Carron External Mastic
Sealing brickwork movement joints, render, cladding and façade joints in Carron, with a 12-month guarantee on every job. Call for a quick quote.
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep high-pressure jets off the joints
- Tell anyone working on the walls about the movement joints
- Have failed joints looked at early
- Check external joints each spring
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
External mastic for homes and businesses in Carron
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and people most often call us about gaps where render, brick and frames meet and old sealant gone brittle and cracked.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.

What else we do in Carron
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a place like Carron, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What you get with us
- Sealant colour chosen to suit
- Tidy, careful work
- Sanitary silicone with an anti-fungal additive in wet areas
- We are fully insured
Do you need external mastic in Carron?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
Rented homes near Larbert station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before booking
- What the cure time is
- How much experience the applicator has
- Whether all the old sealant comes out first
- The length of the guarantee
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours to a few days, depending on the length of joint and the access. Around Carron, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common questions in Carron
Is Carron within the area you cover?
Yes. Carron is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is external mastic in a coastal place like Carron any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Walls and rooflines in Carron
Carron is within about 3 miles of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Falkirk High School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Stenhouse and Carron Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
