South Stifford buildings and the weather
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.
If you look after a building such as Harris Primary Academy Chafford Hundred, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Chafford Hundred station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

About our external mastic in South Stifford
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Typical jobs include rigid filler in a joint that should flex and failed seals between different materials, across copings & trims, brickwork movement joints and façade panels.
Outbuildings, garages and conservatories around homes in places like South Stifford add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
You get a one-year guarantee, the same in South Stifford as everywhere else we work.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Your questions about external mastic in South Stifford
Can you do external mastic in South Stifford?
Yes, South Stifford is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Is South Stifford within the area you cover?
Yes. South Stifford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Wash walls gently around the sealant
- Act on the first splits you see
- Make sure movement joints are not pointed over
- Do not let climbing plants root in the sealant
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
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.
Common problems we fix in South Stifford
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Panel joints letting water in
Homes close to All Saints' Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. A visit to South Stifford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about any water getting in
- Mention any tricky access
- Keep children and pets away from the work area

How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
What we cannot put right
We won’t take on work that will not last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
