External & façade joints in South Leigh, Oxfordshire
Movement joints in South Leigh need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

External mastic for homes and businesses in South Leigh
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you are dealing with failed sealant between panels on a façade and joints where the bead has come unstuck, we can help.
Outside joints can only be sealed when they’re dry, so work in South Leigh is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

External mastic in South Leigh: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Minster Lovell Hall (about 4.6 miles west) nearby, there’s older building stock in the area around South Leigh as well as newer homes. Where a home is older, 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 James, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Wood Green School, larger buildings have long runs of movement joint that eventually need resealing.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Common questions in South Leigh
Can you do external mastic in South Leigh?
Yes. We work across London and the South East, and South Leigh is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Hanborough station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you insured?
Yes. Mr Mastic is fully insured.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
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 access only has to be arranged once. Around South Leigh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What we’re called out for in South Leigh
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Look out for any of the following:
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
If you let a flat or house near Hanborough station, split movement joints are easy to miss on a rental until damp shows inside.
Before booking anyone
- Whether the sealant suits the joint
- What insurance they hold
- When the joint can take water or movement
- Whether all the old sealant comes out first
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like South Leigh, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
