External mastic in Wooburn
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Typical jobs include leaking joints around cladding and façade panels and joints with sealant missing in places, on copings & trims, façade panels and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Wooburn is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
- Don’t let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Common problems we fix in Wooburn
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
The most common problems we see are:
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
For landlords with property near Bourne End station, outside joints that have cracked can let damp into a rental, so check them between lets.

External mastic in Wooburn: local notes
Historic houses like Cliveden (about 1.5 miles south) are a reminder that the area around Wooburn has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
For an older house near a landmark such as Church of St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like St Paul's Church of England Combined School? Then larger buildings have long runs of movement joint that eventually need resealing.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Wooburn 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

- Tell us about any water getting in
- Let us know about earlier repairs to the joints
