- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
What happens on the day
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. Somewhere as small as Cuddesdon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

External mastic in Cuddesdon
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on render & cladding joints, concrete & block and copings & trims, and common reasons people get in touch are rigid filler in a joint that should flex and moss and dirt in joints with no sealant left.
Somewhere as small as Cuddesdon, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All our work is covered by a one-year guarantee.

Your questions about external mastic in Cuddesdon
Is Cuddesdon in your area for external mastic?
Yes, Cuddesdon is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Is there a guarantee on external mastic in Cuddesdon?
All our work, in Cuddesdon and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
Are you insured?
Yes. Full insurance covers our work.
Signs you need external mastic in Cuddesdon
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
These are the problems we’re asked about most:
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
For an older house near a landmark such as Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- Who turns up on the day
- How long the guarantee is
- What product goes in the joint
- Is the old sealant removed completely?
What we can’t put right
In fairness, there are a few things sealant won’t fix:
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Façade panels
- Concrete & block
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Cuddesdon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Cuddesdon buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Garsington Manor (about 1.3 miles south-west) are a reminder that the area around Cuddesdon 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.
Managing a site like Garsington Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
