External mastic in Ravenstruther: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Lanark Grammar School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Carstairs station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Ravenstruther
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Typical jobs include joints pointed up with cement by mistake and sealant pulling away from one side of the joint, across copings & trims, joints between brick and frames and render & cladding joints.
External sealant needs dry surfaces, so outdoor work around Ravenstruther is planned around the weather. Tell us how to reach each wall, gutter and roofline.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
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.
DIY versus a professional finish
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Landlords, agents and businesses in Ravenstruther
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

How to look after the new joints
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we’ve said otherwise
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
When something else is needed
New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Ravenstruther: your questions answered
I let a flat near Carstairs station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Is Ravenstruther within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
What does external mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. 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.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
