External mastic in St Michaels, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have sealant that has lost its bond to the brick or render and failed seals between different materials, we can put it right, whatever the surface.
Older homes in small places like St Michaels may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What we cannot put right
It helps to know what we can’t do:
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none

Where we work in St Michaels
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
- Copings & trims
Keeping the joints in good condition
So the new joints stay in good condition:
- Leave the joints unpainted unless we have said otherwise
- Don’t let climbing plants root in the sealant
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Landlords, agents and businesses in St Michaels
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Where a wall is exposed, as many are in small places like St Michaels, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Why us?
- Experience in homes, commercial sites and hotels
- Anti-fungal silicone where joints get wet

- We never seal over old sealant

Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Outside joints around St Michaels
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. Historic houses like Smallhythe Place (about 3.3 miles south) are a reminder that the area around St Michaels 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.
For site and facilities teams at buildings such as St Michael's Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Michael include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Your questions about external mastic in St Michaels
Do you cover smaller places like St Michaels?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover St Michaels for external mastic?
Yes, St Michaels is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch. If it has already been filled, we can usually cut it out and reseal it.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as St Michaels, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
