External & façade joints in Lumphanan, Aberdeenshire
External mastic for Lumphanan and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
Why it’s worth doing now in Lumphanan
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

External mastic in Lumphanan
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, joints between brick and frames and concrete & block, and the jobs we see most are plants rooting in failed movement joints and leaking joints around cladding and façade panels.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All our work comes with a one-year guarantee, wherever you are in Aberdeenshire.

External mastic in Lumphanan: local notes
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Stothart Memorial Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Lumphanan
Will you come out to Lumphanan?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on external mastic in Lumphanan?
All our work, in Lumphanan and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Do you have insurance?
Yes. We’re fully insured.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Common problems we fix in Lumphanan
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. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
In and around Lumphanan, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Outdoor work around Lumphanan 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.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- 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.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Clear the area around the work

What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
