About our external mastic in West Green
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. Common call-outs are for joints where the bead has come unstuck and plants rooting in failed movement joints, across copings & trims, render & cladding joints and façade panels.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in West Green, tell us how high the joints are and how to reach the back of the building.
All our work comes with our 12-month guarantee.

External mastic in West Green: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Bruce Castle (about 1.1 miles north-east) nearby, there’s older building stock in the area around West Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like West Green Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Philip the Apostle, older walls, gutters and the joints where extensions meet them need a flexible sealant. As a London address, West Green can be tricky for parking: let us know about parking bays, permits or a driveway.

Aftercare tips
After the cure time, these simple habits help:
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we can’t put right
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Movement that’s more than a sealant joint can take
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

What else we do in West Green
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. For a job in West Green, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- 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
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Questions from West Green
Can you help a landlord with a rental near Seven Sisters station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is parking a problem for a job in West Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Do you work in West Green?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes West Green.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Different surfaces, different methods
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
What affects the quote in West Green
Your quote is based on your job. We look at:
- Whether the work is at height
- The type of sealant required
- Any mould that needs treating
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
To make quoting easier, let us know:
- The type of property
- The rough size of the job
- Where the job is, and your postcode
- Photos by email, if that is easy
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
