External Mastic in Cliffs End
Professional external mastic in and around Cliffs End, with old sealant always removed completely.
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
External mastic in Cliffs End
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on façade panels, brickwork movement joints and copings & trims, and common reasons people get in touch are hard, crazed mastic that has stopped moving and joints with sealant missing in places.
In a village or hamlet like Cliffs End, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same 12-month guarantee.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

What does external mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before any work starts.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
How the visit works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. For a village or hamlet like Cliffs End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

What external mastic looks like in Cliffs End
Cliffs End is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s 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.
Homes close to St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Thanet Parkway station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Cliffs End is about 2 miles west of Ramsgate, in Kent. Across the CT12 area, we can carry out external mastic at your property. We cover 922 towns and villages across Kent, large and small. You can also see our page for Chelmsford, roughly 47 miles from Cliffs End.

Local landmarks in Cliffs End

Why it’s worth doing now in Cliffs End
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Cliffs End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

What we’re called out for in Cliffs End
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
People usually contact us after spotting one of these:
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
Schools such as Chilton Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- What insurance they hold
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- Whether the sealant suits the joint
What affects the quote in Cliffs End
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The old material and how stubborn it is
- When we can work, for business premises
- The type of sealant required
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
What we need to know
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- If someone has resealed it before
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
