External mastic for homes and businesses in Newbury's
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 so the line blends in. If you have cracked joints where brick meets render or frames and brick movement joints where the sealant has split, we can put it right, whatever the surface.
In a village or hamlet like Newbury's, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All our work comes with our one-year guarantee, wherever you are in East Sussex.

Leave it or put it right?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Older cottages and farmhouses around Newbury's can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
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.

Outside joints around Newbury's
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. Historic houses like Wadhurst Castle (about 1.5 miles south-west) are a reminder that the area around Newbury's has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Rehoboth Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Wadhurst station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before sealing.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
What we’re called out for in Newbury's
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Most people get in touch after spotting something like this:
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Sealant pulling away from one side of the joint
For site and facilities teams at buildings such as Uplands Community College, larger buildings have long runs of movement joint that eventually need resealing.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. For a village or hamlet like Newbury's, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- 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.

- Mention any sign-in or site rules at work premises

Is the work guaranteed?

Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you do commercial work?

Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start from the range available.
