External mastic for homes and businesses in Tingewick
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. If you have moss and dirt in joints with no sealant left and sealant that has lost its bond to the brick or render, we can put it right.
Around Tingewick, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You get a 12-month guarantee, the same in Tingewick as everywhere else we work.

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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.

Walls and rooflines in Tingewick
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stowe House (about 3.1 miles north) are a reminder that the area around Tingewick has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St Mary Magdalen, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we are called out for in Tingewick
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Any of these means the joints need attention:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
If you look after a building such as Royal Latin School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before booking
- Whether they seal over old material or remove it
- Is VAT in the price?
- Whether they’re fully insured
- How much experience the applicator has
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure movement joints aren’t pointed over
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
How the visit works
There’s no need to move everything out, 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. For a village or hamlet like Tingewick, 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.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Advice
What sealant work cannot fix
We will always be straight with you, so here’s what new sealant won’t do:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.
