External mastic in Greenfoot, done properly
On houses, flats and commercial buildings across Greenfoot, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on copings & trims, render & cladding joints and façade panels, and common reasons people get in touch are damp patches traced to an open external joint and plants rooting in failed movement joints.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
All our work comes with our one-year guarantee, wherever you are in North Lanarkshire.

External mastic in Greenfoot: 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. 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 Buchanan High School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church Of Scotland, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What else we do in Greenfoot
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Outside jobs in Greenfoot need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Aftercare tips
So the new joints stay in good condition:
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why act early in Greenfoot
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. In a place like Greenfoot, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Signs you need external mastic in Greenfoot
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.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
Letting a property close to Gartcosh station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
