External mastic in Luddesdown
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, so it bonds to the two sides only and can stretch. If you are dealing with old sealant gone brittle and cracked and joints with sealant missing in places, we can put it right, on render & cladding joints, copings & trims and brickwork movement joints alike.
Around Luddesdown, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee.

What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work starts. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Luddesdown, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.

What external mastic looks like in Luddesdown
With historic houses such as Cobham College (about 1.2 miles north) nearby, there’s older building stock in the area around Luddesdown as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Parish Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Meopham School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a small place like Luddesdown, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When to call us in Luddesdown
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
Rented homes near Sole Street station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- What the quote includes, VAT included or not
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
