Walls and rooflines in Inchmagrannachan
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 sound outside sealant is part of that.
Letting a property close to Dunkeld & Birnam station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Inchmagrannachan
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on copings & trims, façade panels and brickwork movement joints, and the jobs we see most are plants rooting in failed movement joints and brick movement joints where the sealant has split.
External sealant needs dry surfaces, so outdoor work around Inchmagrannachan is planned around the weather. Tell us how to reach each wall, gutter and roofline.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

Advice
Common problems we fix in Inchmagrannachan
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for these signs:
- Cracked joints where brick meets render or frames
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
In and around Inchmagrannachan, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Whether you can choose the colour
- Whether they seal over old material or remove it
- What the cure time is
- Is VAT in the price?
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Around Inchmagrannachan, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll send you a clear quote for the lot.

How we quote for external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The old material and how stubborn it is
- When we can work, for business premises
- How many areas need sealing
- The size of the job
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Before you ask for a quote, have a think about:
- A few photos by email, if you can
- How we’d reach the joints
- What’s wrong with the joints now

Questions from Inchmagrannachan
Do you cover smaller places like Inchmagrannachan?
Yes, Inchmagrannachan is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Dunkeld & Birnam station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
Should I try DIY first?
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.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What the job involves on each surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
