External mastic for homes and businesses in Tillington
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Common call-outs are for rigid filler in a joint that should flex and moss and dirt in joints with no sealant left, across façade panels, copings & trims and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Tillington is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the 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.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check external joints each spring
- Leave the joints unpainted unless we’ve said otherwise
- Clear growth from the base of walls and joints
- Have failed joints looked at early
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
Common problems we fix in Tillington
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us include:
- Panel joints letting water in
- Failed seals between different materials
- Plants rooting in failed movement joints
- Sealant pulling away from one side of the joint
Managing a site like Petworth Cof E Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Advice
Tillington buildings and the weather
Historic houses like Petworth House (about 0.8 miles east) are a reminder that the area around Tillington has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to The Parish Church of All Hallows include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
