About our external mastic in Kennishead
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include weathered mastic that no longer stretches and sealant pulling away from one side of the joint, across joints between brick and frames, copings & trims and render & cladding joints.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Kennishead, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What we do, step by step
The work is kept neat and contained to the area we are working on. The job normally takes a few hours to a few days, depending on the length of joint and the access. Inside a flat in Kennishead, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Common questions in Kennishead
Who arranges sealant work on the shared parts of a tenement in Kennishead?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Can you do external mastic in Kennishead?
Yes, Kennishead is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Landlords, agents and businesses in Kennishead
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The type of sealant required
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
Doing several joints on one visit is normally more efficient than separate visits. We’ll send you a clear quote for the lot.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- The type of property
- Any previous sealing or DIY work
- Roughly how big the job is
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. When it suits you, send an email to info@mrmastic.co.uk.
Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Wind-driven rain gets into any failed joint on the outside of a city building, and in Kennishead, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Why us?
