External Mastic in Birkhill
Movement joints in Birkhill need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
- Panel joints letting water in
How we handle external mastic in Birkhill
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have cracked joints where brick meets render or frames and hard, crazed mastic that has stopped moving, we can help, on façade panels, render & cladding joints and concrete & block alike.
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 our work is covered by a 12-month guarantee, wherever you are in Dundee.

What external mastic looks like in Birkhill
Historic houses like Camperdown House (about 1 mile south-east) are a reminder that the area around Birkhill has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Historic houses such as Camperdown House, about 1 mile south-east, show how far back building around Birkhill goes, and older homes nearby need a sealant that suits their walls. Schools such as Lawside Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

What we can’t put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
Surfaces we seal
- Render & cladding joints
- Façade panels
- Copings & trims
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Birkhill questions
Will you come out to Birkhill?
Yes, Birkhill is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Invergowrie 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.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Will the new joint stand out?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
What sealant do you use?
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.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.

Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
What we’re called out for in Birkhill
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Keep an eye out for any of the following:
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Panel joints letting water in
Letting a property close to Invergowrie station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Comparing quotes

- How the surfaces are prepared before sealing
- Which colour the sealant will be
- When the joint can take water or movement
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
