External mastic in Camber
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on façade panels, render & cladding joints and concrete & block, and common reasons people get in touch are sealant that has lost its bond to the brick or render and brick movement joints where the sealant has split.
Somewhere as small as Camber, homes and farm buildings often face open ground, 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.
Whatever the size of the job, it’s backed by our one-year guarantee in Camber and across East Sussex.

What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Camber needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Advice
What external mastic looks like in Camber
Camber 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Rye station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. In a small place like Camber, homes can be exposed to wind and rain, which finds any gap, 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. Call for a quick quote.

Different surfaces, different methods
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
What we’re called out for in Camber
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Common reasons people contact us are:
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
For an older house near a landmark such as St Thomas the Apostle, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Which colour the sealant will be
- How hidden problems are handled
- The length of the guarantee
- Whether they’re fully insured
Aftercare tips
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Keep soil, plants and ivy away from the joints
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we’ve said otherwise
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Questions from Camber
Is external mastic in a coastal place like Camber any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Camber?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

What else we do in Camber
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
