West Yoke External Mastic
Professional external mastic in and around West Yoke, with every bit of old sealant taken out first.
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
- Failed seals between different materials
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal
- Brickwork movement joints
- Copings & trims
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
About our external mastic in West Yoke
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you have weathered mastic that no longer stretches and joints pointed up with cement by mistake, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in West Yoke is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for West Yoke
Can you help a landlord with a rental near Longfield station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can you do external mastic in West Yoke?
Yes. Our work covers London and the South East, and West Yoke is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Are you fully insured?
Yes. We are fully insured for every job we do.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Outside joints around West Yoke
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. Historic houses like Lullingstone Castle (about 4.4 miles west) are a reminder that the area around West Yoke has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as New Ash Green Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Parish Church of Saint Peter and Saint Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
- Keep movement joints as flexible joints, not mortar
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.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

Why act early in West Yoke
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like West Yoke, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Do you need external mastic in West Yoke?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Look out for any of the following:
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
Letting a property close to Longfield station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as West Yoke, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Mention if the joints have been sealed before

Advice
How we quote for external mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- The number and length of the joints
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- What’s wrong with the joints now
- Any access issues, like height or stairs
We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details and send pictures if you have them.
