External mastic in East Cholderton
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Typical jobs include rigid filler in a joint that should flex and joints with sealant missing in places, on joints between brick and frames, render & cladding joints and façade panels.
Around East Cholderton, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Walls and rooflines in East Cholderton
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Grateley station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Amport Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How it works
Before we leave, we go over the finished joints with you. The work 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. In a small place like East Cholderton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams in East Cholderton and across Hampshire. Several sites can be quoted together.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Honest limits
We’ll always be straight with you, so here’s what sealant can’t fix:
- Cracked brickwork or render that needs a builder or plasterer
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.
Surfaces we seal
- Façade panels
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
Why act early in East Cholderton
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like East Cholderton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Yes, East Cholderton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Will you come out to East Cholderton?
Yes, East Cholderton is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it does not stand out.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
