External mastic for homes and businesses in Ravenscraig
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with failed seals between different materials and weathered mastic that no longer stretches, we can help, on copings & trims, brickwork movement joints and render & cladding joints alike.
External sealant needs dry surfaces, so outdoor work around Ravenscraig is planned around the weather. Let us know about access to every wall and roofline.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, 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.
Common problems we fix in Ravenscraig
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
Historic houses such as Cambusnethan House, about 2.7 miles south, show how far back building around Ravenscraig goes.

Questions from Ravenscraig
Can you do external mastic in Ravenscraig?
Yes, Ravenscraig is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Shieldmuir station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In an older home around Ravenscraig, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

When it is not the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Damp that isn’t coming from the joint
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

Walls and rooflines in Ravenscraig
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. With historic houses such as Cambusnethan House (about 2.7 miles south) nearby, there’s older building stock in the area around Ravenscraig as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Shieldmuir station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Our Lady's High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take 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.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
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.
