External mastic in Mosstodloch, done properly
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. We work on joints between brick and frames, façade panels and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and sealant pulling away from one side of the joint.
Outside joints can only be sealed when they’re dry, so work in Mosstodloch depends on the weather. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months, in Mosstodloch and everywhere else we cover.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
External mastic in Mosstodloch: local notes
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Milne's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When it is not the sealant
New sealant can’t fix everything, and we’ll tell you before work begins. It will not solve:
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

How we quote for external mastic
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- Any working-time requirements on site
- The number and length of the joints
- Whether old sealant or filler has to be cut out
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
- The problem you’ve noticed
- Access, such as stairs, a lift or height
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.
Why it’s worth doing now in Mosstodloch
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. 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.
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Wash walls gently around the sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Questions from Mosstodloch
Is there a guarantee on external mastic in Mosstodloch?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Mosstodloch for external mastic?
Yes, Mosstodloch is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will tell you how long to expect.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Around Mosstodloch, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Advice
Do you need external mastic in Mosstodloch?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
These are the problems we’re asked about most:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Speymouth Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- What insurance they hold
- How the joint is cleaned and prepared
