Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How we handle external mastic in Coig Peighinnean
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you’re dealing with plants rooting in failed movement joints and rain getting behind render or cladding at a joint, we can help, whatever the surface.
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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal

Aftercare tips
To keep the joints looking good and working properly:
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Coig Peighinnean: your questions answered
Is Coig Peighinnean in your area for external mastic?
Yes. We work across all of Scotland, and Coig Peighinnean is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will you come out to Coig Peighinnean?
Yes, smaller places are covered as well as towns. 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.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Do you use backing rod?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Are you insured?
Yes. Full insurance covers our work.

Related advice
What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Outside joints around Coig Peighinnean
Coig Peighinnean 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. 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 site and facilities teams at buildings such as Lionel School, larger buildings have long runs of movement joint that eventually need resealing. In and around Coig Peighinnean, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
