Signs you need external mastic in Cold Norton
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
People generally contact us after spotting one of these:
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
Rented homes near North Fambridge station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Before booking anyone
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
- Whether you can choose the colour
- How long to leave it before use
About our external mastic in Cold Norton
On houses, flats and commercial buildings across Cold Norton, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have weathered mastic that no longer stretches and movement joints filled with mortar instead of sealant, we can help.
Somewhere as small as Cold Norton, homes and farm buildings often face open ground, 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 of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Cold Norton
How the job changes by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before we start. Sealant will not put right:
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Where we work in Cold Norton
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames

How it works
We keep the work tidy and contained to the area we’re working on. Expect the work to take anything from a few hours to several days, depending on the building. Somewhere as small as Cold Norton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

Related advice
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
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.
Walls and rooflines in Cold Norton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Cold Norton Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around St Stephen's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Your questions about external mastic in Cold Norton
Is Cold Norton within the area you cover?
Yes, Cold Norton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near North Fambridge station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
