The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Broad Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Move anything stored near the joints
- Mention any tricky access
- Keep children and pets away from the work area
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Advice
External mastic for homes and businesses in Broad Green
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 façade panels, copings & trims and brickwork movement joints, and people most often call us about failed seals between different materials and plants rooting in failed movement joints.
Somewhere as small as Broad Green, homes and farm buildings often face open ground, 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.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

What external mastic looks like in Broad Green
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 Layer Marney Tower (about 4.6 miles south-east) nearby, there’s older building stock in the area around Broad Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of St James include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Marks Tey station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Honywood Community Science School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents and landlords in Broad Green can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

How to look after the new joints
To keep the joints looking good and working properly:
- Check external joints each spring
- Do not let climbing plants root in the sealant
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
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 early resealing is worth it.
Questions from Broad Green
Will you come out to Broad Green?
Yes, Broad Green is covered. 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.
I let a flat near Marks Tey station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What sealant work cannot fix
We won’t take on work that will not last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Render & cladding joints
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
Why it’s worth doing now in Broad Green
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. Where a wall is exposed, as many are in small places like Broad Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
