External mastic for homes and businesses in Surbiton Park
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have panel joints letting water in and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Surbiton Park, joints up high may need ladders or other access, which is worth talking through when you book.
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.

Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
How the visit works
The work is kept neat and contained to the area we are working on. Expect the work to take anything from a few hours to several days, depending on the building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Advice
Your questions about external mastic in Surbiton Park
I let a flat near Surbiton station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is parking an issue for external mastic in Surbiton Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Does someone need to be in?
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.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

How to look after the new joints
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
When something else is needed
It helps to know what we cannot do:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Façade panels
- Copings & trims
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Surbiton Park buildings and the weather
Historic houses like Hampton Court Palace (about 1.4 miles west) are a reminder that the area around Surbiton Park 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. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
If you look after a building such as St Andrew's and St Mark's CofE Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around St John's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Signs you need external mastic in Surbiton Park
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for any of the following:
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
Surbiton Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
