About our external mastic in Brompton
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on brickwork movement joints, façade panels and copings & trims, and the jobs we see most are moss and dirt in joints with no sealant left and water getting into walls through failed joints.
In and around Brompton, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
All our work comes with a one-year guarantee.

What else we do in Brompton
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Do not let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Copings & trims
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Parking around Brompton is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

Advice
Brompton: your questions answered
Do you work for landlords with property near Chatham station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is Brompton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How much does external mastic cost in Brompton?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
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.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
What we’re called out for in Brompton
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Panel joints letting water in
- Water getting into walls through failed joints
For an older house near a landmark such as Brompton Garrison Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Which sealant they’ll use, and why
- How the colour is chosen
- What insurance they hold
- Whether they seal over old material or remove it
Brompton buildings and the weather
Brompton is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Restoration House (about 1.1 miles west) are a reminder that the area around Brompton has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Brompton-Westbrook Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Chatham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
