External mastic for homes and businesses in Dingwall
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We work on brickwork movement joints, render & cladding joints and façade panels, and people most often call us about joints with sealant missing in places and old sealant gone brittle and cracked.
External sealant needs dry surfaces, so outdoor work around Dingwall is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Dingwall
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
People normally contact us when they notice something like this:
- Joints where the bead has come unstuck
- Failed seals between different materials
- Joints with sealant missing in places
- Panel joints letting water in
If you look after a building such as Dingwall Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Landlords, agents and businesses in Dingwall
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. Around Dingwall, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

External mastic in Dingwall: local notes
Dingwall is within about 1 mile of 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. Dingwall is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
For an older house near a landmark such as St Lawrence's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Dingwall station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Dingwall: your questions answered
Do you cover smaller places like Dingwall?
Yes, Dingwall is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is external mastic in a coastal place like Dingwall any different?
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. Walls facing the sea are generally the first to need attention.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we’ve said otherwise
- Clear growth from the base of walls and joints
- Point out the joints to other trades
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
