External & façade joints in Lamlash, North Ayrshire
External mastic for Lamlash and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Concrete & block
- Copings & trims

About our external mastic in Lamlash
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have rain getting behind render or cladding at a joint and movement joints with cracked, split or missing sealant, we can help, on brickwork movement joints, render & cladding joints and concrete & block alike.
External sealant needs dry surfaces, so outdoor work around Lamlash is planned around the weather. Tell us how to reach each wall, gutter and roofline.

Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way. Around Lamlash, water from a failed joint in an older stone home can soak into timber and plaster.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Outside jobs in Lamlash need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us if parking is tricky
- Clear the area around the work

Lamlash buildings and the weather
Lamlash is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Lamlash, as everywhere, external mastic is only as good as the preparation behind it. For site and facilities teams at buildings such as Arran High School, its movement joints, gutters and trims need looking after like any other building’s.

FAQs for Lamlash
Is external mastic in a coastal place like Lamlash any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Lamlash in your area for external mastic?
Yes, Lamlash is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Looking after it afterwards
After the cure time, these simple habits help:
- Wash walls gently around the sealant
- Ask before painting over external sealant
- Check external joints each spring
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
What affects the cost of external mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- Any mould that needs treating
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- How many joints, rooms or windows are involved
- The address or postcode of the job
- Any access issues, like height or stairs
