What we are called out for in Dunmore
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Look out for these signs:
- Joints with sealant missing in places
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Panel joints letting water in
If you look after a building such as Alloa Academy, larger buildings have long runs of movement joint that eventually need resealing.

External mastic for homes and businesses in Dunmore
On houses, flats and commercial buildings across Dunmore, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on brickwork movement joints, concrete & block and façade panels, and common reasons people get in touch are sealant pulling away from one side of the joint and plants rooting in failed movement joints.
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.
You get a one-year guarantee, the same in Dunmore as everywhere else we work.

Dunmore: your questions answered
Is Dunmore within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Alloa station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
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.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How we quote for external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- How many areas need sealing
- Working hours on commercial sites
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Any access issues, like height or stairs
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. 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.
- We look at every joint and agree a colour to suit the wall.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Related advice
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Render that is blown, hollow or coming away
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.
What we seal
- Brickwork movement joints
- Façade panels
- Copings & trims
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
Why act early in Dunmore
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 a place like Dunmore, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Walls and rooflines in Dunmore
Dunmore 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’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
In the older streets around Airth Parish Church and Churchyard, an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near Alloa station, outside joints that have cracked can let damp into a rental, so check them between lets.
