About our external mastic in Linwood
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 where a rigid filler would soon crack. We work on concrete & block, façade panels and brickwork movement joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and brick movement joints where the sealant has split.
External sealant needs dry, clean surfaces, so work around Linwood is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, large or small.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Leave the joints unpainted unless we have said otherwise
- Show decorators and builders where the movement joints are
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Common problems we fix in Linwood
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Gaps where render, brick and frames meet
- Panel joints letting water in
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
In and around Linwood, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Linwood, 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.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any tricky access
- Let us know about parking restrictions
- Mention if the joints have been sealed before

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How do I get a quote for external mastic in Linwood?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Linwood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- We’re fully insured
- Homes, businesses and hotels
- Approved under the ARBOMaster scheme
