External mastic in South Moreton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We’re often asked to deal with cracked joints where brick meets render or frames and moss and dirt in joints with no sealant left, on façade panels, concrete & block and joints between brick and frames.
In a village or hamlet like South Moreton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, in South Moreton and everywhere else we cover.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Signs you need external mastic in South Moreton
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
Schools such as South Moreton Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like South Moreton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Mention any tricky access

South Moreton questions
Will you come out to South Moreton?
Yes, South Moreton is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is South Moreton in your area for external mastic?
Yes, South Moreton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. We will reseal it with a flexible sealant.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking.
What does external mastic cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us with a short description of the job.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Quotes for external mastic in South Moreton
The quote reflects the job in front of us. We look at:
- How much there is to do
- The number of rooms or windows
- Whether there’s mould to deal with
- When we can work, for business premises
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- Where the property is
- How we’d reach the joints
- Photos by email, if that is easy
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details, and pictures are welcome.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
- Leave the joints unpainted unless we have said otherwise
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.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- Concrete & block
- Copings & trims

- Render & cladding joints

South Moreton buildings and the weather
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 Brightwell Manor (about 1.9 miles north-east) nearby, there’s older building stock in the area around South Moreton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Cholsey station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
