External Mastic in Lower Dicker
Movement joints in Lower Dicker need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Lower Dicker, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

About our external mastic in Lower Dicker
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on brickwork movement joints, concrete & block and render & cladding joints, and people most often call us about failed sealant between panels on a façade and gaps where render, brick and frames meet.
In a village or hamlet like Lower Dicker, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

What affects the quote in Lower Dicker

- Whether old sealant or filler has to be cut out
- Access and height
- When we can work, for business premises
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- Whether it has been sealed before
- A few pictures by email, if you can
- Roughly how big the job is
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Lower Dicker, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

Your questions about external mastic in Lower Dicker
Do you cover smaller places like Lower Dicker?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Lower Dicker in your area for external mastic?
Yes, Lower Dicker is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
How long will you be here?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including the preparation. We will confirm how long when we quote.

Outside joints around Lower Dicker
With historic houses such as Horselunges Manor (about 1.2 miles east) nearby, there’s older building stock in the area around Lower Dicker as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Berwick (Sussex) station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Zoar Strict Baptist Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Hellingly Community Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Aftercare tips
A little care helps the new joints last. We recommend:
- Keep high-pressure jets off the joints
- Make sure movement joints are not pointed over
- Check external joints each spring
- Tell anyone working on the walls about the movement joints
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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 doesn’t work out, we can still put it right.
