How we handle external mastic in Chiddingstone Causeway
On houses, flats and commercial buildings across Chiddingstone Causeway, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on joints between brick and frames, copings & trims and façade panels, and common reasons people get in touch are gaps where render, brick and frames meet and water getting into walls through failed joints.
In a village or hamlet like Chiddingstone Causeway, 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.
Big or small, you get the same 12-month guarantee in Chiddingstone Causeway and across Kent.

What external mastic looks like in Chiddingstone Causeway
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Chiddingstone Castle (about 1.5 miles south-west) are a reminder that the area around Chiddingstone Causeway has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of St Luke include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Penshurst station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Chiddingstone Causeway, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Façade panels
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
- Act on the first splits you see
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Chiddingstone Causeway, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas

Chiddingstone Causeway questions
Can you do external mastic in Chiddingstone Causeway?
Yes, Chiddingstone Causeway is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
I let a flat near Penshurst station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Where do you work from?
We work from Crawley. Our applicators cover Chiddingstone Causeway, along with the rest of our area.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you need from me for a quote?
Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
