How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
External mastic for homes and businesses in Bryant's Bottom
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We are often asked to deal with plants rooting in failed movement joints and cracked joints where brick meets render or frames, on copings & trims, façade panels and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Bryant's Bottom is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Bryant's Bottom needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Clear items away from the joints we are working on

Common problems we fix in Bryant's Bottom
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
It’s worth asking for a quote if you see:
- Failed seals between different materials
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
If you let a flat or house near Great Missenden station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- Whether you can choose the colour

Leave it or put it right?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Bryant's Bottom, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before we start.

Questions from Bryant's Bottom
Can you do external mastic in Bryant's Bottom?
Yes. Our work covers London and the South East, and Bryant's Bottom is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Great Missenden station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Bryant's Bottom buildings and the weather
With historic houses such as Hughenden Manor (about 2.8 miles south) nearby, there’s older building stock in the area around Bryant's Bottom as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Speen CofE VA School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Speen Church (Baptist) include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Tell anyone working on the walls about the movement joints
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
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.
