External Mastic in Pinwherry
We cover Pinwherry for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
What we are called out for in Pinwherry
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
Letting a property close to Barrhill station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before booking
- How much experience the applicator has
- Whether all the old sealant comes out first
- What product goes in the joint
- The length of the guarantee
External mastic for homes and businesses in Pinwherry
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. Typical jobs include old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, across render & cladding joints, joints between brick and frames and copings & trims.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
Every job comes with our 12-month guarantee.

What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Somewhere like Pinwherry may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What external mastic looks like in Pinwherry
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
Around Pinwherry, as everywhere, external mastic is only as good as the preparation behind it.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
FAQs for Pinwherry
Can you help a landlord with a rental near Barrhill station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you cover Pinwherry for external mastic?
Yes, Pinwherry is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
Do you have insurance?
Yes. Full insurance covers our work.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk.

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
