Do you need external mastic in Kilmuir?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch after spotting one of these:
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
If you let a flat or house near Invergordon station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Which colour the sealant will be
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
External mastic for homes and businesses in Kilmuir
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’ll confirm what’s needed to reach them safely. We work on brickwork movement joints, joints between brick and frames and façade panels, and the jobs we see most are water getting into walls through failed joints and hard, crazed mastic that has stopped moving.
In and around a place like Kilmuir, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about parking restrictions
- Clear the area around the work
- Tell us about any water getting in

Advice
Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. 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.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Walls and rooflines in Kilmuir
Kilmuir is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Homes close to Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Kilmuir: your questions answered
Does living near the coast affect external mastic in Kilmuir?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Kilmuir?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Movement that’s more than a sealant joint can take
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
