How we handle external mastic in Glenburn
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on render & cladding joints, concrete & block and brickwork movement joints, and common reasons people get in touch are joints where the bead has come unstuck and movement joints with cracked, split or missing sealant.
External sealant needs dry surfaces, so outdoor work around Glenburn is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Every job comes with our one-year guarantee, wherever you are in Renfrewshire.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours to a few days, depending on the length of joint and the access. Around Glenburn, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- For business premises, tell us about site rules or sign-in

Why deal with it now?
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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
