Wooburn Green External Mastic
Problem with your movement joints in Wooburn Green? We remove the old material, prepare the joints and seal them properly.
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Walk round the building once a year and look at the joints
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
External mastic in Wooburn Green, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have panel joints letting water in and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
Houses in smaller places like Wooburn Green can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How the visit works
At the end, we look at the finished work together. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In a smaller place like Wooburn Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Advice
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. In an older home around Wooburn Green, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Walls and rooflines in Wooburn Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Cliveden (about 2.6 miles south) nearby, there’s older building stock in the area around Wooburn Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around St Mary's Pastoral Centre, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Wooburn Green Primary School, its movement joints, gutters and trims need looking after like any other building’s.
