About our external mastic in Forbes
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on joints between brick and frames, brickwork movement joints and copings & trims, and people most often call us about movement joints with cracked, split or missing sealant and moss and dirt in joints with no sealant left.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Forbes questions
Do you cover smaller places like Forbes?
Yes, Forbes is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Forbes for external mastic?
Yes. We work across all of Scotland, and Forbes is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How do I get a quote for external mastic in Forbes?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Why it’s worth doing now in Forbes
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- We agree the colour with you first
- Anti-fungal sanitary silicone in wet areas
- More than 20 years in sealant work
- Domestic, commercial and hotel work

Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Around Forbes, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Related advice
Common problems we fix in Forbes
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Common reasons people contact us include:
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
Managing a site like Alford Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Outside joints around Forbes
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Alford Parish West Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
