External & façade joints in Birchington, Kent
We cover Birchington for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
Why act early in Birchington
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. In an older home around Birchington, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

External mastic for homes and businesses in Birchington
On houses, flats and commercial buildings across Birchington, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Typical jobs include weathered mastic that no longer stretches and cracked joints where brick meets render or frames, across joints between brick and frames, copings & trims and concrete & block.
In a smaller place like Birchington, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
Whatever the size of the job, it’s backed by our 12-month guarantee in Birchington and across Kent.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access. For a job in Birchington, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Birchington questions
Do you cover smaller places like Birchington?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Birchington affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can you do several jobs on one visit?
Yes. Just list everything you need.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Brickwork movement joints
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Copings & trims
- Concrete & block
When to call us in Birchington
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
The problems people generally mention when they call include:
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
If you let a flat or house near Birchington-On-Sea station, outside joints that have cracked can let damp into a rental, so check them between lets.

Walls and rooflines in Birchington
Birchington is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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 Birchington Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.
