External Mastic in Winchelsea Beach
External mastic across Winchelsea Beach and nearby, with old sealant always removed completely and a one-year guarantee.
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
About our external mastic in Winchelsea Beach
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on concrete & block, brickwork movement joints and copings & trims, and the jobs we see most are sealant pulling away from one side of the joint and brick movement joints where the sealant has split.
Older homes in small places like Winchelsea Beach may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All of our work is guaranteed for twelve months.

External mastic in Winchelsea Beach: local notes
Winchelsea Beach is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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 St Thomas' Church of England Aided Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Winchelsea station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In a small place like Winchelsea Beach, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask before painting over external sealant
- Point out the joints to other trades
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Common questions in Winchelsea Beach
Is external mastic in a coastal place like Winchelsea Beach any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Winchelsea Beach?
Yes, Winchelsea Beach is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
How long does external mastic take?
As a guide, most jobs take 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.
How do I get a quote for external mastic in Winchelsea Beach?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Common problems we fix in Winchelsea Beach
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Failed seals between different materials
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
If you live in an older home near St Richard, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- Whether you can choose the colour
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
