Questions from Minnigaff
Is there a guarantee on external mastic in Minnigaff?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you do external mastic in Minnigaff?
Yes. Our work covers the whole of Scotland, and Minnigaff is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
External mastic in Minnigaff
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include joints where the bead has come unstuck and joints pointed up with cement by mistake, across render & cladding joints, brickwork movement joints and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Minnigaff is planned around the weather. Let us know about access to every wall and roofline.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
How we quote for external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- The number and length of the joints
Combining jobs into one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Landlord and commercial work in Minnigaff
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
For anyone letting property in or around Minnigaff, several properties can be quoted together. Just tell us the addresses and what each one needs.
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Minnigaff, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why us?
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely
- A 12-month guarantee on all work
- Over 20 years’ experience

Advice
Minnigaff buildings and the weather
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.
If you look after a building such as Douglas Ewart High School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Monigaff Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
