External mastic in Etchingwood
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. Typical jobs include cracked joints where brick meets render or frames and joints with sealant missing in places, across brickwork movement joints, render & cladding joints and concrete & block.
External sealant needs dry, clean surfaces, so work around Etchingwood is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Your job is guaranteed for a year, as with all our work.

External mastic in Etchingwood: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Buxted station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Mary the Virgin include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Etchingwood, 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 start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Mention if the joints have been sealed before

What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Façade panels
- Joints between brick and frames
- Render & cladding joints
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep high-pressure jets off the joints
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Etchingwood questions
Do you work for landlords with property near Buxted station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Etchingwood within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Common problems we fix in Etchingwood
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Common reasons people contact us include:
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
Schools such as Uckfield College are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote

- What guarantee comes with the work
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
