External mastic in Widewall
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. We work on copings & trims, brickwork movement joints and concrete & block, and common reasons people get in touch are weathered mastic that no longer stretches and failed sealant between panels on a façade.
In and around a place like Widewall, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
There’s a 12-month guarantee on every job.

Aftercare tips
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.

When to call us in Widewall
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
For jobs in and around Widewall, choosing the right material for each joint is as important as a tidy finish.

What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Around Widewall, 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Work for landlords, hotels and businesses
Landlords and letting agents in Widewall can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Housing providers, facilities teams and property managers book us too in Widewall and across the Orkney Islands. We can quote a run of properties together.
Widewall buildings and the weather
Widewall is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.
Around Widewall, as everywhere, external mastic is only as good as the preparation behind it.

Widewall: your questions answered
Is external mastic in a coastal place like Widewall any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Widewall within the area you cover?
Yes. Widewall is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Widewall, along with the rest of our area.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
