Tongland External Mastic
Problem with your movement joints in Tongland? We cut out the old, prepare the joints and apply the right sealant.
- Plants rooting in failed movement joints
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
External mastic in Tongland, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you’re dealing with plants rooting in failed movement joints and rain getting behind render or cladding at a joint, we can help.
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.
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.

What affects the quote in Tongland
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- Any working-time requirements on site
- Whether there’s mould to deal with
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear price before work begins.
Helping us quote
When you call or email, it’s useful to know:
- How we’d reach the joints
- The address or postcode of the job
- Roughly how big the job is
- Pictures of the joints, sent by email

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Tongland, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere like Tongland may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Tongland buildings and the weather
Tongland 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Tongland Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Honest limits
A few problems are outside what sealant work can do:
- Movement that is more than a sealant joint can take
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
Joints and surfaces we work on
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
What happens if it’s left?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

FAQs for Tongland
Do you cover smaller places like Tongland?
Yes. Tongland is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Tongland in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Tongland is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
When to call us in Tongland
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
People generally contact us after spotting something like this:
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
Managing a site like Kirkcudbright Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Make sure movement joints are not pointed over
- Look over the joints every year, ideally after winter
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
