About our external mastic in Holytown
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Common call-outs are for joints where the bead has come unstuck and moss and dirt in joints with no sealant left, on render & cladding joints, joints between brick and frames and copings & trims.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

DIY versus a professional finish
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What external mastic looks like in Holytown
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.
Schools such as Brannock High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Holytown station, split movement joints are easy to miss on a rental until damp shows inside. Historic houses such as Cambusnethan House, about 4.5 miles south, show how far back building around Holytown goes, and older homes nearby need a sealant that suits their walls.

FAQs for Holytown
Do you work for landlords with property near Holytown station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Holytown?
Yes, Holytown is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Around Holytown, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive

Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way and it means sorting access once. In a place like Holytown, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep soil, plants and ivy away from the joints
- Avoid pressure-washing directly into sealant joints
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
