Bitchet Green External Mastic
Movement joints in Bitchet Green need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
Do you need external mastic in Bitchet Green?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
It’s worth asking for a quote if you see:
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
- Joints with sealant missing in places
For site and facilities teams at buildings such as St Lawrence Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

We work on concrete & block, render & cladding joints and façade panels, and common reasons people get in touch are panel joints letting water in and movement joints with cracked, split or missing sealant.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Can you seal joints between render and window frames?

How much does external mastic cost in Bitchet Green?

Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Bitchet Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Why us?
- Over 20 years’ experience

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Ask before painting over external sealant
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.

External mastic in Bitchet Green: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Ightham Mote (about 1 mile south-east) nearby, there’s older building stock in the area around Bitchet Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as St Lawrence, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Kemsing station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
