External & façade joints in Thornton, Fife
Our applicators work in Thornton on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
External mastic in Thornton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. Typical jobs include old sealant gone brittle and cracked and joints where the bead has come unstuck, on façade panels, concrete & block and brickwork 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.
All our work is covered by a one-year guarantee.

Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a place like Thornton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Outside joints around Thornton
Thornton 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 is 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 Old Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Glenrothes with Thornton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Looking after it afterwards
To keep the joints looking good and working properly:
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
- Check the sealant is paintable before painting near it
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Common questions in Thornton
Does the coastal weather in Thornton affect outside sealant?
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.
Will you come out to Thornton?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
When to call us in Thornton
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Look out for these signs:
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
If you look after a building such as Auchmuty High School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote

What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Around Thornton, 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 inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Advice
When it isn’t the sealant
We will not take on work that won’t last, so these are the limits:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
