About our external mastic in Cessnock
A movement joint is only as good as its depth. 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 cracked joints where brick meets render or frames and hard, crazed mastic that has stopped moving, we can help.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Cessnock, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.
Every job comes with our 12-month guarantee, wherever you are in Glasgow.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Cessnock
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
The most common problems we see are:
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
For landlords with property near Exhibition Centre station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before booking anyone
- Whether the sealant suits the joint
- How long the guarantee is
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.

Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Parking in city streets around Cessnock can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Walls and rooflines in Cessnock
Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it. Cessnock is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

Tenement House, about 1.4 miles north-east, is one of the historic houses in the wider area around Cessnock, and older homes nearby need a sealant that suits their walls.
