How we handle external mastic in Fosten Green
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you’re dealing with movement joints filled with mortar instead of sealant and rain getting behind render or cladding at a joint, we can help, on concrete & block, brickwork movement joints and façade panels alike.
Somewhere as small as Fosten Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.
Fosten Green: your questions answered
I let a flat near Headcorn station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Fosten Green within the area you cover?
Yes, Fosten 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.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Are you insured?
Yes, we are fully insured for every job we do.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a village or hamlet like Fosten Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
If you manage several properties in or around Fosten Green, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Adding movement joints to masonry that has none
- Damp that is not coming from the joint
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Why act early in Fosten Green
Done well, a resealed joint is a neat, straight line 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 Fosten Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

Letting a property close to Headcorn station? Then split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Margaret's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
