Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Point out the joints to other trades
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. 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 it’s worth resealing at the first signs.
External mastic in Shorne, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on render & cladding joints, façade panels and joints between brick and frames, and common reasons people get in touch are panel joints letting water in and old sealant gone brittle and cracked.
In a village or hamlet like Shorne, 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.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Render that is blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

What affects the quote in Shorne
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- The problem you’ve noticed
- Where the property is
- Whether it has been sealed before
- Access, such as stairs, a lift or height

FAQs for Shorne
Does the coastal weather in Shorne affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Shorne?
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.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes anything from a few hours to several days, depending on the building. Somewhere like Shorne 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Why act early in Shorne
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. In a small place like Shorne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why us?
- A 12-month guarantee on all work
- Colour agreed with you before we start
- Old sealant always removed completely
- Colour picked to suit the job

Outside joints around Shorne
Shorne is close to 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Higham station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Shorne Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
