External & façade joints in Gulberwick, Shetland Islands
Problem with your movement joints in Gulberwick? We remove the old material, prepare the joints and seal them properly.
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
External mastic in Gulberwick, done properly
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. If you’re dealing with movement joints with cracked, split or missing sealant and failed sealant between panels on a façade, we can put it right, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Damp that is not coming from the joint
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

What external mastic looks like in Gulberwick
Gulberwick 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
In and around Gulberwick, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Your questions about external mastic in Gulberwick
Will you come out to Gulberwick?
Yes. Gulberwick 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. Let us know about access, parking and anything unusual about getting there when you book.
Is Gulberwick in your area for external mastic?
Yes. We work across all of Scotland, and Gulberwick is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Why do you put foam in the joint first?
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.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start, matched as closely as the range allows.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the building. Outdoor work around Gulberwick depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Gulberwick
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People generally contact us after spotting one of these:
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
For an older house near a landmark such as Gulberwick Mission Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before booking anyone
- Which colour the sealant will be
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- The size of the job
- Any working-time requirements on site
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- The type of property
- The address or postcode of the job
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Why it’s worth doing now in Gulberwick
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a place like Gulberwick, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.
Why choose Mr Mastic in Gulberwick
- White, clear, grey or coloured to suit, where the product allows
- Fully insured
- Tidy, careful work
- 20+ years of sealant experience
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
