When something else is needed

- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.

About our external mastic in Auchtertyre
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on brickwork movement joints, copings & trims and concrete & block, and common reasons people get in touch are water getting into walls through failed joints and failed seals between different materials.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Our work is backed for twelve months, in Auchtertyre and everywhere else we cover.

Why act early in Auchtertyre
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we’ll talk you through it.

Different surfaces, different methods
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap.
Questions from Auchtertyre
I let a flat near Duncraig station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Is Auchtertyre within the area you cover?
Yes, Auchtertyre is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
What information do you need?
Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Outside joints around Auchtertyre
Auchtertyre is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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 an older house near a landmark such as Lochalsh Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When to call us in Auchtertyre
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
It’s worth asking for a quote if you see:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
Rented homes near Duncraig station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
