External mastic in Upper Wield
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We work on façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint.
Outside joints can only be sealed when they’re dry, so work in Upper Wield is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Upper Wield and everywhere else we cover.

Work for landlords, hotels and businesses
Landlords and agents in Upper Wield can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Upper Wield needs a little journey planning: let us know about lanes, gates and parking. 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.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
- Façade panels
- Concrete & block
How to look after the new joints
A little care helps the new joints last. Our advice:
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Upper Wield questions
Do you cover smaller places like Upper Wield?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Upper Wield for external mastic?
Yes, Upper Wield is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

What else we do in Upper Wield
Walls and rooflines in Upper Wield
With historic houses such as Hall Place (about 2.2 miles east) nearby, there’s older building stock in the area around Upper Wield 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Upper Wield, as everywhere, external mastic is only as good as the preparation behind it.

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
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.
Common problems we fix in Upper Wield
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The problems people generally mention when they call include:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
For an older house near a landmark such as Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
