External & façade joints in Three Oaks, East Sussex
Movement joints in Three Oaks need attention? We cut out the old, prepare the joints and apply the right sealant.

Three Oaks buildings and the weather
Three Oaks is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Durhamford Manor (about 4.9 miles north-west) nearby, there’s older building stock in the area around Three Oaks 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.
If you let a flat or house near Three Oaks station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Buckswood School, larger buildings have long runs of movement joint that eventually need resealing.
Three Oaks is about 3 miles north-east of Hastings, in East Sussex.

About our external mastic in Three Oaks
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Typical jobs include movement joints filled with mortar instead of sealant and leaking joints around cladding and façade panels, across copings & trims, joints between brick and frames and façade panels.
In a village or hamlet like Three Oaks, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, large or small.

How we quote for external mastic
We don’t publish a price list. The quote depends on:
- Which sealant suits the joint
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
To make quoting easier, please include:
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- How we’d reach the joints
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look over the joints every year, ideally after winter
- Deal with leaking gutters that soak the joints below
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Around Three Oaks, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- White, clear, grey or another colour, product permitting
- Full insurance on every job
- Old sealant always removed completely
- Every job guaranteed for a year

Common questions in Three Oaks
Does living near the coast affect external mastic in Three Oaks?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Three Oaks?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Damp that is not coming from the joint
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
Surfaces we seal
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
When to call us in Three Oaks
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
In the older streets around St Laurence's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- How the joint is cleaned and prepared
- The length of the guarantee
- Is VAT in the price?
- What happens if the job turns out different
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. In a small place like Three Oaks, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
