External Mastic in Nettlestead
We cover Nettlestead for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work normally takes anything from a few hours to several days, depending on the building. In a small place like Nettlestead, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

Advice
External mastic for homes and businesses in Nettlestead
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you’re dealing with movement joints with cracked, split or missing sealant and leaking joints around cladding and façade panels, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Nettlestead is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What affects the quote in Nettlestead
There’s no set price list. The quote depends on:
- Which sealant suits the joint
- Any working-time requirements on site
- The size of the job
- Whether the work is at height
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Walls and rooflines in Nettlestead
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 Old Soar Manor (about 4.3 miles west) nearby, there’s older building stock in the area around Nettlestead as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Wateringbury Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Wateringbury station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Nettlestead: your questions answered
Do you work for landlords with property near Wateringbury station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Nettlestead?
Yes. Nettlestead is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you fully insured?
Yes. We are fully insured.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Movement that is more than a sealant joint can take
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Copings & trims
- Brickwork movement joints

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep high-pressure jets off the joints
- Don’t let climbing plants root in the sealant
- Check external joints each spring
- Act on the first splits you see
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Why it’s worth doing now in Nettlestead
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Nettlestead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Common problems we fix in Nettlestead
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
If you live in an older home near St Mary's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
