How we handle external mastic in Trumpethill
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Typical jobs include gaps where render, brick and frames meet and rain getting behind render or cladding at a joint, across render & cladding joints, copings & trims and brickwork movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
Big or small, it’s backed by our 12-month guarantee.

Landlords, agents and businesses in Trumpethill
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

External mastic in Trumpethill: local notes
Trumpethill is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Ardgowan House, about 2.4 miles south, is one of the historic houses in the wider area around Trumpethill, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as Gourock High School, its movement joints, gutters and trims need looking after like any other building’s.

Common problems we fix in Trumpethill
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
For landlords with property near Gourock station, split movement joints are easy to miss on a rental until damp shows inside.

Questions from Trumpethill
Do you cover smaller places like Trumpethill?
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.
Do you work for landlords with property near Gourock station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
What does external mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
When something else is needed
In fairness, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Copings & trims
- Façade panels
- Brickwork movement joints
How the job changes by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a place like Trumpethill, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
