External mastic in East Bergholt, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. Common call-outs are for cracked joints where brick meets render or frames and hard, crazed mastic that has stopped moving, on copings & trims, façade panels and brickwork movement joints.
Homes around East Bergholt range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why act early in East Bergholt
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a smaller place like East Bergholt, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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.

East Bergholt: your questions answered
Is external mastic in a coastal place like East Bergholt any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to East Bergholt?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Do you have insurance?
Yes. Full insurance covers our work.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

Advice
East Bergholt buildings and the weather
East Bergholt is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as East Bergholt High School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

When to call us in East Bergholt
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
For landlords with property near Manningtree station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Is VAT in the price?
- How hidden problems are handled
- When the joint can take water or movement
- How the surfaces are prepared before sealing
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Tell anyone working on the walls about the movement joints
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Never let anyone fill a movement joint with mortar
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
