Your questions about external mastic in Ewshot
Is Ewshot within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
External mastic in Ewshot
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. If you have rigid filler in a joint that should flex and old sealant gone brittle and cracked, we can help, on concrete & block, joints between brick and frames and façade panels alike.
Older homes in small places like Ewshot may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Our work is backed for twelve months, in Ewshot and everywhere else we cover.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep soil, plants and ivy away from the joints
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Leave the joints unpainted unless we’ve said otherwise
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

Outside joints around Ewshot
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Farnham Castle (about 1.9 miles south-east) are a reminder that the area around Ewshot has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as St Mary's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as St Nicholas' School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What else we do in Ewshot
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
What we seal
- Copings & trims
- Façade panels
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere like Ewshot needs a little journey planning: 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 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on
- Mention any tricky access

Advice
Common problems we fix in Ewshot
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
These are the problems we’re asked about most:
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
Rented homes near Farnham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
