External mastic in Broad Tenterden
For buildings in Broad Tenterden, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have plants rooting in failed movement joints and movement joints with cracked, split or missing sealant, we can help, on brickwork movement joints, render & cladding joints and joints between brick and frames alike.
Older homes in small places like Broad Tenterden may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job.

Broad Tenterden buildings and the weather
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. Historic houses like Smallhythe Place (about 1.6 miles south) are a reminder that the area around Broad Tenterden 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.
If you look after a building such as Tenterden Church of England Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Surface by surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
The process
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. The work usually takes anything from a few hours to several days, depending on the building. Somewhere as small as Broad Tenterden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Common questions in Broad Tenterden
Do you cover smaller places like Broad Tenterden?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Broad Tenterden in your area for external mastic?
Yes. We work across London and the South East, and Broad Tenterden is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Why act early in Broad Tenterden
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. In a small place like Broad Tenterden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

- 4.9 on Google from 180+ five-star reviews

Common problems we fix in Broad Tenterden
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Signs it’s time to call us include:
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
In the older streets around Parish Church of St Mildred, the joints between older walls, newer extensions and the roofline need a sealant that can move.
