The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Westerwood 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.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

How we handle external mastic in Westerwood
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. Typical jobs include cracked joints where brick meets render or frames and rigid filler in a joint that should flex, on brickwork movement joints, concrete & block and façade panels.
External sealant needs dry surfaces, so outdoor work around Westerwood is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

FAQs for Westerwood
Can you do external mastic in Westerwood?
Yes. Our work covers the whole of Scotland, and Westerwood is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Westerwood?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we will confirm what access is needed.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before any work starts.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
When to call us in Westerwood
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
For site and facilities teams at buildings such as Abronhill High School, its movement joints, gutters and trims need looking after like any other building’s.
Before booking anyone
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- Whether VAT is included
When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that isn’t coming from the joint
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Outside joints around Westerwood
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Cumbernauld station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before the bead.
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.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
For landlords and businesses
Housing providers, facilities teams and property managers book us too in Westerwood and across North Lanarkshire. We can quote a run of properties together.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
