External & façade joints in Sevington, Kent
Problem with your movement joints in Sevington? We cut out the old, prepare the joints and apply the right sealant.
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
External mastic in Sevington, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on façade panels, copings & trims and brickwork movement joints, and people most often call us about movement joints filled with mortar instead of sealant and water getting into walls through failed joints.
Somewhere as small as Sevington, homes and farm buildings often face open ground, 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.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep soil, plants and ivy away from the joints
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Sevington questions
Do you cover smaller places like Sevington?
Yes. Sevington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Sevington?
Yes, Sevington is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
External mastic in Sevington: local notes
With historic houses such as Godinton House (about 3.9 miles north-west) nearby, there’s older building stock in the area around Sevington 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Willesborough Junior School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Ashford International station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Signs you need external mastic in Sevington
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Façade panels
