External Mastic in Fettercairn
Our applicators work in Fettercairn on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
How we handle external mastic in Fettercairn
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. We work on concrete & block, brickwork movement joints and copings & trims, and people most often call us about rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
All of our work is guaranteed for twelve months, in Fettercairn and everywhere else we cover.

Do you need external mastic in Fettercairn?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
The problems people normally mention when they call include:
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
Homes close to Fettercairn Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Outside jobs in Fettercairn 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 start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Walls and rooflines in Fettercairn
Harled (roughcast) walls are common in Scotland, 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 failed outside joints work against that.
Letting a property close to Laurencekirk station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

FAQs for Fettercairn
Do you work for landlords with property near Laurencekirk station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Fettercairn?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a place like Fettercairn, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
