External mastic in Turners Hill, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and people most often call us about sealant pulling away from one side of the joint and moss and dirt in joints with no sealant left.
Around Turners Hill, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
All of our work is guaranteed for twelve months, in Turners Hill and everywhere else we cover.

When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long does external mastic take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Turners Hill, 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.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints

External mastic in Turners Hill: local notes
Historic houses like Gravetye Manor (about 1.6 miles south-east) are a reminder that the area around Turners Hill has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Leonard, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to East Grinstead station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What the job involves on each surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Concrete & block
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
Signs you need external mastic in Turners Hill
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Sealant pulling away from one side of the joint
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
Managing a site like Turners Hill CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
