Signs you need external mastic in Fullwell Cross
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
Managing a site like Clore Tikva School? Then its movement joints, gutters and trims need looking after like any other building’s.

External mastic in Fullwell Cross
On houses, flats and commercial buildings across Fullwell Cross, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on copings & trims, concrete & block and brickwork movement joints, and common reasons people get in touch are sealant pulling away from one side of the joint and rain getting behind render or cladding at a joint.
Around Fullwell Cross, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Outside joints around Fullwell Cross
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Valentines Mansion (about 1.8 miles south-west) nearby, there’s older building stock in the area around Fullwell Cross as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to St Francis of Assisi include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Seven Kings station? Then split movement joints are easy to miss on a rental until damp shows inside.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Parking around Fullwell Cross is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Clear items away from the joints we’re working on

Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Common questions in Fullwell Cross
Do you cover smaller places like Fullwell Cross?
Yes. Fullwell Cross is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Seven Kings station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How do I get a quote for external mastic in Fullwell Cross?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Keeping the joints in good condition
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. 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 Fullwell Cross
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In a smaller place like Fullwell Cross, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
