large or small.

What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
- Brickwork movement joints
- Façade panels
Signs you need external mastic in Achiltibuie
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The problems people generally mention when they call include:
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
Around Achiltibuie, as everywhere, external mastic is only as good as the preparation behind it.
What your quote should include
- Is VAT in the price?
- Who turns up on the day
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
Questions from Achiltibuie
Will you come out to Achiltibuie?
Yes. Achiltibuie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Achiltibuie affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What else we do in Achiltibuie
How it works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Achiltibuie need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts

Advice
Landlord and commercial work in Achiltibuie
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Walls and rooflines in Achiltibuie
Achiltibuie 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For jobs in and around Achiltibuie, choosing the right material for each joint is as important as a tidy finish.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Quotes for external mastic in Achiltibuie
We do not publish a price list. The quote depends on:
- How many areas need sealing
- Working hours on commercial sites
- How easy the joints are to reach
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work.
