Sealing brickwork movement joints, render, cladding and façade joints for East Hendred, backed by a one-year guarantee. Ask us for a quote.
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as East Hendred, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.

External mastic in East Hendred, done properly
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. If you are dealing with sealant pulling away from one side of the joint and leaking joints around cladding and façade panels, we can help.
External sealant needs dry, clean surfaces, so work around East Hendred is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

Keeping the joints in good condition
Aftercare is simple:
- Check external joints each spring
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Never let anyone fill a movement joint with 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.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Why deal with it now?
Water gets in through a failed movement joint. 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 East Hendred, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

FAQs for East Hendred
Is East Hendred in your area for external mastic?
Yes. We work across London and the South East, and East Hendred is part of that. Just call 0345 464 0079 or email us with a few details of the job.
I let a flat near Didcot Parkway station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What external mastic looks like in East Hendred
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.
If you live in an older home near Church of St Augustine of Canterbury, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as The Hendreds Church of England School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Didcot Parkway station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints

Surface by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
