Why act early in Innis nan Lìon
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. 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.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Full insurance on every job
- White, clear, grey or coloured to suit, where the product allows
- One-year guarantee on every job
- We leave the area clean and tidy

How we handle external mastic in Innis nan Lìon
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We’re often asked to deal with movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint, across concrete & block, render & cladding joints and joints between brick and frames.
In and around a place like Innis nan Lìon, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

External mastic in Innis nan Lìon: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
For jobs in and around Innis nan Lìon, choosing the right material for each joint is as important as a tidy finish.

Honest limits
To be straight with you, there are a few things sealant won’t fix:

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, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
