How we handle external mastic in Street End
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include failed seals between different materials and joints with sealant missing in places, across brickwork movement joints, façade panels and copings & trims.
External sealant needs dry, clean surfaces, so work around Street End is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Walls and rooflines in Street End
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Canterbury East station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we cannot put right
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

What happens on the day
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In a small place like Street End, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- 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 about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Questions from Street End
Do you cover Street End for external mastic?
Yes. We work across London and the South East, and Street End is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is Street End within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
