External Mastic in Minster Lovell
Professional external mastic in and around Minster Lovell, with every bit of old sealant taken out first and a one-year guarantee.
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
- Panel joints letting water in
How we handle external mastic in Minster Lovell
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on copings & trims, brickwork movement joints and façade panels, and common reasons people get in touch are movement joints filled with mortar instead of sealant and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in Minster Lovell is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep movement joints as flexible joints, not mortar
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

Signs you need external mastic in Minster Lovell
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
It’s worth asking for a quote if you see:
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
For site and facilities teams at buildings such as St Kenelm's Church of England (VC) School, its movement joints, gutters and trims need looking after like any other building’s.

Walls and rooflines in Minster Lovell
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Minster Lovell Hall (about 0.8 miles north-east) are a reminder that the area around Minster Lovell 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.
Homes close to Church of Saint Kenelm include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
