External mastic in Bevendean, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have rain getting behind render or cladding at a joint and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
Around Bevendean, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Each job carries a 12-month guarantee.

The process
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In a smaller place like Bevendean, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Outside joints around Bevendean
Bevendean is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Holy Nativity Community Project, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Moulsecoomb station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

When to call us in Bevendean
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
People usually contact us after spotting something like this:
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
For site and facilities teams at buildings such as Bevendean Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Bevendean, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Keeping the joints in good condition
So the new joints stay in good condition:
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we’ve said otherwise
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What affects the quote in Bevendean
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
FAQs for Bevendean
Is external mastic in a coastal place like Bevendean any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Moulsecoomb station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Do you work in Bevendean?
Yes. We work in Bevendean, as part of our work across South East England, London and Scotland. To book, ring 0345 464 0079 or drop us an email.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one.
