External mastic in Durrant Green, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have sealant that has lost its bond to the brick or render and weeds or debris growing in open joints, we can put it right.
External sealant needs dry, clean surfaces, so work around Durrant Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a 12-month guarantee, the same in Durrant Green as everywhere else we work.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What external mastic looks like in Durrant Green
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. Historic houses like Smallhythe Place (about 4.3 miles south) are a reminder that the area around Durrant Green 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.
For an older house near a landmark such as Church of St Michael, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like St Michael's Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Make sure movement joints aren’t pointed over
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Do you need external mastic in Durrant Green?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People generally contact us after spotting one of these:
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
Rented homes near Pluckley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

- Are they insured?
- What guarantee comes with the work

What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
