Why it’s worth doing now in Rotherbridge
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Rotherbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

How we handle external mastic in Rotherbridge
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on render & cladding joints, brickwork movement joints and concrete & block, and people most often call us about joints with sealant missing in places and leaking joints around cladding and façade panels.
External sealant needs dry, clean surfaces, so work around Rotherbridge is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, large or small.

How the job changes by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.
Outside joints around Rotherbridge
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. With historic houses such as Petworth House (about 1.2 miles north-east) nearby, there’s older building stock in the area around Rotherbridge 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.
Homes close to The Parish Church of All Hallows include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Pulborough station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Petworth Cof E Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
The work is kept neat and contained to the joints we are treating. The job usually takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. In a small place like Rotherbridge, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Fix overflowing gutters above sealed joints
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
Don’t let soil, plants or ivy build up against the new joints. 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.

Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Rotherbridge questions
I let a flat near Pulborough station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is Rotherbridge within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
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.
Quotes for external mastic in Rotherbridge
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- How easy the joints are to reach
- How much there is to do
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
When something else is needed
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
