External & façade joints in Abronhill, North Lanarkshire
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Abronhill. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. For a place like Abronhill, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

About our external mastic in Abronhill
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. Common call-outs are for cracked joints where brick meets render or frames and sealant that has lost its bond to the brick or render, across render & cladding joints, copings & trims and joints between brick and frames.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in Abronhill
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 tears as soon as the joint widens.
Any of these means the joints need attention:
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
Letting a property close to Cumbernauld station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- What happens if the job turns out different
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- What product goes in the joint
Work for landlords, hotels and businesses
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.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Common questions in Abronhill
Do you cover smaller places like Abronhill?
Yes. Abronhill is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Abronhill in your area for external mastic?
Yes. We work across all of Scotland, and Abronhill is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch, so the joint stops doing its job. If it has already been filled, we can normally cut it out and reseal it.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
When something else is needed
Before booking, it’s worth knowing the limits:
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal
- Joints between brick and frames

What else we do in Abronhill
External mastic in Abronhill: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Schools such as Abronhill High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Whether there’s mould to deal with
- The number of rooms or windows
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- What’s wrong with the joints now
- A few photos by email, if you can
- The type of property
- The rough size of the job
We quote each job on its own, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details, and photos are welcome.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In an older home around Abronhill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.
