External mastic in Newbridge: local notes
Historic houses like Landford Manor (about 3.8 miles north-west) are a reminder that the area around Newbridge has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Ashurst New Forest station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Newbridge, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you have leaking joints around cladding and façade panels and joints where the bead has come unstuck, we can help.
In a village or hamlet like Newbridge, 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.
Our work is backed for twelve months.

What affects the quote in Newbridge
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- The number of rooms or windows
- The old material and how stubborn it is
- Access and height
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work

Why act early in Newbridge
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Older cottages and farmhouses around Newbridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Your questions about external mastic in Newbridge
Can you do external mastic in Newbridge?
Yes, Newbridge is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Is Newbridge within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
Looking after it afterwards
So the new joints stay in good condition:
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere like Newbridge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Keep pets and children clear of the area while we work

Common problems we fix in Newbridge
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The most common problems we see are:
- Failed seals between different materials
- Joints pointed up with cement by mistake
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
If you look after a building such as Copythorne CofE Infant School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- Which sealant they’ll use, and why
- Whether they’re fully insured
- How long to leave it before use
- Which colour the sealant will be
Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
