External mastic in Skinflats
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you’re dealing with panel joints letting water in and hard, crazed mastic that has stopped moving, we can help.
External sealant needs dry surfaces, so outdoor work around Skinflats is planned around the weather. Let us know about access to every wall and roofline.
Each job carries a 12-month guarantee, large or small.

External mastic in Skinflats: local notes
Skinflats is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you let a flat or house near Falkirk Grahamston station, split movement joints are easy to miss on a rental until damp shows inside.

Aftercare tips
A little care helps the new joints last. Our advice:
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we have said otherwise
- Never let anyone fill a movement joint with mortar
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Landlord and commercial work in Skinflats
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Skinflats: your questions answered
I let a flat near Falkirk Grahamston station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Does living near the coast affect external mastic in Skinflats?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
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.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Skinflats, along with the rest of our area.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Around Skinflats, 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.
- We start by walking round the building and agreeing the joints and the access.
- 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.

Advice
What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- The type of sealant required
- Whether there’s mould to deal with
- Working hours on commercial sites
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What we need to know
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
What we’re called out for in Skinflats
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
The problems people usually mention when they call are:
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
Schools such as Graeme High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why it’s worth doing now in Skinflats
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
