Movement joints in Chiltington need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

How we handle external mastic in Chiltington
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have joints pointed up with cement by mistake and moss and dirt in joints with no sealant left, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around Chiltington is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Your questions about external mastic in Chiltington
Do you cover Chiltington for external mastic?
Yes, Chiltington is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
I let a flat near Cooksbridge station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
How long does the job take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We will confirm how long when we quote.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.
How do you reach high-level joints?
Each building is different. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep high-pressure jets off the joints
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
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.
How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere like Chiltington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. In a small place like Chiltington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Walls and rooflines in Chiltington
Historic houses like Anne of Cleves House (about 3.7 miles south) are a reminder that the area around Chiltington has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Cooksbridge station? Then split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near The Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
