External & façade joints in Stocks Green, Kent
Movement joints in Stocks Green need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Failed sealant between panels on a façade
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
External mastic for homes and businesses in Stocks Green
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We are often asked to deal with weathered mastic that no longer stretches and gaps where render, brick and frames meet, across copings & trims, render & cladding joints and brickwork movement joints.
Older homes in small places like Stocks Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Common problems we fix in Stocks Green
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us are:
- Joints where the bead has come unstuck
- Failed seals between different materials
- Brick movement joints where the sealant has split
- Panel joints letting water in

The process
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. For a village or hamlet like Stocks Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Advice
Questions from Stocks Green
Can you help a landlord with a rental near Hildenborough station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can you do external mastic in Stocks Green?
Yes, Stocks Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins, matched as closely as the range allows.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How do I get a quote for external mastic in Stocks Green?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Check external joints each spring
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Walls and rooflines in Stocks Green
With historic houses such as Penshurst Place (about 3.2 miles south-west) nearby, there’s older building stock in the area around Stocks 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Hildenborough Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Parish Church of St John, an extension built onto an older house moves differently, and the joint between them takes the strain.

What else we do in Stocks Green
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Stocks Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
