Charing External Mastic
Movement joints in Charing need attention? We remove the old material, prepare the joints and seal them properly.
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Parking around Charing is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Advice
External mastic for homes and businesses in Charing
On houses, flats and commercial buildings across Charing, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you are dealing with sealant that has lost its bond to the brick or render and rigid filler in a joint that should flex, we can help, on joints between brick and frames, concrete & block and façade panels alike.
Around Charing, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What external mastic looks like in Charing
With historic houses such as Godinton House (about 3.9 miles south-east) nearby, there’s older building stock in the area around Charing as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Peter and St Paul include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Charing Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

FAQs for Charing
I let a flat near Charing station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Charing for external mastic?
Yes, Charing is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
Will the new joint stand out?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What we are called out for in Charing
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
Rented homes near Charing station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
