Your questions about external mastic in Glencoe
Do you cover Glencoe for external mastic?
Yes, Glencoe is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Glencoe?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Should I point up the gap in my brickwork?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
How we handle external mastic in Glencoe
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. Common call-outs are for brick movement joints where the sealant has split and water getting into walls through failed joints, on copings & trims, render & cladding joints and façade panels.
In and around a place like Glencoe, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

If you manage several properties in or around Glencoe, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Never let anyone fill a movement joint with mortar
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
Don’t 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.
Quotes for external mastic in Glencoe
There’s no set price list, because jobs vary so much. What we look at:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Access and height
- Whether there’s mould to deal with
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
What to tell us for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Any previous sealing or DIY work
- The rough size of the job
For a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before we start.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It generally takes anything from a few hours to several days, depending on the building. Outside jobs in Glencoe need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at every joint and agree a colour to suit the wall.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Move anything stored near the joints

Glencoe buildings and the weather
Glencoe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
In and around Glencoe, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Glencoe is in Highland. We provide external mastic to homes and businesses in Glencoe. Glencoe is one of 253 places in Highland where we work. There’s also a page for Glasgow, about 65 miles away.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a place like Glencoe, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

When to call us in Glencoe
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Common reasons people contact us are:
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
For an older house near a landmark such as Episcopal Church Of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before you book anyone
- Are they insured?
- Whether VAT is included
- Whether the sealant suits the joint
- Is the old sealant removed completely?
