External Mastic in Beith
Our applicators work in Beith on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
How we handle external mastic in Beith
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint doesn’t stand out. If you have sealant that has lost its bond to the brick or render and movement joints filled with mortar instead of sealant, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job.

What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.

What external mastic looks like in Beith
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Homes close to Old Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Beith: your questions answered
Is Beith in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Beith is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
I let a flat near Glengarnock station. Can you help?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Why it’s worth doing now in Beith
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In an older home around Beith, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- Arbo and Everbuild products
- ARBOMaster approved applicator
- A sealant colour to suit the surroundings
- A 12-month guarantee on all work

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What we are called out for in Beith
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The problems people generally mention when they call are:
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
Letting a property close to Glengarnock station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether all the old sealant comes out first
- Who turns up on the day
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
