External Mastic in Glenelg
Movement joints in Glenelg need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
External mastic in Glenelg, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on brickwork movement joints, façade panels and joints between brick and frames, and the jobs we see most are hard, crazed mastic that has stopped moving and failed seals between different materials.
In and around a place like Glenelg, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Big or small, you get the same 12-month guarantee.

The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere like Glenelg may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Your questions about external mastic in Glenelg
Can you do external mastic in Glenelg?
Yes, Glenelg is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Will you come out to Glenelg?
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.
How long does external mastic last?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we will say how long yours will take.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Other services in Glenelg
For landlords and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Common problems we fix in Glenelg
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.
Most people get in touch when they notice one of these:
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Joints with sealant missing in places
For site and facilities teams at buildings such as Bernera School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- When the joint can take water or movement
- Whether VAT is included
- How hidden problems are handled
- Whether they’re fully insured
Why act early in Glenelg
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

- Quality sealants from Arbo and Everbuild
- A sealant colour to suit the surroundings
- Old sealant always removed completely
- Colour agreed with you before any work starts

External mastic in Glenelg: local notes
Glenelg 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. Glenelg is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Around Glenelg, as everywhere, external mastic is only as good as the preparation behind it.
