About our external mastic in Eccles
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. Typical jobs include gaps where render, brick and frames meet and failed sealant between panels on a façade, on concrete & block, copings & trims and brickwork movement joints.
Around Eccles, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Common questions in Eccles
Is Eccles in your area for external mastic?
Yes. Our work covers London and the South East, and Eccles is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near New Hythe station?

What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
Should I try DIY first?
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.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Walls and rooflines in Eccles
Historic houses like Starkey Castle (about 3.2 miles north) are a reminder that the area around Eccles has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like St Mark's Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to New Hythe station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Eccles, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The joint faces are cleaned and primed where the sealant needs 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.
Getting ready for the visit

When it isn’t the sealant
In fairness, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep water from gutters off the wall
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Older cottages and farmhouses around Eccles can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

How the job changes by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
