We cover Greatstone-on-Sea for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

External mastic in Greatstone-on-Sea, done properly
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. If you’re dealing with water getting into walls through failed joints and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Around Greatstone-on-Sea, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Leave the joints unpainted unless we have said otherwise
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Common problems we fix in Greatstone-on-Sea
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Brick movement joints where the sealant has split
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
For site and facilities teams at buildings such as Greatstone Primary School, its movement joints, gutters and trims need looking after like any other building’s.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Greatstone-on-Sea, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before

Related advice
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Older cottages and farmhouses around Greatstone-on-Sea can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. We can quote a run of properties together.
Common questions in Greatstone-on-Sea
Does the coastal weather in Greatstone-on-Sea affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Greatstone-on-Sea?
Yes, Greatstone-on-Sea is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What is backing rod for?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Greatstone-on-Sea buildings and the weather
Greatstone-on-Sea 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Peter's, an extension built onto an older house moves differently, and the joint between them takes the strain.
