How we handle external mastic in Badlesmere
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. If you have movement joints with cracked, split or missing sealant and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Somewhere as small as Badlesmere, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, you get the same 12-month guarantee in Badlesmere and across Kent.

Questions from Badlesmere
I let a flat near Selling station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can you do external mastic in Badlesmere?
Yes. Our work covers London and the South East, and Badlesmere 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 quote.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. For a village or hamlet like Badlesmere, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Leave the joints unpainted unless we’ve said otherwise
- Keep high-pressure jets off the joints
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
When something else is needed
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.

What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- How easy the joints are to reach
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Photos by email, if that is easy
- Any access issues, like height or stairs
- The problem you’ve noticed
- Any previous sealing or DIY work
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
Walls and rooflines in Badlesmere
With historic houses such as Belmont House and Gardens (about 1.9 miles north-west) nearby, there’s older building stock in the area around Badlesmere 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Sheldwich Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Leonard, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Do you need external mastic in Badlesmere?
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
If you let a flat or house near Selling station, split movement joints are easy to miss on a rental until damp shows inside.
