Why act early in Gargunnock
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. In an older home around Gargunnock, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.

External mastic in Gargunnock, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you’re dealing with movement joints filled with mortar instead of sealant and water getting into walls through failed joints, we can help, whatever the surface.
In and around a place like Gargunnock, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Honest limits
A few problems are outside what sealant work can do:
- Adding movement joints to masonry that has none
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer

Common problems we fix in Gargunnock
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
These are the problems we are asked about most:
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
Around Gargunnock, as everywhere, external mastic is only as good as the preparation behind it.

How it works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Around Gargunnock, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Tell us about any water getting in

Looking after it afterwards
So the new joints stay in good condition:
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we’ve said otherwise
- Show decorators and builders where the movement joints are
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
External mastic in Gargunnock: local notes
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Homes close to Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What guarantee comes with external mastic in Gargunnock?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Should I point up the gap in my brickwork?
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.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the 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.
