External mastic in Peaslake, done properly
On houses, flats and commercial buildings across Peaslake, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on copings & trims, façade panels and brickwork movement joints, and common reasons people get in touch are movement joints with cracked, split or missing sealant and movement joints filled with mortar instead of sealant.
External sealant needs dry, clean surfaces, so work around Peaslake is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Damp that isn’t coming from the joint
- Movement that is more than a sealant joint can take
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

- Joints between brick and frames
- Façade panels
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Peaslake, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

External mastic in Peaslake: local notes
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. Historic houses like Chilworth Manor (about 4.2 miles north-west) are a reminder that the area around Peaslake has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Church of St Mark, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Gomshall station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Peaslake is about 6 miles south-west of Dorking, in Surrey. From the centre of Peaslake to the outskirts, external mastic is available for homes and businesses alike, from flats and houses to offices and hotels.

Your questions about external mastic in Peaslake
I let a flat near Gomshall station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Peaslake?
Yes, we do. 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.
Are you fully insured?
Yes. We’re fully insured.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
How long will you be here?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we have said otherwise
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.

What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Around Peaslake, older homes often have timber in their 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 how easy the joints are to reach. You’ll have a clear quote before any work starts.
