Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

External mastic in Birchburn, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We are often asked to deal with plants rooting in failed movement joints and gaps where render, brick and frames meet, on brickwork movement joints, concrete & block and façade panels.
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.
You get a one-year guarantee, the same in Birchburn as everywhere else we work.

What external mastic looks like in Birchburn
Birchburn 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. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
If you live in an older home near St Molios Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Common questions in Birchburn
Do you cover Birchburn for external mastic?
Yes. We work across all of Scotland, and Birchburn is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Birchburn?
Yes. Birchburn is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes, we are fully insured.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Do you guarantee your work?
Yes. Every job comes with our 12-month guarantee.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Do you need external mastic in Birchburn?
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Panel joints letting water in
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
Around Birchburn, as everywhere, external mastic is only as good as the preparation behind it.
