- Movement joints with cracked, split or missing sealant
External mastic in Leigh Green, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. Typical jobs include rain getting behind render or cladding at a joint and weathered mastic that no longer stretches, across render & cladding joints, façade panels and brickwork movement joints.
Somewhere as small as Leigh Green, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
You get a 12-month guarantee, the same in Leigh Green as everywhere else we work.

The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Any working-time requirements on site
- The type of sealant required
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- The rough size of the job
- If someone has resealed it before
- A few photos by email, if you can
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or email us.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Walls and rooflines in Leigh Green
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 Smallhythe Place (about 1.9 miles south) nearby, there’s older building stock in the area around Leigh Green 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.
For site and facilities teams at buildings such as Tenterden Church of England Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Appledore (Kent) station? Then split movement joints are easy to miss on a rental until damp shows inside.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
Signs you need external mastic in Leigh Green
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch when they notice one of these:
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Parish Church of St Mildred, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- What insurance they hold
- Is VAT in the price?
What the job involves on each surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Leigh Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
