External mastic in Broughton
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 have weathered mastic that no longer stretches and failed seals between different materials, we can put it right, on copings & trims, render & cladding joints and joints between brick and frames alike.
In and around a place like Broughton, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Big or small, you get the same one-year guarantee.

FAQs for Broughton
Is there a guarantee on external mastic in Broughton?

Do you cover smaller places like Broughton?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you work for landlords and businesses?

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Different surfaces, different methods
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.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What else we do in Broughton
Signs you need external mastic in Broughton
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
The problems people normally mention when they call include:
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
In the older streets around Broughton Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Broughton: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Broughton, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Act on the first splits you see
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
