Problem with your movement joints in Chart Sutton? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Brick movement joints where the sealant has split

When to call us in Chart Sutton
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
If you live in an older home near Church of St Michael, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Chart Sutton, done properly
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with weathered mastic that no longer stretches and weeds or debris growing in open joints, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Chart Sutton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Chart Sutton and everywhere else we cover.

Quotes for external mastic in Chart Sutton
There’s no set price list, because no two jobs are the same. The quote depends on:
- The old material and how stubborn it is
- The type of sealant required
- How many rooms, windows or areas are involved
- Any working-time requirements on site
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Chart Sutton questions
I let a flat near Bearsted station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Is Chart Sutton in your area for external mastic?
Yes, Chart Sutton is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Should I point up the gap in my brickwork?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Chart Sutton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Keep water from gutters off the wall
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere like Chart Sutton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Clear the area around the work
- Keep children and pets away from the work area
- Mention any parking rules near the property

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Copings & trims
External mastic in Chart Sutton: local notes
With historic houses such as Stoneacre (about 2 miles north) nearby, there’s older building stock in the area around Chart Sutton 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Langley Park Primary Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Bearsted station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
