External mastic for homes and businesses in Coylumbridge
A movement joint is a deliberate break that lets a wall expand and contract. 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 brickwork movement joints, copings & trims and render & cladding joints, and the jobs we see most are damp patches traced to an open external joint and movement joints filled with mortar instead of sealant.
Outside joints can only be sealed when they’re dry, so work in Coylumbridge depends on the weather. Let us know about access to every wall and roofline.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. For a place like Coylumbridge, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Coylumbridge buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Coylumbridge, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Coylumbridge is about 26 miles south-east of Inverness, in Highland. Every kind of property in Coylumbridge can book us for external mastic. The work is guaranteed for a year. Our area takes in 253 places across Highland, large and small. Dundee is on our list too, around 57 miles away.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What affects the quote in Coylumbridge
We don’t publish a price list. What we look at:
- The size of the job
- When we can work, for business premises
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- A few pictures by email, if you can
- If someone has resealed it before
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
We do not publish a price list. Instead, we send you a clear quote for your job. To arrange one, email us at info@mrmastic.co.uk.
When to call us in Coylumbridge
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
The most common problems we see are:
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Panel joints letting water in
For landlords with property near Aviemore station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Which sealant they’ll use, and why
- What insurance they hold
- The length of the guarantee
- Whether you can choose the colour
Coylumbridge: your questions answered
Is Coylumbridge within the area you cover?
Yes. Coylumbridge is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Coylumbridge?
Yes, Coylumbridge is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
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 long does external mastic take?
That depends on how much there is to do, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Highland.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
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.
