How we handle external mastic in Muirkirk
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on concrete & block, brickwork movement joints and copings & trims, and people most often call us about damp patches traced to an open external joint and leaking joints around cladding and façade panels.
Outside joints can only be sealed when they’re dry, so work in Muirkirk depends on the weather. Let us know about access to every wall and roofline.
Every job comes with our one-year guarantee, wherever you are in East Ayrshire.

Muirkirk questions
Is there a guarantee on external mastic in Muirkirk?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Muirkirk?
Yes, Muirkirk is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for property managers and facilities teams in Muirkirk and across East Ayrshire. Several sites can go on one quote, and we are fully insured.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Act on the first splits you see
- Ask before painting over external sealant
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
External mastic in Muirkirk: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For an older house near a landmark such as Muirkirk Old Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Around Muirkirk, as everywhere, external mastic is only as good as the preparation behind it.

Honest limits
We will not take on work that will not last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Render that’s blown, hollow or coming away
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
Also in Muirkirk
Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a place like Muirkirk, longer drives are planned in advance. 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.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
