External mastic for homes and businesses in Newarthill
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. Typical jobs include damp patches traced to an open external joint and joints where the bead has come unstuck, across copings & trims, render & cladding joints and concrete & block.
External sealant needs dry surfaces, so outdoor work around Newarthill is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Landlords, agents and businesses in Newarthill
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer

External mastic in Newarthill: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. With historic houses such as Cambusnethan House (about 4.3 miles south) nearby, there’s older building stock in the area around Newarthill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Cambusnethan House, about 4.3 miles south, is one of the historic houses in the wider area around Newarthill, and older homes nearby need a sealant that suits their walls. For landlords with property near Carfin station, split movement joints are easy to miss on a rental until damp shows inside.

Is Newarthill in your area for external mastic?

Do you have insurance?

Is it messy?
We keep the work tidy. We protect what’s around the joints.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we will say how long yours will take.
Where do you work from?
We work from Crawley. Our applicators cover Newarthill, along with the rest of our area.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Common problems we fix in Newarthill
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Panel joints letting water in
Schools such as Brannock High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
