How we handle external mastic in Backlands
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. If you’re dealing with failed sealant between panels on a façade and plants rooting in failed movement joints, we can help, on façade panels, concrete & block and joints between brick and frames alike.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
- Ask before painting over external sealant
- Keep water from gutters off the wall
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

What external mastic looks like in Backlands
Backlands is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
For jobs in and around Backlands, choosing the right material for each joint is as important as a tidy finish. In and around Backlands, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Backlands questions
Does living near the coast affect external mastic in Backlands?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you cover Backlands for external mastic?
Yes, Backlands is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
How do I get a quote for external mastic in Backlands?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk and tell us what needs doing and where.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Landlords, agents and businesses in Backlands
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Backlands may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
Preparing for the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
