Problem with your movement joints in Benenden? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

External mastic in Benenden, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We are often asked to deal with plants rooting in failed movement joints and brick movement joints where the sealant has split, across concrete & block, brickwork movement joints and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Benenden is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

You’ll get a clear quote before any work starts. It’s based on:
- The size of the job
- Which sealant suits the joint
- Mould in or behind the old joints
- The old material and how stubborn it is
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Questions from Benenden
Do you cover smaller places like Benenden?
Yes, Benenden is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Benenden in your area for external mastic?
Yes, Benenden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
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 are you based?
Mr Mastic is based in Crawley. We cover Benenden and the rest of Kent, along with the rest of our area.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
How the visit works
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a small place like Benenden, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

When to call us in Benenden
Buildings move more than people expect. 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.
People usually contact us when they notice something like this:
- Failed seals between different materials
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
If you look after a building such as Benenden Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- How the joint is cleaned and prepared
- How much experience the applicator has
- What happens if they find a problem under the old sealant
- Whether VAT is included
Walls and rooflines in Benenden
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. With historic houses such as Great Dixter (about 5 miles south) nearby, there’s older building stock in the area around Benenden as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Church of St George, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a small place like Benenden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, 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.
