External mastic in St Margaret's at Cliffe
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. If you are dealing with weeds or debris growing in open joints and rain getting behind render or cladding at a joint, we can help, on façade panels, copings & trims and render & cladding joints alike.
In and around St Margaret's at Cliffe, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

St Margaret's at Cliffe: your questions answered
Is external mastic in a coastal place like St Margaret's at Cliffe any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
I let a flat near Martin Mill station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
How long does external mastic take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. Your quote will say how long we expect yours to take.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
What is backing rod for?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only.
Are you insured?
Yes. We are fully insured.

St Margaret's at Cliffe buildings and the weather
St Margaret's at Cliffe 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Martin Mill station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of St Margaret, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as St Margaret's-at-Cliffe Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. For a job in St Margaret's at Cliffe, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Related advice
Looking after it afterwards
After the cure time, these simple habits help:
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In a smaller place like St Margaret's at Cliffe, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

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 matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
