How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
External mastic for homes and businesses in Chilmington Green
For buildings in Chilmington Green, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have joints where the bead has come unstuck and panel joints letting water in, we can help, whatever the surface.
Somewhere as small as Chilmington Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In a small place like Chilmington Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Clear the area around the work
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
- Show decorators and builders where the movement joints are
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
FAQs for Chilmington Green
Do you cover smaller places like Chilmington Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Ashford International station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Common problems we fix in Chilmington Green
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Keep an eye out for these signs:
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Sealant that has lost its bond to the brick or render
Letting a property close to Ashford International station? Then split movement joints are easy to miss on a rental until damp shows inside.

What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Chilmington Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Walls and rooflines in Chilmington Green
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Godinton House (about 1.9 miles north) are a reminder that the area around Chilmington Green 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.
For an older house near a landmark such as Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Great Chart Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
