How we handle external mastic in Tankerness
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have weeds or debris growing in open joints and panel joints letting water in, we can help.
In and around a place like Tankerness, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Whatever the size of the job, it’s backed by our 12-month guarantee in Tankerness and across the Orkney Islands.

FAQs for Tankerness
Is Tankerness in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Tankerness is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will you come out to Tankerness?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
How much does external mastic cost in Tankerness?
Size, access and the old material all affect the cost. Ask us for a quote.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
When to call us in Tankerness
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
- Water getting into walls through failed joints
Homes close to St Andrew's Burial-Ground include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What to look for in a quote
- What insurance they hold
- What happens if they find a problem under the old sealant
- How long to leave it before use
- Whether you can choose the colour
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Check external joints each spring
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building in most cases. Somewhere like Tankerness may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
How to get a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, email us at info@mrmastic.co.uk.

What else we do in Tankerness
Outside joints around Tankerness
Tankerness is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
In and around Tankerness, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a place like Tankerness, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
