Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Croftfoot, damp can travel a long way before it shows.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

External mastic in Croftfoot, done properly
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. Typical jobs include failed seals between different materials and hard, crazed mastic that has stopped moving, across joints between brick and frames, brickwork movement joints and concrete & block.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. In Croftfoot, those joints dry out over time and let water in behind the render or cladding.
Big or small, you get the same one-year guarantee.

Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Why is there a gap in my brick wall?
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.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What the job involves on each surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
What external mastic looks like in Croftfoot
Croftfoot 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.

Common problems we fix in Croftfoot
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
Schools such as St Margaret Mary's Secondary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Which colour the sealant will be
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- When the joint can take water or movement
