How we handle external mastic in Bexhill-on-Sea
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, render & cladding joints and façade panels, and the jobs we see most are weeds or debris growing in open joints and failed seals between different materials.
Around Bexhill-on-Sea, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

When to call us in Bexhill-on-Sea
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The problems people generally mention when they call are:
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
Managing a site like King Offa Primary Academy? Then its movement joints, gutters and trims need looking after like any other building’s.

Your questions about external mastic in Bexhill-on-Sea
Is Bexhill-on-Sea in your area for external mastic?
Yes, Bexhill-on-Sea is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Does the coastal weather in Bexhill-on-Sea affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we will confirm the access.

Walls and rooflines in Bexhill-on-Sea
Bexhill-on-Sea is close to 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. Compared with the north and west, the South East gets less rain, 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 Bexhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a job in Bexhill-on-Sea, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Advice
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Black mould and gaps in sealant do not fix themselves, and in a busy household in Bexhill-on-Sea they spread with every shower and every downpour. Now is the easy time to put it right.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

What we can’t put right
It helps to know what we cannot do too:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
- Walk round the building once a year and look at the joints
- Make sure movement joints aren’t pointed over
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
