What external mastic looks like in Rushenden
Rushenden is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Queenborough station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Parish Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Queenborough School and Nursery? Then its movement joints, gutters and trims need looking after like any other building’s.

External mastic for homes and businesses in Rushenden
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on copings & trims, façade panels and brickwork movement joints, and the jobs we see most are plants rooting in failed movement joints and movement joints with cracked, split or missing sealant.
In a village or hamlet like Rushenden, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. 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 isn’t right with it, ring 0345 464 0079 or send us an email.

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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Common questions in Rushenden
Does living near the coast affect external mastic in Rushenden?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you work for landlords with property near Queenborough station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Honest limits
It helps to know what we cannot do:
- Damp that isn’t coming from the joint
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Rushenden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Rushenden, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

Advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
