- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Failed seals between different materials
The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Ellisfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Clear the area around the work

Advice
About our external mastic in Ellisfield
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have moss and dirt in joints with no sealant left and joints pointed up with cement by mistake, we can put it right, on façade panels, brickwork movement joints and copings & trims alike.
In a village or hamlet like Ellisfield, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

What happens if it’s left?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Ellisfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What we are called out for in Ellisfield
A lot of failed joints come down to preparation: 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.
Common reasons people contact us include:
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
If you let a flat or house near Basingstoke station, split movement joints are easy to miss on a rental until damp shows inside.
Before booking anyone
- Whether they’re fully insured
- Whether the sealant suits the joint
- How long to leave it before use
- Whether all the old sealant comes out first
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Tell us what the building has when you get in touch.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
Looking after it afterwards
After the cure time, these simple habits help:
- Make sure movement joints aren’t pointed over
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
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.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.

What external mastic looks like in Ellisfield
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. With historic houses such as Hall Place (about 3.9 miles south) nearby, there’s older building stock in the area around Ellisfield as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St. Martin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What do you need from me for a quote?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
