External mastic in Monkton
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. We are often asked to deal with movement joints filled with mortar instead of sealant and joints where the bead has come unstuck, on façade panels, copings & trims and concrete & block.
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 South Ayrshire.

Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. In a place like Monkton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Outside joints around Monkton
Monkton is within about 2 miles of 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. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Homes close to St Cuthbert’s Church (Monkton) include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Prestwick International Airport station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Monkton: your questions answered
Does the coastal weather in Monkton affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Prestwick International Airport station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How much does external mastic cost in Monkton?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk and let us know what needs doing and where.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Common problems we fix in Monkton
Every building moves. 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:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
If you look after a building such as Prestwick Academy, larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- When the joint can take water or movement
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Who does the work, and how experienced they are
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on

- Façade panels
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
What we do, step by step
We keep the work tidy and contained to the joints we are treating. The job generally takes a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Outdoor work around Monkton 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.
- We fit closed-cell backing rod to control 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
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
