- Failed render or damaged cladding panels

- Cracking across the wall rather than at a joint
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

External mastic in Upper Green
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you have joints pointed up with cement by mistake and moss and dirt in joints with no sealant left, we can put it right, on copings & trims, concrete & block and render & cladding joints alike.
External sealant needs dry, clean surfaces, so work around Upper Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a one-year guarantee, the same in Upper Green as everywhere else we work.

External mastic in Upper Green: local notes
Historic houses like Stargroves (about 2.9 miles south-east) are a reminder that the area around Upper Green has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Inkpen Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Michael include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.
Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
What we are called out for in Upper Green
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.
Signs it’s time to call us include:
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
For landlords with property near Kintbury station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Are they insured?
- When the joint can take water or movement
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. For a village or hamlet like Upper Green, the journey is planned in advance: 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 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.
- 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
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Why act early in Upper Green
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Upper Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Why book with us
- ARBOMaster approved applicator
- We never seal over old sealant
- Anti-fungal silicone where joints get wet
- Fully insured
