How the visit works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the building. For a place like Dinnet, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

How we handle external mastic in Dinnet
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you have failed sealant between panels on a façade and gaps where render, brick and frames meet, we can help.
Outside joints can only be sealed when they’re dry, so work in Dinnet depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
You get a one-year guarantee, the same in Dinnet as everywhere else we work.

Questions from Dinnet
Is there a guarantee on external mastic in Dinnet?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Dinnet?
Yes, Dinnet 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 you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long does external mastic take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. Your quote will say how long we expect yours to take.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
How to look after the new joints
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Leave the joints unpainted unless we have said otherwise
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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

External mastic in Dinnet: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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.
Around Dinnet, as everywhere, external mastic is only as good as the preparation behind it. If you live in an older home near Dinnet Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
