External mastic in Margaretting, done properly
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. We work on brickwork movement joints, concrete & block and copings & trims, and the jobs we see most are sealant pulling away from one side of the joint and rain getting behind render or cladding at a joint.
Older homes in small places like Margaretting may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Do you need external mastic in Margaretting?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
The most common problems we see are:
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
If you let a flat or house near Ingatestone station, outside joints that have cracked can let damp into a rental, so check them between lets.

Advice
FAQs for Margaretting
Will you come out to Margaretting?
Yes, Margaretting is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Margaretting in your area for external mastic?
Yes, Margaretting is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Are you fully insured?
Yes. We’re fully insured.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- 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
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Façade panels
Why act early in Margaretting
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Margaretting can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

Margaretting buildings and the weather
With historic houses such as Hylands (about 1.8 miles north-east) nearby, there’s older building stock in the area around Margaretting as well as newer homes. In older buildings, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Anglo European School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Margaret, older walls, gutters and the joints where extensions meet them need a flexible sealant.
