Walls and rooflines in Bethersden
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Godinton House (about 4 miles north-east) nearby, there’s older building stock in the area around Bethersden as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Margaret, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Pluckley station, outside joints that have cracked can let damp into a rental, so check them between lets.

About our external mastic in Bethersden
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Common call-outs are for failed sealant between panels on a façade and damp patches traced to an open external joint, on joints between brick and frames, copings & trims and concrete & block.
Around Bethersden, 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.
Our work is backed for twelve months, in Bethersden and everywhere else we cover.

Landlord and commercial work in Bethersden
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Aftercare tips
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Common questions in Bethersden
Can you help a landlord with a rental near Pluckley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is Bethersden within the area you cover?
Yes. Bethersden 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.
Do you use backing rod?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
How much does external mastic cost in Bethersden?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll say how long yours will take.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. Around Bethersden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
What we are called out for in Bethersden
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us are:
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
If you look after a building such as Bethersden Primary School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether they’re fully insured
- Whether they seal over old material or remove it
- How the colour is chosen
- What happens if they find a problem under the old sealant
Can I do it myself?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Bethersden, access is often the only tricky part. 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.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
