External & façade joints in Kingham, Oxfordshire
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Kingham. ARBOMaster approved applicators, fully insured, with a one-year guarantee.

- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
External mastic in Kingham
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. If you have cracked joints where brick meets render or frames and plants rooting in failed movement joints, we can help, on render & cladding joints, brickwork movement joints and joints between brick and frames alike.
Around Kingham, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Your questions about external mastic in Kingham
I let a flat near Kingham station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Kingham?
Yes, Kingham is covered. 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.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Can I add another job to the visit?
Yes. Just list everything you need.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Kingham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Concrete & block
- Façade panels
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Kingham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.

When to call us in Kingham
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
Homes close to Church of St Andrew include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- Who does the work, and how experienced they are
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Which sealant they’ll use, and why
How to look after the new joints
So the new joints stay in good condition:
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off 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.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Walls and rooflines in Kingham
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. With historic houses such as Chastleton House (about 3.3 miles north) nearby, there’s older building stock in the area around Kingham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Kingham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Kingham Primary School, larger buildings have long runs of movement joint that eventually need resealing.
