- Hard, crazed mastic that has stopped moving

- Sealant that has lost its bond to the brick or render
How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job generally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. In Faversham, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- 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.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

External mastic in Faversham
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Common call-outs are for damp patches traced to an open external joint and old sealant gone brittle and cracked, on brickwork movement joints, copings & trims and concrete & block.
Garage door frames, porches and roofline trims are all part of external work in a town like Faversham. Where two materials meet, they move differently, and the sealant has to allow for it.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
- Act on the first splits you see
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Outside joints around Faversham
Faversham is within about 3 miles of 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. 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.
In the older streets around Church of St Mary Magdalene, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Faversham station, outside joints that have cracked can let damp into a rental, so check them between lets.

What else we do in Faversham
How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
Why it’s worth doing now in Faversham
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Faversham, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.

Common questions in Faversham
Can you do external mastic in Faversham?
Yes. We work across London and the South East, and Faversham is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Does living near the coast affect external mastic in Faversham?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins, matched as closely as the range allows.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Common problems we fix in Faversham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch after spotting one of these:
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
If you look after a building such as Ethelbert Road Primary School, 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
- How the surfaces are prepared before sealing
- How the colour is chosen
- Whether they’re fully insured
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
