About our external mastic in Wilsontown
For buildings in Wilsontown, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on joints between brick and frames, façade panels and copings & trims, and common reasons people get in touch are hard, crazed mastic that has stopped moving and joints with sealant missing in places.
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.
Our work is backed for twelve months, in Wilsontown and everywhere else we cover.

Honest limits
To be straight with you, some problems need a different trade:
- Render that is blown, hollow or coming away
- Movement that is more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure movement joints aren’t pointed over
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Outside joints around Wilsontown
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.
Around Wilsontown, as everywhere, external mastic is only as good as the preparation behind it. For landlords with property near Breich station, split movement joints are easy to miss on a rental until damp shows inside.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Outdoor work around Wilsontown depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.

Other services in Wilsontown
Landlord and commercial work in Wilsontown
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.
Can I do it myself?
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.
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.
Your questions about external mastic in Wilsontown
Can you do external mastic in Wilsontown?
Yes. Our work covers the whole of Scotland, and Wilsontown is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you help a landlord with a rental near Breich station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Mould in or behind the old joints
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
To make quoting easier, let us know:
- Where the property is
- How we’d reach the joints
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
If you are in Wilsontown and need external mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
