External & façade joints in Surbiton, Greater London
Professional external mastic in and around Surbiton, with every bit of old sealant taken out first and a 12-month guarantee.
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we handle external mastic in Surbiton
For buildings in Surbiton, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on joints between brick and frames, brickwork movement joints and concrete & block, and people most often call us about failed sealant between panels on a façade and rigid filler in a joint that should flex.
Outside work in London starts with access: side passages, upper floors and where to park. In Surbiton, joints up high may need ladders or other access, which is worth talking through when you book.
All of our work is guaranteed for twelve months.

Questions from Surbiton
Is Surbiton in your area for external mastic?
Yes. We work across London and the South East, and Surbiton is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Surbiton station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start.
Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
How much does external mastic cost in Surbiton?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Whether the work is at height
- Which sealant suits the joint
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, so you know where you stand.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Any access issues, like height or stairs
- The rough size of the job
- The problem you’ve noticed
- Whether it has been sealed before
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.

External mastic in Surbiton: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hampton Court Palace (about 1.8 miles north-west) nearby, there’s older building stock in the area around Surbiton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around St Mark's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Surbiton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Surbiton, the repair is bigger than a sealant job.
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

Advice

Landlords and agents in Surbiton can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Do you need external mastic in Surbiton?
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Failed seals between different materials
- Movement joints filled with mortar instead of sealant
If you let a flat or house near Surbiton station, split movement joints are easy to miss on a rental until damp shows inside.
