Kilbeg External Mastic
Our applicators work in Kilbeg on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Failed sealant between panels on a façade
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
About our external mastic in Kilbeg
On houses, flats and commercial buildings across Kilbeg, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, copings & trims and joints between brick and frames, and the jobs we see most are rigid filler in a joint that should flex and movement joints with cracked, split or missing sealant.
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.
Each job carries a 12-month guarantee.

Why it’s worth doing now in Kilbeg
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Quotes for external mastic in Kilbeg
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The type of sealant required
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Photos by email are helpful but not essential. Try to tell us:
- Where the property is

- A few pictures by email, if you can
- How we’d reach the joints
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, drop us a line at info@mrmastic.co.uk.
Do you need external mastic in Kilbeg?
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall and make things worse.
The problems people normally mention when they call are:
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Cracked joints where brick meets render or frames
In the older streets around Sleat Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- The length of the guarantee
- Whether you can choose the colour
- Is the old sealant removed completely?
- What preparation is included
When something else is needed
To be straight with you, some problems need a different trade:
- Render that is blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
Surfaces we seal

Walls and rooflines in Kilbeg
Kilbeg is within about 1 mile of 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Around Kilbeg, as everywhere, external mastic is only as good as the preparation behind it.

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Around Kilbeg, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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 about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Kilbeg questions
Is Kilbeg in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Kilbeg is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Do you cover smaller places like Kilbeg?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Other services in Kilbeg
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
