External mastic for homes and businesses in Davidston
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 take the old material out and do it properly. We work on joints between brick and frames, façade panels and concrete & block, and people most often call us about rain getting behind render or cladding at a joint and old sealant gone brittle and cracked.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What else we do in Davidston
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Façade panels
How to look after the new joints
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Check external joints each spring
- Tell anyone working on the walls about the movement joints
- Act on the first splits you see
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Questions from Davidston
Do you work for landlords with property near Invergordon station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Davidston?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building. We will confirm how long when we quote.
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

External mastic in Davidston: local notes
Davidston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Davidston, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Signs you need external mastic in Davidston
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
Letting a property close to Invergordon station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
