External Mastic in Scarinish
Professional external mastic in and around Scarinish, with every bit of old sealant taken out first.
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.
What we seal
- Joints between brick and frames
- Copings & trims
- Façade panels
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
External mastic in Scarinish, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We work on façade panels, concrete & block and brickwork movement joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and plants rooting in failed movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.

Surface by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.

External mastic in Scarinish: local notes
Scarinish 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Scarinish, as everywhere, external mastic is only as good as the preparation behind it.

How the visit works
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. Somewhere like Scarinish may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Related advice
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Quotes for external mastic in Scarinish
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- The old material and how stubborn it is
- How easy the joints are to reach
- The amount of work
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- If someone has resealed it before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, drop us a line at info@mrmastic.co.uk.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What we are called out for in Scarinish
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Joints with sealant missing in places
- Failed seals between different materials
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
For an older house near a landmark such as Kirkapol Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Scarinish
Will you come out to Scarinish?
Yes, Scarinish is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Scarinish for external mastic?
Yes. Our work covers the whole of Scotland, and Scarinish is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint does not draw the eye.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We’ll reseal it with a flexible sealant.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
