- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
External mastic for homes and businesses in Childrey
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint doesn’t stand out. If you are dealing with rigid filler in a joint that should flex and failed sealant between panels on a façade, we can help.
Older homes in small places like Childrey may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Whatever the size of the job, it’s backed by our one-year guarantee.

Signs you need external mastic in Childrey
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
The problems people usually mention when they call are:
- Panel joints letting water in
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
For site and facilities teams at buildings such as The Ridgeway Church of England (C) Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. 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 like Childrey needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The size of the job
- When we can work, for business premises
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
When you call or email, these details help:
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or drop us an email.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Older cottages and farmhouses around Childrey can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why us?
- Colour agreed with you before we start
- Anti-fungal sanitary silicone in wet areas
- ARBOMaster approved applicator
- 20+ years of sealant experience

Walls and rooflines in Childrey
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured.
