Sealing brickwork movement joints, render, cladding and façade joints for Cambusnethan, backed by a 12-month guarantee. Call for a quick quote.
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Panel joints letting water in
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Outdoor work around Cambusnethan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

External mastic in Cambusnethan
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on brickwork movement joints, copings & trims and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and movement joints filled with mortar instead of sealant.
Outside joints can only be sealed when they’re dry, so work in Cambusnethan depends on the weather. Tell us how to reach each wall, gutter and roofline.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

External mastic in Cambusnethan: local notes
Historic houses like Cambusnethan House (about 2.5 miles south-west) are a reminder that the area around Cambusnethan has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Wishaw station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Coltness High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you need external mastic in Cambusnethan?
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 and make things worse.
Signs it’s time to call us include:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
Homes close to North Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before booking anyone
- Is the old sealant removed completely?
- What preparation is included
- What guarantee comes with the work
- How the colour is chosen
What happens if it’s left?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Cambusnethan, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
