External mastic for homes and businesses in Albourne Street
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Typical jobs include panel joints letting water in and cracked joints where brick meets render or frames, on render & cladding joints, copings & trims and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Albourne Street is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Keeping the joints in good condition
So the new joints stay in good condition:
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Make sure movement joints are not pointed over
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building. Somewhere as small as Albourne Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Related advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Albourne Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Domestic, commercial and hotel work

External mastic in Albourne Street: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Albourne CofE Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as The Parish Church of St Bartholomew, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Hassocks station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

When something else is needed

- Cracking across the wall rather than at a joint
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
