External mastic in Chiddingstone Hoath
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include joints where the bead has come unstuck and water getting into walls through failed joints, on brickwork movement joints, concrete & block and façade panels.
Outside joints can only be sealed when they’re dry, so work in Chiddingstone Hoath is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee.

Surface by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Your questions about external mastic in Chiddingstone Hoath
Will you come out to Chiddingstone Hoath?
Yes. Chiddingstone Hoath is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Chiddingstone Hoath?
Yes. We work across London and the South East, and Chiddingstone Hoath is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Where do you work from?
We work from Crawley. We cover Chiddingstone Hoath and the rest of Kent.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a village or hamlet like Chiddingstone Hoath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

Related advice
Landlords, agents and businesses in Chiddingstone Hoath
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Façade panels

External mastic in Chiddingstone Hoath: local notes
With historic houses such as Chiddingstone Castle (about 1.6 miles north) nearby, there’s older building stock in the area around Chiddingstone Hoath as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Chiddingstone Castle, about 1.6 miles north, is one of the historic houses in the wider area around Chiddingstone Hoath. If you let a flat or house near Cowden station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Chiddingstone Hoath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
