External mastic in Barnes Street, done properly
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on joints between brick and frames, copings & trims and concrete & block, and people most often call us about failed sealant between panels on a façade and movement joints with cracked, split or missing sealant.
In a village or hamlet like Barnes Street, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Barnes Street: your questions answered
Will you come out to Barnes Street?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Beltring station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.

Signs you need external mastic in Barnes Street
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
People normally contact us when they notice something like this:
- Damp patches traced to an open external joint
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
If you live in an older home near Golden Green Mission Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before booking anyone
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Which colour the sealant will be
- Is VAT in the price?
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Barnes Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Façade panels
- Copings & trims
Looking after it afterwards
So the new joints stay in good condition:
- Point out the joints to other trades
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
