External mastic in Auchmithie, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We’re often asked to deal with old sealant gone brittle and cracked and plants rooting in failed movement joints, across copings & trims, brickwork movement joints and concrete & block.
In and around a place like Auchmithie, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
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.

How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Outdoor work around Auchmithie depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

What external mastic looks like in Auchmithie
Auchmithie 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 sound outside sealant is part of that.
Rented homes near Arbroath station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Auchmithie
Does the coastal weather in Auchmithie affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Auchmithie within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
How do you reach high-level joints?
Each building is different. Send us photos and a rough idea of the height, and we will confirm what access is needed.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- Movement that is more than a sealant joint can take
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Copings & trims
- Joints between brick and frames
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
Why it’s worth doing now in Auchmithie
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Auchmithie, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Signs you need external mastic in Auchmithie
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Panel joints letting water in
In the older streets around Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- Is the old sealant removed completely?
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
