About our external mastic in Puckaster
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on façade panels, copings & trims and joints between brick and frames, and people most often call us about weathered mastic that no longer stretches and joints with sealant missing in places.
In a village or hamlet like Puckaster, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months.

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Puckaster questions
Does the coastal weather in Puckaster affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover Puckaster for external mastic?
Yes, Puckaster is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Are you insured?
Yes, we’re fully insured.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents and landlords in Puckaster can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Common problems we fix in Puckaster
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Look out for these signs:
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
- Weathered mastic that no longer stretches
If you look after a building such as Niton Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- How the joint is cleaned and prepared
- How the colour is chosen
- What the cure time is
- The length of the guarantee
How the job changes by surface
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.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Puckaster, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What external mastic looks like in Puckaster
Puckaster is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St. John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
