Stonestreet Green questions
Will you come out to Stonestreet Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Stonestreet Green for external mastic?
Yes, Stonestreet Green is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
How we handle external mastic in Stonestreet Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on brickwork movement joints, concrete & block and render & cladding joints, and people most often call us about rigid filler in a joint that should flex and weeds or debris growing in open joints.
In a village or hamlet like Stonestreet Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Every job comes with a 12-month guarantee, wherever you are in Kent.

What external mastic looks like in Stonestreet Green
Historic houses like Westenhanger Castle (about 3.7 miles east) are a reminder that the area around Stonestreet Green has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Westenhanger station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Martin include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Aldington Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damp that isn’t coming from the joint
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Copings & trims
- Concrete & block
- Render & cladding joints
What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Wash walls gently around the sealant
- Point out the joints to other trades
- Act on the first splits you see
- Don’t let climbing plants root in the sealant
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Why it’s worth doing now in Stonestreet Green
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Stonestreet Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
