External mastic for homes and businesses in Biddenden Green
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. If you have joints where the bead has come unstuck and joints with sealant missing in places, we can help, whatever the surface.
Around Biddenden Green, 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.
Whatever the size of the job, it’s backed by our one-year guarantee in Biddenden Green and across Kent.

What we are called out for in Biddenden Green
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- 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 live in an older home near Church of St Michael, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in Biddenden Green: local notes
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.
For landlords with property near Pluckley station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Smarden Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear growth from the base of walls and joints
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we’ve said otherwise
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.

Biddenden Green questions
Can you help a landlord with a rental near Pluckley station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Biddenden Green?
Yes, Biddenden Green is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
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. We choose one that suits both surfaces.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Biddenden Green needs a little journey planning: let us know about lanes, gates and parking. 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
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
